APV
A functional alternative with higher current ratings but in a larger package not suitable for drop-in replacement.
Explore functional alternatives for the YHNR4020-6R8M inductor. While no direct drop-in replacements are available, several candidates offer superior current handling and lower resistance in different packages, suitable for new designs or board revisions.
All candidates have larger footprints and will not fit on the existing PCB land pattern.
All candidates meet or exceed the target's current ratings and have lower DCR, representing an electrical upgrade.
There is no direct, drop-in replacement for the YHNR4020-6R8M. All alternatives require a PCB layout change due to different package sizes.
For a board redesign, FAUL0530-6R8MT is the smallest alternative. For higher performance, consider FXL0840-6R8-M or FAUL1050-6R8MT depending on space.
Package incompatibility is the main risk, as no alternatives share the target's 4.0x4.0mm footprint.
