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 Texas Instruments LM2575S-5.0 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 Texas Instruments LM2575S-5.0 are the LM2575S-5.0/NOPB (Texas Instruments) and the LM2575-5.0WU (Microchip Technology), out of 6 matched alternatives in total. Each is compared against the original on fit, form and function in the table above.
Not always. The alternatives to the LM2575S-5.0 are matched on function but can differ in package, pinout or a key parameter, so review the fit/form/function notes in the table and the datasheet before designing one in.
The LM2575S-5.0 (Texas Instruments) is a part in the Power Management (PMIC) category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
