Board-Layout Fit: 2.00 mm Pitch, 3-Pin Breakaway
What 2 A and Gold Plating Tell You
Peer Comparison: 2.00 mm vs 2.50 mm Pitch
The closest functional alternative is the 1-1871673-2, a 4-position, dual-row, shrouded header on 2.50 mm pitch with tin-plated contacts and a board lock. That part adds a detent lock and 4-wall shroud for vibration resistance, but the pitch and circuit count differ — 2.00 mm vs 2.50 mm, 3 positions vs 4 positions. This 2842111-3 is unshrouded and push-pull, so it trades vibration security for a smaller footprint and lower profile.
