333-076-521-808

Edgeboard Connectors Overview

The EDAC Inc. 333-076-521-808 is a dual female card edge connector designed for through-hole mounting and solder termination. It features 76 positions arranged in two rows with a 0.156-inch (3.96 mm) spacing. The contacts are made of copper alloy with a gold plating thickness of 10.0 µin (0.25 µm). The insulator is constructed from thermoplastic polyester, providing a green color finish. It supports board thicknesses between 0.054 and 0.070 inches (1.37 to 1.78 mm) and operates within a temperature range of -40°C to 105°C.

Edgeboard Connectors Feature Summary

• Dual female contact configuration with cantilever spring design for secure board retention
• Gold-plated copper alloy contacts ensure reliable signal transmission and corrosion resistance
• Thermoplastic polyester insulation offers stability across a wide operating temperature range

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connections
• Communication equipment utilizing standard card edge interfaces
• Consumer electronics assemblies needing high-reliability interconnects

Edgeboard Connectors Procurement Notes

Verify the specific part number against official EDAC documentation to confirm current availability and manufacturing status. Ensure that the required board thickness falls within the specified tolerance of 0.054 to 0.070 inches. Confirm that the application environment remains within the rated temperature limits of -40°C to 105°C to maintain connector integrity and performance standards.

Edgeboard Connectors Selection Notes

Select this component when a dual-row female connector with a 0.156-inch pitch is required for through-hole assembly. The choice is appropriate for designs necessitating cantilever contacts and gold-plated terminals. Consider the thermoplastic polyester insulation properties for environmental stability. Verify compatibility with the target printed circuit board dimensions and mounting requirements before integration.

Edgeboard Connectors Part Context
