| FFF Compatibility | The physical package and pin assignments are identical (Pin 1: SCL, Pin 2: GND, Pin 3: ALERT, Pin 4: V+, Pin 5: ADD0, Pin 6: SDA).Housed in the identical SOT-23-6 (DBV) package.Maintains the same 9-to-12-bit resolution, I2C/SMBus interface, and 2.7V to 5.5V supply range. | The pin assignments match the original TMP101 standard perfectly.Manufactured in the same SOT-23-6 physical dimensions.Operates identically with 2.7V to 5.5V supply and -55°C to 125°C temperature range. | ||
 AI Summary | TMP101NA/250G4 by Texas Instruments: Temperature Sensor Digital, Local -55°C ~ 125°C 11 b SOT-23-6. | This is the direct active sibling of the obsolete TMP101NA/250G4. The only difference is the tape-and-reel quantity (3,000-piece reel instead of 250-piece reel) and the transition away from the legacy G4 suffix.
| A direct pin-to-pin and software-compatible second-source clone of the TMP101 series. It is an active part and serves as an excellent replacement to mitigate single-source manufacturer risk.

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 TMP101NA/250G4 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 TMP101NA/250G4 are the TMP101NA/3K (Texas Instruments) and the UMW TMP101 (UTD Semiconductor (UMW)), 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 TMP101NA/250G4 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 TMP101NA/250G4 (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.
