Can it be replaced directly?
Direct replacement for FNR5040S100MT should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
Use a 10uH 5x5x4.0 inductor with equal or higher Isat, Irms, and DCR margin.
Main risk
Inductance, current rating, DCR, height, and pinout may not match.
