Board footprint and routing fit
The 1-1775470-4: This is a 14-position, single-row header on 2.00 mm pitch — the footprint takes 28 mm of board edge for the pin row, plus clearance for the 4-wall shroud.
Mating half and harness side
This is a Board to Cable/Wire header — it mates with a matching 2.00 mm pitch receptacle housing (TE HPI series, 14-position, single-row). The 4-wall shroud guides the plug and protects the square pins from bending during blind mating. Contact mating length is 0.138 in (3.50 mm), which provides enough wipe for a reliable tin-to-tin connection.
