306-023-421-158

Overview

The EDAC Inc. 306-023-421-158 is a dual-sided female card edge connector designed for panel mount and through-hole termination. It features 46 positions with a 0.156-inch (3.96 mm) pitch, arranged in two rows of 23 contacts per side. The connector utilizes tin-plated copper alloy cantilever contacts and a green thermoplastic polyester insulator. It supports board thicknesses ranging from 0.054 to 0.070 inches (1.37 to 1.78 mm). The unit operates within a temperature range of -40°C to 105°C and complies with RoHS3 standards.

Feature Summary

• Dual-sided female contact configuration for secure board insertion
• Cantilever spring contact design ensures reliable electrical connection
• Thermoplastic polyester insulation provides thermal stability
• Panel mount flange with top opening facilitates installation

Applications

• Industrial control system interconnects
• Medical device circuit board connections
• Agricultural technology equipment interfaces
• General-purpose electronic module mounting

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 306 Series Ordering Guide to ensure correct plating and contact type specifications. Confirm that the target PCB thickness falls within the supported range of 0.054 to 0.070 inches. Check current availability status as distribution channels may indicate limited stock or order-based fulfillment. Ensure compliance with required environmental certifications such as RoHS3 before final procurement approval.

Selection Notes

Select this component when a dual-sided female connector with a 0.156-inch pitch is required for vertical panel mounting. The cantilever contact style is suitable for repeated insertion cycles without soldering the board directly. Consider the green color coding for visual identification if applicable. Verify that the through-hole termination method aligns with the assembly process. Ensure the operating temperature range meets the environmental demands of the intended application.
