Texas Instruments TMCS1101A
TMCS1101A variants from Texas Instruments
TMCS1101A 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.
- 12 distinct suffix patternsExamples: 1BQDR, 1BQDRQ1, 2BQDR, 2BQDRQ1, 2UQDRQ1 (+7 more). 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

How to Choose the Right TMCS1101A 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 TMCS1101A, 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 "TMCS1101A" — include the full suffix (e.g. 1BQDR, 1BQDRQ1, 2BQDR). RFQ with reel/tube preference and required date code.
