HCTL
Strong form-fit-function match from the same manufacturer with identical key electrical and mechanical specs.
Finding a substitute for the HCTL XH-2A-R, a 2-pin 2.5mm pitch through-hole header, involves matching key electrical and mechanical specs. Several alternatives exist, including options from the same manufacturer and other vendors, with minor variations to consider.
Many alternatives match the 3A/250V rating.
Requires verification of datasheet mechanical drawings to confirm exact footprint and height.
This is a common connector type with multiple sources.
Yes, several direct replacements for the XH-2A-R exist. HCTL's XHB-2A-R and DEALON's XH-2PS are strong form-fit-function candidates with matching pitch, pin count, and electrical ratings.
The best path is to use other parts from HCTL's XHB series, like XHB-2A-R, which share identical core specifications and are likely pin-compatible.
The main risk is mechanical incompatibility. Ensure the substitute's pitch (2.5mm) and footprint dimensions precisely match the original part to avoid assembly issues.
