|---|---|---|---|---|
| FFF Compatibility | Pinout, pitch, and pad assignments are 100% identical as it uses the exact same VSSOP-8 package design.Identical VSSOP-8 (DGK) package dimensions and mechanical footprint.Identical electrical characteristics, 2.7V to 5.5V operating voltage, and software registers. | The pinout assignments for SCL, SDA, ALERT, GND, address pins (A0, A1, A2), and power are identical.The 8-MSOP package shares identical mechanical dimensions and PCB land pattern requirements with the 8-VSSOP package.Meets or exceeds all performance specifications, including operating voltage, resolution (up to 12-bit), and temperature range. | ||
 AI Summary | TMP275AIDGKT by Texas Instruments: Temperature Sensor Digital, Local -40°C ~ 125°C 11 b 8-VSSOP. | This is the direct, active manufacturer replacement for the obsolete TMP275AIDGKT, differing only in the larger factory packaging reel size (Tape & Reel vs Small Tape & Reel). It offers a 100% seamless, zero-risk drop-in replacement with no physical, electrical, or software modifications required.
| The MCP9808 is an exceptional second-source digital temperature sensor offering equivalent or superior accuracy and a fully compatible 2.7V to 5.5V supply voltage. It serves as a reliable, active alternative from a different manufacturer on the same footprint.

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 Texas Instruments TMP275AIDGKT 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 Texas Instruments TMP275AIDGKT are the TMP275AIDGKR (Texas Instruments) and the MCP9808-E/MS (Microchip Technology), 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 TMP275AIDGKT 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 TMP275AIDGKT (Texas Instruments) is a part in the Temperature Sensors category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
