What risks should I check before replacing CYA0630-33UH?

Key risks include package/footprint mismatch, especially height clearance. Also, check for differences in DC Resistance (DCR), which affects efficiency, and ensure the saturation (Isat) and RMS (Irms) currents meet or exceed your application's requirements.

CYA0630-33UH Alternatives, Datasheet & Cross Reference | SHOU HAN

Finding a replacement for the SHOU HAN CYA0630-33UH 33µH power inductor involves matching the 0630 package, 2.9A saturation current, and 225mΩ DCR. Several alternatives offer improved current handling or lower DCR in a similar footprint.

AI replacement insight

Package riskmedium

Several parts use the '0630' package, but dimensions and land patterns can vary slightly.

Electrical risklow

Many alternatives offer superior current handling and comparable or lower DCR.

Can it be replaced directly?

Direct replacement for CYA0630-33UH should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Prioritize candidates in the same 0630 package, such as SLO0630H330MTT, which offers lower DCR and higher current ratings.

Main risk

The primary risk is physical incompatibility due to slight package dimension differences (especially height) or land pattern variations.

Recommended alternatives

Excellent alternative with matching package, lower DCR, and higher current ratings.
