How this header compares to a shrouded alternative
The unshrouded 9-146308-0 exposes all 80 pins for direct mating with a receptacle. By contrast, the shrouded 1-1871673-2 (4-position, 0.098" pitch) uses a 4-wall shroud and detent lock for vibration resistance — but it carries only 4 circuits and uses tin-plated contacts. For a high-density 80-position board-to-board link, the 9-146308-0 is the correct choice; the shrouded sibling serves a different, lower-density application.
