The mated stacking height of 10.81mm defines the z-height budget for mezzanine card spacing; the push-pull fastening type allows tool-less mating and unmating in confined enclosures. ## Contact Plating and Housing Material Tin plating is suited for moderate mating-cycle applications (typically 50–100 cycles) in controlled environments; for higher reconnect duty or corrosive atmospheres, a gold-plated sibling in the Dubox series would be the appropriate choice. The gray insulation color aids visual identification during board inspection. The connector is a female socket with square contact shape, configured for bottom or top entry — meaning the same part can be used on either side of a board-to-board stack, simplifying inventory. Termination is solder to surface-mount pads. All 20 positions are loaded; the package is tube for automated pick-and-place.","metaTitle":"91618-410LF Dubox 20-Pin SMT Receptacle, Board Lock","metaDescription":"Amphenol ICC (FCI) Dubox 91618-410LF: 20-position, 2-row SMT receptacle, 0.100\" pitch, board lock, UL94 V-0.
