The 2355179-4: 4 positions at 2.00mm pitch — that footprint fits a compact board edge or mezzanine stack where every millimetre of board real estate is budgeted.
Board Fit and Termination Checklist
Through-hole solder termination, unshrouded push-pull fastening — mates with any standard 2.00mm pitch receptacle. The 0.110" (2.79mm) post length and 0.157" (4.00mm) mating length give enough standoff for cleaning flux residue under the header after wave solder. Pick-and-place compatible (vacuum pickup area on top of the header body) — the tube packaging feeds into automated assembly without tray changeover.
