Texas Instruments TL1963A
TL1963A variants from Texas Instruments
TL1963A Overview
What changes between part numbers, and what to check before you lock the BOM — Integrated Circuits (ICs).
Key Features
- Footprint / package: SOT-223-6Single package option across listed variants; still confirm reel vs tube suffix if you auto-insert.
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 11 distinct suffix patternsExamples: 25DCQT, 15DCQR, 15DCQT, 15DCYR, 15DCYT (+6 more). Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- Integrated Circuits (ICs) — 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 TL1963A Integrated Circuits (ICs)
Match the footprint first
Packages here: SOT-223-6. Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For TL1963A, 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 "TL1963A" — include the full suffix (e.g. 25DCQT, 15DCQR, 15DCQT). RFQ with reel/tube preference and required date code.
