onsemi discontinued parts & EOL cross-reference

This page indexes the onsemi discontinuations we have verified from the manufacturer's own lifecycle and discontinuance notices: 215 records across 1 dataset, each with its notice, its last-time-buy and last-shipment dates where published, and — where the manufacturer printed one — the recommended replacement.

How to check whether your onsemi part is discontinued

  1. Work from the exact ordering part number on your BOM — discontinuation is published at part-number level, so the same device in a different package or speed grade can have a different status and a different replacement.
  2. Find the dataset above that covers your part family or notice, and open the free sample records on its page or guide.
  3. Note the notice's last-time-buy date. If it has passed, the part is no longer orderable from the manufacturer — remaining stock only.
  4. Check the printed replacement's package and key specifications against your board. Manufacturer-recommended replacements are not always drop-in compatible.

Frequently asked questions

How can I check whether a onsemi part is discontinued?

Check the ordering part number against the manufacturer's published lifecycle / discontinuance notices. This page indexes the 215 onsemi 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 onsemi-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.
