305-086-521-507

Edgeboard Connectors Overview

The EDAC 305-086-521-507 is a standard card edge connector receptacle featuring 86 positions arranged in a dual row configuration. It utilizes a 3.96 mm (0.156 inch) pitch and is designed for PCB mount installation with a straight orientation. The contacts are gold-plated copper alloy, supporting a continuous current rating of 5 A. The housing is green thermoplastic, compatible with board thicknesses between 1.37 mm and 1.78 mm. Operating temperatures range from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure alignment
• Provides 1800VACrms dielectric voltage strength
• Features flush mount flange with top opening and M3 threaded inserts

Edgeboard Connectors Applications

• High-density electronic interconnect systems
• Industrial control panel connections
• Telecommunications equipment backplanes

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official catalog to ensure correct contact plating thickness and flange configuration. Confirm that the application environment remains within the specified -40°C to +105°C operating temperature range. Check for RoHS3 compliance requirements if applicable to your assembly standards. Ensure the mating card edge thickness falls within the 1.37 mm to 1.78 mm specification window.

Edgeboard Connectors Selection Notes

Select this component when high pin count density is required alongside robust mechanical retention via threaded inserts. The dual-row layout maximizes signal or power paths within a limited footprint. Verify compatibility with existing polarizing keying strategies to prevent misalignment during insertion. Consider the straight mounting style for direct panel-to-board interface scenarios.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles. The 305-086 variant specifically addresses applications requiring extensive I/O connectivity. It shares common design principles with other 305 series parts but differs in pin count and specific flange features.

Edgeboard Connectors Replacement Considerations

Direct substitutes include EDAC 305-086-521-508 and 305-086-500-201. Verify that alternative part numbers match the exact 86-position count, 3.96 mm pitch, and dual-row configuration. Ensure flange mounting hardware compatibility before substitution.
