Jlcpcb Component Finder

Search the JLCPCB electronic components database (~7M parts) for hardware projects. Use when: (1) Finding components (resistors, capacitors, inductors, ICs, connectors, diodes, transistors, MOSFETs, op-amps, microcontrollers, sensors, LEDs, voltage regulators, audio jacks, etc.), (2) Looking up part numbers, LCSC (C-prefix), or manufacturer part numbers, (3) Finding alternatives/equivalents, (4) Checking stock at JLCPCB/LCSC, (5) Getting specs (package, footprint), (6) Searching SMD or through-hole parts. Keywords: JLCPCB, LCSC, PCB parts, SMT, PCBA, BOM, component sourcing.

File contents

JLCPCB Parts Finder

Search ~7 million electronic components in the local JLCPCB database.

Database

Path: $HOME/.jlcpcb-db/cache.sqlite3 (~5 GB, yaqwsx/jlcparts source-db-v2 schema: table jlc_components)
Override the path with the JLCPCB_DB_PATH env var if needed
If missing, tell the user to run /jlcpcb-component-finder-update-db

Query Script

All queries use: node $HOME/.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 <category> [keyword] [limit]`	Search within a category (category is a NAME substring, matched against category/subcategory)
`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 $HOME/.claude/skills/jlcpcb-component-finder/query.js db-info

# Find audio-related categories
node $HOME/.claude/skills/jlcpcb-component-finder/query.js list-categories "audio"

# Search for 3.5mm audio jacks within the "Audio" category
node $HOME/.claude/skills/jlcpcb-component-finder/query.js search-parts "Audio" "3.5" 10

# Search for CH340 across all categories
node $HOME/.claude/skills/jlcpcb-component-finder/query.js search-all "CH340" 10

# Look up a specific part
node $HOME/.claude/skills/jlcpcb-component-finder/query.js lookup C12084

Workflow

Understand request - What component does the user need?
Find category - Use list-categories [keyword] or search-all for quick discovery
Search parts - Use search-parts with a category name, or search-all for 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-all when you don't know the category
Use list-categories with a keyword to discover category names
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
