1.50 mm Pitch and the Board Footprint
The B8B-ZR(LF)(SN): The 1.50 mm pitch on this 8-position header sets the board footprint tighter than the 2.54 mm standard — it saves about 8 mm of board edge per row, which matters when routing traces between pads on a dense PCB.
1 A Current — Signal Duty, Not Power
The limiting factor is the tin-on-tin contact interface and the PA66 housing thermal ceiling — push it past 1 A and the temperature rise accelerates above the 85°C operating limit. The 50 V voltage rating matches the ZH series wire-to-board receptacle; it's adequate for low-voltage logic, sensor signals, and control lines in industrial or consumer equipment.
Detent Lock and Shroud — Vibration Resistance
The detent lock gives a positive click when the ZH receptacle is fully seated — you feel it through the harness. Mated stack height is 5.6 mm, which means the receptacle sits that far above the board surface — check your enclosure z-height budget before committing to the footprint.
Peer Comparison — Position Count Options
The B9B-ZR is the 9-position sibling in the same ZH series, same 1.50 mm pitch, same 5.6 mm stack height, same 1 A rating. The only difference is one extra circuit — if your BOM calls for 8 positions, this is the one; if you need 9, move to the B9B-ZR. The B8B-ZR-SM4-TF is a surface-mount variant of the same 8-position header, with solder retention tabs and a 6.4 mm stack height. If your assembly line is reflow-only, that's the pick; if you're hand-soldering or wave-soldering, the through-hole B8B-ZR(LF)(SN) is the simpler choice.
