306-021-420-158

Overview

The EDAC Inc. 306-021-420-158 is a dual female card edge connector from the 306 series, designed for panel and through-hole mounting. It features 42 positions with a 0.156-inch (3.96mm) contact spacing and accepts printed circuit boards with thicknesses ranging from 0.054 to 0.070 inches. The connector utilizes gold-plated copper alloy contacts with a 10.0µin thickness and employs cantilever contact types. Insulation is provided by thermoplastic polyester, ensuring reliable performance across an operating temperature range of -40°C to 105°C.

Feature Summary

• Dual female configuration with cantilever contacts for secure board insertion
• Gold-plated terminals ensure durable electrical connectivity
• Thermoplastic polyester insulation provides stable dielectric properties
• Panel mount design with flange features for rigid installation

Applications

• Industrial control system interconnections
• Telecommunications equipment backplanes
• Medical device internal circuitry
• Consumer electronics module interfaces

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact pin count, plating thickness, and flange specifications. Ensure compatibility with target PCB thickness limits and mounting hole patterns before procurement. Cross-reference the component status to confirm current availability and lead times directly with authorized distributors or the manufacturer.

Selection Notes

Select this component when a high-density dual-sided connection is required with robust mechanical retention. The 0.156-inch pitch suits applications where standard spacing is preferred over finer pitches. Evaluate thermal requirements against the -40°C to 105°C rating and ensure the panel mounting style aligns with the enclosure design constraints.

Part Context

This part belongs to the EDAC 306 series, which focuses on standard card edge connectors. The series offers various position counts and mounting options, catering to general-purpose industrial and commercial applications. The 306 series is characterized by its reliability in harsh environments and standardized dimensions for easy integration into existing designs.

Replacement Considerations

Consult the EDAC 306 Series Ordering Guide for direct substitutes with differing pin counts or flange configurations. Verify that any alternative maintains the same 0.156-inch pitch and dual female contact type to ensure mechanical and electrical compatibility.
