Product details

54-Position Dual-Row Dubox™ Receptacle

The 76342-427LF is a 54-position, dual-row board-to-board receptacle from the Dubox™ series by Amphenol ICC (FCI). 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.

Frequently asked questions

What is the exact pin count of 76342-427LF?

54 positions, all loaded, in a dual-row configuration.

What is the mating header for 76342-427LF?

Any Dubox™ series 0.100" pitch, 54-position, dual-row pin header with a mating pin length that supports the 11.04 mm stack height. The receptacle's base number is 76342; the header base number is typically in the 68000 or 77311 series. Confirm the header's pin length against the receptacle's 0.275" insulation height for full contact wipe.
