|---|---|---|---|---|
| FFF Compatibility | Features the exact same JEDEC-standard 8-pin TDFN (2x3mm) footprint and pinout assignments.Matches the physical dimensions, 2x3mm footprint, and 0.80mm height limit.Meets or exceeds all performance specs, including temperature range (-40°C to 125°C), accuracy, and I2C/SMBus protocol. | Features identical pin configurations and matching 8-pin 2x3mm land patterns.Shares the same physical size, surface-mount styling, and package outlines.The supply voltage range is 2.7V to 3.6V, which is narrower than the original 2.3V to 3.6V limit. | ||
 AI Summary | STTS2002B2DN3F by STMicroelectronics: Temp Monitoring System (Sensor) -40°C ~ 125°C Internal Sensor I2C/SMBus Output 8-TDFN (2x3). | The MCP98244T-BE/MNYAB is an active JEDEC TSE2004a1-compliant temperature sensor that serves as a direct drop-in replacement. It offers a larger 4 Kbit EEPROM that is backward compatible with the original 2 Kbit register structure and is fully functional over the same voltage and temperature ranges.
| The AT30TSE002A-MAH-T is an active JEDEC TSE2002a2 temperature sensor that maintains the identical 2 Kbit EEPROM size as the STTS2002. However, it requires a slightly higher minimum supply voltage of 2.7V, making it a partial functional match if the application operates below this voltage.

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 STMicroelectronics STTS2002B2DN3F 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 STMicroelectronics STTS2002B2DN3F are the MCP98244T-BE/MNYAB (Microchip Technology) and the AT30TSE002A-MAH-T (Microchip Technology), 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 STTS2002B2DN3F 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.
