301-120-520-201

Edgeboard Connectors Overview

The EDAC Inc. 301-120-520-201 is a dual-edge female card edge connector from the 301 series, designed for standard PCB applications. It features 120 positions with a 0.050" (1.27mm) contact spacing and two rows of contacts. The connector utilizes gold-plated copper alloy terminals and a brown polyamide (PA66) insulator. It supports board thicknesses between 0.051" and 0.071" (1.30mm to 1.80mm). Operating temperature ranges from -55°C to 85°C. The component is RoHS3 compliant and classified under MSL Level 1.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration with 120 total positions

• Brown PA66 insulator material ensuring thermal stability
• Standard press-fit termination method for secure mounting

Edgeboard Connectors Applications

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

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix matches the required pin count and plating thickness. Confirm that the package quantity aligns with production needs, as distributors may list varying reel sizes. Ensure the manufacturer part number corresponds exactly to the 301 series specifications before finalizing purchase orders to avoid compatibility issues.

Edgeboard Connectors Selection Notes

Select this connector when a 0.050" pitch dual-edge interface is required for standard thickness boards. The 120-position count suits moderate-density applications. Consider the -55°C to 85°C operating range for environmental suitability. Verify that the brown insulator color meets aesthetic or identification requirements for the assembly.

Edgeboard Connectors Part Context

This component belongs to EDAC's 301 series of standard card edge connectors. The series is characterized by its 0.050" (1.27mm) spacing and robust construction for general-purpose electronic assemblies. The 301 series offers various position counts to accommodate different signal routing densities in compact form factors.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 301-150-520-201 for higher density needs. Cross-series alternatives like 391 or 746 offer different pitches or termination styles but require mechanical re-evaluation.
