|---|---|---|---|---|
| FFF Compatibility | The pinout (NC, A1, A2, GND, SDA, SCL, WP, VCC) is identical, and the 8-SOIJ package fits the 8-lead EIAJ SOIC 5.28mm footprint exactly.The 8-SOIJ package is physically interchangeable with the original 8-SOIC 208-mil EIAJ package (8S2).This device matches the 1Mbit capacity, 1 MHz operating frequency, 128K x 8 organization, and covers the full original voltage range. | Pins match the original 1-to-1: Pin 1 is NC, Pin 2 is A1, Pin 3 is A2, etc. Suffix 'X' denotes the 8-pin EIAJ SOIC footprint.The CASE 751BE SOIC-8 (EIAJ) package shares the same physical dimensions and pad layout as the original 8S2 package.Operates as a 1Mbit I2C EEPROM at 1 MHz, fully meeting the original electrical specifications. | ||
 AI Summary | AT24C1024BW-SH25-T by Microchip Technology: EEPROM Memory IC 1Mbit I2C 1 MHz 550 ns 8-SOIC. | This is the direct modern successor recommended by Microchip Technology. It provides identical electrical performance and matching pinout in an active, long-term supported product line.
| The CAT24M01XI-T2 from onsemi is an excellent cross-manufacturer drop-in replacement that matches every critical dimension, pin assignment, and speed rating of the obsolete original part.

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 AT24C1024BW-SH25-T 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 AT24C1024BW-SH25-T are the AT24CM01-SHM-T (Microchip Technology) and the CAT24M01XI-T2 (onsemi), 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 AT24C1024BW-SH25-T 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.
