A potential drop-in with a matching 1210 package, higher current rating, and wider temperature range.
Finding a replacement for the CMI322513J220KT 22µH inductor involves matching its 1210 package and key electricals. While several functional alternatives exist, NLCV32T-220K-EF offers a similar form factor with improved current and temperature ratings.
Many alternatives have larger footprints, requiring a PCB redesign.
Saturation current is often unspecified and must be verified from datasheets to avoid core saturation.
Yes, TDK NLCV32T-220K-EF is a potential direct replacement for CMI322513J220KT, sharing the same 1210 package and key parameters. Engineering verification is recommended.
The most direct path is NLCV32T-220K-EF, which matches the package size and offers better electrical performance.
The main risk is using a part with a different package, which requires a board layout change. For same-package parts, verify saturation current.
