Board-Mount Fit and Routing
The SM20B-ZPDSS-TF(LF)(SN): This is a 20-position, 2-row header on 1.50 mm pitch — the footprint is tight enough for dense routing but leaves room for a via between pads on a standard 2-layer board.
This header mates with JST ZPD series crimp receptacles — the exact mating part number depends on the wire count and locking style.
