Is there a pin-compatible replacement for HC-XA-4A?

While several parts are functionally and mechanically similar, a guaranteed pin-compatible replacement requires comparing the mechanical drawings in the datasheets. No candidate is pre-verified as pin-to-pin.

What risks should I check before replacing HC-XA-4A?

First, confirm the candidate's mounting orientation (straight vs. right-angle). Second, verify all mechanical dimensions from the datasheet. Finally, ensure the voltage, current, and temperature ratings meet or exceed the original part's specifications.

HC-XA-4A Alternatives, Datasheet & Cross Reference | HCTL

HC-XA-4A is a standard 4-pin, 2.5mm pitch straight through-hole header. Alternatives are widely available but require careful verification of mechanical dimensions and electrical ratings to ensure compatibility.

AI replacement insight

Package riskmedium

Slight variations in housing/pin dimensions between manufacturers can affect fit.

Electrical risklow

Most XH-series equivalents have similar 3A/250V ratings, but verification is still needed.

Can it be replaced directly?

No pre-verified pin-to-pin replacement is available. Candidates like ZX-XH2.54-4PZZ-Y are strong functional matches but require datasheet review to confirm exact pinout and dimensions.

Best replacement path

Use cross-vendor XH-series equivalents like Megastar ZX-XH2.54-4PZZ-Y or DEALON XH-4PS, after verifying mechanical drawings from datasheets.

Main risk

The primary risk is mechanical incompatibility from slight variations in housing dimensions or pin lengths across different manufacturers, even within the same 'XH' family.

Recommended alternatives

Strong functional match with identical pitch, position count, and electrical ratings. Requires mechanical verification.
