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 onsemi BAV99LT1 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 onsemi BAV99LT1 are the BAV99LT1G (onsemi) and the SBAV99LT1G (onsemi), out of 5 matched alternatives in total. Each is compared against the original on fit, form and function in the table above.
Yes. The leading alternatives to the BAV99LT1 are fit-, form- and function-compatible — the same package and pinout with matching key electrical specifications — so they drop in without PCB changes. Always confirm the parameters critical to your design against the alternative's datasheet before committing.
