Footprint and Routing Fit
The 0.100" pitch sets the PCB footprint: a standard 0.025" square pin on a 2.54 mm grid.
Peer Comparison: 1-1871673-2
The key differences: 4 positions vs 3, dual-row vs single-row, shrouded vs unshrouded, and a board lock for SMT reflow retention. The 9-146274-0-03 is the simpler, lower-profile choice for a single-row signal run.
