| FFF Compatibility | Pin 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.
| 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.

You searched one part. Parter watches your whole BOM.
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.
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.
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.
The closest qualified second sources for the ROHM Semiconductor LM324DR are the LM2902DR2G (onsemi) and the LM324DR (Texas Instruments), out of 4 matched alternatives in total. Each is compared against the original on fit, form and function in the table above.
Not always. The alternatives to the LM324DR are matched on function but can differ in package, pinout or a key parameter, so review the fit/form/function notes in the table and the datasheet before designing one in.
The LM324DR (ROHM Semiconductor) is a part in the Linear category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
