Edgeboard Connectors Procurement Notes

Verify the complete part number including suffixes to ensure correct contact finish and housing color specifications. Confirm that the target application board thickness matches the 1.57 mm requirement for proper insertion force and retention. Check regional availability as distribution status may vary by location. Ensure compatibility with existing panel mounting hardware and mating card edge profiles before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a 44-position dual-row interface is required with a 3.96 mm spacing. Consider the 5 A current rating and -40 C to +105 C operating temperature range for environmental suitability. The vertical panel mount design dictates the mechanical layout constraints. Verify that the gold-plated contacts meet the corrosion resistance needs of the specific operational environment compared to alternative finishes.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series of standard card edge connectors, which are engineered for general-purpose electronic interconnection. The series offers various position counts and row configurations to accommodate different circuit density requirements. The 305-044-520-578 specifically addresses applications needing a moderate pin count with robust mechanical mounting characteristics and standardized dimensions for easy integration into larger assemblies.

Edgeboard Connectors Replacement Considerations

Compatible substitutes within the same series include 305-044-520-202 and 305-044-520-504, provided they match the required contact finish and housing specifications. Cross-series replacements require verification of pitch, row count, and mounting style to ensure mechanical and electrical compatibility without redesigning the host assembly.
