The BM08B-SRSS-TB: The 0.039" (1.00 mm) pitch sets the PCB footprint for this 8-position header — the trace escape between pads is tight enough that a single via between adjacent pins is impractical; route one trace per channel on the outer layer and drop vias to inner layers for the remaining signals. Mated stack height is 4.9 mm, which means the board-to-board clearance in the enclosure must allow for the header plus the mating receptacle height — the 4.9 mm is the assembled height, not the header alone.

Frequently asked questions
Is BM08B-SRSS-TB compatible with the JST SR series receptacles?
Yes — the BM08B-SRSS-TB is a header in the SH/SR series and mates with SR-series crimp receptacles (such as the SR-08 series) at the same 1.00 mm pitch. Confirm the receptacle's position count matches 8 positions.
