305-050-555-201

Edgeboard Connectors Overview

The EDAC Inc. 305-050-555-201 is a dual-edge female card edge connector designed for board-to-board interconnection. It features 50 positions arranged in two rows with a 0.156-inch (3.96mm) contact spacing. The connector utilizes gold-plated copper alloy contacts and a green thermoplastic insulator body. It supports solder termination and accommodates printed circuit boards with thicknesses ranging from 0.054 to 0.070 inches. The component operates within a temperature range of -40°C to +105°C and complies with RoHS3 standards.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration for secure mating with specified card edge profiles
• Gold-plated contacts ensure reliable signal transmission and corrosion resistance
• Thermoplastic insulator provides structural integrity and electrical isolation
• Solder termination facilitates permanent mounting on target PCBs

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interfaces
• Computing hardware expansion slots
• Test and measurement instrument modules

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current catalog to confirm exact pin count, row configuration, and termination style. Ensure compatibility with the target PCB thickness specifications before procurement. Cross-reference the component revision history to guarantee adherence to current environmental compliance requirements such as RoHS3. Confirm that the supplier source is authorized to prevent counterfeit components.

Edgeboard Connectors Selection Notes

Select this connector when a dual-edge female interface is required for 50-position applications. Verify that the target PCB thickness falls within the 0.054 to 0.070 inch acceptance range. Ensure the mating card edge profile matches the non-specified dual-edge requirement. Confirm that the operating environment remains within the -40°C to +105°C thermal limits defined by the thermoplastic material properties.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options for diverse electronic assembly needs. The 305-050 variant specifically addresses medium-density interconnection requirements. It serves as a critical interface element in modular electronic systems requiring robust mechanical and electrical connections.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series connectors with identical 50-position dual-edge female configurations. Verify that alternative part numbers maintain the same 0.156-inch pitch and compatible PCB thickness range. Ensure replacement units match the original solder termination type and gold plating specifications.
