|---|---|---|---|---|
| FFF Compatibility | Housed in the identical 8-SOIC package (3.90 mm width) with a completely matching pinout assignment.Identical surface-mount SOIC-8 footprint, body dimensions, and height profiles.Meets or exceeds all electrical parameters, providing a wider operating voltage range (1.8V–5.5V) and faster maximum SPI clock speed (10 MHz). | Matches the original 8-SOIC pinout configuration exactly.Housed in the identical SOIC-8 150-mil package size.Matches the supply voltage range (2.5V to 5.5V closely encompasses the original 2.7V to 5.5V) and exceeds the original clock frequency. | ||
 AI Summary | AT25010N-10SI-2.7 by Microchip Technology: EEPROM Memory IC 1Kbit SPI 3 MHz 8-SOIC. | This is the official recommended direct replacement from Microchip. It offers complete hardware and pinout compatibility while widening the supply voltage range down to 1.8V and boosting the clock speed to 10 MHz. This active, RoHS-compliant device is an ideal, risk-free upgrade for obsolete designs.
| A sibling variant of the 25AA010A, this version operates down to 2.5V and serves as a highly reliable drop-in replacement. It provides the same 10 MHz performance and physical footprint in an active, long-lived product family.

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 Microchip Technology AT25010N-10SI-2.7 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 Microchip Technology AT25010N-10SI-2.7 are the 25AA010A-I/SN (Microchip Technology) and the 25LC010A-I/SN (Microchip Technology), out of 5 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 AT25010N-10SI-2.7 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.
