4-position right-angle header for wire-to-board
Board lock and friction lock for vibration resistance
The friction lock on the mating interface provides a positive tactile engagement — it won't rattle loose in a lightly shaken enclosure, but it's not a high-retention latch for heavy cable pulls.

The 1-1871673-2 is a dual-row, 4-position header in the same Economy Power 2.5 series, with a detent lock instead of friction lock, and square pins versus circular. Both share the 2.50mm pitch and tin plating, but the dual-row version adds a second row at 3.30mm spacing and uses a box package.
