The 0.156" (3.96mm) pitch is wider than the common 0.100" IDC pitch, which means the mating header and board footprint must match this spacing exactly — a common gotcha when substituting from a 0.100" ribbon-cable system.
Termination and Contact Design
The feed-through feature and polarizing key prevent mis-mating with the header.
No official cross-reference or second-source is on record — the listed peer 1-1703095-1 is a different pitch (0.197" / 5.00mm) and connector type (blade socket), not a functional substitute.
