Edgeboard Connectors Procurement Notes

Verify that the specific order matches the 305-018-500-268 designation, as the 305 series includes variants with different position counts and termination styles. Confirm compatibility with the target PCB thickness of 1.57 mm and verify that the solder lug termination aligns with the assembly process. Ensure environmental ratings meet the operational temperature extremes required for the intended deployment scenario.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with a 3.96 mm pitch is required for vertical panel mounting. The choice is appropriate for designs necessitating gold-plated contacts for enhanced conductivity and durability. Consider the 18-position count relative to circuit density needs and ensure the thermoplastic housing meets mechanical constraints. Validate that the solder lug termination method fits the manufacturing workflow.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series, which offers various mounting options and row configurations. The series is characterized by its 3.96 mm pitch and compatibility with standard card edge boards. Other models in the family differ primarily in position count and termination style, such as solder pins or eyelets, while maintaining consistent electrical ratings and housing materials.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the 305 series include models like 305-018-555-208, which shares similar electrical characteristics but may differ in termination style. Verify dimensional compatibility and pinout alignment before substitution. Cross-reference specifications to ensure equivalent current ratings and temperature ranges are maintained in any replacement scenario.
