Is there a pin-compatible replacement for CB2012T220K?

Several inductors like MGFL2012F220MT-LF share the same 2012 (0805) package, making them physically compatible. However, electrical parameters like tolerance and saturation current differ and require engineering review before considering them pin-to-pin replacements.

What risks should I check before replacing CB2012T220K?

The main risks are electrical. Ensure the replacement's saturation current is at least 135mA, DC resistance (DCR) is not significantly higher, and the inductance tolerance (target is ±10%) meets your circuit's requirements.

AI replacement insight

Electrical riskhigh

Candidates have weaker tolerance or lower saturation current.

Package risklow

All viable candidates use the same 2012 (0805) package.

Can it be replaced directly?

No direct drop-in replacement was found. All candidates have different tolerance or current ratings that require engineering review.

Best replacement path

MGFL2012F220MT-LF is the most promising path but requires datasheet verification of its saturation current and acceptance of wider tolerance.

Main risk

The primary risk is using a part with lower saturation current, which can lead to performance degradation or failure under load.

Recommended alternatives

Functional alternate in the same 0805 package with lower DCR, but has a wider tolerance.
