At 0.156" pitch, the 2-position header occupies a compact footprint — the contact length on the mating side is 0.400" (10.16mm), and the post length is 0.175" (4.45mm) for through-hole soldering.
The 3-644754-2 has a 0.156" (3.96mm) pitch, single-row, 2 positions.
Yes, it is a right-angle through-hole header, with the pins exiting perpendicular to the PCB.
It has a single-wall shroud that guides the mating receptacle and protects the pins during handling.
The current rating varies by wire gauge used in the mating terminal — the header itself is rated for the full MTA-156 current capacity, which depends on the crimp contact and wire size.
