What it is
The Molex B7P-VH is a single-row, 7-position 0.156 inch (3.96 mm) pitch header in the VH series — a board-to-cable interconnect with a one-wall shroud that keys the mating direction and prevents stubbing the pins during assembly. Tin plating on both the mating face and the solder post means this is a general-purpose power/signal connector, not a high-cycle data connector. The brass contact material carries 10 A per circuit at the listed voltage of 250 V — sufficient for low-current bus power or control signalling in industrial equipment. The PA66 (Nylon 6/6) insulator is rated UL94 V-0 for flame resistance, and the operating window spans -25°C to 85°C — the range covers most unclimate-controlled industrial panel environments without special derating.
What the shroud and locking ramp mean for the fit
The single-wall shroud (Shrouded - 1 Wall) surrounds three sides of the contact array on the mating face, which gives directional alignment when the matching housing drops in from above. The locking ramp on the header body latches into the housing slot — once seated, it takes vibration and cable pull off the solder joints. For a board-to-cable harness, this matters more than it does for a floating board-mount. Mated stacking height is listed at 16.5 mm; the overall contact length is 0.575 inch (14.60 mm) with a post length of 0.146 inch (3.70 mm) below the insulator body. Confirm your PCB pad depth and any high-density routing below the component footprint.
RoHS status and what it means for sourcing
This part is Active in production but carries a RoHS non-compliant status. If your end product is headed for EU or China markets, this header will not clear the BOM compliance check without a variance or exemption. Flag it to your compliance team before specifying; it is otherwise a standard quoted-to-order line.
How it compares to the 8-position member
The only spec difference between the B7P-VH and the 8-position B8P-VH(LF)(SN) at this pitch is the circuit count — 7 against 8. All other ratings (10 A, 250 V, tin-plated brass, through-hole, locking ramp, UL94 V-0) are identical. If your panel wiring harness needs 8 positions at the same stack height and footprint class, the B8P-VH(LF)(SN) is the drop-in increase; if 7 is the exact circuit count, the B7P-VH is the fit without unused positions adding routing complexity.
