305-040-500-203

Edgeboard Connectors Overview

The EDAC Inc. 305-040-500-203 is a standard card edge connector from the 305 Series, designed for vertical panel mounting applications. It features a dual female configuration with 40 positions arranged in two rows. The connector utilizes a 0.156-inch (3.96 mm) pitch and accepts board thicknesses ranging from 0.054 to 0.070 inches (1.37 mm to 1.78 mm). Constructed with copper alloy contacts featuring gold plating, it ensures reliable signal transmission. The housing is made of green thermoplastic polyester, providing durability across an operating temperature range of -40°C to +105°C.

• Dual row female contact configuration for high-density interconnects
• Gold-plated copper alloy contacts ensuring corrosion resistance and conductivity
• Thermoplastic polyester insulator supporting wide thermal operating ranges

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interfaces
• Test and measurement instrument modules
• Embedded computing system expansions

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact pin count, plating thickness, and insulation color variations. Ensure compatibility with target PCB edge thickness specifications before integration. Confirm RoHS compliance status through current manufacturer declarations as regulatory requirements may evolve. Cross-reference ordering guides for alternative series options if dimensional constraints differ.

Edgeboard Connectors Selection Notes

Select this component when vertical panel mounting is required for robust mechanical stability in high-vibration environments. The dual-row layout supports higher channel counts compared to single-row alternatives within the same pitch constraint. Verify that the target application operates within the specified -40°C to +105°C temperature range. Consider the flange diameter for panel cutout requirements during mechanical design phases.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, a line of standard card edge connectors known for their versatility in industrial and commercial electronics. The series offers various position counts and mounting styles to accommodate diverse board-to-board and board-to-panel connection needs. The 305-040 variant specifically addresses applications requiring forty signal paths with standardized spacing.

Edgeboard Connectors Replacement Considerations

Consult the official EDAC 305 Series Ordering Guide for direct cross-references. Potential substitutes include variants with identical pitch but different position counts or mounting angles. Verify mechanical footprint and electrical ratings match before substitution.
