| FFF Compatibility | The pinout (Pins 1-3: Address Inputs, Pin 4: GND, Pin 5: SDA, Pin 6: SCL, Pin 7: WP, Pin 8: VCC) and the 8-SOIC footprint are identical.Both use the standard JEDEC SOIC-8 package with a body width of 0.154 inches (3.90 mm).The electrical and memory parameters are fully backwards-compatible, with improved speed (1 MHz) and wider voltage range (1.7V to 5.5V). | The 8-SOIC package pinout matches the original exactly pin-for-pin.Maintains the standard 0.154 inch (3.90 mm) body width 8-SOIC dimension.Offers a drop-in functional equivalent with 32Kbit memory organized as 4K x 8, with a faster clock and wider voltage support. | ||
 AI Summary | AT24C32AN-10SU-2.7 by Microchip Technology: EEPROM Memory IC 32Kbit I2C 400 kHz 900 ns 8-SOIC. | The AT24C32D-SSHM-T is the direct manufacturer-recommended modern upgrade for the obsolete AT24C32AN. It offers backwards-compatible operation in the same physical footprint while expanding the operating voltage range and frequency capability.
| The CAT24C32WI-GT3 is a direct second-source alternative from onsemi. It is fully pin-compatible and functionally equivalent, serving as a reliable drop-in replacement without any board layout modifications.

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 AT24C32AN-10SU-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 AT24C32AN-10SU-2.7 are the AT24C32D-SSHM-T (Microchip Technology) and the CAT24C32WI-GT3 (onsemi), out of 3 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 AT24C32AN-10SU-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.
