Can it be replaced directly?

Direct replacement for FHD4020S-2R2MT should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Use YNR4020-2R2N only for derated current, or FHD4020S-1R5MT if 1.5uH is acceptable.

Main risk

Inductance and current ratings are not fully aligned.
