Is there a pin-compatible replacement for SMCM090605-472?

Yes, other parts in the SXN SMCM090605 series, like SMCM090605-102, share the same 090605 package and pinout. However, their electrical parameters, especially inductance, differ significantly and must be verified for your application.

What risks should I check before replacing SMCM090605-472?

The primary risk is electrical mismatch. Verify the substitute's inductance and impedance at your operating frequency, as these directly impact filtering performance. Also confirm the current rating and DC resistance (DCR) meet your design's requirements.

SMCM090605-472 Alternatives, Datasheet & Cross Reference | SXN

SMCM090605-472 is a 4700 µH surface-mount common mode choke from SXN, designed for signal line noise suppression with a 0.5A current rating. Finding a direct replacement requires matching its high inductance and 090605 package.

AI replacement insight

Electrical riskhigh

Most alternatives have much lower inductance, which will change filter characteristics.

Package risklow

Alternatives in the same family share the package, but cross-vendor parts may differ.

Can it be replaced directly?

No direct, one-to-one replacement has been identified. Alternatives exist within the same product family but have significantly different inductance values, requiring engineering review.

Best replacement path

Find a common mode choke with an inductance near 4700 µH in a compatible 090605 package.

Main risk

Significant reduction in filtering performance due to lower inductance in available alternatives.

Recommended alternatives

Form-factor compatible alternative with higher current rating but much lower inductance. Requires engineering review.
