Edgeboard Connectors Procurement Notes

Verify the specific suffix code to confirm exact plating thickness, insulation color, and flange characteristics. Ensure the ordering part number matches the required board thickness tolerance and row spacing specifications. Confirm RoHS compliance status and moisture sensitivity level requirements against project standards before procurement.

Edgeboard Connectors Selection Notes

Select this component when a high-density 70-position interface is required for vertical panel installation. The 3.96 mm pitch supports robust connections for industrial environments. Verify that the target PCB thickness aligns with the 1.57 mm nominal specification to ensure proper mechanical retention and electrical contact.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series provides various position counts and termination options for reliable interconnection. The 305-070 variant specifically addresses applications requiring a dual-edge interface with substantial pin density for complex signal routing.

Edgeboard Connectors Replacement Considerations

Cross-reference with other 305-series variants such as 305-070-521-202 or 305-070-521-502 if different plating or housing colors are acceptable. Ensure substitute parts maintain the same 0.156 inch pitch and 70-position count.
