AI Summary

LM2903VQPWRG4 by Texas Instruments: Comparator Standard (General Purpose) Open-Collector, Rail-to-Rail 8-TSSOP.

This is a high-precision drop-in sibling from the same family. It offers a significantly improved (lower) input offset voltage limit of 2mV compared to the original's 7mV, making it an excellent upgrade for systems requiring tighter voltage thresholds.

  • Tighter maximum input offset voltage of 2mV (at 5V) compared to the original 7mV, improving measurement precision
  • AEC-Q100 qualified for high-reliability automotive environments
  • Full pin-to-pin drop-in compatibility in the TSSOP-8 package

This is the exact direct replacement for the obsolete LM2903VQPWRG4. The only difference is the removal of the legacy 'G4' suffix, which was TI's older lead-free nomenclature that has since been integrated into the standard MPN. This replacement is active, fully RoHS compliant, and requires no design modifications.

  • Exact electrical and physical drop-in equivalent from the same manufacturer
  • Maintains full AEC-Q100 automotive qualification and same -40°C to 125°C temperature range
  • Identical TSSOP-8 package outline with 0.65mm pin pitch

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.
