306-032-400-178

Overview

The EDAC Inc. 306-032-400-178 is a dual-edge female card edge connector featuring 64 positions arranged in two rows of 32 contacts each. It utilizes a 0.156-inch (3.96mm) contact spacing and accepts printed circuit boards with thicknesses ranging from 0.054 to 0.070 inches. The component employs tin-plated cantilever contacts for termination via solder eyelets, housed within a green thermoplastic polyester insulator. Designed for panel mounting with flush features, it operates reliably within a temperature range of -40°C to 105°C.

Feature Summary

• Dual-edge receptacle design accommodating non-specified double-sided PCBs
• Cantilever contact type ensuring secure board retention
• Flush panel mount configuration with top opening
• Thermoplastic polyester insulation for thermal stability

Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current 306 Series Ordering Guide to ensure compatibility with required termination styles and plating specifications. Confirm that the selected variant matches the intended PCB thickness and mounting constraints. Cross-reference the part number with official distributor catalogs to validate current availability status and lead times prior to finalizing procurement orders.

Selection Notes

Select this connector when high-density interconnection is required with a 0.156-inch pitch. Ensure the application environment remains within the specified -40°C to 105°C operating range. Verify that the target PCB thickness falls within the 0.054 to 0.070 inch acceptance window. Confirm that the tin-plated contact finish meets the corrosion resistance requirements for the intended service life.

Part Context

This component belongs to the EDAC 306 Series, a line of standard card edge connectors designed for robust industrial applications. The series offers various position counts and termination options, providing flexibility for diverse board-to-board and board-to-backplane connections. The 306-032-400-178 specifically addresses needs for dual-edge connectivity with substantial pin counts.

Replacement Considerations

Consult the EDAC 306 Series cross-reference documentation for direct substitutes. Consider variants such as 306-032-520-178 if additional row terminations or alternative mounting solutions are required. Ensure any replacement maintains identical electrical ratings and mechanical dimensions.
