305-086-521-502

Edgeboard Connectors Overview

The EDAC Inc. 305-086-521-502 is a standard card edge connector receptacle featuring 86 positions with a 3.96 mm pitch and dual-row configuration. Designed for PCB mounting, it accepts boards with a nominal thickness of 1.57 mm. The contacts are gold-plated copper alloy, rated for 5 A current, and utilize solder termination. Operating temperature ranges from -40°C to +105°C, with insulation resistance specified at 5 GOhms.

Edgeboard Connectors Feature Summary

• Dual-edge contact design accommodates double-sided printed circuit boards for high-density interconnects.
• Gold-plated copper alloy contacts ensure reliable signal transmission and corrosion resistance.
• Thermoplastic housing provides structural integrity and electrical insulation for panel or PCB applications.

Edgeboard Connectors Applications

• Radar processing systems
• Digital oscilloscopes
• CMOS image sensor modules

Edgeboard Connectors Procurement Notes

Verify the specific suffix '502' against official EDAC documentation to confirm exact plating thickness and material specifications. Ensure compatibility with 1.57 mm board thickness before procurement. Cross-reference datasheet revisions to confirm compliance with current RoHS standards and environmental operating limits.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count (86 position) dual-row interface is required for thick PCBs. It is suitable for applications demanding robust mechanical retention and high-current capability within a compact form factor. Verify that the mating card edge geometry aligns with the 3.96 mm pitch specification.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various pin counts and row configurations designed for reliable board-to-board connections. The 305 series is characterized by its use of thermoplastic housings and gold-plated contacts, supporting both single and double-sided PCB integration in industrial environments.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include EDAC 305-086-500-201 and 305-086-520-501, provided they match the 86-position count and 3.96 mm pitch requirements. Verify that alternative headers or receptacles support the same 1.57 mm board thickness and current rating.
