305-042-555-201

Edgeboard Connectors Overview

The EDAC Inc. 305-042-555-201 is a standard card edge connector from the 305 series, designed for panel mount applications. It features a dual female configuration with 42 positions arranged in two rows. The connector utilizes a 0.156-inch (3.96 mm) pitch and supports board thicknesses ranging from 0.054 to 0.070 inches (1.37 mm to 1.78 mm). Contacts are made of copper alloy with gold plating, ensuring reliable signal transmission. The housing is constructed from green thermoplastic polyester, providing durability and insulation.

Edgeboard Connectors Feature Summary

• Dual female contact configuration for secure card edge mating
• Gold-plated copper alloy contacts for corrosion resistance
• Thermoplastic polyester insulation for thermal stability
• Panel mount installation style with vertical orientation

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Communication equipment backplanes

Edgeboard Connectors Procurement Notes

Verify the complete part number including suffixes to ensure correct termination type and plating specifications. Confirm that the target application requires a dual female connector compatible with the specified board thickness range. Check RoHS compliance status if environmental regulations apply to the end product. Ensure sourcing channels provide original manufacturer documentation for quality assurance.

Edgeboard Connectors Selection Notes

Select this component when a high-density 42-position interface is required with a 3.96 mm pitch. Consider the operating temperature range of -40°C to +105°C for harsh environments. Evaluate the need for gold plating on contacts to minimize contact resistance over time. Compare against other series members if different mounting styles or row configurations are needed.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting options. The 305-042-555-201 specifically addresses needs for dual-row, panel-mounted interfaces. It complements other EDAC products by providing standardized dimensions and reliable performance for PCB-to-PCB or PCB-to-backplane connections.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include variations in position count or termination style. Verify compatibility with existing board layouts and housing dimensions before replacement. Cross-reference with EDAC's ordering guide for equivalent parts with modified suffixes.
