RS8559XP
Runic Technology
Needs validationhigh risk
RS8559XP may suit low-voltage LM324 designs but not 30V rails.
Best Alternatives to LM324
LM324 replacements should first match quad op amp function, SOP14 fit, supply range, and pinout. No listed part is verified drop-in from the provided data.

Can it be replaced directly?
No verified pin-compatible LM324 replacement is proven here.
Best replacement path
Start with BA10324AF-E2, then verify pinout and bandwidth needs.
Main risk
Pinout and supply/application limits are not fully proven.
