Edgeboard Connectors Procurement Notes

Verify the specific part number against official EDAC documentation to confirm availability and compliance with RoHS standards. Ensure that the ordering suffix matches the required flange and termination specifications. Confirm that the supplier provides valid traceability documents. Check for any recent product lifecycle changes or obsolescence notices directly from the manufacturer before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a high-density, dual-edge connection is required for PCBs with a standard .062" thickness. The 136-position count suits complex signal processing or power distribution needs. Verify that the operating temperature range aligns with the system's thermal profile. Ensure the mounting style and board thickness constraints are compatible with the connector's physical design parameters.

Edgeboard Connectors Part Context

This model belongs to the EDAC 845 Series, characterized by high-temperature capabilities and durable materials. The series utilizes DAP insulators and gold-plated contacts for long-term reliability in critical applications. The 845-136 variant specifically addresses high-pin-count requirements within the standard .100" pitch family, balancing density with mechanical robustness for industrial use cases.

Edgeboard Connectors Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-reference with other EDAC series only if pinout and mechanical dimensions match exactly. Verify compatibility with existing board layouts and mating card specifications before considering alternative sources.
