305-070-520-201

Edgeboard Connectors Overview

The EDAC Inc. 305-070-520-201 is a standard card edge connector from the 305 series, designed for high-reliability interconnection applications. It features a dual-row configuration with 70 positions and a pitch of 3.96 mm (0.156 inches). The connector supports PCB thicknesses ranging from 1.37 mm to 1.78 mm and utilizes gold-plated copper alloy contacts for corrosion resistance. Rated for 5 A continuous current, it operates within a temperature range of -40°C to +105°C. The housing is constructed from green thermoplastic polyester, ensuring stability in demanding environments.

Edgeboard Connectors Feature Summary

• Dual-row female contact configuration for double-sided card edge interfaces
• Gold-plated copper alloy contacts ensure reliable signal transmission and corrosion resistance
• Thermoplastic polyester insulation provides structural integrity across wide temperature ranges
• Accepts between-contact and in-contact polarizing keys for secure alignment

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted connections
• Telecommunications equipment utilizing standardized card edge modules
• Automotive electronics needing high-current reliability in harsh environments
• Test and measurement instrumentation with frequent board insertion cycles

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's official ordering guide to confirm exact pin count, termination style, and plating specifications. Ensure compatibility with target PCB thickness and polarizing key requirements before procurement. Cross-reference RoHS and REACH compliance status with current regulatory standards. Confirm availability through authorized distributors to avoid counterfeit components.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 70-position interface with 3.96 mm pitch is required. Consider the 5 A current rating and -40°C to +105°C operating range for environmental suitability. Evaluate the need for polarizing key acceptance if mechanical locking is necessary. Compare against alternative series if different termination styles or housing materials are preferred for specific assembly processes.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, widely used in industrial and commercial electronics. The series offers various position counts and termination options to accommodate diverse design needs. The 305-070 variant specifically addresses applications requiring higher density connections while maintaining the established reliability and performance characteristics of the broader family.

Edgeboard Connectors Replacement Considerations

Direct substitutes may include other EDAC 305 series parts with identical pitch and row configuration but different position counts. Verify mechanical dimensions and electrical ratings before substitution. Alternative manufacturers may offer similar connectors, but pin-to-pin compatibility must be confirmed via detailed datasheet comparison.
