What It Does

Search JLCPCB's entire in-stock catalog of electronic components by electrical specifications. Instead of browsing pages of parts, describe what you need and get back matching components with stock counts, unit prices, and full specs.

Supported component types:

Type	Search Filters
🔲 Resistors	Resistance, package, tolerance, power
🔵 Capacitors	Capacitance, package, voltage, tolerance
🟡 Inductors	Inductance, package, current, tolerance
🔴 LEDs	Color, package, voltage, current
⚡ MOSFETs	Package, voltage, current, channel type
🧠 ICs	Package, manufacturer, category

Use Cases

BOM generation — automate finding the right parts for your circuit design
Design validation — verify that components exist in JLCPCB stock before finalizing
Price comparison — find the cheapest in-stock part matching your specs
Alt-part discovery — find substitute components when your primary choice is out of stock

Input

{
  "component_type": "resistor",
  "resistance": "10k",
  "package": "0603",
  "tolerance": "1%",
  "max_results": 50
}

Parameter	Type	Required	Description
`component_type`	string	✅	One of: `resistor`, `capacitor`, `inductor`, `led`, `mosfet`, `ic`
`resistance`	string	❌	Resistance value (e.g. `1k`, `4.7k`, `10k`). Resistors only.
`capacitance`	string	❌	Capacitance value (e.g. `100n`, `10u`, `22p`). Capacitors only.
`inductance`	string	❌	Inductance value (e.g. `10uH`, `4.7uH`). Inductors only.
`package`	string	❌	Package size (e.g. `0402`, `0603`, `0805`)
`tolerance`	string	❌	Tolerance (e.g. `1%`, `5%`, `10%`)
`voltage`	string	❌	Voltage rating (e.g. `10V`, `50V`, `100V`)
`max_results`	integer	❌	Max parts to return (1–500, default 50)

Output

Each result includes:

{
  "lcsc": 123456,

  "package": "0603",
  "stock": 50000,
  "price1": 0.0009,
  "resistance": 10000,
  "tolerance": "1%"
}

Field	Description
`lcsc`	Unique LCSC/JLCPCB part number
`mfr`	Manufacturer part number
`package`	Component footprint (0402, 0603, etc.)
`stock`	Current in-stock quantity
`price1`	Unit price in USD
Component-specific fields	`resistance`, `capacitance`, `inductance`, `voltage`, `tolerance`, `color`
