About

What chip.parts does

Give chip.parts a list of part numbers or a BOM spreadsheet. It hands back a standardized technical description, current distributor pricing and stock, a matching datasheet, and a moisture sensitivity rating for every part — looked up fresh for the parts you actually have, not browsed from a static catalog that goes stale.

Four services

One part list, four lookups

Run any or all of these against the same MPN list. Each is a self-contained lookup — you don't need the other three to get an answer from one.

01 / Descriptions

Enrich descriptions

A standardized technical description for every part — component type, key electrical parameters, package, and manufacturer — in the same row order you submitted.

Learn more →

02 / Prices

Find prices & stock

Current pricing and stock levels across DigiKey, Mouser, and other distributors, checked in a single batch instead of one part at a time.

Learn more →

03 / Datasheets

Find datasheets

The manufacturer datasheet PDF for each part number, checked against the part before it's returned, ready to download one at a time or as a batch.

04 / MSL

Find MSL

Moisture sensitivity level ratings under IPC/JEDEC J-STD-020, with a source link for each rating so it's checkable, not just asserted.

How it works

Search, standardize, cache, export

Every lookup on chip.parts follows the same flow, whether you're pulling one field or all four.

  1. 1

    Bring your list

    Paste your MPNs, or upload a BOM spreadsheet as it came out of your design tool — no reformatting required.

  2. 2

    Search open sources

    chip.parts searches open technical and distributor sources for each part number, matching manufacturer, package, and part variant.

  3. 3

    Extract & standardize

    Matches get pulled into one consistent record per part — a description, a price and stock line, a datasheet link, an MSL rating — instead of a pile of raw listings for you to sort through.

  4. 4

    Cache & export

    Every result is saved, so a repeat lookup for a part you've already searched comes back instantly instead of searching again. Results export to Excel in your original row order, new or cached.

Why repeat lookups are free

Built for the parts you use most

Caching isn't just a speed trick — it means chip.parts gets more useful for your BOMs the more you use it.

  1. 1

    Your own component library

    Every part chip.parts resolves adds to your workspace, so the parts you reuse across projects need less and less outside searching over time.

  2. 2

    Datasheets that stick around

    A downloaded PDF stays available in your workspace even if a manufacturer later pulls it from their own site.

  3. 3

    Come back to old results

    Processed files stay downloadable after the fact — hand a result to a colleague, or re-check it later, without rerunning the lookup.
