• Connector Style: UHF
• Connector Type: Receptacle, Female Socket
• Impedance: 50 Ohms
• Contact Termination: Solder Cup
• Shield Termination: Solder
• Mounting Type: Panel Mount
• Mounting Feature: Bulkhead - Rear Side Nut
• Fastening Type: Threaded
• Frequency - Max: 300 MHz
• Voltage Rating: 500 V
• Mating Cycles: 500
• Center Contact Material: Brass
• Body Material: Brass
• Body Finish: Nickel
• Center Contact Plating: Silver
• Dielectric Material: PTFE
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes for the main part number.

Parameter Comparison

Engineering Selection Recommendations

Both the Amphenol RF 083-875 and the substitute part 83-875-1002 are active products with identical electrical and mechanical specifications. Both components are ROHS3 compliant and REACH affected, meeting current regulatory requirements for electronic component manufacturing and use. The substitute part 83-875-1002 is available in bulk packaging and maintains full parametric equivalence with the main part number across all critical RF, mechanical, and environmental specifications. Selection between these parts is based on packaging requirements and inventory availability rather than technical performance differences.
