Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm contact configuration and flange characteristics. Ensure the target application accommodates the specified 0.156-inch pitch and compatible PCB thickness range of 0.054 to 0.070 inches before finalizing procurement.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with 0.156-inch spacing is required. Confirm that the mating PCB thickness falls within the 0.054 to 0.070-inch specification. Verify that the through-hole mounting style aligns with the assembly process and that the 34-position count meets the interface 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 termination options, utilizing a consistent 0.156-inch contact spacing architecture. The 305 series is engineered for high-reliability applications requiring durable mechanical retention and stable electrical connections.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants sharing the same 0.156-inch pitch and 34-position count. Verify identical flange features and termination types to ensure mechanical compatibility without redesigning the mounting structure.
