The single-row, 3-position layout is fully loaded — all three positions are populated. The header is through-hole with kinked pins for solder retention, and the post length of 0.126" (3.20 mm) is long enough for a standard 1.6 mm PCB with a solder fillet on the bottom side.
Mating and Retention: Detent Lock and 3-Wall Shroud
For a typical 22 AWG wire in the CT series, the contact is rated around 2-3 A; always verify the derating with the actual wire gauge and ambient temperature.
How This Header Differs from a Right-Angle 11-Position Sibling
The closest peer in the same CT series is 1-292164-1: same 2.00 mm pitch, same detent lock, same tin-plated contacts and UL94 V-0 housing, but it carries 11 positions in a right-angle, through-hole orientation with a 4-wall shroud. If your board layout needs a right-angle exit or more than 3 circuits, that sibling is the direct swap — but for a vertical, 3-position, board-to-cable connection, this 292161-3 is the correct member.
