A close form-fit-function match, but has a slightly lower RMS current rating that requires verification.
Finding a substitute for the CMPI0530-2R2M 2.2µH power inductor involves balancing package compatibility and electrical performance. While no exact drop-in is found, one near form-fit option and several electrical upgrades with different footprints are available.
Most candidates have different footprints, requiring a board spin.
Most candidates meet or exceed electrical specs. One near-match has slightly lower RMS current.
No exact drop-in replacement has been identified. The closest candidate, SLO0530H2R2MTT, has a compatible package but a slightly lower RMS current rating (5.5A vs 6.0A) that must be verified for the application.
SLO0530H2R2MTT offers a compatible footprint but requires checking its slightly lower 5.5A RMS current rating. For new designs, TDK's SPM6530T-2R2M is a strong electrical upgrade.
The primary risk for most alternatives is package incompatibility, requiring a PCB redesign. For the closest form-fit option, the risk is a minor electrical derating on RMS current.
