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 Texas Instruments ISO7240MDW 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 ISO7240MDW are the ISO7740DWR (Texas Instruments) and the ISO6740DWR (Texas Instruments), out of 10 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 ISO7240MDW 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 ISO7240MDW (Texas Instruments) is a part in the Digital Isolators category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
