What this 13-position shrouded header is built for
The 1-440054-3 is a single-row, 13-position header from TE's High Performance Interconnect (HPI) series, pitched at 2.00 mm — a common spacing for board-to-cable/wire connections in automotive, industrial, and medical equipment. It is a shrouded 4-wall header, meaning the plastic housing surrounds the male pins on all sides, protecting them from accidental shorting and guiding the mating receptacle into alignment.
Termination and mounting — press-fit or solder
The termination is listed as press-fit and solder, which means the contact posts can be pressed into plated through-holes without solder (press-fit) or soldered conventionally — a flexibility that matters when you're mixing assembly methods on the same board. Mounting is through-hole only; the header is not surface-mount, so the board layout needs plated holes at the 2.00 mm pitch.
Contact plating and material choices
It is also a single-row, shrouded header at 2.00 mm pitch, but with 11 positions instead of 13, and a right-angle orientation rather than vertical. If your design requires the full 13 positions and 250 V rating, the 1-440054-3 is the correct choice. For a right-angle board exit with fewer circuits, the 1-292164-1 is a viable alternative.
