Board layout and pin assignment
The 5-103414-7: The 9 positions, all loaded, match standard 9-conductor ribbon cable and IDC socket patterns.
The mating contact length of 0.240" (6.10mm) ensures full wipe before the shroud seats.
Comparing with peer headers
Peer 1376779-2 is a 3 A, gold-plated header with 8.00µin mating thickness — the thinner gold layer means fewer mating cycles before contact wear becomes a concern. 5-103414-7's 30.0µin gold provides a longer service life in high-cycle or corrosive environments.
