Finding a replacement for the SLM25202R2MIT 2.2µH inductor involves matching its 2520 package, inductance, and electrical ratings. Several strong upgrades with higher current handling are available.

AI replacement insight

Electrical riskmedium

Unknown target Isat requires verification. DCR mismatch in some candidates.

Package risklow

All candidates are in a compatible 2520/1008 package.

Can it be replaced directly?

No exact 1:1 replacement is identified, but several parts like WIP252012P-2R2ML offer a form-fit upgrade with superior performance. Review of DC resistance (DCR) and saturation current (Isat) is critical.

Best replacement path

Upgrade to an automotive-grade part like TDK's TFM252012ALVA2R2MTAA or INPAQ's WIP252012P-2R2ML for significantly better current ratings with a similar DCR and package.

Main risk

The primary risk is the unknown saturation current (Isat) of the original part. A secondary risk is increased power loss if a substitute with higher DC Resistance (DCR) is chosen.
