Peer Comparison: Shrouded vs Unshrouded
The closest functional alternative is the shrouded 1-1871673-2 (4 positions, 2.50 mm pitch, tin-plated, board lock). The 2842128-5 is unshrouded — no alignment wall, no keying, no detent lock — which saves board space but trades vibration resistance. For a board-edge stack where the receptacle is guided by the housing, the shrouded peer adds mechanical security; for a low-profile mezzanine where z-height is tight, the unshrouded breakaway style is the right call.
