APH-SMAJ-TNCP Equivalent & Substitute Parts

Part Overview

The APH-SMAJ-TNCP is a coaxial adapter connector manufactured by Amphenol RF that converts between SMA Jack (female socket) and TNC Plug (male pin) configurations. This straight-style, free-hanging adapter operates at 50 Ohms impedance with a maximum frequency rating of 11 GHz and supports operating temperatures from -65°C to 165°C.

The APH-SMAJ-TNCP is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system compatibility and ensure continued availability for applications requiring SMA to TNC conversion functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the APH-SMAJ-TNCP must satisfy the following criteria to ensure functional equivalence:

Critical Substitution Parameters:

• Adapter Series: SMA to TNC conversion capability
• Center Gender: Female to Male configuration
• Impedance: 50 Ohms
• Style: Straight orientation
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Threaded connections
• Frequency - Max: 11 GHz or greater
• Operating Temperature Range: -65°C to 165°C or broader
• Body Material: Brass construction
• Dielectric Material: PTFE

The substitute part 242105 satisfies all critical parameters. While the conversion direction is reversed (TNC Plug to SMA Jack versus SMA Jack to TNC Plug), both parts provide equivalent SMA-to-TNC interconnection capability with identical electrical and mechanical specifications. The reversal of conversion direction does not affect functional compatibility in applications requiring bidirectional adapter functionality.
