305-084-500-258

Edgeboard Connectors Overview

The EDAC Inc. 305-084-500-258 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features a dual female configuration with 84 positions arranged in two rows. The connector utilizes a 3.96 mm (0.156 inch) contact spacing and a 3.56 mm row spacing. It accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Termination is achieved via solder eyelets using copper alloy contacts plated with gold. The unit has a continuous current rating of 5 A and an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Dual-row female card edge interface with 84 positions
• Accepts 0.062 inch nominal thickness PCBs
• Solder eyelet termination for secure board connection
• Gold-plated copper alloy contacts for reliable conductivity

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring high-density connections
• Industrial control systems utilizing standard 0.062 inch thick circuit boards
• Communication equipment interfaces needing robust signal transmission
• Test and measurement instrumentation backplanes

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 84-position dual-row configuration before ordering. Confirm compatibility with 0.062 inch thick PCBs to ensure proper mechanical fit. Check regional availability as distribution status may vary by location. Ensure soldering processes are compatible with the specified eyelet termination style. Review environmental ratings if operation exceeds standard temperature ranges.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count vertical connector is required for panel mounting. The 3.96 mm pitch suits applications where space efficiency is balanced with ease of assembly. Consider the 5 A current rating for power or signal lines within these limits. Verify that the target PCB design accommodates the dual-row layout and solder eyelet footprint requirements for reliable electrical performance.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which provides standard card edge solutions for various industrial and commercial applications. The series offers multiple position counts and termination options to accommodate different design needs. The 305-084-500-258 specifically addresses requirements for higher density connections while maintaining the structural integrity provided by the low-profile insulator body and robust metal contacts.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pin counts and pitch but different termination styles or housing materials. Cross-reference part numbers such as 305-084-500-278 for similar specifications with potential variations in packaging or minor physical attributes. Always verify dimensional drawings and electrical ratings before substituting to ensure functional equivalence.
