The JST B10B-PH-TW-S(LF)(SN) is a 10-position in-line plug from the PH series, with male pins on both ends — it functions as a wire-to-wire splice or adapter rather than a standard wire-to-board plug. The 2.00 mm pitch keeps the footprint compact for harness routing in tight enclosures. Free-hanging (in-line) mounting means it terminates a cable pair, not a PCB, so the harness builder treats it as a mid-line junction.
Why the 2.00 mm Pitch and 10 Positions Matter for Your BOM
The 0.079" (2.00 mm) pitch is the standard for JST PH-series connectors — it matches the mating receptacle housing and crimp terminal footprint. With 10 positions in a single row, this plug covers a 10-circuit harness branch without needing a wider dual-row layout. The pitch and position count together define the board-side footprint if you are adapting to a header; confirm the mating half uses the same 2.00 mm spacing before committing the BOM line.
