Can it be replaced directly?
Direct replacement for CUS10S30,H3F should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
Look first for a 30V or higher 1A Schottky in USC/SC-76/SOD-323 with matching polarity.
Main risk
Package mismatch: all candidates use SMA, SMB, or SMAF packages.
