Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Amphenol Aerospace or authorized distributors before procurement. Confirm that the crimp tooling matches the specified contact sizes. Ensure environmental sealing requirements align with the connector's IP rating for the intended application. Check for any specific ordering suffixes required for unique material or plating options.

Selection Notes

Select this component when a MIL-DTL-26482 Series II standard is mandated for the system architecture. The 18-position count and size 14 shell must match the mating connector and panel cutout specifications. Verify that the 7.5 A current rating satisfies the circuit load requirements. Ensure the crimp termination process is compatible with the available wire gauges and the gold-plated contact interface.

Part Context

This connector is part of the broader Amphenol Aerospace portfolio focused on high-performance interconnect solutions for commercial and defense markets. The product line emphasizes weight reduction and simplified installation for airframe power distribution and controls. It serves as a critical link in maintaining signal integrity within complex aircraft electronic systems.

Replacement Considerations

Compatible substitutes include other manufacturers producing MIL-DTL-26482 Series II connectors with identical shell sizes and contact arrangements. Cross-reference part numbers such as those from ITT Cannon or Glenair that adhere to the same military specification standards. Ensure mechanical dimensions and electrical ratings remain equivalent.
