Can it be replaced directly?

Direct replacement for PBSS4140T,215 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Check PBSS4130T,215 only if the circuit can accept a 30V VCEO limit.

Main risk

Lower voltage rating and unverified pinout.
