306-036-400-178

Overview

The EDAC Inc. 306-036-400-178 is a dual-edge female card edge connector featuring 72 positions arranged in two rows of 36 contacts each. It utilizes a 0.156-inch (3.96mm) contact pitch and is designed for panel mounting via solder lug termination. The connector accepts non-specified dual-edge cards with thicknesses ranging from 0.054 to 0.070 inches. Contacts are made of copper alloy with tin plating, housed in green thermoplastic polyester insulation, and operate within a temperature range of -40°C to +105°C.

Feature Summary

• Dual-edge female configuration for secure mating with double-sided circuit boards
• Panel mount design with solder lug termination for robust mechanical stability
• Tin-plated copper alloy contacts ensure reliable signal transmission
• Green thermoplastic polyester housing provides thermal resistance up to 105°C

Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Medical device internal board connections
• Consumer electronics modular assemblies

Procurement Notes

Verify the specific ordering suffix against the official EDAC 306 Series Ordering Guide to confirm contact plating and flange characteristics. Ensure the target PCB or card edge thickness falls within the specified 0.054 to 0.070 inch range for proper engagement. Confirm that the application environment remains within the -40°C to +105°C operational limits defined by the manufacturer's specifications.

Selection Notes

Select this component when a high-density dual-edge interface is required for panel-mounted applications. The 72-position count supports substantial I/O requirements compared to lower-count variants. Verify compatibility with existing tooling for the 0.156-inch pitch. Consider the tin plating option if cost efficiency is prioritized over the corrosion resistance offered by gold-plated alternatives in similar series models.

Part Context

This part belongs to the EDAC 306 Series, a line of standard card edge connectors known for their versatility in various electronic assemblies. The series offers multiple position counts and termination options to accommodate different design constraints. The 306-036-400-178 specifically addresses needs for dual-edge connectivity with a focus on durable panel integration using standard industrial spacing metrics.

Replacement Considerations

Direct substitutes within the same series include parts with identical pin counts and pitch but different plating, such as the 306-036-500-178 which features gold plating instead of tin. Cross-series replacements like the 316 or 356 series may offer similar form factors but require verification of flange dimensions and row configurations to ensure mechanical fit.
