Engineering Selection Recommendations

Both the Amphenol RF 142193-75 and TE Connectivity AMP Connectors 414048-6 are active production parts with full ROHS3 compliance and REACH compliance status. Selection between these parts is based on the following engineering considerations:

Amphenol RF 142193-75 is suitable for applications requiring the included accessory package (end cap, ferrule, heat shrink). Current inventory of 951 units supports immediate availability for high-volume deployments.

TE Connectivity AMP Connectors 414048-6 is suitable for applications where bulk packaging is preferred. Current inventory of 1,094 units provides alternative sourcing with equivalent electrical and mechanical performance. This part is supplied without the accessory package included with the Amphenol part.

Both parts satisfy identical electrical performance requirements, temperature operating ranges, voltage ratings, and RF frequency specifications. Selection should be based on packaging requirements, inventory availability, and supply chain strategy.
