What this header is and where it sits in the VH series
The JST B6PS-VH(LF)(SN) is a 6-circuit, single-row right-angle through-hole header in the VH family, which fills the board-to-cable and panel-wiring interconnect space at 0.156 inch (3.96 mm) pitch. The shroud on the mating face is a single-wall construction that protects the contacts and provides keying orientation — the locking ramp on the housing side mechanically locks it into the matching receptacle so it cannot back out under harness pull or vibration.
What the ratings mean for your fit
How it compares to the same-series peers
The plain B6PS-VH carries the same 6 positions, 3.96 mm pitch, 10 A, 250 V, and tin-on-tin plating — the only difference is the absence of the (LF)(SN) lead-free finish suffix. If your BOM does not mandate RoHS or lead-free surface finish, the B6PS-VH is a direct drop-in on the same footprint. Both are Active.
