Edgeboard Connectors Procurement Notes

Verify the specific pin count and pitch against the target PCB design, as the 305 series includes variants with different spacings. Confirm that the thermal rating meets the operational environment requirements. Ensure the panel mounting style aligns with the mechanical assembly constraints. Cross-reference the manufacturer part number to avoid confusion with similar series components.

Edgeboard Connectors Selection Notes

Select this model when a 46-position interface with 2.54 mm spacing is required. Consider the 305 series if vertical panel mounting is preferred over board-edge styles. Evaluate the 5 A current rating against the application's power needs. Check compatibility with the specific PCB thickness and edge profile requirements before finalizing the component choice.
