305-054-500-208

Edgeboard Connectors Overview

The EDAC Inc. 305-054-500-208 is a dual-edge female card edge connector from the 305 series, featuring 54 positions with a 0.156-inch (3.96 mm) contact spacing. It utilizes wire hole termination for soldering and includes gold-plated contacts to ensure reliable signal transmission. The unit is constructed with a green thermoplastic insulator and copper alloy terminals, designed for panel mount installation. It supports board thicknesses within specified mechanical limits and operates reliably across a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration for secure board insertion
• Gold-plated contacts for enhanced conductivity and corrosion resistance
• Wire hole termination style for robust solder joint formation
• Thermoplastic insulator housing providing structural stability

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules
• Embedded computing hardware interfaces

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 54-position count and 0.156-inch pitch before procurement. Confirm compliance with RoHS3 standards if environmental regulations apply to the assembly. Ensure the receiving facility has appropriate handling procedures for sensitive electronic components. Cross-reference the manufacturer's ordering guide to validate any suffix variations against the intended mechanical specifications.

Edgeboard Connectors Selection Notes

Select this component when a high-density connection with 54 positions is required on a dual-edge interface. The 0.156-inch spacing accommodates standard board layouts while maintaining signal integrity. Consider the wire hole termination method if through-hole soldering processes are preferred over surface mount alternatives. Evaluate the operating temperature range to ensure compatibility with the expected thermal environment of the final application.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 Series, which defines a family of card edge connectors characterized by a consistent 0.156-inch contact spacing. The series offers various position counts and termination styles to suit different density requirements. The 305-054-500-208 variant specifically addresses applications needing a moderate-to-high pin count with durable gold plating and standard panel mounting capabilities.

Edgeboard Connectors Replacement Considerations

Direct substitutes must maintain the 54-position count, 0.156-inch pitch, and dual-edge female configuration. Verify that alternative parts support the same wire hole termination style and compatible board thickness ranges. Ensure the replacement meets the same electrical ratings and material composition standards for insulation and contact plating.
