305-074-555-502

Edgeboard Connectors Overview

The EDAC Inc. 305-074-555-502 is a dual-edge female card edge connector designed for high-density interconnect applications. It features 74 positions with a 0.156-inch (3.96mm) pitch, arranged in two rows of 37 contacts each. The connector utilizes gold-plated copper alloy contacts and a green thermoplastic polyester insulator. It supports board thicknesses ranging from 0.054 to 0.070 inches and operates within a temperature range of -40°C to 105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration for secure mating with non-specified double-sided circuit boards
• Gold-plated contacts ensure reliable signal transmission and corrosion resistance
• Thermoplastic polyester insulation provides structural stability and thermal endurance

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connectivity
• Telecommunications infrastructure equipment
• Automotive electronic modules

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 305 Series Ordering Guide to confirm contact plating thickness and flange characteristics. Ensure compatibility with target PCB edge thickness specifications before procurement. Confirm RoHS compliance status through current distributor documentation.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 74-position interface is required for double-sided card edge applications. Consider the 0.156-inch pitch constraint and verify that the mating board thickness falls within the specified 0.054 to 0.070-inch range. Evaluate thermal requirements against the -40°C to 105°C operating limit.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers various mounting styles and position counts for standard card edge connectors. The series is characterized by its use of thermoplastic polyester materials and gold-plated copper alloy contacts, providing a standardized solution for high-reliability interconnect needs across multiple industries.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series cross-reference data for direct substitutes. Verify that any alternative maintains the 74-position count, 0.156-inch pitch, and dual-edge female configuration to ensure mechanical and electrical compatibility.
