Electrical riskmedium

Vf rises from 0.55V to 0.70V.

Package risklow

SMC package matches.

Firmware risklow

No firmware interface.

Sourcing risklow

Kept parts are indexed and active.

Can it be replaced directly?

Direct replacement for B540C-13-F should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Review B550C-13-F first, then B560C-13-F if higher voltage margin is desired.

Main risk

Both kept candidates have higher forward voltage than B540C-13-F.
