305-042-520-204

Edgeboard Connectors Overview

The EDAC Inc. 305-042-520-204 is a standard card edge connector from the 305 series, designed for vertical panel mounting. It features a dual female configuration with 42 positions arranged in two rows of 21 contacts each. The connector utilizes a 0.156-inch (3.96 mm) pitch and accepts board thicknesses ranging from 0.054 to 0.070 inches (1.37 mm to 1.78 mm). Contacts are constructed from copper alloy with gold plating and terminate via solder lug connections.

Edgeboard Connectors Feature Summary

• Dual-sided female contact configuration for reliable signal transmission
• Vertical panel mount design with flange for secure installation
• Gold-plated copper alloy contacts ensuring corrosion resistance
• Solder lug termination method for robust PCB attachment

Edgeboard Connectors Applications

• Industrial control systems requiring high-density interconnects
• Telecommunications equipment backplanes
• Automotive electronics modules

Edgeboard Connectors Procurement Notes

Verify the complete part number including suffixes to ensure correct contact type and plating specifications. Confirm RoHS compliance status as required by project regulations. Check manufacturer lead times as availability may vary. Ensure compatibility with specified board thickness ranges before ordering. Validate that the selected variant matches the required current rating and temperature operating range.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with 42 positions is required. The 3.96 mm pitch accommodates specific board layout constraints. Verify that the vertical mounting style fits the enclosure design. Ensure the solder lug termination method aligns with the assembly process capabilities. Confirm that the green thermoplastic polyester housing meets environmental requirements.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 Series, which offers various configurations for card edge applications. The series provides options for different row counts, positions, and mounting styles. The 305-042-520-204 specifically addresses needs for dual-sided connectivity with a standardized pitch. It complements other EDAC connectors within the same family for system expansion.

Edgeboard Connectors Replacement Considerations

Direct substitutes include EDAC part numbers sharing the same 305 series base code and position count, such as 305-042-520-202 or 305-042-520-208, provided electrical and mechanical parameters match exactly. Cross-brand replacements require rigorous validation of pinout, pitch, and housing dimensions.
