Can it be replaced directly?
Direct replacement for AOZ1282CI should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
Start with EUP3458VIR1 only if a 30V input limit is acceptable and pinout is verified.
Main risk
Pinout and input-voltage rating are the main risks.
