AI Summary

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.

  • Pin-compatible drop-in replacement with identical SOT-23 package and pinout assignment
  • High precision ±0.5% tolerance matches the original GOODWORK specification
  • Extended operating temperature range of -40°C to 85°C versus the original 0°C to 70°C

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.

  • Pin-compatible drop-in replacement with identical SOT-23 package and pinout assignment
  • High precision ±0.5% tolerance matches the original GOODWORK specification
  • Sourced from Nexperia, providing an excellent alternative manufacturer channel

You searched one part. Parter watches your whole BOM.

  1. 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.

  2. 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.

  3. 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
