The 640453-2 is a 2-position, single-row, unshrouded header from TE's MTA-100 series.
The 0.295" (7.49mm) mating pin length provides good wipe in a standard MTA-100 receptacle. The 0.140" (3.56mm) solder tail length suits a standard 1.6mm-thick PCB.
It is an unshrouded header — the male pins are exposed. The mating receptacle must provide the alignment and polarization.
No direct pin-compatible replacement or equivalent is listed by the manufacturer. The 640453-2 is the current active part number for a 2-position, 0.100" pitch, right-angle, unshrouded header in the MTA-100 series.
