DP83902AVLJ Ringkasan

The Texas Instruments DP83902AVLJ is a serial network interface controller for twisted-pair networks, supplied in a 100-lead rectangular QFP package and operating from a 4.75 V to 5.25 V supply. Its listed characteristics include a serial interface, approximately 140 mA supply current, commercial temperature grade, and tray packaging. The device is described by Texas Instruments as an ST-NIC serial network interface controller and is categorized as an obsolete interface controller.

A serial network interface controller is an integrated circuit that manages the communication path between a computer or embedded system and a network medium. In the product hierarchy, this controller belongs to interface ICs and ultimately to the broader semiconductor category. The DP83902AVLJ was designed around twisted-pair network connectivity, where a physical-layer transceiver is commonly paired with a controller. The controller handles network framing and data exchange, while the external transceiver performs signal encoding, reception, and electrical isolation from the copper medium.

The DP83902AVLJ uses a 4.75 V minimum and 5.25 V maximum supply voltage, giving system designers a nominal 5 V operating rail. The verified distributor listing reports a supply current of 140 mA. Its 100-pin QFP package provides a substantial number of external connections, which is typical for legacy Ethernet controllers that require parallel host data paths, address and control signals, clocking, interrupt signaling, and twisted-pair transceiver interfaces. Package dimensions, pin names, operating-temperature limits, Ethernet data rate, transceiver interface details, and electrical timing limits are not included in the supplied verification data.

The DP83902AVLJ is most relevant to legacy networking equipment, industrial control systems, embedded controllers, and industrial Ethernet designs that already use this controller and its associated application circuitry. It should not be assumed interchangeable with a modern Ethernet controller merely because both perform networking functions. The verified cross-reference material specifically states that the STMicroelectronics SERC816/TR is not a direct drop-in replacement because its pinout, internal biasing, and MII timing characteristics differ. A PCB replacement therefore requires a detailed electrical, timing, and pin-level review rather than a simple component substitution.

This page consolidates the verified distributor specifications, lifecycle information, sourcing details, and replacement constraints for DP83902AVLJ. Pricing is presented as unavailable because the verified sources provide quote or request-for-quotation terms rather than numeric unit prices. The pin table records all 100 package terminals but marks individual terminal names as unavailable rather than guessing pin functions. Engineers should obtain the manufacturer datasheet and original design reference before layout changes, firmware updates, or obsolescence redesigns.

Legacy Industrial Ethernet Control

The DP83902AVLJ is appropriate for maintaining a legacy industrial Ethernet controller board whose original design already uses its 100-terminal QFP device, 5 V supply, and associated driver software. Its verified 4.75 V to 5.25 V operating range suits a regulated 5 V rail, while the reported 140 mA supply current identifies the load that the system power design must accommodate. Because the part is obsolete, the strongest use case is repair or continuation of proven equipment rather than new platform development. Engineers should preserve the original schematic, board revisions, transceiver selection, and firmware configuration when sourcing a replacement or redesigning around a supported controller.

🧩

Embedded Twisted-Pair Networking

The DP83902AVLJ can support an existing embedded system that uses a dedicated serial network interface controller for twisted-pair communication. Its serial interface and commercial temperature grade match the role of a general-purpose networking controller, while the 4.75 V to 5.25 V supply range requires a stable nominal 5 V source in the host design. The verified 140 mA supply-current figure is important when budgeting the controller rail. Designers should not reuse a modern Ethernet PHY by assumption; the controller-to-transceiver signal definitions, timing, isolation, magnetics, and software interface must be confirmed against the original system documentation.

Legacy Network Interface Card Repair

The DP83902AVLJ is relevant to repair and continuation sourcing for legacy network interface cards built around the DP83902A family. The verified catalog data identifies the package as a 100-BFQFP supplied in a tray, allowing engineers to check board compatibility before procurement. Its obsolete lifecycle status means that inventory may be limited, and quotation sellers should be asked about factory-sealed status, traceability, date code, and storage history. Before installation, verify that the replacement has the correct suffix, package terminal arrangement, supply requirements, and transceiver compatibility rather than relying only on the base device description.

Server and Switch Spare Parts

A DP83902AVLJ may be used in selected spare-part workflows for older server, switch, or network-adapter hardware that originally incorporated the controller. The 100-QFP package and obsolete status mean that procurement teams need exact board-level confirmation before treating the device as a universal spare. The verified 5 V supply range and 140 mA current provide initial electrical screening, but they do not establish temperature grade limits or data-rate suitability. Maintain the original manufacturer part number in approved vendor lists, require traceability where required, and test every replacement board at the interfaces affected by the network controller.

Network Test Equipment

The DP83902AVLJ may appear in legacy network test equipment or protocol analyzers that were designed around a dedicated twisted-pair serial controller. Such equipment often depends on exact timing and software behavior, making the original part preferable when repairing an unchanged platform. Its reported 140 mA supply current and 5 V operating range help identify the correct power section during fault analysis. For new test equipment, however, engineers should evaluate currently supported controllers with documented driver APIs and current sourcing. Any migration requires comparison of media access behavior, frame handling, bus timing, interrupt latency, and host-platform compatibility.

Obsolescence Continuity Engineering

The DP83902AVLJ is directly relevant to obsolescence management because it is verified as obsolete while still appearing at distributors with reported inventory and quotation-based fulfillment. Continuity engineers can use the 100-BFQFP package, 4.75 V to 5.25 V supply range, and 140 mA supply current to identify affected assemblies. The absence of verified drop-in alternatives means a resilience plan may require a last-time-buy decision, retained stock, board respin, or software-supported controller migration. The SERC816/TR may inform functional redesign, but its verified pinout, biasing, and MII timing differences prevent treating it as a no-change substitution.

What is the DP83902AVLJ?

The DP83902AVLJ is a Texas Instruments serial network interface controller for twisted-pair networks, supplied in a 100-QFP package. The verified DigiKey and DigChips listings identify its interface as serial, its supply range as 4.75 V to 5.25 V, and its supply current as 140 mA. It belongs to the interface-controller category and was designed for legacy computer-networking and embedded systems requiring a dedicated network interface controller.

What is the operating voltage of the DP83902AVLJ?

The DP83902AVLJ operates from 4.75 V to 5.25 V, making it a nominal 5 V interface controller. The same verified specification also reports a supply current of 140 mA. Because the permitted operating range is narrow, the power rail should be regulated to 5 V within those limits. A specific tolerance, ripple requirement, and maximum operating dissipation are not present in the supplied data and must be checked in the manufacturer datasheet.

What package does the DP83902AVLJ use?

The DP83902AVLJ is offered in a 100-BFQFP package, described by DigiKey as a 100-QFP measuring 14 mm by 20 mm. Other verified catalog data identifies the package as rectangular QFP with gull-wing terminals. The component is supplied in a tray. Individual pin assignments are not included in the supplied results, so the 100-terminal record below intentionally uses data-needed markers instead of inventing terminal functions.

Is the DP83902AVLJ still active?

No. The verified Octopart comparison identifies DP83902AVLJ as obsolete. That status means new designs should not assume normal long-term production availability, while existing industrial and networking equipment may still require repair or continuation sourcing. Lifecycle status should be reconfirmed before a production commitment because obsolete components can remain available through surplus channels without receiving ordinary manufacturing notices.

Where can I download the DP83902AVLJ datasheet PDF?

The DP83902AVLJ datasheet PDF is available through the verified AllDataSheet archive at https://www.alldatasheet.com/datasheet-pdf/pdf/8364/NSC/DP83902AVLJ.html. The result identifies the document as the National Semiconductor DP83902A family datasheet and reports 70 pages. Because the legacy document is hosted by an archive rather than the current manufacturer domain, engineers should also consult Texas Instruments cross-reference resources and confirm document revision status before using it for a new design.

Where can I find the DP83902AVLJ pinout?

The DP83902AVLJ pinout must be obtained from the 100-pin DP83902A family datasheet linked by the verified AllDataSheet source. The package contains 100 gull-wing terminals, and no complete terminal-name table appears in the supplied search results. This page therefore lists terminals 1 through 100 but marks each function as data needed. Do not infer bus, power, clock, reset, or transceiver signals from neighboring parts because legacy Ethernet controllers may use nonstandard pin assignments.

What can replace the DP83902AVLJ?

No verified true drop-in replacement was identified for the DP83902AVLJ in the supplied cross-reference data. The STMicroelectronics SERC816/TR is functionally related, but the verified comparison explicitly says it is not a direct drop-in replacement because its pinout, internal biasing, and MII timing characteristics differ. Engineers should treat SERC816/TR as a redesign candidate only after checking supply requirements, timing, transceiver interfaces, software support, and PCB changes.

Is the SERC816/TR a drop-in replacement for the DP83902AVLJ?

No. The SERC816/TR is not a direct drop-in replacement for the DP83902AVLJ, according to the verified Digi-Electronics comparison. It differs in pinout, internal biasing, and MII timing characteristics, and it does not share the verified 100-BFQFP package arrangement. Both devices support 10 Mbps Ethernet operation, but functional equivalence does not establish PCB compatibility. A replacement project therefore requires schematic, layout, timing, and firmware validation.

What is the best STMicroelectronics equivalent for the DP83902AVLJ?

The STMicroelectronics SERC816/TR is the relevant web-identified equivalent candidate, but it is not a verified drop-in replacement for the DP83902AVLJ. The supplied source explicitly identifies differences in pinout, internal biasing, MII timing, and supply tolerance. Consequently, no STMicroelectronics part can be presented as a board-compatible alternative without a separate engineering review. The candidate may support a redesigned 10 Mbps twisted-pair Ethernet interface after compatibility testing.

DP83902AVLJ vs SERC816/TR — which is better for an existing PCB?

The DP83902AVLJ is the correct choice for preserving an existing PCB because the verified SERC816/TR data identifies it as not pin-compatible and therefore not a direct replacement. The SERC816/TR may be considered for a redesigned controller board after confirming electrical requirements and MII timing. Replacing the installed DP83902AVLJ with the SERC816/TR without changing the layout risks interconnection, biasing, timing, and firmware failures.

When should I choose the DP83902AVLJ over a modern Ethernet controller?

Choose the DP83902AVLJ only when maintaining an existing legacy design that already depends on its controller, driver, board layout, and 5 V network interface. It is generally unsuitable for new designs because the part is obsolete and the verified alternatives do not provide a pin-compatible upgrade. For new products, select a currently supported controller with appropriate Ethernet speed, software ecosystem, supply availability, package, and long-term sourcing rather than reproducing an obsolete architecture.

Is the DP83902AVLJ suitable for industrial networking equipment?

The DP83902AVLJ can be suitable for maintaining legacy industrial networking equipment because it is a commercial-grade twisted-pair serial network interface controller with a 4.75 V to 5.25 V supply range. The commercial temperature limits, Ethernet rate, protocol details, and long-term lifecycle availability are not supplied, so suitability cannot be confirmed for a specific industrial temperature range or network standard. Existing proven circuitry and its operating environment must be reviewed.

Where can I buy the DP83902AVLJ online?

The DP83902AVLJ is listed by DigiKey at https://www.digikey.com/en/products/detail/texas-instruments/DP83902AVLJ/212052 and by Heisener at https://www.heisener.com/ProductDetail/DP83902AVLJ. The Heisener result reported 8,484 pieces and an estimated delivery window as of the supplied 2026-10-28 retrieval. Because the part is obsolete and distributor inventory can change rapidly, current quantity, condition, traceability, and price should be confirmed before ordering.

What is the price of the DP83902AVLJ?

A numeric DP83902AVLJ unit price is not available in the verified results as of 2026-10-28. DigiKey exposes purchasing, pricing, and availability functions for the part, while the other verified sellers primarily request a quotation. The price tiers on this page therefore contain null values rather than invented numbers. Buyers should request a formal quotation covering quantity breaks, component condition, packaging, traceability, and delivery date.

What is the lead time and stock status of the DP83902AVLJ?

The verified Heisener listing reported 8,484 pieces in stock and an estimated delivery of January 15 through January 20 as of the supplied 2026-10-28 retrieval. However, the listing uses request-for-quotation terms and the part is obsolete, so the historical stock figure should not be treated as guaranteed current inventory. Confirm availability directly with the seller, including lot date, traceability, and whether the offered pieces are new, factory-sealed, or surplus stock.

What are the key specifications of the DP83902AVLJ that engineers should know?

The key verified specifications are a 4.75 V to 5.25 V supply range, approximately 140 mA supply current, a serial interface, a 100-BFQFP package, commercial temperature grade, and tray packaging. The device is an obsolete Texas Instruments serial network interface controller intended for twisted-pair networking. Ethernet data rate, complete pin functions, operating-temperature limits, electrical timing, and compliance declarations are not present in the supplied evidence and require confirmation from the manufacturer datasheet.

Panduan Pilihan

Choose the DP83902AVLJ when repairing or continuing an unchanged legacy design that already depends on its 100-BFQFP footprint, 5 V supply arrangement, and original controller software. Confirm the exact board revision, package orientation, transceiver architecture, operating temperature, and source condition before ordering because the component is obsolete and the verified inventory record may change. Do not choose the SERC816/TR as a drop-in replacement: the available evidence explicitly identifies pinout, internal-biasing, and MII timing differences. Treat it only as a functional redesign candidate after schematic and firmware work. For a new product, select a currently supported Ethernet controller instead of reproducing this obsolete architecture. This recommendation balances the value of preserving proven legacy equipment against the sourcing, thermal, qualification, and long-term availability risks associated with an obsolete 100-pin network controller.

Catatan Desain

Do not treat a functionally similar Ethernet controller as a drop-in substitute. The verified SERC816/TR comparison identifies differences in pinout, internal biasing, and MII timing characteristics. A replacement must be checked against the complete DP83902A pin list, power requirements, transceiver signals, clocking, reset behavior, interrupt handling, and host-side software before any board or firmware change is approved.

Design or service the controller rail for a nominal 5 V supply within the verified 4.75 V to 5.25 V range. The reported 140 mA supply current is the verified baseline, but it should not be treated as the maximum transient demand without the manufacturer timing and load data. Decoupling values, allowable ripple, startup sequencing, and power-consumption limits require confirmation from the original DP83902A datasheet and schematic.

For continued production of an unchanged board, source the exact 100-BFQFP package and verify pin-one orientation against the board footprint. The verified catalog data identifies a 14 mm by 20 mm 100-QFP with gull-wing terminals, but the supplied excerpt does not include a land pattern or complete dimensions. Inspect the original component, assembly documentation, and manufacturer drawing before approving solder paste, stencil, or placement changes.

The controller is specified as commercial grade, and its verified catalog listing supplies a 140 mA operating current. These facts do not establish permissible ambient temperature, junction temperature, or package dissipation. For long-term continuation sourcing, document the original thermal conditions and request the manufacturer datasheet or qualified engineering data. Avoid adding heat-sink assumptions based solely on the 100-QFP package because the actual dissipation and board thermal path are not provided.

Legacy twisted-pair Ethernet interfaces often combine a controller, transceiver, isolation barrier, magnetics, and a host bus. During repair, preserve original component placement, high-speed trace topology, grounding, and isolation clearances unless a complete reference design supports changes. The verified material does not identify signal names or timing values, so the original layout must remain the authority when maintaining an existing DP83902AVLJ design.

The supplied verified data identifies the product as commercial grade but does not extract RoHS, REACH, lead-free, halogen-free, or conflict-minerals declarations. AEC-Q100 is marked not_applicable because the device is a commercial-grade network interface controller rather than an identified automotive-qualified part.
