306-023-420-103

Overview

The EDAC Inc. 306-023-420-103 is a dual-row female card edge connector designed for panel mount and through-hole termination. It features 46 positions with a 0.156-inch (3.96mm) pitch, utilizing tin-plated copper alloy contacts. The insulator body is constructed from high-temperature thermoplastic polyester, rated for operation between -40°C and +105°C. This component accepts printed circuit boards with thicknesses ranging from 0.054 to 0.070 inches (1.37mm to 1.78mm).

Feature Summary

• Dual-row female configuration with 46 total positions for robust signal connectivity.
• High-temperature thermoplastic polyester insulator ensures stability in demanding thermal environments.
• Panel mount installation with through-hole soldering for secure mechanical attachment.
• Tin-plated copper alloy contacts provide reliable electrical performance.

Applications

• Industrial control systems requiring durable interconnects.
• Telecommunications equipment infrastructure.
• Test and measurement instrumentation hardware.
• Automotive electronic modules.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 306 Series Ordering Guide to ensure compatibility with required board thickness and mounting variations. Confirm that the tin plating specification meets the application's corrosion resistance requirements. Cross-reference the RoHS compliance status with current regulatory standards before finalizing procurement orders.

Selection Notes

Select this connector when a dual-row interface with a 0.156-inch pitch is required for PCB-to-panel connections. Ensure the target printed circuit board thickness falls within the specified 0.054 to 0.070-inch range for proper contact engagement. Consider the operating temperature range of -40°C to +105°C for environmental suitability.
