Edgeboard Connectors Procurement Notes

Verify the specific suffix and revision level against the manufacturer's latest datasheet to ensure compatibility with current production requirements. Confirm that the glass-filled variant matches the mechanical stress expectations of the target application. Cross-reference the pin count and tab configuration to prevent mating errors with existing system components.

Edgeboard Connectors Selection Notes

Select this component when a high-density, dual-row card edge interface is required for PCI Express applications. The 1.00 mm pitch allows for compact board layouts while maintaining signal integrity. Ensure the PCB footprint aligns with the specified surface mount dimensions and that the assembly process supports the required soldering profile for gold-plated contacts.

Edgeboard Connectors Part Context

This part belongs to the PCI Express connector family designed for high-performance computing environments. It serves as a critical interface between the motherboard and expansion cards, facilitating rapid data transfer. The dual-row architecture maximizes connectivity within limited spatial constraints typical of modern electronic devices.

Edgeboard Connectors Replacement Considerations

Direct substitutes include 2388957 variants with compatible pin counts and termination styles. Verify that any replacement maintains the same 98-position layout and 1.00 mm pitch to ensure mechanical and electrical compatibility without redesigning the host PCB.
