What this 5-position receptacle is for
The 1241152-5: It is a surface-mount receptacle with a push-pull fastening type, and the pick-and-place feature means it can be handled by vacuum nozzles during automated assembly.
With 5 positions in a single row, the board footprint is narrow, leaving room for adjacent traces or components on dense boards.
Contact finish and reliability
The mating surface carries 31.5 µin of gold over copper alloy, which resists oxidation and keeps contact resistance stable across repeated mating cycles. The post finish is 100.0 µin tin, compatible with standard solder processes.
