306-028-520-104

Overview

The EDAC Inc. 306-028-520-104 is a dual-edge female card edge connector with 56 positions arranged in two rows of 28 contacts each. It features a 0.156-inch (3.96mm) pitch and utilizes gold-plated copper alloy contacts with a thickness of 10.0µin (0.25µm). Designed for panel mounting via solder lug termination, it accommodates board thicknesses between 0.054" and 0.070" (1.37mm to 1.78mm). The housing is constructed from green thermoplastic polyester, ensuring compliance with RoHS3 standards.

Feature Summary

• Dual-edge female contact configuration for non-specified card types
• Gold-plated copper alloy contacts for reliable signal transmission
• Thermoplastic polyester insulation material for durability
• Panel mount installation with solder lug termination

Applications

• Medical interconnect solutions such as ventilators
• Ambulance communication and monitoring systems
• CPAP machine connectivity
• General medical room equipment interfaces

Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and housing color variations. Ensure that the selected variant matches the required board thickness range of 0.054" to 0.070". Confirm RoHS3 compliance status through the manufacturer's latest environmental declarations before finalizing procurement orders.

Selection Notes

Select this component when a high-density 56-position interface is required for dual-edge cards. The 0.156" pitch suits applications needing robust mechanical stability. Verify that the operating temperature range of -40°C to 105°C aligns with the environmental conditions of the target system. Ensure panel cutout dimensions accommodate the flange characteristics for proper alignment.

Part Context

This part belongs to the EDAC 306 Series, a line of standard card edge connectors designed for industrial and medical applications. The series offers various position counts and termination styles. The 306-028-520-104 specifically addresses needs for dual-sided connectivity with a focus on corrosion resistance provided by the gold finish and structural integrity from the thermoplastic housing.

Replacement Considerations

Direct substitutes within the same series include parts like 306-028-520-101 or 306-028-506-102, which share the 56-position count and 0.156" pitch. Verify that any alternative part number maintains identical termination style and board thickness compatibility before substitution.
