LM2902DR
ROHM
Needs validationhigh risk
LM2902DR is a quad op amp candidate only if the 26 V limit is acceptable.
Best Alternatives to LM324ADR
LM324ADR replacements should stay within the quad op amp family and must preserve the 14-pin SOP footprint. External TI B-version parts look promising but need ingestion and pinout review.
