Board-fit and mating reality
The B6B-ZR is a 6-position, single-row header on 1.50mm pitch, through-hole soldered, with a shrouded 4-wall housing and a detent lock for vibration-resistant mating.
Pitch and footprint constraints
The 1.50 mm pitch (0.059 in) drives a compact board footprint; the through-hole post length of 2.69 mm (0.106 in) and overall contact length of 6.50 mm (0.256 in) define the drill and solder profile. Mating contact length is 2.40 mm (0.094 in), which sets the wipe distance on the receptacle terminal.
RoHS non-compliant per the listing.
Peer comparison: position count and mounting
The B6B-ZR shares the same 1.50 mm pitch, 1 A rating, and detent lock as the 7-position B7B-ZR; the only difference is circuit count (6 vs 7). The surface-mount variant B6B-ZR-SM4-TF(LF)(SN) adds solder retention features and a 6.4 mm mated stack height versus 5.6 mm for the through-hole version.
