AI Summary

1N4371A by onsemi: Zener Diode 2.7 V 500 mW ±5% Through Hole DO-35.

The 1N5223B is a direct drop-in replacement with identical electrical and physical characteristics.

  • Drop-in compatible DO-35 package
  • Identical 2.7 V Zener voltage with ±5% tolerance
  • Same 500 mW power rating and -65°C to +200°C temperature range

This alternative has a slightly shifted Zener voltage window, different test current, and narrower operating temperature range.

  • Pin-compatible axial DO-35 package
  • Same 500 mW power rating
  • Narrower operating temperature range: -65°C to 175°C vs -65°C to 200°C
  • Shifted Zener voltage range: 2.7V to 2.9V vs 2.57V to 2.84V

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.
