SHOU HAN
A functional alternative with 4.7µH inductance, much higher current ratings, and lower DCR, but in a different package.
Find functional alternatives for the Vishay IHLP2525CZER4R7M01 4.7µH power inductor. This analysis identifies several options with superior electrical performance, though they require board layout changes due to different package sizes.
All candidates have a different, larger footprint, requiring a new PCB layout.
Candidates offer higher current ratings and lower DCR, which is generally a safe upgrade.
No direct, drop-in replacement was found. While many inductors match the 4.7µH value with superior current handling, they are not in the same 2525 package.
Functional upgrade requiring board redesign.
Package mismatch requiring PCB redesign.
