Texas Instruments TL431AILP
TL431AILP variants from Texas Instruments
TL431AILP Overview
What changes between part numbers, and what to check before you lock the BOM — Voltage References.
TL431AILP is a Texas Instruments order-code family — not a single orderable MPN. This page lists 3 variants that share the same core device but differ in suffix fields (package, grade, reel/tube, electrical bin, etc.). Pick the exact full part number; substituting within the family without checking the datasheet often causes assembly or spec mismatches.
Package: TO-92-3 | Output Voltage: 36V | Output Current: 100mA | Max Output Current: 100mA | Max Input Voltage: 37V | Number of Channels: 1 | Max Operating Temp: 125°C | Min Operating Temp: -40°C Other listed variants describe: V-Ref Adjustable 2.495V to 36V 100mA Automotive 3-Pin TO-92 T/R; Package: TO-226-3, TO-92-3 (TO-226AA) | Mounting Type: Through Hole | Operating Temperature: -40°C ~ 85°C (TA) | Tolerance: ±1% | Output Type: Adjustable | Supplier Device Package: TO-92-3.
Across listed variants, watch these parameters: packages: TO-92-3, TO-226-3, TO-92-3 (TO-226AA).
Suffix examples in this family: M, R. The characters after the base number usually encode package, temperature, or performance grade — compare the variant table column-by-column rather than assuming pin-compatible drops-in.
Columns that actually vary on this page: Package Type. If two rows match on MPN prefix but differ there, they are not interchangeable for production.
Example MPNs: TL431AILPM, TL431AILPR, TL431AILP.
Key Features
- Footprint / package: TO-92-3, TO-226-3, TO-92-3 (TO-226AA)Land pattern and thermal pad differ between these packages — run a quick footprint check before you swap variants.
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 2 distinct suffix patternsExamples: M, R. Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- Voltage References — 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

Compare 3 TL431AILP part numbers by package, electrical parameters, lifecycle, and availability. Use RFQ for stock and lead-time confirmation.
| Part Number | Description | Package Type | Manufacturer | Lifecycle | RoHS | Availability | Action |
|---|---|---|---|---|---|---|---|
| TL431AILPM | Package: TO-92-3 | Output Voltage: 36V | Output Current: 100mA | Max Output Current: 100mA | Max Input Voltage: 37V | Number of Channels: 1 | Max Operating Temp: 125°C | Min Operating Temp: -40°C | TO-92-3 | Texas Instruments | Active | Compliant | In Stock | |

Ordering Code Differences
How suffixes on TL431AILP map to package, grade, and reel options.
TL431AILP uses a shared prefix; characters after the prefix encode orderable options. Two lines with the same prefix are not drop-in replacements unless the differing columns match your need.
Suffixes seen here: M, R.
What changes between rows: Package Type. Sort the table by these columns when narrowing from base number to a single MPN.
Full MPN examples: TL431AILPM, TL431AILPR.
Tip: photograph or copy the reel label — reel diameter, QTY per reel, and moisture sensitivity level (MSL) are often suffix-driven and won't show in the schematic.
How to Choose the Right TL431AILP Voltage References
Match the footprint first
Packages here: TO-92-3, TO-226-3, TO-92-3 (TO-226AA). Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For TL431AILP, 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 "TL431AILP" — include the full suffix (e.g. M, R). RFQ with reel/tube preference and required date code.
