CT3348 Coaxial Connector Adapter - Equivalent & Substitute Parts
Part Overview
The CT3348 is a coaxial connector adapter designed to convert between BNC Jack (Female Socket) and N Jack (Female Socket) configurations. This adapter operates at 50 Ohms impedance with a maximum frequency rating of 10 GHz, making it suitable for RF applications requiring impedance-matched connections between these two connector series.
The CT3348 is classified as Obsolete. Identifying equivalent substitute parts is necessary to ensure continued availability for maintenance, repair, and new system integration where this adapter specification is required.

Substitute Part Grouping Explanation
Substitution eligibility for the CT3348 is determined by strict equivalence across the following critical parameters:
- Adapter Series: BNC to N conversion capability
- Adapter Type: Jack to Jack configuration
- Center Gender: Female to Female socket orientation
- Impedance: 50 Ohms
- Frequency Rating: 10 GHz maximum
- Insertion Loss: 0.10 dB
- Fastening Type: Bayonet Lock and Threaded mechanisms
- Operating Temperature Range: -55°C to 155°C
- Dielectric Material: PTFE
- Body Material and Finish: Brass with Nickel finish
- Center Contact Plating: Gold
The CT3348A meets all these criteria and is designated as the direct substitute for the obsolete CT3348.
