305-084-521-202

Edgeboard Connectors Overview

The EDAC Inc. 305-084-521-202 is a standard card edge connector from the 305 series, designed for vertical panel mounting applications. It features a dual-row configuration with 84 positions and a contact spacing of 3.96 mm (0.156 inches). The connector utilizes gold-plated copper alloy contacts with PC tail termination for secure soldering. It is rated for 5 A current and operates within a temperature range of -40°C to +105°C. The housing is constructed from green thermoplastic material, providing insulation resistance of 5 GOhms and compatibility with board thicknesses of 1.57 mm.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design supporting high-density signal routing across two rows
• Gold-plated contacts ensure reliable conductivity and corrosion resistance in demanding environments
• Vertical panel mount style facilitates structured integration into chassis or enclosure systems
• Thermoplastic housing provides mechanical stability and electrical insulation properties

Edgeboard Connectors Applications

• Industrial control system interconnects requiring robust panel-mounted connections
• Telecommunications equipment backplanes utilizing standard card edge interfaces
• Test and measurement instrumentation boards needing high-position count connectors
• Automotive electronic modules requiring durable vertical mounting solutions

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 84-position dual-row configuration before ordering. Confirm that the PCB design accommodates the 3.96 mm pitch and 1.57 mm board thickness specifications. Ensure that the manufacturing facility handles gold-plated components appropriately to maintain contact integrity. Check local regulatory compliance requirements regarding RoHS standards for the intended market. Validate that the vertical panel mount orientation aligns with the mechanical assembly constraints of the final product design.

Edgeboard Connectors Selection Notes

Select this component when a high-count, dual-row interface is necessary for vertical panel installation. Consider the 3.96 mm pitch requirement against available PCB layout space and trace routing capabilities. Evaluate the thermal operating range to ensure suitability for the expected environmental conditions. Assess the mechanical strength provided by the thermoplastic housing against vibration and shock requirements. Compare the gold plating specification against cost-sensitive alternatives if extreme durability is not critical.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which specializes in standard card edge solutions. The series offers various position counts while maintaining consistent 3.96 mm pitch dimensions. The 305-084-521-202 represents a high-density variant within this lineup, catering to applications requiring extensive I/O connections. Similar parts in the series differ primarily in position count and specific termination styles, sharing common electrical ratings and mounting characteristics.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series connectors with equivalent position counts and pitch specifications. Verify that any alternative maintains the same dual-row female configuration and vertical mounting orientation. Ensure that replacement parts match the gold plating and thermoplastic housing materials for identical performance characteristics.
