Tin plating is cost-effective for moderate mating-cycle duty — the 78.7 µinch thickness provides a robust wear layer for occasional reconnects in field service or test fixtures, but it is not rated for the thousands of cycles a gold-plated contact would carry. The solder-tail length is 0.114\" (2.90 mm), suited for standard through-hole PCB thicknesses. ## Board Layout and Mating Fit In a vibration environment, the board-level solder joint takes the shear load, so the through-hole solder termination is the mechanical anchor. Mating header: any Dubox™ series pin header with 0.100\" pitch, 54 positions, dual-row configuration, and a mating pin length that accommodates the 11.04 mm stack height. RoHS compliance is indicated by the 'LF' suffix in the order code — lead-free. The housing material carries UL94 V-0 flammability rating.","metaTitle":"76342-427LF Amphenol ICC (FCI) Dubox™ 54-Position Dual-Row","metaDescription":"54-position dual-row receptacle, 0.100\" pitch, 11.04 mm stack height, tin plating.
