The 8-338069-4: The 14 circuits are fully loaded, so every pin position is active.
Surface-mount termination with pick-and-place capability
The connector is surface-mount with solder termination, and it includes pick-and-place features for automated assembly.
Peer alternatives for comparison
If your design needs fewer circuits, that part is a drop-in candidate. For higher cycle life, consider 1376775-2 (5-position) or 1376775-3 (3-position) — both use gold-plated contacts and a different housing material (thermoplastic, polyester, glass filled), but they are not pin-compatible with the 14-position layout.
