Is there a pin-compatible replacement for WF-1A125A4P?

Several candidates like HCTL HC-1.25-4Y appear to be pin-compatible, sharing the same 4-pin, 1.25mm pitch, and straight through-hole configuration. However, you must verify the detailed mechanical drawings in the datasheet to confirm a perfect fit on your PCB.

What risks should I check before replacing WF-1A125A4P?

Before replacing, you must verify the substitute's mechanical dimensions from its datasheet to ensure it fits your PCB layout. Also, confirm that its electrical ratings (voltage, current) and temperature range are suitable for your application.

AI replacement insight

Package riskmedium

Slight variations in housing dimensions or pin length can cause issues. Datasheet check is essential.

Electrical risklow

For selected candidates, electrical ratings are matched or improved, posing low risk.

Can it be replaced directly?

No drop-in replacement has been fully verified. HCTL HC-1.25-4Y is a promising candidate that requires datasheet verification of mechanical dimensions before use.

Best replacement path

HCTL HC-1.25-4Y is a strong functional match, while BOOMELE 1.25T-4A米色 offers an electrical upgrade. Both require mechanical verification.

Main risk

The primary risk is mechanical incompatibility. Substitutes must match the 1.25mm pitch, 4-pin, straight through-hole footprint precisely.

Recommended alternatives

Strong functional match with identical key electrical ratings and package type.
