AI replacement insight
Electrical risklow
Key ratings (3A, 250V) are matched by many alternatives.
Package riskmedium
Requires datasheet check of footprint and dimensions to ensure PCB and mating compatibility.
Can it be replaced directly?
No drop-in replacement is verified without a mechanical drawing comparison. However, several candidates like XH-2PS from DEALON offer identical electrical specifications and are likely compatible.
Best replacement path
Use a cross-vendor XH-series compatible part like XH-2PS after verifying its datasheet for mechanical fit.
Main risk
Mechanical incompatibility, including footprint, height, and shroud dimensions.
