AI Summary

LM393AN by onsemi: Comparator Standard (General Purpose) 8-DIP.

This is the highest-precision active drop-in replacement available, perfectly matching the original 'A' grade's low offset voltage specification.

  • Direct pin-to-pin drop-in replacement in an identical 8-PDIP package.
  • Maintains the same tighter 'A'-grade input offset voltage specification of 2mV max.
  • Highly active lifecycle status ensuring long-term availability.

An excellent, highly-available general-purpose drop-in alternative, though it lacks the tighter offset voltage precision of the original 'A' suffix version.

  • Pin-compatible drop-in replacement in a standard 8-PDIP package.
  • Widely available, highly active industry-standard part.
  • Matches power supply limits and current consumption ratings.
  • Relaxed input offset voltage limit of 5mV max vs the original 2mV max.

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.
