305-080-556-503

Edgeboard Connectors Overview

The EDAC Inc. 305-080-556-503 is a dual-edge female card edge connector from the 305 Series, designed for board-to-board interconnection. It features 80 positions with a 0.156-inch (3.96 mm) pitch across two rows. The contacts are made of copper alloy with a gold plating finish to ensure reliable signal transmission. The housing is green thermoplastic polyester, rated for operation between -40°C and +105°C. It supports card thicknesses of 0.054 to 0.070 inches and utilizes a solder termination method for secure PCB mounting.

Edgeboard Connectors Feature Summary

• Dual-row female configuration for high-density signal routing
• Gold-plated copper alloy contacts for corrosion resistance
• Thermoplastic polyester insulation for thermal stability

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interfaces
• Computing hardware expansion slots

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current 305 Series Ordering Guide to confirm contact plating thickness and flange characteristics. Ensure the target application accommodates the specified 0.156-inch pitch and dual-edge mating requirements. Confirm RoHS compliance status matches project environmental standards before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female interface is required for non-specified cards with a 3.96 mm pitch. Consider the 80-position count for circuit density needs. Evaluate the -40°C to +105°C operating range against environmental conditions. Verify that the solder termination style aligns with the assembly process capabilities of the manufacturing facility.

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 options, including panel mount and through-hole configurations. The 305-080 variant specifically provides a mid-range capacity within the product line, balancing connectivity density with physical footprint constraints for standard industrial applications.

Edgeboard Connectors Replacement Considerations

Consult the official EDAC 305 Series cross-reference documentation for direct substitutes. Verify compatibility regarding pitch, row count, and termination type before substituting.
