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: https://www.lcsc.com

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: https://jlcsearch.tscircuit.com

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:

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.

# Sync datasheets for a KiCad project
python3 <skill-path>/scripts/sync_datasheets_lcsc.py <file.kicad_sch>

# Preview what would be downloaded
python3 <skill-path>/scripts/sync_datasheets_lcsc.py <file.kicad_sch> --dry-run

# Retry previously failed downloads
python3 <skill-path>/scripts/sync_datasheets_lcsc.py <file.kicad_sch> --force

# Custom output directory
python3 <skill-path>/scripts/sync_datasheets_lcsc.py <file.kicad_sch> -o ./my-datasheets

# Parallel downloads (3 workers)
python3 <skill-path>/scripts/sync_datasheets_lcsc.py <file.kicad_sch> --parallel 3

# Batch mode — sync from a plain MPN list (no KiCad project required)
python3 <skill-path>/scripts/sync_datasheets_lcsc.py --mpn-list mpns.txt --output ./datasheets

MPN-list batch mode (KH-312) — when you have a list of MPNs but no KiCad project to point at. One MPN per line; blank lines and # comments (full-line and inline) are skipped; generic values are filtered via is_real_mpn() and de-duplicated. Output defaults to ./datasheets/ in the current working directory when --output is omitted.

The script:

Runs the kicad schematic analyzer to extract components, MPNs, and LCSC codes
Accepts any identifier — MPN, LCSC code, or other distributor PNs from KiCad symbol properties
Prefers LCSC code for search (exact match) — falls back to MPN keyword search
Falls back to wmsc.lcsc.com API when jlcsearch has no results for an LCSC code (Cxxxxx)
Downloads from LCSC CDN — direct PDF URLs, no bot protection
Writes manifest.json manifest — same format as DigiKey/Mouser skills
Verifies PDF content — checks MPN, manufacturer, and description keywords
Rate-limited — 0.5s between API calls (configurable with --delay)
Saves progress incrementally — safe to interrupt

Single Datasheet Download

Use fetch_datasheet_lcsc.py for one-off downloads.

# Search by MPN
python3 <skill-path>/scripts/fetch_datasheet_lcsc.py --search "GRM155R71C104KA88D" -o datasheet.pdf

# Search by LCSC code
python3 <skill-path>/scripts/fetch_datasheet_lcsc.py --search "C14663" -o datasheet.pdf

# Direct URL download
python3 <skill-path>/scripts/fetch_datasheet_lcsc.py "https://wmsc.lcsc.com/..." -o datasheet.pdf

# JSON output
python3 <skill-path>/scripts/fetch_datasheet_lcsc.py --search "C14663" --json

The script:

OS-agnostic — uses requests → urllib → playwright fallback chain (no wget/curl)
Validates PDF headers — rejects HTML error pages
Falls back to alternative manufacturer sources when LCSC URL fails
Exit codes: 0 = success, 1 = download failed, 2 = search/API error
Dependencies:
- pip install requests (recommended; urllib fallback works fine for LCSC)
- pip install playwright && playwright install chromium (optional; rarely needed for LCSC)

LCSC Official API (Requires Approval)

Base URL: https://ips.lcsc.com. Requires API key + signature authentication. Contact support@lcsc.com for access. Rarely needed — jlcsearch covers most use cases.

Web Search Fallback

If the jlcsearch API is unavailable, search LCSC by fetching the website directly:

https://www.lcsc.com/search?q=<query>

Cross-Referencing & Missing Equivalents

LCSC part numbers are specific to the LCSC/JLCPCB ecosystem. Use the extra.mpn field to cross-reference on DigiKey/Mouser.

When an MPN has no exact LCSC match:

Search by key parameters (e.g., "100nF 0402 X7R 16V")
Look for pin-compatible alternatives from Chinese manufacturers
Verify specs and footprint match — pad dimensions can vary even within the same package size
As a last resort, mark as "consigned" and source separately

Tips

basic field matters — JLCPCB basic parts have no setup fee; extended parts cost $3 each
Check stock per warehouse (whs-js, whs-zh, whs-hk) — availability varies
moq and order_multiple — many parts require minimum quantities or specific multiples
Datasheet quality varies for Chinese manufacturers — cross-reference MPN on DigiKey for better docs
