306-023-420-112

Overview

The EDAC Inc. 306-023-420-112 is a dual-edge female card edge connector from the 306 series, designed for high-reliability applications. It features 46 positions with a 0.156-inch (3.96mm) contact spacing and accepts printed circuit boards with a thickness of 0.054 to 0.070 inches (1.37 to 1.78mm). The connector utilizes copper alloy contacts with tin plating and a green thermoplastic polyester insulator body. Rated for operation between -40°C and +105°C, it employs a single centerline row configuration and supports panel mount or through-hole solder termination.

Feature Summary

• Dual-edge female design accommodating non-specified board types
• Single centerline row configuration for simplified routing
• Low-profile insulator body constructed from thermoplastic polyester
• Panel mount capability with flush mounting flange

Applications

• High-density electronic interconnect systems
• Industrial control module connections
• Telecommunications equipment backplanes
• Automotive electronics interfaces

Procurement Notes

Verify that the specific order matches the 306-023-420-112 designation, as the 306 series includes variants with different plating such as gold or tin. Confirm the required termination style aligns with the through-hole solder specification. Ensure the application environment remains within the stated temperature range of -40°C to +105°C. Check RoHS compliance status if restricted substances are a concern for the project requirements.

Selection Notes

Select this component when a dual-edge interface with 0.156-inch pitch is required for robust mechanical stability. The thermoplastic polyester housing provides durability in demanding environments. Consider the flush mounting flange feature for secure panel integration. This model is suitable where single-row simplicity reduces assembly complexity while maintaining high pin count density.

Part Context

This part belongs to the EDAC 306 series, which specializes in standard card edge connectors. The series offers various position counts and termination options to suit diverse PCB layout needs. The 306-023-420-112 specifically addresses applications requiring dual-edge connectivity with a standardized 0.156-inch spacing, ensuring compatibility with industry-standard board thicknesses.

Replacement Considerations

Cross-reference with other 306 series parts like 306-023-421-102 for similar form factors but verify plating differences. Ensure substitute components maintain the same 0.156-inch pitch and dual-edge configuration to preserve mechanical fit.
