Electrical riskmedium

closest options change L or current ratings

Package riskmedium

5040 matches but pad layout is not verified

Firmware risklow

passive part; control-loop tuning may still matter

Sourcing riskmedium

lifecycle fields vary by candidate

Can it be replaced directly?

No verified pin-compatible replacement is proven from the provided data.

Best replacement path

Review FNR5040S180MT first if lower current margin is acceptable; check YNR5040-100M for redesign cases.

Main risk

Current rating, inductance shift, DCR heating, and unverified pinout.
