Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm exact plating thickness, housing color, and flange specifications. Ensure compatibility with target PCB board thickness limits before procurement. Confirm RoHS compliance status through current manufacturer datasheets as regulatory requirements may evolve over time.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 42-position card edge interface is required for vertical panel integration. The 3.96 mm pitch accommodates standard edge card layouts. Verify that the operating environment remains within the specified -40°C to +105°C thermal range and that the mating board thickness falls within the 1.37 mm to 1.78 mm acceptance window.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which provides engineered solutions for power connection and signal communication between mother, daughter, and extender boards. The series is widely utilized in industrial, medical, and energy sectors requiring robust interconnects. EDAC specializes in card edge and rack & panel technologies for diverse market applications.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants such as 305-042-520-202 for similar form factors. Ensure any substitute matches the 42-position count, 3.96 mm pitch, and dual-row architecture. Verify identical mounting style and thermal ratings before implementation.
