305-076-556-504

Edgeboard Connectors Overview

The EDAC Inc. 305-076-556-504 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 76 positions arranged in a dual-row configuration with a contact spacing of 0.156 inches (3.96 mm). The connector utilizes gold-plated copper alloy contacts and a solder pin termination type. It accommodates printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm) and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design for non-specified card types
• Gold-plated copper alloy contacts for reliable signal transmission
• Panel mount installation style with vertical orientation
• Thermoplastic insulation body with flush mount flange feature

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment board connections
• Automotive electronics module interfaces
• Test and measurement instrument internal wiring

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against official EDAC documentation to confirm exact plating thickness and material specifications. Ensure compatibility with target PCB thickness of 1.57mm before ordering. Confirm RoHS compliance status through current manufacturer declarations as regulatory requirements may evolve over time.

Edgeboard Connectors Selection Notes

Select this component when a high-density 76-position interface is required for vertical panel mounting. The 3.96mm pitch allows for substantial trace clearance compared to finer pitches. Consider the dual-edge configuration if both sides of the card require connection points simultaneously.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of edgeboard connectors, which are characterized by their low-profile insulator bodies and standardized .156 inch contact spacing. The series offers various position counts and termination options to suit different density and mechanical requirements in industrial and commercial electronic assemblies.

Edgeboard Connectors Replacement Considerations

Cross-reference with other 305-series variants such as 305-076-556-501 or 305-076-520-504 for potential substitutes. Verify that alternative parts match the 76-position count, 3.96mm pitch, and dual-edge female configuration to ensure mechanical and electrical interchangeability.
