FFF CompatibilityPin assignment verified one-to-one across all 14 pins; uses the standard SOIC-14 footprint.SOP-J14 and SOIC-14 (0.154-inch/3.90mm narrow body width) packages are mechanically interchangeable.Meets or exceeds all key electrical specifications, including the full -40°C to +85°C temperature range and the 32 V maximum supply ceiling.Identical standard pin assignments (1 to 14) for quad operational amplifiers.Narrow-body SOIC-14 package is a physical drop-in equivalent for Rohm's SOPJ-14.Operating temperature is limited to 0°C to 70°C (vs -40°C to +85°C) and maximum supply is limited to 30 V (vs 32 V).
AI Summary

LM324DR by ROHM Semiconductor: Standard (General Purpose) Amplifier 4 Circuit 14-SOPJ.

This is an exceptional replacement choice for applications requiring the full industrial temperature range. It matches the original 32 V supply maximum and extends the operating temperature up to +105°C. It is a highly active and widely available component from onsemi's standard linear portfolio.

  • Extended operating temperature range of -40°C to +105°C fully covers the original part's range (-40°C to +85°C)
  • Identical pinout and package (SOIC-14, 3.90mm width) for direct drop-in board mounting
  • Maintains the original part's maximum 32 V supply voltage limit
  • Higher typical input bias current (90 nA vs 20 nA on the original Rohm part)
  • Slightly lower typical bandwidth (1.0 MHz vs 1.2 MHz on the original)

The industry-standard quad op-amp drop-in from Texas Instruments is highly cost-effective and globally sourced. It serves as an excellent functional replacement for non-temperature-critical commercial designs, although it has a narrower operating temperature range and a slightly lower 30 V supply limit.

  • Industry-standard general-purpose quad op-amp replacement widely stocked by major distributors
  • Identical pinout and narrow-body SOIC-14 footprint with direct board compatibility
  • Maintains the 1.2 MHz gain bandwidth product of the original Rohm design
  • Narrower operating temperature range (0°C to 70°C vs -40°C to +85°C on the original part)
  • Slightly lower maximum supply voltage ceiling (30 V vs 32 V)

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 LM324DR 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.
