Functional alternative with superior current ratings but a different, larger package requiring board redesign.
WPN252010HR47MT is a 0.47µH wire-wound power inductor from Sunlord in a 2520 package, featuring a 4.7A Irms and 5.2A Isat current rating. Finding a direct drop-in replacement with equivalent or better performance is challenging.
Using pin-compatible parts with lower current ratings may lead to overheating or saturation.
Functional alternates have different footprints and require a PCB redesign.
No direct, pin-compatible replacements with equal or better performance were found. Available pin-compatible options have lower current ratings, requiring careful engineering review.
For new designs, consider functional alternates like MHCI05030-R47M-R8 for higher performance, if the board can be redesigned. For existing boards, VLS252010HBX-R47M-1 is a potential downgrade that requires careful validation.
Electrical overstress due to lower current ratings in form-fit alternatives, or mechanical incompatibility with functional alternates.
