305-084-556-578

Edgeboard Connectors Overview

The EDAC Inc. 305-084-556-578 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 84 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). It utilizes gold-plated copper alloy contacts housed in a green thermoplastic insulator body. The component supports panel mounting in a vertical orientation and employs solder pin termination for secure electrical connection.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact plating, housing color, and termination type match project requirements. Ensure the selected variant aligns with the required PCB thickness and mounting orientation. Cross-reference the manufacturer datasheet for precise dimensional tolerances and environmental operating limits before finalizing procurement specifications.

Edgeboard Connectors Selection Notes

Select this connector when a high-pin-count interface is required for dual-edge cards. The 3.96 mm pitch accommodates larger gauge traces compared to finer pitches. Verify that the application environment stays within the specified temperature range. Confirm that the panel mounting style fits the mechanical enclosure constraints and that the solder pin termination method matches the assembly process capabilities.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of card edge connectors, which offers various position counts and mounting options. The series is characterized by its robust construction and standardized dimensions, facilitating interchangeability within compatible systems. The 305 series serves as a foundational solution for connecting edge-board modules to main chassis infrastructure in demanding industrial and commercial environments.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series variants with matching 84-position counts and 3.96 mm pitch. Ensure any replacement maintains the same dual-row configuration and vertical panel mounting style. Verify that alternative part numbers support the identical 1.57 mm PCB thickness requirement and utilize compatible solder pin termination methods for direct integration.
