Right-Angle Breakaway for Tight Board Edges
The tin post solders cleanly into a plated through-hole and the copper alloy contact body carries the rated 2 A per circuit without excessive temperature rise.
At 2.00 mm pitch, this header fits into a denser board layout than the older 2.54 mm standard — you save about 0.54 mm per row of routing channel. For a 3-position part that's not a huge saving, but in a multi-connector design the pitch choice cascades into the overall board width.
The key differences: 2842123-3 is unshrouded and push-pull, while 1-1871673-2 has a full 4-wall shroud and a locking latch — better for vibration resistance. The pitch is 2.00 mm vs 2.50 mm, so the board footprint is tighter on the 2842123-3. The mating finish is gold (15.0 µinch) on the 2842123-3 versus tin on the 1-1871673-2, which means the 2842123-3 will tolerate more mating cycles before wear. Both are active, both are UL94 V-0, but the 1-1871673-2 also carries a board lock for extra SMT reflow retention — the 2842123-3 relies on the solder joint alone.
