This header mates with JST XA series crimp housings that accept the appropriate crimp terminals.
The XA series SMT shrouded headers are available in 4-position (BM04B-XASS-TF(LF)(SN)) and 6-position (BM06B-XASS-TF(LF)(SN)) variants, all sharing the same 2.50mm pitch, 11.9mm stack height, and locking ramp feature. The 5-position BM05B-XASS-TF sits between them for applications requiring an odd circuit count.
No, the BM05B-XASS-TF is listed as RoHS non-compliant. For RoHS-compliant requirements, order the alternate BM05B-XASS-TF(LF)(SN), which is the direct lead-free equivalent.
The mating pitch is 0.098" (2.50mm), which sets the PCB footprint spacing between adjacent pins.
Yes, the fastening type is a locking ramp that provides positive retention with the mating housing, reducing the risk of accidental disconnect under vibration.
