Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 305 Series Ordering Guide to confirm exact pin count, plating specifications, and mechanical dimensions. Ensure compatibility with target PCB thickness standards before procurement. Cross-reference the DigiKey or Mouser part number alias to avoid sourcing errors during acquisition.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge interface with 46 positions is required. Confirm that the 0.156-inch pitch aligns with the system's routing density needs. Verify that the through-hole mounting style matches the assembly process capabilities. Check that the thermal rating meets the operational environment requirements.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and configurations for diverse interconnect needs. The 305-046 variant specifically addresses applications requiring moderate density connections with robust mechanical retention and electrical stability.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes with different pin counts or row spacings. Verify that any alternative maintains the same 0.156-inch pitch and dual-edge female configuration to ensure mechanical fit.
