 AI Summary | DS1230Y-100 by Analog Devices: NVSRAM (Non-Volatile SRAM) Memory IC 256Kbit Parallel 100 ns 28-EDIP. | This is the direct lead-free (RoHS compliant) equivalent of the original obsolete part. It offers identical electrical parameters, 100 ns access time, and a 10% supply voltage tolerance, ensuring zero-risk drop-in replacement.
| This is the active, faster-speed variant of the same family. It features a 70 ns access time that easily backward-matches the original 100 ns timing requirement, and serves as the primary manufacturer recommendation since the 100 ns grade is no longer actively produced.

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 DS1230Y-100 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 DS1230Y-100 are the DS1230Y-100+ (Analog Devices Inc./Maxim Integrated) and the DS1230Y-70+ (Analog Devices Inc./Maxim Integrated), out of 4 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 DS1230Y-100 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 DS1230Y-100 (Analog Devices) is a part in the Memory category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
