HCTL
Strong alternative from the same manufacturer with matching key electrical and mechanical specifications.
HC-XA-3A is a common 3-pin, 2.5mm pitch straight header. Several form-fit-function alternatives exist from manufacturers like HCTL, DEALON, and Megastar, offering compatible electrical ratings and mounting styles. Verifying detailed mechanical dimensions is recommended before substitution.
While pitch and pin count match, housing dimensions (height, width) must be verified from datasheets.
Multiple candidates match the 3A/250V rating.
This is a common connector type with many manufacturers and high availability.
Yes, several potential direct replacements for HC-XA-3A exist, such as HCTL's own XH-3A-P. These share the same 3-pin, 2.5mm pitch, through-hole format and electrical ratings. A final check of mechanical drawings is necessary to confirm 100% compatibility.
Start with HCTL XH-3A-P as it's from the same manufacturer, then evaluate other XH-series clones like DEALON XH-D-3A.
Minor differences in housing dimensions could cause interference with other components or the mating connector.
