FFF CompatibilityIdentical SOT-23-3 package with the exact same pinout (Pin 1: IN, Pin 2: OUT, Pin 3: GND).Shares the exact same SOT-23-3 physical package dimensions and mounting footprint.Matches all electrical parameters, including 1.25V output, ±0.2% tolerance, 1.8V to 5.5V supply voltage, and 25mA drive current.Identical SOT-23-3 package layout with matching pinout (Pin 1: IN, Pin 2: OUT, Pin 3: GND).Identical mechanical dimensions and SMD footprints.Shares the same 1.25V output, ±0.2% accuracy, and wide temperature range, while offering superior thermal stability.
AI Summary

REF3012AIDBZTG4 by Texas Instruments: Series Voltage Reference IC Fixed 1.25V V ±0.2% 25 mA SOT-23-3.

This is the direct replacement for the obsolete 'G4' suffix version. Texas Instruments retired the 'G4' suffix as all current production parts are green and RoHS-compliant by default.

  • Identical direct replacement from the same manufacturer.
  • 100% pin-compatible and footprint-compatible drop-in.
  • Maintains the exact same ±0.2% tolerance and 25mA output capability.

An upgraded option from the same manufacturer that provides vastly superior thermal stability. It features a much lower temperature coefficient while maintaining exact footprint and pinout compatibility.

  • Significantly improved temperature coefficient of 20ppm/°C vs 75ppm/°C.
  • Directly compatible SOT-23-3 package and pinout.
  • Matches the low minimum input voltage threshold of 1.8V.
  • Lower maximum output current (10mA vs 25mA).
  • Slightly higher typical supply current (135µA vs 50µA).

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 Texas Instruments REF3012AIDBZTG4 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.
