Tin plating on the solder tails keeps the board-side termination cost-effective.
This header mates with Milli-Grid 87831 series crimp receptacles and IDC sockets — both 40-position, 2.00mm pitch, 2-row. Through-hole mounting with 0.098" (2.50mm) post length and 0.141" (3.60mm) mating pin length. The 2.00mm row spacing matches the pitch, keeping the board footprint compact — a 40-position header occupies roughly 20mm × 8mm of board area including the shroud walls.
The mating half is a Milli-Grid 87831 series 40-position, 2-row, 2.00mm pitch receptacle — either a crimp housing or an IDC socket, both with the matching latch feature. The exact order code depends on termination type (crimp vs IDC) and wire gauge.
