What this header is and where it sits in the VH series
The JST S7P-VH is a 7-position single-row member of the VH family — a 3.96 mm pitch board-to-cable header series built around a shrouded 1-wall body and a locking ramp that secures the mating housing against vibration. Right-angle through-hole termination routes the connector parallel to the board surface for edge-mount power or signal distribution in appliances and industrial controls.
What the ratings mean for your BOM line
10 A per circuit at 250 V is the headline rating — and for the VH series it is a genuine per-contact ceiling, not a thermal derate of a lower figure. Tin plating on BOTH the mating interface and the solder tail sets the cycle life well below what a gold-plated equivalent would survive: the locking ramp handles mechanical retention, but the tin contact interface is the life-limiting factor if the assembly sees repeated mating. The 0.335-inch (8.51 mm) insulation height defines the mated stack dimension on the board side — relevant for z-height budget in dense layouts. Operating temperature runs from -25°C to 85°C, which covers the thermal envelope of most enclosed-panel and appliance applications.
Will S7P-VH(LF)(SN) drop in without reworking the panel?
Yes — the S7P-VH(LF)(SN) carries the same position count (7), the same 3.96 mm pitch, the same right-angle through-hole footprint, and the same shroud geometry. The only functional difference is plating: the (LF)(SN) variant substitutes lead-free surface finish for the standard tin, which is the RoHS-compliant path for new designs. Pitch, pinout, and mounting hole pattern are identical, so it drops into the same panel cutout and mates with the same VH housings. If your board is already laid for the S7P-VH, the (LF)(SN) is a form-fit-function second source — not a redesign.
