Is there a pin-compatible replacement for HX CYA1050-4.7UH?

Yes, other inductors in the Hanxia CYA1050 series share the same package and pinout. However, available candidates have different inductance values, making them functional but not direct electrical replacements. Always verify the inductance requirement for your application.

What risks should I check before replacing HX CYA1050-4.7UH?

The main risk is an inductance mismatch, which will alter circuit performance (e.g., ripple current, stability). Also verify saturation current (Isat), DC current rating (Idc), and package height are suitable for your design.

AI replacement insight

Electrical riskhigh

Inductance is a primary functional parameter; mismatch requires redesign.

Package risklow

Footprint matches are available, but height may vary between series.

Can it be replaced directly?

No direct replacement with identical key parameters was found. Available alternatives require engineering review due to different inductance values, which will impact circuit performance.

Best replacement path

Find an inductor with matching 4.7µH inductance, ≥15A Isat, ≥12A Idc, and a compatible 11.6x10.1mm footprint.

Main risk

An inductance mismatch will alter DC-DC converter performance, affecting ripple current, efficiency, and stability.

Recommended alternatives

Form-fit compatible with higher current ratings, but has lower inductance.
