306-023-521-107

Overview

The EDAC Inc. 306-023-521-107 is a standard card edge connector from the 306 series, designed for dual-edge board applications. It features 46 positions with a 0.156-inch (3.96mm) contact spacing and accepts PCBs with a nominal thickness of 0.062 inches (1.57mm). The connector utilizes copper alloy contacts with gold plating and a green thermoplastic insulator body. Rated for 5A current and offering 5 GOhms insulation resistance, it supports panel mounting in a vertical orientation within an operating temperature range of -40°C to +105°C.

Feature Summary

• Dual-edge female connector design accommodating non-specified double-sided circuit boards
• Low-profile insulator body constructed from green thermoplastic material
• Gold-plated copper alloy contacts ensuring reliable signal transmission
• Panel mount installation style with vertical orientation

Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement devices needing high-reliability signal paths
• General-purpose electronic assemblies with specified PCB thickness constraints

Procurement Notes

Verify the specific manufacturer part number against official EDAC documentation to confirm compatibility with dual-edge PCBs. Ensure that the required PCB thickness aligns with the 0.062-inch specification. Confirm that the operating environment remains within the stated temperature limits. Check for RoHS compliance requirements if applicable to your assembly standards. Validate that the panel mounting configuration matches your mechanical design constraints before finalizing procurement.

Selection Notes

Select this component when a dual-edge connector is required for vertical panel mounting applications. The 0.156-inch pitch suits designs needing wider spacing between connections. Consider the 5A current rating for power or signal distribution needs. The gold plating offers corrosion resistance suitable for various environmental conditions. Ensure the target PCB thickness falls within the acceptable range for proper contact engagement.

Part Context

This component belongs to the EDAC 306 series, which specializes in standard card edge connectors. The series is characterized by low-profile bodies and versatile mounting options. The 306-023-521-107 variant specifically addresses dual-edge board integration needs. It represents a standardized solution for industrial and commercial electronics requiring reliable board-to-board or board-to-panel connections.

Replacement Considerations

Consult the EDAC 306, 316, and 356 Series Ordering Guide for verified substitute part numbers. Cross-reference specifications such as position count, pitch, and mounting style to ensure functional equivalence. Verify that any alternative maintains the same current rating and insulation resistance values.
