305-076-556-512

Edgeboard Connectors Overview

The EDAC Inc. 305-076-556-512 is a standard card edge connector header featuring 76 positions with a 3.96 mm (0.156 inch) pitch. Designed for dual-edge card insertion, it utilizes gold-plated copper alloy contacts to ensure reliable signal transmission. The component supports a 1.57 mm board thickness and operates within a temperature range of -40°C to +105°C. It employs a vertical panel mount style with solder pin termination, offering a robust mechanical interface for high-density electronic applications requiring durable connectivity.

Edgeboard Connectors Feature Summary

• Dual-edge female contact configuration for secure card retention
• Gold-plated copper alloy contacts for corrosion resistance
• Vertical panel mount design for space-efficient integration

Edgeboard Connectors Applications

• Industrial control systems
• Telecommunications equipment
• Automotive electronics modules

Edgeboard Connectors Procurement Notes

Verify the complete part number including suffixes to confirm specific plating thickness and material certifications. Ensure compatibility with the target PCB edge card dimensions, particularly the 1.57 mm thickness specification. Confirm that the vertical mounting orientation aligns with the system enclosure requirements before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this connector when a high-pin-count interface with a 3.96 mm pitch is required. The dual-edge design provides superior mechanical stability compared to single-edge variants. Verify that the operating environment stays within the specified thermal limits and that the panel mount style fits the available chassis space constraints.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and pitch options to accommodate different density requirements. The 305 series is characterized by its thermoplastic housing and reliable solder pin termination, widely used in modular electronic assemblies.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series headers with identical 76-position count and 3.96 mm pitch. Cross-manufacturer replacements must match the dual-edge female contact geometry and panel mount orientation to ensure functional interchangeability.
