0.050-inch pitch board-to-board receptacle
The 5-104192-2: The 0.050" (1.27 mm) pitch sets the PCB footprint — tight enough for dense routing but still hand-solderable with a fine tip.
1 A signal-duty current ceiling
The current limit is well below the 3 A rating of some AMPMODU System 50 siblings (e.g., 1376775-2), so confirm your per-circuit load stays under 1 A before committing the BOM line.
Mated stack height options
This receptacle supports two mated stacking heights: 11.43 mm and 12.57 mm, depending on the mating header selected. The insulation height is 0.350" (8.89 mm), so the connector body itself takes up most of the z-height budget — plan your board spacing accordingly. In high-vibration environments, consider a secondary mechanical lock or adhesive.
