305-078-500-568

Edgeboard Connectors Overview

The EDAC Inc. 305-078-500-568 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 78 positions with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Constructed with copper alloy contacts featuring gold plating, it provides reliable electrical performance. The unit utilizes a green thermoplastic insulator body and employs a solder pin termination method for secure mounting.

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 78-position configuration and 3.96 mm pitch before procurement. Confirm compliance with RoHS3 standards if environmental regulations apply to the assembly. Ensure the receiving facility has the capability to handle panel-mount headers requiring solder pin termination. Cross-reference the green insulator color and thermoplastic material against mechanical constraints in the final product design.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card interface with 78 contacts is required. The 3.96 mm spacing accommodates standard board layouts while maintaining signal integrity. The vertical panel mount style suits chassis-based installations where space efficiency is critical. Gold plating on copper alloy contacts offers durability for repeated mating cycles in industrial environments.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by robust construction suitable for demanding electronic applications. The 305-078-500-568 variant specifically addresses high-density connection needs through its 78-position layout. It represents a standardized solution for interfacing double-sided edge cards with host systems.

Edgeboard Connectors Replacement Considerations

Compatible substitutes within the same series include 305-070-556-568 and 305-080-555-568, which share identical 3.96 mm pitch and panel mount characteristics. Verify position count compatibility when substituting to ensure proper board alignment.
