You searched one part. Parter watches your whole BOM.
All your BOM, at once
Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.
Hear about problems before they hit production
Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.
Qualified replacements in minutes, not days
Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
Frequently asked questions
Yes. The Diodes Incorporated US1M is marked obsolete, so the manufacturer has discontinued it and any remaining supply is limited to distributor stock. The qualified second sources on this page are active parts you can design in today.
The closest qualified second sources for the Diodes Incorporated US1M are the US1M-13-F (Diodes Incorporated) and the US1M-E3/61T (Vishay General Semiconductor - Diodes Division), out of 6 matched alternatives in total. Each is compared against the original on fit, form and function in the table above.
Partly. Some alternatives to the US1M are full fit-, form- and function-compatible drop-ins, while others match on function but differ in package or a key parameter. Check the fit/form/function notes in the table and the datasheet for your application before swapping.
The US1M (Diodes Incorporated) is a part in the Diodes category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
