Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC 305 Series Ordering Guide to ensure correct pitch, row spacing, and mounting hole specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into production assemblies. Cross-reference the part number with current manufacturer documentation to validate availability and lead times through authorized distribution channels.

Edgeboard Connectors Selection Notes

Select this model when a dual-edge female connector is required for vertical panel mounting applications. Ensure the target printed circuit board thickness aligns with the specified 0.062-inch nominal requirement. Verify that the system environment remains within the -40°C to +105°C operating temperature range. Confirm that the 0.156-inch contact spacing meets the design layout constraints for the associated edge card.
