Is there a pin-compatible replacement for NLCV32T-220K-EF?

CMI322513J220KT is a form-fit match (1210 package), but it is not a direct pin-to-pin replacement due to a lower current rating and operating temperature. Electrical validation is required.

What risks should I check before replacing NLCV32T-220K-EF?

Key risks include: 1) Current Rating: Ensure the replacement handles at least 300mA. 2) Temperature Range: The replacement must meet or exceed the -40°C to +105°C range. 3) DCR: Higher DCR increases power loss. 4) Package: Ensure the footprint matches your PCB layout.

NLCV32T-220K-EF Alternatives, Datasheet & Cross Reference | TDK Electronics AG

NLCV32T-220K-EF is a 22µH, 300mA wound ferrite inductor in a 1210 package. Finding a direct drop-in replacement requires careful review of current rating and operating temperature.

AI replacement insight

Electrical riskhigh

Form-fit options have lower current/temp ratings; functional alternatives have different construction or tolerance.

Package riskmedium

Only one candidate matches the package. Others require a PCB redesign.

Can it be replaced directly?

No direct, fully equivalent drop-in replacement was found. CMI322513J220KT is a form-fit match with parametric downgrades that require engineering review.

Best replacement path

The most direct path is CMI322513J220KT, which matches the package but requires verifying if the lower current (250mA) and temperature (85°C) are acceptable.

Main risk

The primary risk is finding a part in a 1210 package that matches or exceeds both the 300mA current rating and 105°C operating temperature.

Recommended alternatives

Same package and inductance, but lower current rating and operating temperature require careful review.
