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 Analog Devices ADG508AKR 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 Analog Devices ADG508AKR are the ADG508AKRZ (Analog Devices Inc.) and the DG508BEY-T1-E3 (Vishay Siliconix), out of 7 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 ADG508AKR 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 ADG508AKR (Analog Devices) is a part in the Interface category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
