AI replacement insight
Package riskmedium
Many candidates are from different series (XH), requiring mating part verification.
Electrical risklow
Key electrical ratings (3A, 250V) are consistent across viable candidates.
Can it be replaced directly?
Yes, HCTL HC-XHB-3A is a likely direct replacement, but requires datasheet verification of its mechanical drawing against your PCB layout.
Best replacement path
The most promising path is HCTL HC-XHB-3A, which appears to be a direct dimensional clone. For a same-brand option, CJT A2508WV-3P is very close but has minor height/pin length differences.
Main risk
The primary risk is ensuring the substitute's housing is compatible with the intended mating connector, as different series (e.g., XH vs. A2505) may not be interchangeable despite having the same pitch and pinout.
