PDF review is still pending.

Can it be replaced directly?

Direct replacement for B240A-13-F should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Review B340A-13-F first, then B340LA-13-F or B360A-13-F if limits fit.

Main risk

Pinout is not verified and low-temperature/VF limits may differ.
