Right-angle 14-position header with friction lock and board lock
The 1-1744426-4: This is a 14-position, single-row, right-angle header from TE's Economy Power 2.5 series, pitched at 0.098" (2.50 mm). It's shrouded on all four walls, so the receptacle can't be misaligned during mating — a common field failure when the plug is pushed on at an angle and bends a pin.
2.50 mm pitch — wider than the 2.00 mm CT series, more room per trace
That extra 0.50 mm per channel means you can run a thicker trace or fit a via between pads on a standard 1 oz copper board without necking down. The 14-position single-row layout loads all positions, so every pin is present — no blank spots to confuse a harness build.
