306-012-421-158

Edgeboard Connectors Overview

The EDAC Inc. 306-012-421-158 is a dual-edge card edge connector designed for panel mount applications using through-hole solder termination. It features 24 positions arranged in two rows of 12 contacts, with a 0.156-inch (3.96mm) pitch. The connector utilizes female cantilever contacts with tin plating and green thermoplastic polyester insulation. It accommodates board thicknesses between 0.054 and 0.070 inches and operates within a temperature range of -40°C to 105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female contact configuration for secure board insertion

Edgeboard Connectors Procurement Notes

Verify the specific pin count and pitch against the target PCB layout before ordering. Confirm that the mating card thickness falls within the specified mechanical tolerance range. Ensure the soldering process parameters are compatible with the tin-plated terminal finish and the thermal limits of the polyester insulator. Check for RoHS compliance requirements if applicable to the final assembly environment.

Edgeboard Connectors Selection Notes

Select this model when a dual-edge connection with a 0.156-inch pitch is required for panel-mounted installations. The through-hole solder termination method provides robust mechanical stability compared to surface mount alternatives. Consider the operating temperature range and material compatibility with the mating card substrate. This series offers standardized dimensions for easy integration into existing chassis designs.

Edgeboard Connectors Part Context

This component belongs to the EDAC 306 Series, which specializes in high-reliability card edge connectors. The series is characterized by its versatile mounting options and durable contact materials suitable for demanding environments. The 306 line supports various pin counts and configurations, allowing engineers to scale connectivity solutions while maintaining consistent mechanical interfaces across different product lines.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 306 series variants for alternative pin counts or termination styles. Verify mechanical footprint compatibility if substituting with connectors from different manufacturers. Ensure that any replacement part maintains the same pitch and contact type to guarantee proper mating with the existing PCB design.
