1.50 mm pitch, 5-position SMT header — board-fit and routing
The 5-1775443-5: This is a single-row, 5-position header from TE's High Performance Interconnect (HPI) series, pitched at 1.50 mm. The 5.00 mm insulation height gives room for the shroud walls to guide the mating receptacle without side-loading the solder joints.
For a signal-level interconnect in a harness that sees occasional disconnect, this is a cost-effective choice. That temperature span covers most automotive cabin and industrial enclosure environments — the housing won't soften or become brittle across seasonal thermal cycling.
Mating half and application fit
The Board to Cable/Wire style means it connects a wire harness to the PCB, typical in automotive, general-purpose, industrial, and medical equipment where a reliable but serviceable interconnect is needed.
