Is there a pin-compatible replacement for CYA1265-4.7UH?

No pin-to-pin compatible replacement has been verified. Candidates may have slightly different package dimensions or electrical parameters that require engineering validation before use.

What risks should I check before replacing CYA1265-4.7UH?

Key risks include lower saturation current (Isat) causing core saturation, lower heat rating current (Idc) causing overheating, higher DCR reducing efficiency, and package dimension differences affecting PCB layout.

AI replacement insight

Electrical riskhigh

Many candidates have lower current ratings or different inductance.

Package riskmedium

Some candidates have slightly different package dimensions that may not fit the existing PCB footprint.

Firmware risklow

Inductors are passive components and do not involve firmware.

Can it be replaced directly?

No, a direct, drop-in replacement for the CYA1265-4.7UH has not been identified. All candidates require engineering review due to parametric or package differences.

Best replacement path

No direct replacement found. Evaluate a parametrically similar but weaker part like MWSA1206S-4R7MT for non-critical applications, or select a different value from the same CYA1265 series if the circuit design allows.

Main risk

The main risk is using a substitute with lower current ratings (Isat/Idc), which can lead to inductor saturation, overheating, and circuit failure under load.

Recommended alternatives

A same-series inductor with different inductance (3.3uH) but higher current ratings and lower DCR.
