Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required flange configurations and termination styles. Confirm that the selected variant matches the intended board thickness and mounting orientation. Cross-reference the manufacturer datasheet for precise mechanical dimensions and electrical ratings before finalizing procurement decisions to avoid integration issues.

Edgeboard Connectors Selection Notes

Select this connector when high-temperature stability and durable gold plating are critical for long-term performance. The dual-edge design accommodates complex circuit boards requiring numerous connections. Ensure the application environment falls within the specified -40°C to +125°C operating range and that the mounting style aligns with the threaded insert feature provided by this specific model.

Edgeboard Connectors Part Context

This component belongs to EDAC's 845 High Temperature Series, which specializes in connectors capable of withstanding extreme thermal conditions. The series is widely utilized in sectors where standard connectors might fail due to heat or harsh environmental factors. The 845-118-521-208 specifically offers a high pin count solution for dense packaging requirements while maintaining structural integrity under stress.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include models with identical pitch and position counts but different flange options. Verify that any replacement maintains the 0.100 inch pitch and dual female contact type. Check for equivalent material specifications, particularly the DAP insulation and gold plating thickness, to ensure functional parity.
