AI Summary

INA181A3IDBVT by Texas Instruments: Current Sense Amplifier 1 Circuit Rail-to-Rail SOT-23-6.

The INA181A3IDBVR is the full-reel (3000 piece) packaging variant of the INA181A3IDBVT and serves as an exact silicon and package drop-in replacement. It provides identical 100 V/V gain, 150 kHz bandwidth, and -0.2 V to +26 V common-mode voltage range in the same SOT-23-6 package.

  • 100% pin-compatible drop-in replacement in SOT-23-6 package
  • Identical 100 V/V fixed gain, 150 kHz bandwidth, and -0.2 V to +26 V common-mode voltage range
  • Identical supply current (260 µA max) and 2.7 V to 5.5 V operating supply range

The INA181A2IDBVT belongs to the same INA181 series in an identical SOT-23-6 package and pinout, offering a drop-in physical fit. It provides a lower fixed gain of 50 V/V (versus 100 V/V) while offering higher bandwidth (210 kHz).

  • Pin-compatible drop-in in SOT-23-6 package
  • Higher bandwidth (210 kHz vs 150 kHz)
  • Identical common-mode range (-0.2 V to +26 V) and supply voltage range (2.7 V to 5.5 V)
  • Lower gain (50 V/V vs 100 V/V) results in half the output voltage scaling for a given sense current

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.
