Texas Instruments REF02AU
REF02AU variants from Texas Instruments
REF02AU Overview
What changes between part numbers, and what to check before you lock the BOM — Microcontrollers.
Key Features
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
Target Applications
- Microcontrollers — 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 REF02AU 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 |
|---|---|---|---|---|---|---|
| REF02AU | 5V Precision Voltage Reference IC, 21mA, 8-Pin SOIC | Texas Instruments | Active | Compliant | In Stock | |
| REF02AU/2K5 | Wide supply range, 5-V output precision voltage reference 8-SOIC -40 to 85 | Texas Instruments | Active | Compliant | In Stock |

How suffixes on REF02AU map to package, grade, and reel options.
How to Choose the Right REF02AU Microcontrollers
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 REF02AU, 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 "REF02AU" — include the full suffix (e.g. 2K5). RFQ with reel/tube preference and required date code.
