SL383 Overview
In the broader electronics ecosystem, packaging suffix codes are part numbers appended to base MPNs to specify delivery format. Common codes include SL383 for Tape & Reel, -TU for tube, and bulk packaging indicators. These suffixes follow JEDEC and IPC packaging standards and are essential for SMT line integration, as they determine carrier tape pocket dimensions, orientation, and reel packaging specifications.
Key features of SL383-coded parts include: full compliance with EIA-481 Tape & Reel standards, integration with pick-and-place equipment, moisture sensitivity level (MSL) handling requirements per JEDEC J-STD-033, and compatibility with automated solder reflow processes. The code appears in Atmel/Microchip AT28C, AT45DB, ATmega, and ATtiny product families, each requiring identical handling protocols despite differing internal silicon.
The SL383 suffix carries no electrical specification - all electrical parameters derive from the parent base MPN. Engineers specifying SL383 must first identify the base part (e.g., AT28C64B-15JU SL383, AT45DB081D-SSU-2.5 SL383, ATmega168PA-MU SL383) and then confirm the packaging form. This two-step identification is critical because each parent MPN belongs to a different functional category.
Typical applications for SL383-packaged parts span any volume SMT assembly environment - consumer electronics, industrial controllers, automotive modules, and IoT devices. Since SL383 is a packaging suffix rather than a functional IC, the application domain is determined entirely by the parent part number chosen.
When designing with SL383-coded parts, always verify MSL handling procedures, confirm reel quantity matches your production lot size, and inspect for any handling damage before reflow. Reels must be stored in dry-packs and used within their floor-life ratings to prevent moisture-induced defects during PCB assembly.

High-Volume SMT Production Line
The SL383 packaging suffix is purpose-built for high-volume surface-mount assembly lines where pick-and-place automation is the primary throughput driver. SL383-coded parts ship on factory-finished reels that comply with EIA-481 carrier tape standards, integrating directly with Yamaha, Siemens, Panasonic, Juki, and Mycronic pick-and-place machines without modification. Unlike tray or tube packaging, SL383 Tape & Reel allows continuous production without manual reloading, dramatically increasing line uptime. Carrier tape pocket dimensions, component orientation, and reel leader/trailer lengths are all standardized to support vision-guided placement systems and feeder compatibility across the SMT equipment ecosystem.
Recommended
Consumer Electronics Manufacturing
Consumer electronics OEMs producing smartphones, wearables, smart home devices, and home appliances rely on SL383 Tape & Reel packaging for cost-effective volume assembly. SL383-coded Atmel/Microchip parts (EEPROMs, Flash memories, and AVR microcontrollers) are integrated into PCBs during reflow soldering, with the Tape & Reel format enabling rapid feeder loading and minimal operator intervention. The standardized EIA-481 carrier tape ensures consistent component placement accuracy, while the SL383 reel packaging reduces per-unit handling cost compared to tray alternatives. This makes SL383-coded parts the preferred choice when production volumes exceed 5,000 units per month.

Industrial Control Module Assembly
Industrial control modules, PLCs, motor controllers, and human-machine interfaces (HMIs) require robust, traceable component sourcing for long-lifecycle products. SL383-packaged Atmel/Microchip parts support industrial-grade assembly by providing factory-traceable reels with lot codes, date codes, and MSL ratings printed on the reel label. Industrial customers benefit from SL383's compatibility with IPC-A-610 acceptance criteria and JEDEC J-STD-033 moisture handling standards. The parent MPN electrical specifications span extended temperature grades, and SL383 ensures those parts are delivered in a format suitable for both contract manufacturers and OEM in-house production lines operating under ISO 9001 quality systems.
Recommended
Automotive Electronics Module Production
Automotive Tier I suppliers producing ECUs, sensor modules, infotainment head units, and ADAS controllers use SL383-coded parts where the parent MPN is AEC-Q100 qualified. The SL383 Tape & Reel format supports the high-volume, fully-automated SMT lines characteristic of automotive electronics manufacturing, where AEC-Q100 traceability and PPAP documentation are mandatory. SL383 reels carry lot codes that integrate with automotive traceability databases, and the EIA-481-compliant format works with vision-guided placement machines to achieve the placement accuracy required for fine-pitch QFN and SOIC packages used in modern automotive electronics. AEC-Q100 qualification status applies to the parent MPN, not the SL383 suffix.
Recommended
IoT and Wireless Sensor Node Assembly
IoT device OEMs building wireless sensor nodes, smart meters, and connected home products rely on SL383-coded Atmel/Microchip parts for the compact Flash memories and low-power microcontrollers central to their designs. The parent MPNs under SL383 include AT45DB DataFlash (for data logging) and ATtiny/ATmega microcontrollers (for sensor processing and wireless protocol handling). SL383 Tape & Reel packaging supports high-mix, high-volume IoT production where thousands of identical boards are assembled per shift. The carrier tape's ESD-protective shielding and moisture-barrier packaging help maintain the reliability required for IoT products deployed in uncontrolled environmental conditions.
Recommended
Medical Device PCB Manufacturing
Medical device OEMs producing patient monitors, diagnostic equipment, infusion pumps, and portable medical devices use SL356-coded Atmel/Microchip parts in their SMT assembly lines for traceability and reliability. The SL383 packaging format provides factory-traceable lot codes essential for FDA 21 CFR Part 820 quality records and ISO 13485 medical device QMS audits. Medical device production volumes are typically lower than consumer electronics, but SL383 reels can be partial-used and resealed under dry-pack protocols per JEDEC J-STD-033, supporting both small and large medical device production runs. Parent MPN selection must follow IEC 60601-1 risk management requirements.

Key Differentiators
- Multi-family coverage from single suffix code (vs TI -TR or Infineon -REEL7 suffixes)
- EIA-481 carrier tape standard compliance (vs Non-standard carrier tape packaging from smaller vendors)
- Factory-traceable lot and MSL labeling (vs Generic Tape & Reel from unbranded sources)
Design Notes
SL383 is a packaging code, not a functional IC. Engineers who search for 'SL383 datasheet' will not find a standalone datasheet because the SL383 suffix carries no electrical specification. Always identify the parent base MPN (e.g., AT28C64B-15JU, AT45DB081D-SSU-2.5, ATmega168PA-MU) and download THAT part's datasheet. Confusing the suffix with a product line is the single most common pitfall when working with Atmel/Microchip packaging codes.
When ordering SL383-packaged parts for SMT production, verify that the carrier tape width matches your pick-and-place feeders. Common carrier tape widths for Atmel/Microchip SL383 parts are 8mm (for SOIC and small QFN), 12mm (for medium QFN and PLCC), and 16mm (for larger PLCC packages). Using the wrong feeder width will cause placement errors or feeder jams. Confirm with your contract manufacturer before placing the order if feeder compatibility is uncertain.
SL383-packaged parts follow standard moisture sensitivity handling per JEDEC J-STD-033. Once the reel vacuum-sealed bag is opened, MSL 2 parts have a 1-year floor life, MSL 2A parts have a 4-week floor life, and MSL 3 parts have a 168-hour floor life. If your production rate is slower than the floor-life rating, you must bake the parts per JEDEC J-STD-033 before reflow to avoid 'popcorn' defects during solder reflow.
When designing PCB land patterns for SL383-packaged parts, use the parent MPN's land pattern from its datasheet, not a generic Tape & Reel pattern. The land pattern is determined by the JEDEC package (SOIC, QFN, PLCC) and is independent of the SL383 packaging form. For example, a 32-PLCC AT28C64B-15JU SL383 uses the standard JEDEC MS-018 land pattern for 32-PLCC sockets or direct PCB mounting.
Compliance Information
SL383 packaging code itself is RoHS compliant and lead-free per parent MPN standards. AEC-Q100 qualification depends on the parent base MPN, not the SL383 suffix. Halogen-free status varies by parent MPN - verify with the specific parent MPN datasheet.
