CT3346 BNC to N Coaxial Adapter Connector
Part Overview
The CT3346 is a coaxial adapter connector that converts between BNC Jack (female socket) and N Plug (male pin) configurations. This straight-style, free-hanging adapter operates at 50 Ohms impedance with a maximum frequency rating of 10 GHz, making it suitable for RF and microwave applications requiring series conversion between BNC and N connector types.
The CT3346 is classified as obsolete. Locating equivalent substitute parts is necessary to ensure continued availability for system maintenance, repair, and new installations where this adapter specification is required.

Engineering Selection Recommendations
The CT3346A is the direct substitute for the obsolete CT3346. Both parts are manufactured by Cal Test Electronics and maintain identical electrical and mechanical specifications across all critical parameters.
The CT3346A carries Active product status, ensuring ongoing availability and supply chain continuity. Both parts maintain ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for current applications.
Selection of the CT3346A over the obsolete CT3346 is appropriate for all new designs and replacement applications requiring BNC to N coaxial adapter functionality at 50 Ohms impedance with 10 GHz maximum frequency operation.
Frequently Asked Questions (FAQ)
Q: Can CT3346A be used as a direct replacement for CT3346?
A: Yes. The CT3346A is a direct substitute. All electrical parameters (impedance, frequency rating, insertion loss, operating temperature range) and mechanical parameters (connector types, gender configuration, fastening method, materials, and finishes) are identical between the two parts.
Q: What is the difference between CT3346 and CT3346A?
A: The primary difference is product status. CT3346 is obsolete, while CT3346A is active. CT3346A is supplied in Box packaging. All functional and performance specifications are equivalent.
Q: Are there any compatibility concerns when substituting CT3346A for CT3346?
A: No compatibility concerns exist. Both parts provide identical BNC Jack (female socket) to N Plug (male pin) conversion with matching impedance, frequency response, and environmental operating range.
Q: What connector types does this adapter support?
A: This adapter converts between BNC Jack (female socket) on one end and N Plug (male pin) on the other end. It is designed for straight, in-line mounting applications.
Q: What is the impedance rating of this adapter?
A: The impedance rating is 50 Ohms, standard for RF and microwave coaxial applications.
Q: What is the maximum operating frequency?
A: The maximum frequency rating is 10 GHz, suitable for RF and microwave signal transmission applications.
Q: What materials are used in the construction?
A: The body is brass with nickel finish. The center contact is beryllium copper and brass with gold plating. The dielectric material is polytetrafluoroethylene (PTFE).
Q: What is the insertion loss specification?
A: The insertion loss is 0.10 dB across the operating frequency range.
Q: What is the operating temperature range?
A: The operating temperature range is -55°C to 155°C, suitable for industrial and military applications.
