306-036-520-178

Overview

The EDAC Inc. 306-036-520-178 is a standard card edge connector receptacle featuring 72 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) contact pitch and is designed for PCBs with a thickness of 1.57 mm. The connector employs gold-plated copper alloy contacts to ensure reliable signal transmission, with a current rating of 5 A. Constructed with a green thermoplastic polyester housing, it supports panel mount installation and offers vertical orientation for secure mating with card edge modules.

Feature Summary

• Dual-edge female contact design for robust board-to-board connectivity
• Gold-plated copper alloy terminals for enhanced conductivity and corrosion resistance
• Thermoplastic polyester insulator providing structural stability and environmental protection

Applications

• Industrial control system interconnections
• Telecommunications equipment backplanes
• Medical device internal circuitry
• Energy management hardware interfaces

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact pin count, termination style, and plating specifications. Ensure compatibility with the target PCB thickness and mounting requirements before procurement. Cross-reference the component number with authorized distributors to confirm availability and authenticity, as supply chain variations may exist for this series.

Selection Notes

Select this component when a high-density dual-row interface is required for rigid board connections. The 3.96 mm pitch accommodates standard card edge profiles while the 5 A rating suits moderate power applications. Consider the panel mount style for fixed installations where vibration resistance and precise alignment are critical for long-term reliability in demanding environments.

Part Context

This part belongs to the EDAC 306 series of standard card edge connectors, a line established for general-purpose electronic interconnects. The series provides various position counts and mounting options to support diverse industrial and commercial applications. As a receptacle type, it complements corresponding card edge plugs to form complete connection assemblies within larger electronic systems.

Replacement Considerations

Direct substitutes must match the 72-position dual-row layout, 3.96 mm pitch, and panel mount configuration. Verify that alternative components maintain identical gold plating specifications and thermal ratings. Consult the manufacturer's cross-reference guide for officially confirmed equivalent part numbers to ensure mechanical and electrical interchangeability.
