306-007-421-158

Edgeboard Connectors Overview

The EDAC Inc. 306-007-421-158 is a dual-edge female card edge connector designed for panel and through-hole mounting. It features 14 positions with a 0.156-inch (3.96mm) contact spacing across two rows. The connector utilizes tin-plated cantilever contacts to accept non-specified dual-edge PCBs with thicknesses ranging from 0.054 to 0.070 inches. Constructed with a green thermoplastic polyester insulator, it supports solder termination and operates within a temperature range of -40°C to 105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration with cantilever contact type for reliable board insertion
• Panel mount design with flange featuring top opening and threaded inserts
• Tin-plated contact surface finish ensuring corrosion resistance
• Thermoplastic polyester insulator body rated for industrial operating temperatures

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Medical device internal circuit board connections
• Consumer electronics module interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact plating, as the 306 series distinguishes between tin and gold finishes via part number codes. Ensure the target PCB thickness falls within the specified 0.054 to 0.070 inch range for proper mechanical engagement. Confirm that the application environment remains within the -40°C to 105°C operational limits defined by the material specifications.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with 0.156-inch spacing is required for panel-mounted applications. The tin-plated contacts are suitable for general-purpose environments where high-cycle durability is not the primary constraint compared to gold-plated variants. Ensure the mounting hole pattern aligns with the flange's threaded insert specifications for secure installation.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 306 Series, which provides standard card edge solutions with 0.156-inch spacing. The series offers various position counts and mounting styles, catering to diverse electronic assembly needs. The 306-007-421-158 specifically addresses requirements for low-profile, dual-sided board connections in compact panel-mounted configurations.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 306 series connectors with matching pin counts and spacing, such as 306-007-521-158, though contact plating differences must be evaluated. Cross-brand replacements require verification of identical mechanical dimensions, electrical ratings, and mounting interface compatibility.
