The 1734829-4: Its defining feature is the 0.049" (1.25 mm) pitch — the tightest in the HPI family — which drives the PCB footprint and limits the per-contact current to 1 A.
With a 0.126" (3.20 mm) insulation height and a 0.091" (2.30 mm) post length, this header sits low on the board.
The 1734829-4 is sourced through independent distribution.
The mating pitch is 0.049" (1.25 mm).
Yes, it is a shrouded 4-wall header.
