305-050-500-203

Edgeboard Connectors Overview

The EDAC Inc. 305-050-500-203 is a standard card edge connector featuring 50 positions in a dual female configuration. It utilizes a 3.96 mm (0.156 inch) pitch and accepts PCBs with thicknesses ranging from 1.37 mm to 1.78 mm. The contacts are constructed from copper alloy with gold plating, ensuring reliable signal transmission. Designed for panel mounting, this component operates within a temperature range of -40°C to +105°C and is housed in a green thermoplastic polyester insulator.

Edgeboard Connectors Feature Summary

• Dual row female contact configuration for non-specified card edge applications
• Gold-plated copper alloy contacts for enhanced conductivity and corrosion resistance
• Thermoplastic polyester insulation providing stability across wide temperature ranges
• Panel mount installation style with vertical orientation

Edgeboard Connectors Applications

• Industrial control system interconnections
• Telecommunications equipment backplanes
• Test and measurement instrument interfaces
• General-purpose electronic module connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact pin count, contact finish, and mounting style compatibility. Ensure that the target PCB thickness falls within the specified acceptance range of 1.37 mm to 1.78 mm. Confirm that the application environment remains within the rated operating temperature limits of -40°C to +105°C to maintain performance integrity.

Edgeboard Connectors Selection Notes

Select this model when a dual-row interface with a 3.96 mm pitch is required for robust panel-mounted connections. The gold-plated contacts offer superior durability compared to tin finishes in high-cycle environments. Consider the vertical mounting profile and thermoplastic housing material for thermal management and mechanical stability in dense assembly layouts.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series provides various position counts and mounting options designed for reliable board-to-board or board-to-panel connections. The 305 series is characterized by its durable construction and consistent electrical performance across diverse industrial and commercial applications.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series variants such as 305-050-556-502, provided the physical dimensions and contact specifications align with the design requirements.
