306-021-421-168

Edgeboard Connectors Overview

The EDAC Inc. 306-021-421-168 is a dual-edge card edge connector receptacle featuring 42 positions with a 0.156-inch (3.96 mm) pitch. Designed for non-specified dual-edge boards, it accommodates card thicknesses ranging from 0.054 to 0.070 inches (1.37 to 1.78 mm). The component utilizes gold-plated copper alloy contacts and a green thermoplastic polyester housing. It supports a current rating of 5 A and employs solder pin termination for secure panel mounting.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to confirm exact pin count, pitch, and termination style. Ensure compatibility with the target PCB card thickness range of 1.37 mm to 1.78 mm. Confirm that the dual-edge receptacle design aligns with the mechanical constraints of the assembly. Cross-reference the manufacturer part number directly with authorized distributors to avoid counterfeit components.

Edgeboard Connectors Selection Notes

Select this component when a high-density dual-edge connection is required for industrial applications. The 42-position layout suits systems needing substantial signal or power routing within a compact footprint. Verify that the 0.156-inch pitch matches the mating card edge specifications. Consider the green housing color for visual identification if required by the assembly process. Ensure the 5 A current rating meets the electrical load requirements of the circuit.
