305-074-500-201

Edgeboard Connectors Overview

The EDAC Inc. 305-074-500-201 is a standard card edge connector receptacle featuring 74 positions arranged in a dual-row configuration. It utilizes a 0.156-inch (3.96 mm) contact spacing and accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). The component employs gold-plated copper alloy contacts for reliable signal transmission and offers a continuous current rating of 5 A. Designed for panel mounting, it features a vertical orientation and includes provisions for between-contact and in-contact polarizing keys to ensure correct board insertion.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for precise board alignment
• Features a low-profile insulator body constructed from thermoplastic material
• Provides a 5 A continuous current rating with 1800 VACrms insulation capability

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring secure card edge connections
• Industrial control systems utilizing standardized PCB modules
• Communication equipment interfaces demanding high insulation resistance

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm the exact contact plating thickness and housing color variant. Ensure that the selected polarizing key accessories are compatible with the .156 inch spacing and row configuration. Confirm that the receiving PCB meets the nominal 0.062 inch thickness specification for proper mechanical engagement. Check RoHS compliance status against current regulatory requirements for the target market.

Edgeboard Connectors Selection Notes

Select this model when a dual-edge female connector with 74 positions is required for vertical panel installation. Consider the 5 A current rating and 1800 VACrms insulation strength for electrical safety margins. Evaluate the need for polarizing keys if strict insertion orientation is critical. Compare against other series members if different board thicknesses or contact counts are necessary.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series provides various position counts and mounting styles for diverse electronic interconnect needs. The 305-074-500-201 specifically addresses applications requiring a high-density dual-row interface with robust mechanical retention and electrical performance standards.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include part numbers such as 305-074-500-203 or 305-074-500-504, which may differ in housing material or termination style. Verify pin count, spacing, and mounting orientation before substitution.
