40 Positions on 0.100" Pitch — Footprint Fit
The breakaway design means the 40-position strip can be snapped into shorter lengths, though this part ships fully populated (all 40 positions loaded). For a fixed 40-circuit interconnect, there is no need to break it.
Tin Plating at 118.1 µinch — Mating Cycle Budget
The mating contact finish is tin, 118.1 µinch (3.00 µm) thick — a robust layer for cost-sensitive applications. Tin is rated for roughly 50–100 mating cycles before fretting corrosion becomes a concern in vibration environments. For a connector that is mated once during assembly and rarely touched again, this is a practical choice. Compare with gold-plated siblings in the C-Grid III family: gold carries a higher per-unit cost but extends mating cycle life to 500+ cycles. If your application requires frequent board swaps or field-service reconnects, a gold-plated version is worth the premium.
It is ROHS3 compliant, meeting current EU restriction requirements for lead and other substances. No stock-holding claim — quoted per RFQ.
