| FFF Compatibility | Pinout is identical (Pin 1: Cathode, Pin 2: Ref, Pin 3: Anode) allowing a true drop-in replacement.Housed in the same industry-standard SOT-23-3 package with identical mechanical footprint.The ±0.5% reference voltage tolerance, 100 mA cathode current capability, and 36V maximum shunt voltage meet or exceed the original part's electrical limits. | Pinout is identical (Pin 1: Cathode, Pin 2: Ref, Pin 3: Anode) allowing a true drop-in replacement.Housed in the same industry-standard SOT-23-3 package with identical mechanical footprint.Matches the original 0.5% reference tolerance and has equivalent 100 mA current capability and 36V rating. | ||
TL431 by GOODWORK: Voltage Reference IC Adjustable (Fixed) 2.55 VV ±0.5% 100 mA SOT-23. | This high-precision shunt regulator from Texas Instruments is an excellent replacement that directly matches the ±0.5% tolerance of the original GOODWORK part. It offers improved thermal stability and an expanded temperature range. No circuit redesign is required.
| Nexperia's high-precision variant offers a direct drop-in replacement matching the ±0.5% reference tolerance of the original part. It serves as an excellent second-source equivalent with identical electrical behavior over the 0°C to 70°C temperature range.

You searched one part. Parter watches your whole BOM.
All your BOM, at once
Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.
Hear about problems before they hit production
Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.
Qualified replacements in minutes, not days
Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
Frequently asked questions
Yes. The GOODWORK TL431 is active and in production. The parts listed here are qualified equivalents if you need a second source or better availability.
The closest qualified second sources for the GOODWORK TL431 are the TL431BIDBZR (Texas Instruments) and the TL431BCDBZR (Nexperia), out of 4 matched alternatives in total. Each is compared against the original on fit, form and function in the table above.
Not always. The alternatives to the TL431 are matched on function but can differ in package, pinout or a key parameter, so review the fit/form/function notes in the table and the datasheet before designing one in.
The TL431 (GOODWORK) is a part in the Power Management (PMIC) category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
