305-076-521-258

Edgeboard Connectors Overview

The EDAC Inc. 305-076-521-258 is a standard card edge connector from the 305 series, designed for panel mount installation with a vertical orientation. It features 76 positions in a dual female configuration with a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts and solder pin termination. It supports board thicknesses ranging from 1.37 mm to 1.78 mm and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual female contact configuration for non-specified card edge applications
• Gold-plated copper alloy contacts ensure reliable electrical connection
• Vertical panel mount design with solder pin termination
• Thermoplastic polyester insulation provides structural stability

Edgeboard Connectors Applications

• Industrial control system interconnections

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and material specifications. Confirm that the required card edge board thickness falls within the specified 1.37 mm to 1.78 mm operational range. Ensure compatibility with the intended panel mounting hole dimensions and verify RoHS compliance status through current manufacturer declarations before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a high-density 76-position interface is required for vertical panel integration. The 3.96 mm pitch accommodates standard double-sided card edges. Consider the green thermoplastic polyester housing for environmental durability. Validate that the solder pin termination method aligns with the target PCB assembly process and that the operating temperature range meets the application's thermal requirements.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and configurations for diverse electronic interconnection needs. The 305-076-521-258 specifically addresses applications requiring robust dual-edge connectivity with standardized dimensional profiles for consistent mechanical fit across multiple system designs.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes with differing position counts or termination styles. Verify cross-compatibility with existing panel cutouts and mating card edge dimensions before substituting.
