Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact plating thickness and housing color variations within the 305 series. Confirm that the application environment remains within the specified operating temperature range. Ensure the mating card edge thickness aligns with the connector's mechanical acceptance criteria. Check regional distribution availability as stock levels may vary by region.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with polarizing key capability is required. The 3.96 mm pitch accommodates standard board layouts while maintaining high pin density. Verify that the 5 A current rating meets the circuit load requirements. Consider the vertical panel mount form factor for chassis integration needs.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of edgeboard connectors, which are engineered for robust performance in demanding environments. The series offers various position counts and termination options. The 305-044 variant specifically provides a 44-position interface suitable for complex signal routing applications.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series parts with matching 44 positions and dual row configurations. Verify that alternative models maintain the same 3.96 mm pitch and polarizing key compatibility.
