Texas Instruments TMP275AIDG
TMP275AIDG variants from Texas Instruments
TMP275AIDG Overview
What changes between part numbers, and what to check before you lock the BOM — Sensors.
Key Features
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 2 distinct suffix patternsExamples: KR, KT. Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- Sensors — design-in and field replacement
- BOM scrub where only the base prefix is known but suffix is TBD
- Second-source checks when the original MPN is constrained
Ordering Variants
Compare 2 TMP275AIDG part numbers by package, electrical parameters, lifecycle, and availability. Use RFQ for stock and lead-time confirmation.
| Part Number | Description | Manufacturer | Lifecycle | RoHS | Availability | Action |
|---|---|---|---|---|---|---|
| TMP275AIDGKR | Digital Humidity Sensor, 12-bit, I2C/SMBus, VSSOP, -40°C to 125°C | Texas Instruments | Active | Compliant | In Stock | |
| TMP275AIDGKT | 12-Bit Digital Temp Sensor, I2C/SMBus, -40 to 125°C, VSSOP | Texas Instruments | Active | Compliant | In Stock |

How to Choose the Right TMP275AIDG Sensors
Match the footprint first
Pull the exact package drawing for your MPN — base-number swaps fail most often at the footprint, not the schematic.
Electrical headroom
Compare voltage and current columns in the variant table. For TMP275AIDG, a suffix with lower voltage or current rating will not survive the same circuit without recalculation.
Temp grade letter matters
Commercial (0–70 °C) and industrial (−40–85 °C+) suffixes look similar in the prefix — confirm ambient + self-heating, not just the first page of the datasheet.
Copy the full MPN
Do not BOM only "TMP275AIDG" — include the full suffix (e.g. KR, KT). RFQ with reel/tube preference and required date code.
