Locking and compliance for production environments
Cross-shop against a dual-row sibling
The closest functional second-source in the same series is the 1-1871673-2, also a 4-position right-angle header at the same 0.098" pitch, but it is a dual-row version with a detent lock instead of a friction lock, and its contacts are square rather than circular. If your application needs more positions or a different locking style, the 1-1871673-2 is a direct mate alternative — though the dual-row format changes the board footprint.
