306-018-421-108

Edgeboard Connectors Overview

The EDAC Inc. model 306-018-421-108 is a standard card edge connector from the 306 series, designed for panel mount installation with a vertical orientation. It features a dual female configuration with 36 total positions arranged in two rows, providing a 0.156-inch (3.96mm) pitch. The connector utilizes solder pin termination and copper alloy contacts with tin plating. It accommodates board thicknesses between 0.054 and 0.070 inches (1.37mm to 1.78mm). The insulator is made of green thermoplastic polyester, ensuring reliable performance within an operating temperature range of -40°C to 105°C.

Edgeboard Connectors Feature Summary

• Dual female contact configuration for secure edge board engagement
• Thermoplastic polyester insulator housing for environmental stability
• Vertical panel mount design with solder pin termination
• Copper alloy contacts with tin plating for conductivity

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Test and measurement instrument modules
• Automotive electronic sub-systems

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm terminal type and plating specifications. Ensure the target PCB thickness falls within the specified 1.37mm to 1.78mm range for proper mechanical fit. Confirm that the vertical panel mount style aligns with the enclosure design requirements before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-sided card edge interface with a 3.96mm pitch is required. The vertical mounting orientation suits applications where space constraints dictate a perpendicular connection relative to the mating board. Verify that the tin-plated contacts meet the corrosion resistance needs of the intended environment compared to gold-plated alternatives.

Edgeboard Connectors Part Context

This part belongs to the EDAC 306 series of standard card edge connectors, which offers extensive customization options for position counts and mounting styles. The series supports various termination methods and contact materials to accommodate diverse design specifications. The 306-018-421-108 specifically addresses needs for high-density dual-row connections in rugged industrial environments.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 306 Series Ordering Guide for direct substitutes with different position counts or termination types. Cross-reference compatible parts from other manufacturers only if they match the exact 3.96mm pitch and dual female configuration.
