AI replacement insight

Electrical risklow

Several candidates offer superior current and DCR ratings. The key is verifying the heat rating current (Irms).

Package riskmedium

Many alternatives are not drop-in compatible. Even for same-family packages, footprint verification is critical.

Sourcing risklow

The target and candidates are from common catalog manufacturers, suggesting good availability.

Can it be replaced directly?

CYA0630-47UH is the closest direct replacement candidate, but requires verification of its heat rating current and physical dimensions to confirm it is a true drop-in part.

Best replacement path

The most direct path is CYA0630-47UH, which matches inductance and package family. If board redesign is possible, parts like SMMS1360-470M offer superior electrical performance.

Main risk

The main risk is ensuring the replacement's current handling (both saturation and heat rating) and physical footprint match the application's requirements.

Recommended alternatives

A potential form-fit replacement with matching inductance, lower DCR, and higher saturation current. Review required.
