Amphenol RF 122395 TNC Connector Plug Equivalent & Substitute Parts

Part Overview

The Amphenol RF 122395 is an active TNC connector plug designed for 50-ohm RF applications. This male pin connector features crimp termination for both center contact and shield, supporting frequencies up to 11 GHz. The connector is configured as a free-hanging (in-line) component suitable for cable assemblies using RG-174, RG-188, RG-188A, RG-316, LMR-100, and M17/119-RG174 cable groups. With 879 pieces in current inventory and ROHS3 compliance, this part remains actively produced. Equivalent substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when specific package configurations are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Amphenol RF 122395 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Style: TNC
• Connector Type: Plug, Male Pin
• Impedance: 50 Ohms
• Contact Termination: Crimp
• Shield Termination: Crimp
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Threaded
• Cable Group Compatibility: RG-174, 188, 188A, 316, LMR-100, M17/119-RG174
• Frequency - Max: 11 GHz
• Voltage Rating: 500 V
• Insertion Loss: 0.18 dB
• RoHS Status: ROHS3 Compliant

The substitute part Amphenol RF 122116 meets all mandatory matching parameters. The primary difference between these parts is the package configuration: the 122395 includes 3 pieces per package (1 Connector, 1 Contact, 1 Ferrule), while the 122116 includes 5 pieces per package (1 Connector, 1 Contact, 1 Ferrule, 1 Insulator, 1 Sleeve). Both parts are electrically and mechanically equivalent for direct substitution in RF applications.

Parameter Comparison

Engineering Selection Recommendations

Both the Amphenol RF 122395 and 122116 are active production parts with ROHS3 compliance and REACH affected status. Selection between these parts should be based on package configuration requirements and inventory availability.

Part 122395 is appropriate when the application requires the minimal package configuration of 3 pieces per unit (connector, contact, and ferrule only).

Part 122116 is appropriate when the application requires the extended package configuration of 5 pieces per unit, which includes additional insulator and sleeve components. This part also offers higher current inventory availability at 1691 pieces compared to 879 pieces for the 122395.

Both parts maintain identical electrical performance characteristics, including 50-ohm impedance, 11 GHz maximum frequency, 0.18 dB insertion loss, and 500 V voltage rating. Both support the same cable group compatibility and feature identical material specifications (brass body with nickel finish, gold-plated brass center contact, and PTFE dielectric).

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 122116 be used as a direct replacement for the 122395?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical connector style, impedance, termination method, frequency rating, and insertion loss specifications. The primary difference is the package configuration, with 122116 including additional insulator and sleeve components.

Q: What is the difference in package contents between these two parts?

A: The 122395 package includes 3 pieces: 1 connector, 1 contact, and 1 ferrule. The 122116 package includes 5 pieces: 1 connector, 1 contact, 1 ferrule, 1 insulator, and 1 sleeve. The additional insulator and sleeve in the 122116 package may be beneficial for certain assembly configurations.

Q: Are both parts suitable for the same cable types?

A: Yes. Both the 122395 and 122116 are compatible with RG-174, RG-188, RG-188A, RG-316, LMR-100, and M17/119-RG174 cable groups.
