Lcsc

name lcsc description Search LCSC Electronics for electronic components — find parts by LCSC number (Cxxxxx) or MPN, check stock/pricing, download datasheets, analyze specifications. Sister company to JLCPCB, same parts library. Sync and maintain a local datasheets directory for a KiCad project, or use batch MPN-list seeding (--mpn-list) for bulk workflows without a project. No API key needed — uses the free jlcsearch community API. Use this skill when the user mentions LCSC, JLCPCB parts library, JLCPCB assembly parts, production sourcing, Cxxxxx part numbers, needs to find LCSC equivalents for parts, is preparing a BOM for JLCPCB assembly, or wants to download datasheets and LCSC is available. For package cross-reference tables and BOM workflow, see the bom skill. LCSC Electronics — Component Search, Datasheets & Ordering Related Skills Skill Purpose kicad Schematic analysis — extracts MPNs for part lookup bom BOM management — orchestrates sourcing across distributors jlcpcb PCB assembly — shares the same parts library spice Uses LCSC parametric data for behavioral SPICE models (no auth needed) LCSC is JLCPCB's sister company — they share the same parts library and Cxxxxx part numbers. Use LCSC for production sourcing (assembled boards from JLCPCB/PCBWay). DigiKey/Mouser are for prototyping. For BOM management and export workflows, see bom . Key Differences from DigiKey/Mouser No API key needed — jlcsearch community API is free and open Lower prices — especially for passives and Chinese-manufactured ICs JLCPCB integration — same LCSC part numbers used in JLCPCB assembly BOMs Direct PDF downloads — LCSC's CDN (wmsc.lcsc.com) serves datasheets without bot protection Low MOQ — many parts available in quantities as low as 1 Warehouses — Shenzhen (JS), Zhuhai (ZH), Hong Kong (HK) Website : LCSC Part Numbers Format: Cxxxxx (e.g., C14663 ). This is the universal identifier across both LCSC and JLCPCB. Use it for: Direct ordering on LCSC BOM matching in JLCPCB assembly (see jlcpcb skill) Cross-referencing between platforms jlcsearch API Reference The jlcsearch community API is the recommended way to search LCSC. No authentication required. Base URL: General Search GET /api/search?q=<query>&limit=20&full=true Parameters: q — search query (matches MPN, LCSC code, or description keywords) package — optional footprint filter (e.g., 0402 ) limit — max results (default 100) full — set to true to include all fields (datasheet URL, specs, stock per warehouse) Category-Specific Search GET /resistors/list.json?search=10k+0402 GET /capacitors/list.json?search=100nF+0402 GET /microcontrollers/list.json?search=STM32 GET /voltage_regulators/list.json?search=3.3V Response Format Results are returned as {"components": [...]} . With full=true , each component has: { "lcsc" : 14663 , "mfr" : "GRM155R71C104KA88D" , "package" : "0402" , "description" : "" , "datasheet" : "..." , "stock" : 2751535 , "price" : [ { "qFrom" : 1 , "qTo" : 9 , "price" : 0.0069 } , ... ] , "basic" : 0 , "extra" : { "number" : "C71629" , "mpn" : "GRM155R71C104KA88D" , "manufacturer" : { "id" : 4 , "name" : "Murata Electronics" } , "package" : "0402" , "description" : "16V 100nF X7R ±10% 0402 ..." , "quantity" : 2751535 , "whs-js" : 1234567 , "whs-zh" : 567890 , "whs-hk" : 0 , "moq" : 100 , "order_multiple" : 100 , "packaging" : "Tape & Reel (TR)" , "packaging_num" : 10000 , "datasheet" : { "pdf" : "" } , "images" : [ { "96x96" : "..." , "224x224" : "..." , "900x900" : "..." } ] , "rohs" : true , "url" : "..." , "attributes" : { "Capacitance" : "100nF" , "Voltage Rated" : "16V" , "Temperature Coefficient" : "X7R" , "Tolerance" : "±10%" } , "prices" : [ { "min_qty" : 100 , "max_qty" : 499 , "currency" : "USD" , "price" : 0.0048 } , ... ] } } Key fields: lcsc — numeric LCSC ID (without "C" prefix) extra.number — full LCSC code with prefix (e.g., C71629 ) extra.mpn — manufacturer part number extra.manufacturer.name — manufacturer extra.datasheet.pdf — direct PDF URL (wmsc.lcsc.com CDN, downloads without auth) extra.attributes — parametric specs (capacitance, voltage, etc.) extra.quantity — total stock across all warehouses extra.whs-js , extra.whs-zh , extra.whs-hk — stock per warehouse basic — 1 if JLCPCB basic part (no setup fee), 0 if extended extra.moq — minimum order quantity extra.order_multiple — must order in multiples of this extra.rohs — RoHS compliance (boolean) Rate Limits The jlcsearch API is community-run with no documented rate limits, but be respectful — use delays of 0.5s between calls. Datasheet Download & Sync LCSC's CDN serves datasheet PDFs directly — no bot protection, no special headers needed. This makes LCSC a reliable datasheet source alongside DigiKey. Datasheet Directory Sync Use sync_datasheets_lcsc.py to maintain a datasheets/ directory alongside a KiCad project. Same workflow and manifest.json format as the DigiKey and Mouser skills. No API key required.
