AI Summary

TL431CDG by onsemi: Voltage Reference IC V.

This is the exact active equivalent of the queried part from the same manufacturer, differing only in the delivery format (Tape & Reel instead of Tube).

  • Identical chip and electrical performance from the original manufacturer
  • Direct drop-in replacement on the existing PCB footprint
  • Active lifecycle status ensures long-term availability
  • Delivered in Tape & Reel packaging instead of Tube packaging

This is a highly reliable direct second-source alternative from Texas Instruments that matches all electrical, physical, and packaging attributes of the obsolete part.

  • Active product status from a premium manufacturer (Texas Instruments)
  • Maintains identical Tube packaging style as the original part
  • Direct second-source equivalent with identical electrical parameters

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

Yes. The onsemi TL431CDG is marked obsolete, so the manufacturer has discontinued it and any remaining supply is limited to distributor stock. The qualified second sources on this page are active parts you can design in today.
