The 2-644487-5 is a 5-position single-row header from the MTA-100 series, pitched at 0.100" (2.54mm) — the standard spacing for ribbon cable and IDC mass-termination receptacles. The shrouded 4-wall housing with a friction lock keeps the mated pair from backing off under cable tug or moderate vibration, which is the main reason to pick this over an unshrouded pin strip. The post tails are tin-plated for a reliable solder joint in the through-hole board.

This is a single-row, 5-position header with all positions loaded. The contact layout follows the standard 0.100" pitch grid; pin 1 is typically marked by a square pad or chamfer on the housing. Refer to the TE MTA-100 product drawing for the exact footprint.
