305-086-500-578

Edgeboard Connectors Overview

The EDAC Inc. 305-086-500-578 is a standard card edge connector receptacle featuring 86 positions in a dual-row configuration. It utilizes a 0.156-inch (3.96 mm) contact spacing with a 0.140-inch row spacing, designed to accept printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). The contacts are gold-plated copper alloy, rated for 5 A current, and terminate via solder pins. Constructed with a green thermoplastic insulator body, this panel-mount component operates within a temperature range of -40°C to +105°C and offers an insulation resistance of 5 GOhms.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact plating thickness, housing color, and termination style variations. Ensure compatibility with the target PCB thickness of 0.062 inches. Cross-reference the 86-position count and dual-row layout with system mechanical constraints. Confirm RoHS compliance status through the latest documentation before procurement.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count interface is required for thick PCB applications. The 3.96 mm pitch suits designs prioritizing robustness over miniaturization. Verify that the panel-mount form factor aligns with the enclosure design. Consider the 5 A rating for power distribution needs alongside signal lines. Ensure the operating temperature range meets environmental requirements.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series provides various position counts and mounting styles for diverse electronic assembly needs. The 305-086-500-578 specifically addresses applications needing substantial I/O density in a dual-row format. It complements other series members by offering standardized dimensions for broad industry compatibility.

Edgeboard Connectors Replacement Considerations

Direct substitutes include EDAC part numbers sharing the same 86-position count, 3.96 mm pitch, and dual-row configuration, such as 305-086-500-201 or 305-086-500-202, pending verification of identical termination and mounting specifications.
