306-036-521-104

Overview

The EDAC Inc. 306-036-521-104 is a dual-edge female card edge connector with 72 positions and a 0.156-inch (3.96mm) contact spacing. It features gold-plated contacts on a copper alloy substrate, housed in a green thermoplastic polyester insulator. Designed for panel mounting via solder lug termination, it accepts PCBs with thicknesses ranging from 0.054 to 0.070 inches. The unit operates within a temperature range of -40°C to 105°C and includes flange features for flush installation.

Feature Summary

• Dual-edge female configuration providing 72 connection points across two rows
• Gold-plated contact surfaces ensure reliable signal transmission and corrosion resistance
• Panel mount design with solder lug termination for secure mechanical attachment
• Flush-mount flange characteristics facilitate standardized board integration

Applications

• Medical interconnect solutions including ventilators and CPAP machines
• Ambulance communication and monitoring systems
• Hospital room equipment connections
• General industrial control panels requiring robust edge board interfaces

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current 306 Series Ordering Guide to confirm exact plating thickness and material specifications. Ensure compatibility with the target printed circuit board thickness range of 0.054 to 0.070 inches before finalizing procurement orders. Cross-reference the RoHS3 compliance status with latest regulatory requirements for the intended market destination.

Selection Notes

Select this component when a high-density dual-edge interface with 72 positions is required for panel-mounted applications. The 0.156-inch pitch accommodates standard heavy-duty board layouts. Consider the operating temperature range of -40°C to 105°C for environmental suitability. Verify that the flush-mount flange dimensions align with the chassis cutout specifications to ensure proper physical fit during assembly.

Part Context

This part belongs to the EDAC 306 Series, a line of standard card edge connectors designed for durable interconnect applications. The series offers various position counts and termination styles, catering to diverse industrial and medical needs. The 306-036-521-104 specifically addresses requirements for dual-edge connectivity with robust mechanical retention through its panel mount design.

Replacement Considerations

Consult the official EDAC 306/316/356 Series Ordering Guide for direct substitutes. Verify that alternative parts match the 72-position count, 0.156-inch pitch, and dual-edge female configuration. Ensure thermal and mechanical specifications remain compatible with the existing system design constraints.
