Edgeboard Connectors Procurement Notes

Verify the complete part number against official EDAC documentation to confirm specific flange characteristics and insulation material properties. Ensure that the required polarizing key type matches the connector's acceptance specifications. Confirm compliance with RoHS3 standards and check for any regional distribution restrictions or availability limitations prior to ordering.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 52-position interface with a 3.96 mm pitch is required. Consider the 5 A current rating and 1800 VACrms dielectric strength for appropriate voltage applications. Evaluate the panel mount vertical orientation and compatible board thickness range of 1.37 mm to 1.78 mm against mechanical design constraints.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 Series, which offers various mounting options and row configurations. The series is characterized by its durable construction and suitability for demanding environments. The specific model integrates thermal plastic polyester insulation and operates within a temperature range of -40°C to 105°C, ensuring stability across diverse operational conditions.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 Series models with matching position counts and pitch dimensions. Verify equivalent electrical ratings and mechanical mounting styles before substitution. Cross-reference part numbers such as 305-050-520-578 or 305-052-520-568 only if they meet all functional and dimensional requirements.
