306-035-400-178

Overview

The EDAC Inc. 306-035-400-178 is a dual female card edge connector designed for panel mounting applications. It features 70 total positions arranged in two rows of 35 contacts each, with a standard spacing of 0.156 inches (3.96 mm). The connector utilizes copper alloy cantilever contacts with a gold plating finish to ensure reliable signal transmission. It is engineered to accommodate printed circuit boards with thicknesses ranging from 0.054 to 0.070 inches (1.37 mm to 1.78 mm). The housing is constructed from thermoplastic polyester and includes flange features for secure installation.

Feature Summary

• Dual female contact configuration provides robust connection points for double-sided card edges.
• Gold-plated cantilever spring contacts ensure low insertion force and high durability during repeated mating cycles.
• Panel mount design with integrated flanges allows for stable mechanical fixation on chassis or enclosures.

Applications

• Industrial control systems requiring durable board-to-board interconnects
• Telecommunications equipment utilizing standard card edge modules
• Test and measurement instrumentation interfaces

Procurement Notes

Verify the specific suffix codes against the manufacturer's ordering guide to confirm contact plating thickness and insulation material variations. Ensure that the selected variant matches the required thermal rating and environmental compliance standards for the target deployment zone. Cross-reference the package quantity with distributor specifications to align with assembly line requirements.

Selection Notes

Select this component when a high-density dual-row interface is required for standard thickness PCBs. Confirm that the 0.156-inch pitch aligns with the existing board layout constraints. Evaluate the operating temperature range of -40°C to 105°C against the environmental conditions of the final application to ensure long-term reliability under thermal stress.

Part Context

This part belongs to the EDAC 306 series of standard card edge connectors. The series is characterized by its use of thermoplastic polyester insulation and copper alloy contacts. It serves as a foundational interconnect solution within the broader EDAC portfolio, offering standardized dimensions and reliable performance for general-purpose electronic assemblies.

Replacement Considerations

Consult the official EDAC 306 Series Ordering Guide for direct substitutes. Variants such as 306-035-400-168 or 306-035-400-107 may offer alternative packaging or minor specification differences while maintaining compatible form factors.
