Discontinued electronic components and their manufacturer-suggested replacements, with last-time-buy and last-ship dates where published. Covers EOL notices from TI, NXP, Renesas, Infineon, onsemi, ST, Microchip, Cirrus Logic and commonly sought legacy parts.

Provenance — what every record carries

Every record carries source (the URL the value was read from) and source_quote (a verbatim quote from that page stating it). A value you cannot check against its page is indistinguishable from an invented one; these can all be checked. Each record is also individually addressable on the canonical site at its url.

Licence position

Fair use (factual product discontinuation data aggregated from manufacturer notices)

Facts are not copyrightable; what this dataset takes from each source is a fact plus a short attributed quote linking back to the page that states it.
