Is there a pin-compatible replacement for HC-XH-3Y?

Yes, there are many likely pin-compatible replacements from different manufacturers, as this is a standard connector type. However, you must verify the mechanical drawings in the datasheet to confirm the PCB footprint and dimensions are an exact match before ordering.

What risks should I check before replacing HC-XH-3Y?

The main risk is mechanical mismatch. Check the datasheet for the PCB footprint, pin diameter, and the plastic shroud's height and width to ensure it fits your board and mates correctly with the corresponding female connector. Electrical risks are low if the voltage and current ratings match.

AI replacement insight

Electrical risklow

Most alternatives match the 3A, 250V rating.

Package riskmedium

Requires datasheet review to confirm PCB footprint and mating compatibility.

Sourcing risklow

The XH connector style is widely available from many vendors.

Can it be replaced directly?

Yes, several manufacturers produce headers intended to be compatible with HC-XH-3Y. Candidates like ZX-XH2.54-3PZZ-Y and XH-D-3A are strong matches but require mechanical verification.

Best replacement path

Cross-reference to other manufacturers' 3-pin, 2.5mm pitch XH-series headers like those from Megastar, DEALON, or ZHOURI.

Main risk

The primary risk is mechanical incompatibility. While pitch and pin count match, the PCB footprint, shroud height, and material could differ slightly.

Recommended alternatives

A 3-pin, 2.5mm pitch header from ZHOURI with matching electrical ratings and package.
