305-076-556-204

Edgeboard Connectors Overview

The EDAC Inc. 305-076-556-204 is a standard card edge connector from the 305 series, designed for dual female contact configurations with 76 positions. It features a 3.96 mm (0.156 inch) pitch and supports board thicknesses ranging from 1.37 mm to 1.78 mm. The connector utilizes copper alloy contacts with gold plating and thermoplastic polyester insulation. Rated for 5 A current, it operates within a temperature range of -40°C to +105°C and offers an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Dual row female contact configuration for reliable signal transmission
• Gold-plated copper alloy contacts ensure corrosion resistance and low contact resistance
• Thermoplastic polyester insulation provides stability across wide temperature ranges
• Panel mount design with flush mounting flange for secure mechanical installation

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects

Edgeboard Connectors Procurement Notes

Verify the exact part number against official EDAC documentation to confirm pin count and pitch specifications. Ensure compatibility with target PCB thickness limits before integration. Check RoHS compliance status via manufacturer datasheets. Confirm mounting style matches panel cutout dimensions. Validate operating temperature ratings against environmental conditions.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 76-position interface is required with a 3.96 mm pitch. Consider the vertical panel mount orientation and flush flange design for space-constrained enclosures. Evaluate the 5 A current rating against circuit load requirements. Assess the -40°C to +105°C operating range for environmental suitability.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which includes various position counts and mounting styles. The series is characterized by standardized dimensions and reliable performance in industrial applications. Similar parts in the series may differ in position count or flange features while maintaining consistent electrical characteristics.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series connectors with matching 76-position and 3.96 mm pitch specifications.
