check_design_fit is what changes the workflow: input voltage, output current, ambient temperature and switching frequency are compared with the datasheet's absolute maximum and recommended ratings, and each parameter returns a verdict with a margin rather than a paragraph. Extraction is asynchronous and visible — prefetch a BOM's worth of parts, then poll each one's step — which is why a read against a cold part may answer that it is still extracting. Where no datasheet exists at all, one can be uploaded, re-hashed and validated against the part number before it is trusted.
A parts and datasheet service for electronics: multi-provider search, extracted datasheets, comparison, alternatives and a design-fit check.
- Component search that queries the configured providers in parallel and merges results by manufacturer part number with indicative pricing and stock, plus full detail for one part by MPN or LCSC number.
- Datasheets read by named section or by query, starting from a summary that lists the sections available, and semantic search across every extracted datasheet.
- Background extraction for up to 20 parts at a time, with a status check reporting each part's current step and elapsed seconds.
- Two to five parts compared side by side with merged provider data, structured parameters, package and datasheet status.
- A design-fit check that measures your supply and output voltages, current, ambient temperature and switching frequency against absolute maximum ratings and recommended operating conditions, returning PASS, FAIL or WARNING per parameter with margins.
- Alternatives ranked by how closely specs, package and category match the reference part, each with a match score and notes.
- Datasheet upload by signed URL for parts with no source, re-hashed for integrity and validated against the MPN on the first page.
- Images from a datasheet — graphs, package drawings, pin diagrams and schematics — read by vision from an image key.
Nothing — no account, no key. Which distributors are searched depends on the providers configured on the server.
