302-110-221-201

Edgeboard Connectors Overview

The EDAC Inc. 302-110-221-201 is a female card edge connector from the 302 series, designed for dual-edge board applications. It features 110 positions with a 0.050 inch (1.27mm) pitch and two rows of contacts. The connector utilizes gold-plated cantilever spring contacts mounted on a black polyamide (PA66) insulator. It supports PCB thicknesses between 0.051 and 0.071 inches and operates within a temperature range of -55°C to 85°C.

Edgeboard Connectors Feature Summary

• Dual-edge configuration accommodates non-specified double-sided circuit boards
• Cantilever spring contacts ensure reliable electrical connection
• Gold plating provides corrosion resistance and low contact resistance
• Polyamide insulation offers thermal stability and mechanical strength

Edgeboard Connectors Applications

• High-density electronic module interconnections
• Industrial control system backplanes
• Telecommunications equipment signal routing
• Automotive electronics interface modules

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 110-position dual-edge specification. Confirm compatibility with the target PCB thickness range of 0.051 to 0.071 inches. Ensure the operating environment falls within the -55°C to 85°C temperature limits. Check for RoHS3 compliance requirements if applicable to the final assembly standards.

Edgeboard Connectors Selection Notes

Select this component when high pin density is required in a compact footprint. The 0.050-inch pitch allows for significant I/O count in limited space. Choose this model over single-edge variants for applications requiring connections on both sides of the substrate. Consider the mounting style and termination method to ensure alignment with the assembly process.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 302 series, which specializes in high-reliability card edge solutions. The series is characterized by its robust construction and consistent performance across various industrial environments. Similar models in the family vary primarily in position count and pitch dimensions while maintaining the same fundamental design architecture.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 302 series connectors with equivalent pin counts and pitch specifications. Cross-brand replacements require careful verification of dimensional tolerances and contact force characteristics to ensure functional equivalence without modifying the host board layout.
