305-042-521-204

Edgeboard Connectors Overview

The EDAC Inc. 305-042-521-204 is a standard card edge connector from the 305 series, designed for panel mounting with a vertical orientation. It features 42 positions arranged in a dual row configuration with a 0.156-inch (3.96 mm) pitch. The contacts are made of copper alloy with gold plating and utilize a solder lug termination type. The housing is constructed from green thermoplastic polyester, supporting board thicknesses between 0.054 and 0.070 inches.

Edgeboard Connectors Feature Summary

• Dual female contact configuration for non-specified card edge applications
• Solder lug termination ensures secure panel mounting connections
• Gold-plated copper alloy contacts provide reliable signal transmission
• Thermoplastic polyester insulation offers durability in industrial environments

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interfaces
• Communication equipment utilizing standard card edge modules
• Automotive electronics needing high-reliability interconnects
• Test and measurement devices with modular circuit board designs

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's official ordering guide to ensure correct flange and termination specifications. Confirm RoHS compliance status and environmental ratings prior to integration. Cross-reference the part number with current distributor availability as supply chains may vary. Ensure compatibility with existing PCB stack-up requirements regarding board thickness limits.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 42-position interface is required for vertical panel installation. The 3.96 mm pitch accommodates standard heavy-duty card edge layouts. Verify that the application environment falls within the specified operating temperature range. Consider the solder lug termination method for mechanical stability in high-vibration scenarios compared to surface mount alternatives.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 Series, which specializes in standard card edge solutions for demanding applications. The series provides various position counts and termination options to support diverse electronic assembly needs. The 305-042 variant specifically addresses higher-density connection requirements while maintaining the structural integrity associated with the brand's industrial-grade product line.

Edgeboard Connectors Replacement Considerations

Consult the official EDAC 305 Series Ordering Guide for direct substitutes with identical electrical and mechanical parameters. Alternative part numbers within the same series may offer different flange styles or termination types but must match the 42-position and 3.96 mm pitch constraints.
