5-position unshrouded header for board-to-cable harnesses
The 640453-5 is a right-angle, through-hole pin header from TE's MTA-100 series, carrying 5 circuits on a single row at 0.100" (2.54mm) pitch. The square, tin-plated copper alloy pins extend 0.295" (7.49mm) from the insulator for mating, with a 0.140" (3.56mm) solder post for through-hole termination.
Pitch, orientation, and post length for board fit
At 0.100" pitch, the 5-position header occupies 0.500" of board edge. The insulation height between rows is 0.100" (2.54mm), matching the pitch for consistent pin spacing.
Tin contact finish and current rating context
The housing material is thermoplastic with UL94 V-0, so the connector meets the flame-retardant requirement for power supplies, control panels, and telecom gear.
