What it is and where it sits in the VH series
The B9PS-VH is a 9-circuit single-row header in JST's VH series — a board-to-cable power connector class that runs at 3.96 mm pitch. The "S" in the suffix denotes right-angle (side-entry) through-hole mounting, which differentiates it from the straight vertical-mount B9P-VH-B sibling. Each position carries a square male pin that mates with the matching VH female housing and its tin-plated contact beam. The one-wall shroud and locking ramp keep the housing seated under harness flex — no secondary latch needed to hold the pair in the field.
What the ratings mean for the fit
Lifecycle and sourcing posture
B9PS-VH is Active in production. The one flag that needs attention: it carries RoHS non-compliant status. If the build is headed for the EU market or any supply chain with RoHS enforcement, this part will need a formal waiver or a search for the lead-free-plated variant in the same series.
