Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact pin count, plating thickness, and flange specifications. Ensure compatibility with the target PCB card thickness range of 1.37 mm to 1.78 mm. Confirm RoHS compliance status if required by project regulations. Cross-reference the part number with the latest EDAC documentation to avoid discrepancies in variant definitions.

Edgeboard Connectors Selection Notes

Select this component when a dual-sided female connector with a 3.96 mm pitch is required for vertical panel mounting. It is suitable for applications needing a 5 A current rating and operation between -40°C and +105°C. Consider the thermoplastic polyester material for environmental resistance. Ensure the mating card fits the specified thickness tolerance for proper mechanical engagement.

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 series is characterized by its semi-bellows contact type and robust construction. It serves as a reliable solution for connecting edge-boarded circuits to system backplanes or panels.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes with different position counts or contact types. Verify that any alternative maintains the 3.96 mm pitch and dual female configuration. Ensure thermal and electrical ratings match the original requirements.
