datasheet-first · open · structured
The datasheet search that's actually structured.
Archives dump PDFs with no structure. Distributors have the structure but lock it to their buy-flow and only list what's in stock. We do both — the broad open archive, with real parametric filters, clean specs and honest provenance on top.
Why nobody else has this — the gap in the market
Datasheet archives
alldatasheet · datasheetarchive
- Broad corpus — millions of PDFs, obsolete parts kept
- No parameters, no taxonomy, no dedup
- LM358 scattered across 24 rows / 8 vendors
Distributor catalogs
digikey · octopart
- Rich structure — parametric filters, facets
- Only what's in stock & for sale
- Datasheet buried under the buy-flow
datasheets.pro
◆ the combination
- Archive breadth — 2.2M datasheets, obsolete & active
- Distributor structure — parameters, facets, clean taxonomy
- Datasheet-first & deduped — one canonical part, PDF up front
See what you get — for every part not just a link to a PDF

Every spec, with provenance
Each value shows its source and date — feed or datasheet extract. No anonymous numbers.
The datasheet, inline
PDF text rendered as indexable HTML plus a page viewer — the site actually shows the datasheet.
Decoded & deduped
Part number broken down token by token, one canonical entry instead of 24 vendor rows.

Data you can trust — and where it fails, we say so
Deduplicated
One canonical entry per part, not the same device scattered across every second-source vendor.
Provenance on every spec
Each parameter carries its source and the date it was parsed — feed or datasheet. Verifiable, not anonymous.
Honest about gaps
No public datasheet? We label a confidence tier and never invent specs. How it's built →
Questions
Is datasheets.pro free to use?+
Yes — search, parametric filters, part pages and datasheets are open, with no login wall in front of the specs.
Where does the data come from?+
A corpus of 2.2M unique datasheets covering 16M part numbers, cross-referenced with distributor and manufacturer parametric feeds, plus specifications extracted directly from the datasheet PDFs. Every spec shows its source.
Can I find obsolete and hard-to-find parts?+
That's the point. We keep obsolete and second-source parts, and for parts with no public datasheet at all we assemble an honest, confidence-tiered page from whatever fragments exist — instead of a dead end.
How is this different from alldatasheet or Octopart?+
Archives have the breadth but no structure — no parameters, no dedup. Distributors have the structure but only for parts in stock, behind their buy-flow. datasheets.pro is both: the broad open archive with real parametric structure on top.
Do you host the PDFs?+
We link to manufacturer-hosted datasheets where possible and index the extracted text so it's searchable. Rights holders can request removal via our takedown policy.
