Coilcraft's SER1390-473MLD is a potential starting point as it matches the 47µH inductance, but it has a lower saturation current and temperature rating. Careful engineering review is required.
Best Alternatives to SMDRI127-470MT
SMDRI127-470MT is a 47µH shielded power inductor in a 12.3x12.3x8.0mm package. Finding a direct replacement requires matching inductance, current ratings, DCR, and physical dimensions.
AI replacement insight
Electrical riskhigh
Lower saturation current can lead to performance degradation or failure.
Package riskmedium
Alternatives may have different footprints or heights, requiring PCB changes.
Sourcing risklow
47µH is a common value, but matching all parameters is the challenge.
Can it be replaced directly?
No direct, drop-in replacement was found. All candidates require careful review. SER1390-473MLD matches inductance but fails on saturation current and temperature rating.
Best replacement path
Find an inductor with 47µH inductance, Isat ≥ 4.6A, Irms ≥ 2.5A, and a 12x12mm package. SER1390-473MLD is a starting point but has significant downgrades.
Main risk
The main risks are inductor saturation from lower current ratings and overheating from higher DCR or lower temperature ratings.
