3-Position 2 mm Header for Wire-to-Board
The B03B-PNISK-1A is a 3-position, single-row header from JST's PNI series, designed for board-to-cable/wire connections. Its 2.00 mm pitch sets the PCB footprint and the per-contact current ceiling — at 3 A the temperature rise stays within the PA66 housing limit. The shrouded 4-wall design with a latch lock provides vibration-resistant mating without a secondary lock, suited for equipment where the cable is routed near moving parts.
Board Fit and Termination
Through-hole mounting with press-fit, solder termination — the press-fit tail holds the header in place during wave solder, eliminating the need for a secondary hold-down. The 0.134" (3.40 mm) post length provides enough stand-off for cleaning under the header. Mated stacking height is 12.25 mm, which sets the z-height budget for the enclosure — confirm this clears any components on the board opposite the header.
