How can I check whether a Molex part is discontinued?
Check the ordering part number against the manufacturer's published lifecycle / discontinuance notices. This page indexes the 2,194 Molex records we have verified from those notices, with the replacement the manufacturer printed for each part.
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 — exactly when a verified replacement cross-reference matters most.
Are manufacturer-recommended replacements drop-in compatible?
Not always. Some notices warn explicitly that the recommended replacement is not pin or voltage compatible and requires a board redesign. Always verify package and key specs before committing a design or a purchase order.
Where does this data come from?
Every record is extracted from a Molex-authored document — 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.
