jlcpcb-component-finder
Search the JLCPCB electronic components database (~7 million parts) for hardware/electronics projects. Use when the user needs to: (1) Find electronic components (resistors, capacitors, inductors, ICs, connectors, diodes, transistors, MOSFETs, op-amps, microcontrollers, sensors, LEDs, etc.), (2) Look up specific part numbers, LCSC numbers (C-prefix), or manufacturer part numbers, (3) Find alternatives or equivalents for components, (4) Check component availability and stock at JLCPCB/LCSC, (5) Get component specifications (package type, footprint, description), (6) Search for parts for PCB assembly (PCBA) projects, (7) Find SMD or through-hole components, (8) Look up voltage regulators (LDO, linear, switching), audio jacks, connectors, or any other electronic parts. Keywords: JLCPCB, LCSC, electronic components, PCB parts, SMT assembly, BOM, bill of materials, component sourcing.

JLCPCB Parts Finder
Search ~7 million electronic components in the local JLCPCB database.
Database
- Path:
~/.jlcpcb-db/cache.sqlite3(~11 GB) - If missing, tell the user to run
/jlcpcb-component-finder-update-db
Query Script
All queries use: node ~/.claude/skills/jlcpcb-component-finder/query.js <command>
Commands
| Command | Usage | Description |
|---|---|---|
db-info |
node query.js db-info |
Show DB stats (total parts, categories, stock count, DB date) |
list-categories |
node query.js list-categories [keyword] |
List categories, optionally filtered by keyword |
search-parts |
node query.js search-parts <cat_id> [keyword] [limit] |
Search within a specific category |
search-all |
node query.js search-all <keyword> [limit] |
Search across ALL categories by keyword |
lookup |
node query.js lookup <lcsc_number> |
Look up a specific part by LCSC number (e.g. C12084) |
Examples
# Check database status
node ~/.claude/skills/jlcpcb-component-finder/query.js db-info
# Find audio-related categories
node ~/.claude/skills/jlcpcb-component-finder/query.js list-categories "audio"
# Search for 3.5mm audio jacks in category 208
node ~/.claude/skills/jlcpcb-component-finder/query.js search-parts 208 "3.5" 10
# Search for CH340 across all categories
node ~/.claude/skills/jlcpcb-component-finder/query.js search-all "CH340" 10
# Look up a specific part
node ~/.claude/skills/jlcpcb-component-finder/query.js lookup C12084Workflow
- Understand request - What component does the user need?
- Find category - Use
list-categories [keyword]orsearch-allfor quick discovery - Search parts - Use
search-partswith category ID, orsearch-allfor cross-category - Present results with LCSC number, manufacturer, description, package, stock, price, and URL
Output Fields
Each result includes:
- LCSC number (C-prefix, e.g. C12084)
- Manufacturer and description
- Package type (e.g. SOP-8, 0805)
- Stock availability (sorted highest first)
- Basic/Preferred tags - Basic parts have lower assembly fees at JLCPCB
- Price tiers (quantity breaks)
- Datasheet URL (when available)
- Detail page URL:
https://jlcpcb.com/partdetail/C{number}
Tips
- Basic parts have the lowest JLCPCB assembly fee - prefer these when possible
- Preferred parts are commonly used and well-stocked
- Start with broader keywords if specific searches return no results
- Use
search-allwhen you don't know the category - Use
list-categorieswith a keyword to narrow down category IDs - Limit initial searches to 10-20 results to avoid overwhelming output
- Results are sorted by stock (descending) - highest stock = most available
- Always include the detail page URL in recommendations
