305-086-556-258

Edgeboard Connectors Overview

The EDAC Inc. model 305-086-556-258 is a standard card edge connector receptacle featuring 86 positions with a 3.96 mm (0.156 inch) contact spacing and 3.56 mm row spacing. It accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The component utilizes gold-plated copper alloy contacts for reliable signal transmission and employs a solder termination type for secure PCB mounting. Designed for dual-edge card engagement, this green thermoplastic housing ensures durability in standard interconnect applications.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design accommodating 0.062 inch thick PCBs
• Gold-plated copper alloy contacts ensure corrosion resistance and conductivity
• Thermoplastic housing provides structural integrity and insulation

Edgeboard Connectors Applications

• General purpose electronic board-to-board interconnections
• Industrial control system module interfaces
• Telecommunications equipment backplane connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm exact pin configuration and termination style. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Cross-reference the RoHS compliance status with the latest regulatory documentation provided by EDAC Inc. to meet environmental standards for your specific project requirements.

Edgeboard Connectors Selection Notes

Select this component when a high-density 86-position interface is required for dual-edge cards. The 3.96 mm pitch offers a balance between signal density and manufacturing ease. Consider the vertical panel mount style if space constraints dictate a perpendicular connection relative to the mating board. Verify that the 5 A current rating per contact aligns with the electrical load requirements of the application.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, designed for robust performance in demanding environments. The series offers various position counts and housing colors to suit different identification needs. As a receptacle, it mates with corresponding header components or direct card edges, providing a stable mechanical and electrical link within larger assembly systems.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series variants with matching 86 positions and 3.96 mm pitch, such as 305-086-500-201, provided the housing color and specific termination details are verified against the original design specifications.
