DigiKey Electronics Search

DigiKey's catalog — millions of parts, real-time stock and quantity pricing — one command away.

adom-digikey is the single-vendor DigiKey tool for the Adom ecosystem — one Rust binary, three faces:

• CLI — adom-digikey search | part | health for quick JSON-returning shell use and BOMs.
• Hydrogen app — adom-digikey app opens a searchable UI as a first-class Hydrogen tab.
• Backend service — adom-digikey serve runs the shared proxy (port 8777) that powers the service-digikey container and feeds adom-parts-search.

It replaces the old service-digikey + MCP setup: no MCP server.

adom-wiki pkg install adom-digikey
adom-digikey search "BME280"

Real-time stock, straight to the bench

DigiKey shines when you need it today. Every card shows live stock, qty-1 price and the full break ladder, lead time, RoHS and lifecycle — and DigiKey's deep catalog means the obscure sensor or alt part is usually right there.

Find the exact part, and its alternates

Search a function (buck regulator 1A SOT-23) or a precise MPN. DigiKey's parametric data lets the cards surface the specs that actually drive a decision — Iq, Iout, Vin range, package — so the substitute is one glance away when the first choice is out.

Scriptable from the first keystroke

search returns JSON; part fetches one MPN; health checks the backend's OAuth token. Pipe it into jq, a BOM, or another Claude step.

adom-digikey search "TPS62840DLCR" | jq '.components[0]'
adom-digikey part "296-TPS62840DLCRCT-ND"
adom-digikey health

Install

adom-wiki pkg install adom-digikey

How it works

  any container                          service-digikey
  $ adom-digikey search "BME280" ──POST──▶  adom-digikey serve  (:8777)
  $ adom-digikey app                        DIGIKEY_CLIENT_ID + OAuth
    (Hydrogen webview tab)                  token-refresh + cache
                                                 │
                                                 ▼
                                          api.digikey.com (v4)

The backend manages the DigiKey OAuth handshake and token refresh for you; the CLI auto-detects it (or a local :8777). DigiKey is the go-to alternate when Mouser is out of stock or long-lead — see how adom-parts-search flips the recommendation automatically.

Open source — make it yours, then give it back

This app is open source under the MIT license. Fork it, rewrite it, rename it, bend it to your own workflow — and when you've made it better, send your changes back to the Adom Wiki so the whole community benefits. Every wiki page is a git repo with a package registry on top, so contributing back is first-class — improvements that land here ship to every Adom user who installs the app.

adom-wiki pkg install adom-digikey      # install it
#   …edit the source to taste…
adom-wiki pkg publish             # publish your own fork, or
#   open a pull request against this page so the change lands for everyone

One caveat — the search backend is an Adom service. The actual lookups run against Adom's hosted DigiKey backend (service-digikey), which uses Adom's vendor API credentials and counts against Adom's quota. That hosted backend is an Adom service and is subject to change — rate limits, endpoints, and availability can move at any time. Everything client-side (the CLI, the webview, the rendering and recommendation logic) is yours to fork and republish; the cloud API quota is not.
