| FFF Compatibility | The part uses the identical 14-pin SOIC footprint (Case 751A) with the exact same pinout configuration.The physical dimensions and package are completely identical to the obsolete LM324D.The electrical specifications, including the 1 MHz bandwidth, supply voltage range (3V to 32V), and offset voltage match exactly. | Uses the identical 14-pin SOIC layout with matching pin assignments.Identical physical dimensions and SOIC-14 package envelope.Fully compatible electrical behavior with upgraded precision (lower input offset voltage). | ||
 AI Summary | LM324D by onsemi: Operational Amplifiers - Op Amps 3-32V Quad 5mV VIO. | This is the active, direct replacement from onsemi. The only difference is the packaging format: LM324DR2G is supplied on Tape & Reel, whereas the obsolete LM324D was packaged in Tubes.
| This is an active upgraded sibling from the same onsemi series. It features a tighter input offset voltage tolerance (2 mV maximum vs 5 mV), providing better accuracy while remaining a direct mechanical and electrical drop-in.

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 onsemi LM324D 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 onsemi LM324D are the LM324DR2G (onsemi) and the LM324ADR2G (onsemi), out of 5 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 LM324D 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 LM324D (onsemi) is a part in the Operational Amplifiers - Op Amps category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
