Can it be replaced directly?

Direct replacement for PBSS5350Z,135 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Review BCP53TF only for derated low-current use.

Main risk

Candidate current rating is far below the target.
