50-Position Density and Board Fit
The 3-1761603-5: This AMP-Latch header packs 50 positions in a dual-row 2.54 mm pitch layout — the board footprint is 25.4 mm wide across the rows, and the 0.350-inch (8.89 mm) insulation height leaves room for cable strain relief above the connector body.
Shrouded Housing and Keying for Harness Assembly
The keying slot ensures the mating cable connector cannot be inserted backwards or misaligned.
Comparing to a Higher-Current Sibling
The 3-1761603-5 at 50 positions and 1 A per contact is suited for dense signal interconnect, not high-current bus work.
