How do I check whether a specific C&K Switches part is in this dataset?
Open the free sample records on the dataset page first — they are copied verbatim from the paid file. The full file lists every record with its source notice, so you can confirm coverage of your exact part number before relying on the cross-reference.
What does last time buy (LTB) mean?
The last date the manufacturer accepts orders for a discontinued part. After it passes, the part is only available from remaining distributor stock or the secondary market — which is exactly when a verified replacement cross-reference matters most.
Are the recommended replacements drop-in compatible?
Not necessarily. Manufacturers' own notices sometimes warn that a recommended replacement is not pin or voltage compatible and requires a board redesign. Where the source notice prints such a warning, it is carried in the dataset — always check the replacement's package and key specs against your design.
Where does this data come from?
Every record is extracted from a C&K Switches document — the manufacturer's own lifecycle, discontinuation, PCN/PDN notices and the affected-part lists they publish — downloaded from the manufacturer's own channels. No part number, date or replacement is inferred; if the manufacturer did not print it, it is not in the file.
