The BM04B-XASS-TF(LF)(SN) is the 4-circuit member of JST's XA series board-to-cable/wire header line, a shrouded 4-wall surface-mount header with a locking ramp for positive retention. The nylon housing is rated UL94 V-0.
The mating pitch is 0.098" (2.50mm). This is the same pitch as the entire XA series, so the header mates only with 2.50mm-pitch XA crimp housings.
Surface mount.
The closest functional sibling is BM05B-XASS-TF(LF)(SN), which is identical except for 5 positions instead of 4. Both share the same 2.50mm pitch, tin plating, 3 A rating, and SMD mounting. The 3-position BM03B-XASS-TF(LF)(SN) is also a direct drop-in for lower circuit counts.
