HC-XA-2A is a standard 2-pin, 2.5mm pitch straight header. Many cross-vendor alternatives with identical form, fit, and function are available, requiring only datasheet verification of mechanical drawings.

AI replacement insight

Electrical risklow

Ratings are identical across candidates.

Package risklow

XH is a standard, but datasheet verification of dimensions is required.

Can it be replaced directly?

Yes, multiple manufacturers produce 2-pin, 2.5mm pitch straight headers that are form, fit, and function compatible. Candidates from HCTL, Megastar, and others are strong matches.

Best replacement path

Use other HCTL XHB-2A series parts or verified cross-vendor XH-2P connectors.

Main risk

Minor variations in housing material, exact pin length, or housing dimensions.
