305-086-555-258

Edgeboard Connectors Overview

The EDAC Inc. 305-086-555-258 is a standard card edge connector receptacle featuring 86 positions in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing with a 3.56 mm row spacing. Designed for .062 inch nominal thickness printed circuit boards, the unit employs gold-plated copper alloy contacts and a green thermoplastic insulator body. The connector supports a 5 A current rating and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body designed for straddle mount installation
• Provides high insulation resistance rated at 5 GOhms

Edgeboard Connectors Applications

• Card extender systems requiring dual-edge connectivity
• Straddle mount applications for vertical panel integration
• High-density electronic assemblies utilizing .062 inch PCB standards

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to confirm exact termination style and housing color variations. Ensure compatibility with the target PCB thickness of .062 inches before procurement. Cross-reference the 86-position count with system slot requirements to prevent mechanical interference during assembly.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 86-position interface is required for .062 inch thick boards. The 3.96 mm pitch suits applications needing robust electrical connections with 5 A capacity. Consider the straddle mount style for panel mounting needs where space efficiency and low profile are critical design constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options while maintaining consistent 3.96 mm spacing. The 305-086-555-258 specifically addresses high-pin-count requirements with a dual female configuration suitable for complex signal routing.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with matching 86 positions and 3.96 mm pitch, such as the 305-086-500-201 or 305-086-555-558, provided the termination and mounting style align with the design.
