Product details

17-position MTA-100 header with friction lock

The 1-640456-7: This is a single-row, 17-position header from the MTA-100 series, pitched at 0.100" (2.54mm) — the same spacing as legacy 0.100-inch ribbon cable and many IDC connectors. The 1-wall shroud guides the mating housing straight on, and the friction lock keeps it latched under vibration without a secondary clip.

The through-hole termination has a post length of 0.140" (3.56mm) — enough for a standard 1.6mm PCB with good solder fillet. Overall contact length is 0.535" (13.59mm), so the mated stack height sits around the 0.300" mark. Single row keeps the board footprint narrow.
