Can it be replaced directly?

Direct replacement for DSS310 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Search for a 3A or higher, 100V+ Schottky in SOD-123FL with verified polarity.

Main risk

Most candidates are only 1A, far below DSS310.
