Electrical upgrade with much higher current ratings and similar DCR, but in a larger package.
Finding a replacement for the CY75-22UH, a 22µH power inductor in a 7.8x7.0mm package, requires careful consideration of functional alternatives as no direct drop-in replacements are readily available. Key parameters to check are package size, DCR, and current ratings.
No candidates match the 7.8x7.0mm footprint. PCB redesign is mandatory.
Many candidates have higher DCR, increasing power loss. The target's saturation current is unknown, making peak current handling a risk.
Multiple functional alternates from different manufacturers are available.
No direct drop-in or pin-compatible replacements were found. All reviewed candidates have different package footprints, requiring a PCB redesign.
Use a functional alternate like PSPMAA1040H-220M-ANP for an electrical upgrade, but this requires a PCB layout change for its larger package.
The primary risk is physical incompatibility. All potential substitutes have different package sizes and require a board layout change.

The best alternative depends on your design constraints. For an electrical upgrade, PSPMAA1040H-220M-ANP offers much higher current handling but is physically larger. For a similar performance profile, VLS6045EX-220M is an option, but has a different footprint and higher DCR.
