306-035-500-158

Overview

The EDAC Inc. 306-035-500-158 is a dual-edge female card edge connector from the 306 series, featuring 70 positions with a 0.156-inch (3.96mm) contact spacing. It utilizes copper alloy cantilever contacts with gold plating for reliable signal transmission. The connector supports PCB thicknesses between 0.054 and 0.070 inches and operates within a temperature range of -40°C to 105°C. Designed for panel mounting via solder eyelets, it employs thermoplastic polyester insulation and features a green housing with flush-mount flanges.

Feature Summary

• Dual-edge female configuration with cantilever spring contacts for secure board retention
• Gold-plated copper alloy contacts ensure low resistance and corrosion resistance
• Thermoplastic polyester insulation provides thermal stability and mechanical strength
• Panel mount design with flush-mount flanges and solder eyelet termination

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 306 Series Ordering Guide to confirm contact type, plating thickness, and housing color. Ensure compatibility with the target PCB edge thickness range of 0.054 to 0.070 inches. Confirm that the required contact spacing of 0.156 inches matches the system design specifications before procurement.

Selection Notes

Select this component when a high-density dual-edge interface is required with robust mechanical retention. The 0.156-inch pitch accommodates larger traces compared to standard 0.100-inch connectors. Consider the operating temperature range and gold plating requirements for harsh environments. Verify that the panel mount style fits the enclosure constraints and that the solder eyelet termination method aligns with the assembly process.

Part Context

This part belongs to the EDAC 306 series of card edge connectors, characterized by a 0.156-inch contact spacing. The series offers various position counts and termination styles, designed for durable industrial applications. The 306 series typically features cantilever contacts and thermoplastic insulation, providing a balance of electrical performance and mechanical reliability for double-sided circuit boards.

Replacement Considerations

Cross-reference with other EDAC 306 series variants such as 306-035-500-104 or 306-035-500-158 if different housing colors or plating thicknesses are needed. Ensure any substitute maintains the 0.156-inch pitch and 70-position count. Verify that alternative parts support the same PCB thickness range and panel mount requirements.
