Procurement Notes

Verify the exact suffix designation against the manufacturer's latest datasheet to confirm plating thickness and environmental sealing ratings. Ensure compatibility with mating receptacles regarding shell size and contact arrangement. Confirm supply chain authenticity through authorized distributors to prevent counterfeit components in critical aerospace applications.

Selection Notes

Select this component when a high-density 68-position circular connector is required for MIL-DTL-38999 environments. The 18-shell size offers a balance between contact count and physical footprint. Verify that the application requires a male pin configuration and straight cable entry. Consider the operating temperature range and current rating against specific circuit demands before finalizing the selection.

Part Context

This part belongs to the Amphenol JT06 series, which complies with MIL-DTL-38999 standards. The series is widely used in aerospace and defense sectors for its durability and performance in extreme conditions. The 71-418618-68Y identifier links directly to the commercial equivalent JT06RE-18-68PD(301), ensuring interchangeability within compatible system architectures.

Replacement Considerations

Direct substitutes include JT06RE-18-68PD(301). Cross-referencing with other manufacturers' MIL-DTL-38999 Series III connectors may be possible if dimensional and electrical specifications match exactly. Always verify contact arrangement and coupling style before substitution.
