What it is and where the VH series sits
The JST B7P-VH(LF)(SN) is the 7-circuit member of the VH family — a single-row board-to-cable header with a 1-wall shroud and a locking ramp that mechanically latches into the matching VH plug housing to resist vibration-assisted decoupling. The series targets power-distribution and signal-harness applications in industrial equipment where a positively-latching wire-connector interface outranks the density of a bare unshrouded pin strip.
Ratings that govern the BOM fit
At 10 A per contact and 250 V the B7P-VH(LF)(SN) covers low-level power taps such as actuator feeds and LED drivers without requiring a dedicated power connector. The 0.156 inch (3.96 mm) pitch provides wider spacing that reduces flashover risk at 250 V and gives fingers more room during in-field termination. Tin plating on both the mating face and the solder post is standard for this series — no gold option is listed on this member. For high-cycle reconnection duty the tin finish will oxidize faster than gold, but for permanent or low-cycle harness installs (the typical board-to-cable use case) the plating grade is adequate. Brass substrate carries the current without the magnetic permeability concerns of steel under high current pulses.
Shrouding and locking ramp
The single-wall shroud guides the plug housing into the header and the locking ramp snaps the pair together — the audible click confirms the latch is seated before the harness ships. Without the shroud a pin strip is fully exposed; with it the VH header survives the cable-pull loads and incidental side-loading that would back a bare header out of the PCB hole.
Board-level fit
Through-hole mounting with a 0.146 inch (3.70 mm) post length and 0.575 inch (14.60 mm) overall contact length gives reasonable stand-off above the board for cleaning under the header after wave solder. The 0.370 inch (9.40 mm) insulation height and 16.5 mm mated stacking height define the header's z-profile in the assembly — relevant if the enclosure or daughter-card cage constrains the header envelope. The housing material is polyamide (PA66) rated UL94 V-0, so the connector can be specified inside equipment that requires flame-retardant enclosure plastics.
Lifecycle and sourcing posture
The B7P-VH(LF)(SN) carries an Active product status and RoHS Compliant designation — no end-of-life notice, no last-time-buy date, and no official successor is listed. The non-lead-free twin B7P-VH shares the same 7-position footprint, pitch, current, and voltage ratings and drops into the same PCB land pattern; the only difference is the lead-free plating code in the order string.
