Pomona Electronics 73046 TNC to N Coaxial Adapter

Part Overview

The Pomona Electronics 73046 is a coaxial connector adapter that converts between TNC Plug (male pin) and N Jack (female socket) configurations. This adapter operates at 50 Ohms impedance with a maximum frequency rating of 11 GHz, making it suitable for RF applications requiring impedance-matched connections between these two connector series.

The 73046 is classified as Obsolete. Locating direct replacements from current manufacturing sources is necessary for new procurement and ongoing system support. Active substitute parts are available from alternative manufacturers with identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Pomona Electronics 73046 is determined by strict equivalence across the following critical parameters:

• Adapter configuration: Plug to Jack conversion between N and TNC series
• Connector gender: TNC male pin converting to N female socket
• Impedance: 50 Ohms
• Frequency rating: 11 GHz maximum
• Physical style: Straight, free-hanging in-line mounting
• Fastening mechanism: Threaded connections on both ends
• Material composition: Brass body with nickel finish, phosphor bronze center contact, PTFE dielectric
• Contact plating: Gold
• Mating cycle rating: 500 cycles
• Regulatory compliance: ROHS3 Compliant

The Amphenol RF 242131 meets all these criteria and qualifies as a direct substitute.

Parameter Comparison
