Can it be replaced directly?

Direct replacement for TLP172GM(TPL,E should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Start with same-package Toshiba photorelays only for derated low-voltage designs, then verify pinout and ratings.

Main risk

The major gap is load voltage: kept candidates are rated 60V versus the 350V target.
