305-072-556-503

Edgeboard Connectors Overview

The EDAC Inc. 305-072-556-503 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 72 positions with a 3.96 mm (0.156 inch) pitch and supports two rows of contacts. The connector utilizes copper alloy contacts with gold plating to ensure reliable signal transmission. It is rated for 5 A current and operates within a temperature range of -40°C to +105°C. The housing is constructed from green thermoplastic polyester, providing an insulation resistance of 5 GOhms. Termination is achieved via solder pins for secure PCB mounting.

Edgeboard Connectors Feature Summary

• Dual-edge female connector configuration for non-specified card types
• Gold-plated copper alloy contacts for enhanced conductivity
• Thermoplastic polyester housing material for durability
• Solder pin termination method for stable PCB attachment

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Communication equipment backplanes
• Automotive electronic modules
• Test and measurement instrumentation

Edgeboard Connectors Procurement Notes

Verify the complete part number including suffixes to ensure correct contact finish thickness and flange specifications. Confirm that the target application requires a dual-edge connector design rather than single-edge variants. Check RoHS compliance status against specific regional regulatory requirements before finalizing procurement orders. Ensure compatibility with the intended card thickness range during mechanical integration planning.

Edgeboard Connectors Selection Notes

Select this component when a high-density connection with 72 positions is required on a dual-edge board. The 3.96 mm pitch offers a balance between signal density and spacing reliability. Consider the 5 A current rating for power distribution needs within the system architecture. The operating temperature range suits environments subject to moderate thermal variations without active cooling.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series provides various position counts and mounting styles for diverse electronic assembly needs. The 305 series is characterized by its use of thermoplastic materials and standardized pitch dimensions. This specific model represents a mid-range position count option within the broader product family.

Edgeboard Connectors Replacement Considerations

Consult official EDAC documentation for direct cross-reference part numbers. Verify mechanical footprint and electrical ratings match exactly before substituting. Generic equivalents may lack the specific gold plating thickness or material composition.
