306-031-400-158

Overview

The EDAC Inc. 306-031-400-158 is a dual female card edge connector from the 306 series, featuring 62 positions with a 0.156-inch (3.96mm) spacing. It utilizes cantilever contacts made of copper alloy with tin plating for reliable signal transmission. Designed for panel and through-hole mounting, it accommodates board thicknesses between 0.054 and 0.070 inches. The housing is constructed from thermoplastic polyester, ensuring durability across an operating temperature range of -40°C to 105°C.

Feature Summary

• Dual-sided female contact configuration for secure board insertion
• Cantilever spring contact design for low insertion force and high cycle life
• Thermoplastic polyester insulation providing structural stability and thermal resistance
• Tin-plated copper alloy terminals ensuring corrosion resistance and conductivity

Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Consumer electronic circuit board assemblies
• Medical device internal connections

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 306 Series Ordering Guide to ensure compatibility with required pin counts and termination styles. Confirm that the tin plating specification meets the environmental requirements of the target application. Check RoHS compliance status as per current regulatory standards before finalizing procurement orders.

Selection Notes

Select this component when a robust, high-spacing connector is required for double-sided card edge applications. The 0.156-inch pitch allows for wider trace routing compared to finer pitches. Ensure the mating board thickness falls within the specified 0.054 to 0.070 inch range to guarantee proper contact engagement and mechanical retention during operation.

Part Context

This part belongs to the EDAC 306 series, which offers various configurations for card edge connectivity. The series is characterized by its durable construction and suitability for general-purpose industrial and commercial electronics. The 306-031 base number indicates the specific housing style and contact arrangement within the broader product family.

Replacement Considerations

Consult the official EDAC 306 Series cross-reference documentation for verified substitute part numbers. Direct replacements must match the 62-position count, 0.156-inch pitch, and dual female configuration. Verify that any alternative maintains the same thermal rating and mounting specifications.
