Procurement Notes

Verify the exact manufacturer part number against official Amphenol documentation, as cross-references like JT06RE-20-39SA(304) indicate potential confusion with similar MIL-DTL-38999 series components. Confirm that the specific suffix denotes the correct contact type and plating. Ensure the procurement source provides valid traceability certificates. Check for any obsolescence notices or lifecycle status updates directly from the manufacturer before finalizing orders.

Selection Notes

Select this component when a straight-mount cable plug with socket contacts is required for MIL-DTL-26482 applications. The 41-position count and size 20 shell dictate the physical space requirements. Verify that the mating receptacle matches the pin configuration and insertion arrangement. Consider the solder termination requirement for PCB or harness assembly processes. Ensure environmental sealing needs align with the connector's inherent design capabilities.

Part Context

This component belongs to the broader family of circular MIL-spec connectors manufactured by Amphenol Aerospace. These connectors are engineered for high-reliability applications in aerospace and defense sectors. The specific model integrates standard military interface dimensions with durable materials to withstand vibration and harsh conditions. It serves as a critical interconnect point within complex wiring harnesses, ensuring signal integrity across various electronic subsystems.

Replacement Considerations

MS3116F20-41SW is a verified equivalent offering identical 41-position, size 20 straight plug specifications with socket contacts and solder termination. Both parts adhere to MIL-DTL-26482 standards. Verify dimensional compatibility and mating interface alignment before substitution. Ensure material specifications for contacts and shells meet the original design requirements.
