The 6-103168-1: Pitch is 0.100" (2.54mm) on both the row and column spacing — a standard footprint that matches a wide range of IDC receptacles and crimp housings in the AMPMODU family.
Fit and Retention — What the Shroud and Lock Mean on the Bench
The 4-wall shroud (0.440" / 11.18mm insulation height) surrounds the pins completely, so the header can be handled and shipped without bending pins — a real time-saver on the assembly line.
Sourcing and Lifecycle — Still in Active Production
Production is ongoing.
Main difference: 26 circuits vs 4, 2.54mm vs 2.50mm pitch, and gold vs tin on the mating face — the 6-103168-1 carries more positions and better corrosion/cycle-life margin.
