AI Summary

LM339DR by ROHM Semiconductor: Comparator Standard (General Purpose) CMOS, MOS, Open-Collector, TTL 14-SOIC.

Diodes Incorporated's AS339MTR-G1 is a highly compatible drop-in replacement that perfectly matches the 2V to 36V supply voltage capabilities of the obsolete Rohm device. It also provides an upgraded operating temperature range (-40°C to 85°C) and lower power consumption. This active lifecycle part is widely available as a direct replacement.

  • Drop-in pin-to-pin compatible in standard 14-SOIC package
  • Identical supply voltage range from 2V to 36V (±1V to ±18V)
  • Extended temperature range (-40°C to 85°C vs 0°C to 70°C for Rohm)

The onsemi LM339DR2G is a widely used drop-in replacement that matches Rohm's maximum supply voltage rating of 36V. However, it requires a slightly higher minimum supply voltage of 3V rather than 2V. It is a highly active and widely stocked component suitable for most designs.

  • Drop-in pin-to-pin compatible in standard 14-SOIC package
  • Matches the 36V maximum supply voltage of the original Rohm part
  • Active and highly reliable line from onsemi
  • Higher minimum supply voltage requirement (3V vs 2V)

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 ROHM Semiconductor LM339DR 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.
