AI replacement insight
Electrical riskmedium
Inductance and DCR differences require circuit validation.
Package risklow
Multiple candidates share the same 3x3mm footprint.
Can it be replaced directly?
No perfect drop-in replacement was found. YHNR3015-100M is the closest form-fit-function match but has a different inductance value that requires review.
Best replacement path
The most promising path is YHNR3015-100M, which matches the package and improves current handling, but requires verifying the impact of its 10µH inductance.
Main risk
The main risk when substituting is the change in inductance, which can affect power converter stability and performance. Lower current ratings in some alternatives also pose a thermal risk.
