Can it be replaced directly?

Direct replacement for DLW43SH510XK2L should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Check 1812 common-mode chokes with 51uH, 4-pin pinout, 50Vdc or higher, and impedance curves.

Main risk

Pinout and footprint are not proven for the kept candidates.
