The 215079-6: That pitch is a standard through-hole footprint — the board layout matches a wide range of existing header patterns without a custom keep-out. The forked contact geometry wipes the header pin on insertion, which keeps contact resistance stable over repeated mates.
Termination and mounting: through-hole with kinked pins
Termination is through-hole solder with kinked pins — the kink provides a press-fit retention force during wave soldering, holding the part in place before the solder solidifies. The contact post length is 0.122" (3.10 mm), which is typical for a single-sided PCB up to 1.6 mm thick; verify the board thickness against the post length to avoid bottom-side clearance issues.
Peer comparison: 12-position vs 6-position
The 215079-6 is through-hole only; if your board process is SMT-only, the 12-position surface-mount variant is a functional alternative for higher-density layouts, though the position count doubles.
