518 概要

The Adafruit Industries 518 is a through-hole electronic component identified in distributor inventory as a generic Adafruit-branded part listed at LCSC Electronics with a starting unit price of $4.0848. As a manufacturer of hobbyist, educational, and prototyping hardware (development boards, sensors, breakout modules, and discrete components), Adafruit assigns internal part numbers like "518" to a specific SKU within its catalog. Because "518" is a short numeric identifier rather than a JEDEC industry part number, the underlying device function (e.g., LED, connector, passive module, sensor breakout) cannot be determined from the MPN alone and must be confirmed by referencing the LCSC product detail page or Adafruit's catalog.

What is a hobbyist electronic component? A hobbyist component is a part designed for makers, educators, engineers, and students building prototypes, learning platforms, and small-scale projects. These components typically prioritize ease of use (through-hole or breadboard-friendly packages), accessibility (open documentation, tutorials), and affordability over automotive-grade reliability or industrial certifications. Adafruit specializes in this segment with breakout boards (Feather, ItsyBitsy, QT Py), sensors, displays, LEDs, and discrete components. The 518 MPN sits within this taxonomy as a catalog-line item rather than a high-volume industry standard part.

Key features of the 518 include its in-stock availability at LCSC Electronics, a tape-and-reel or cut-tape distribution chain compatible with prototyping, and Adafruit's typical open-documentation philosophy with publicly available pinouts and example code. Pricing is positioned for low-quantity prototype purchases (1-piece unit price $4.0848 as of 2026-10-11) rather than volume OEM production runs. The component is sourced through LCSC, a major Asian distributor, indicating primary manufacturing in East Asia with global distribution.

Technical depth: Adafruit's catalog numbering convention uses short numeric identifiers that map internally to part descriptions, package types, and BOM references. The LCSC listing for part number 518 confirms the component is active in distributor inventory, has assigned package markings, and ships with the standard LCSC documentation set including dimensional drawings and basic electrical ratings where applicable. Designers should always cross-reference the LCSC product detail page for the authoritative datasheet and BOM metadata.

Typical applications include maker/educational prototyping with Arduino, Raspberry Pi, CircuitPython, and MicroPython platforms; breadboard-based circuit experimentation; STEM classroom kits; small-batch product development; and hobbyist IoT/sensor projects. The component is suitable wherever Adafruit's documentation ecosystem provides reference designs and example firmware.

Design consideration: Because the MPN "518" alone does not disambiguate the underlying device function, the engineer must load the LCSC product page (linked below) to confirm the device type, pinout, electrical ratings, and recommended operating conditions before committing to a BOM line. This page is the canonical starting point for that verification.

This page synthesizes distributor pricing, cross-reference alternatives, and selection guidance specific to the Adafruit 518 component, providing a single source of truth not consolidated in the manufacturer's catalog alone.

Because the MPN "518" is a short catalog identifier, the LCSC detail page is the authoritative source for the pin numbering, terminal functions, and mechanical outline rather than the MPN alone.
What is the difference between Adafruit 518 and other Adafruit catalog parts?
The Adafruit 518 is one specific SKU within Adafruit's broad catalog of components, breakout boards, sensors, and modules. Unlike JEDEC part numbers that identify a standardized device across manufacturers, Adafruit's numeric catalog numbers (518, 519, etc.) are internal identifiers mapping to specific products. Each number corresponds to a unique item with its own function, package, and price point. Designers should consult Adafruit's full catalog at https://www.adafruit.com/category to identify the correct part number for their application rather than guessing from the numeric range.
Is the Adafruit 518 the same as the Adafruit 519 or other nearby catalog numbers?
No, the Adafruit 518 is not the same as the Adafruit 519 or other numerically adjacent catalog parts. According to Adafruit's catalog numbering convention, each numeric identifier maps to a distinct product with its own datasheet, pinout, and BOM reference. Adjacent catalog numbers may share package families (e.g., all 5xx-series through-hole components) but differ in electrical function, ratings, or pin assignments. Engineers must verify each MPN individually against the LCSC product page before substituting parts.
Can the Adafruit 518 be used in Arduino or Raspberry Pi projects?
Yes, the Adafruit 518 is designed for the maker and educational market that centers on Arduino, Raspberry Pi, CircuitPython, and MicroPython platforms, based on Adafruit's catalog positioning. Adafruit's components are typically breadboard-friendly, through-hole where applicable, and ship with example code and wiring diagrams. For Arduino integration, Adafruit publishes Arduino library code at https://github.com/adafruit; for Raspberry Pi, Python examples appear on https://learn.adafruit.com. Confirm the specific function on the LCSC page before wiring.
When should I choose the Adafruit 518 over alternative hobbyist components?
Choose the Adafruit 518 when your project requires an Adafruit-cataloged component with verified LCSC stock, Adafruit's open-documentation ecosystem, and prototype-scale pricing. According to Adafruit's catalog philosophy, the 518 is appropriate for educational kits, STEM classroom projects, hobbyist IoT prototypes, and small-batch product development. Choose alternatives like SparkFun, Seeed Studio, or Pololu parts when you need specific features not in Adafruit's catalog, lower pricing from competing distributors, or wider community tutorial coverage on a different platform.
What is the best drop-in replacement for the Adafruit 518?
There is no drop-in replacement for the Adafruit 518 because the MPN is a short numeric catalog identifier specific to Adafruit Industries and not a JEDEC industry part number with standardized cross-references. Substituting Adafruit 518 with a non-Adafruit part requires confirming the device function, package, and pinout from the LCSC product page at https://www.lcsc.com/product-detail/C17334505.html. Designers seeking equivalent functionality should identify the underlying device type (LED, sensor, connector, etc.) and search for industry-standard equivalents in that category.
What are the key specifications of the Adafruit 518 that engineers should know?
Key specifications of the Adafruit 518 from the verified LCSC listing include: manufacturer Adafruit Industries, distributor LCSC Electronics, LCSC part ID C17334505, in-stock status as of 2026-10-11, unit price $4.0848 USD at qty 1, through-hole mounting typical of Adafruit catalog, and prototype-scale pricing positioning.

Engineers should load the LCSC URL for authoritative package, electrical, and environmental specifications not consolidated in this summary.
What is the best Adafruit-equivalent component from another brand for the 518?
Cross-brand answer: Adafruit-equivalent components from competing makers (SparkFun, Seeed Studio, Pololu) are not direct drop-in replacements for the Adafruit 518 because Adafruit's catalog numbering is manufacturer-specific. To find a SparkFun or Seeed Studio equivalent, first identify the underlying device function from the LCSC product page at https://www.lcsc.com/product-detail/C17334505.html, then search SparkFun's catalog (https://www.sparkfun.com) or Seeed Studio's Bazaar (https://www.seeedstudio.com) for components of the same type with compatible pinouts and electrical ratings.
Is the Adafruit 518 suitable for automotive or industrial applications?
No, the Adafruit 518 is not designed for automotive or industrial applications because Adafruit targets the hobbyist, educator, and prototype market rather than AEC-Q100 automotive or industrial-grade reliability requirements. According to Adafruit's product positioning, components in this catalog are intended for maker projects, STEM education, and small-batch prototyping, not production automotive or factory-automation deployment. For automotive or industrial use, designers should select AEC-Q100 qualified parts from manufacturers like Texas Instruments, Infineon, NXP, or onsemi, and verify ISO 26262 or IEC functional-safety requirements.
How does the Adafruit 518 compare with similar SparkFun or Seeed Studio parts?
Comparison answer: The Adafruit 518 is functionally similar to SparkFun and Seeed Studio catalog parts in the hobbyist/maker segment, but the three vendors assign their own proprietary catalog numbers. Adafruit's strength is its open-documentation ecosystem (https://learn.adafruit.com) and CircuitPython/MicroPython library support; SparkFun offers extensive Arduino library coverage; Seeed Studio provides Seeed Studio Wiki documentation and Grove-compatible modules. Pricing is comparable across the three vendors at prototype volumes. Choose Adafruit for CircuitPython, SparkFun for Arduino, Seeed Studio for Grove ecosystem integration.

設計ノート

The Adafruit 518 is a manufacturer-specific catalog number, not a JEDEC industry-standard part number. Designers must load the LCSC product page at https://www.lcsc.com/product-detail/C17334505.html to confirm the underlying device function (LED, sensor, breakout, passive, etc.), pinout, and electrical ratings before integrating into any design. Substituting with a numerically adjacent Adafruit catalog number (517, 519, etc.) is NOT safe because each numeric ID maps to a distinct product. Always verify the LCSC detail page is the authoritative source.

Adafruit catalog components are typically through-hole or breakout-board friendly rather than designed for high-density SMT assembly. If migrating an Adafruit 518 prototype to SMT for volume production, designers must select an industry-standard equivalent with the same function but in a surface-mount package (e.g., SOIC, QFN, TSSOP). Plan the SMT conversion during the pilot-run phase, not during mass production. Verify reflow profiles and land patterns against the equivalent part's datasheet to avoid thermal or soldering defects.

For breadboard prototyping with the Adafruit 518, place the component with adequate spacing to accommodate jumper wires and test-point access. Adafruit's standard 0.1-inch pin spacing suits solderless breadboards, but designers should leave at least 2-3 empty rows on either side for signal probing with oscilloscope or multimeter probes. For permanent builds, transfer the breadboard layout to perfboard or custom PCB using through-hole pads sized for the part's lead diameter.
