306-022-420-178

Overview

The EDAC Inc. 306-022-420-178 is a dual-edge female card edge connector from the 306 series, designed for through-hole panel mounting. It features 44 positions with a 0.156-inch (3.96mm) contact spacing and accepts printed circuit boards with a thickness of 0.062 inches (1.57mm). The contacts are made of copper alloy with gold plating on the mating side to ensure reliable signal transmission. The insulator body is constructed from thermoplastic material, providing durability in demanding environments. This component supports vertical installation and operates within a temperature range of -40°C to +105°C, making it suitable for robust industrial applications requiring secure board-to-board or backplane connections.

Feature Summary

• Dual-edge female configuration for secure connection to double-sided PCBs
• Gold-plated copper alloy contacts ensure high conductivity and corrosion resistance
• Low-profile insulator body facilitates compact system integration
• Through-hole panel mount design provides mechanical stability

Applications

• Motherboard to daughterboard interconnections
• Signal communication in industrial control systems
• Power connection modules in electronic equipment
• Extender card interfaces in computing hardware

Procurement Notes

Verify that the specific ordering suffix matches the required contact plating and termination style. Confirm that the PCB thickness aligns with the connector's acceptance specifications. Ensure the mounting hole dimensions correspond to the panel installation requirements. Check for RoHS compliance status if environmental regulations apply to the final assembly. Validate the operating temperature range against the intended application environment.

Selection Notes

Choose this model when a dual-edge interface is required for double-sided circuit boards. Select based on the 0.156-inch pitch requirement for trace routing compatibility. Consider the gold plating option for applications prioritizing long-term reliability over cost. Evaluate the panel mount style against available space constraints. Compare thermal ratings to ensure suitability for the expected operational heat levels.

Part Context

This component belongs to the EDAC 306 series of standard card edge connectors. The series is engineered for quality power and signal connections between motherboards, daughterboards, and extenders. The 306 series typically offers various position counts and mounting options to accommodate diverse design needs. This specific part represents a mid-range position count variant within the broader product family.

Replacement Considerations

Consult the official EDAC 306 Series Ordering Guide for verified substitute part numbers. Cross-reference pin counts, pitch, and mounting styles before substitution. Verify that any alternative maintains the same electrical and mechanical specifications.
