Key Parameters

Substitute Part Grouping Explanation

The 16_TNC-50-3-112/133_NE from Huber+Suhner, Inc. qualifies as a parametric equivalent based on the following critical parameters:

• Connector Style: TNC (identical interface standard)
• Connector Type: Plug, Male Pin (identical mating configuration)
• Impedance: 50 Ohms (identical electrical characteristic)
• Contact Termination: Solder (identical termination method)
• Shield Termination: Crimp (identical shielding method)
• Mounting Type: Free Hanging (In-Line), Right Angle (identical mechanical orientation)
• Cable Group: RG-58 (identical cable compatibility)
• Fastening Type: Threaded (identical coupling mechanism)
• Frequency - Max: 11 GHz (identical frequency rating)
• Number of Ports: 1 (identical port count)
• Center Contact Material: Brass (identical material)
• Body Material: Brass (identical material)
• Center Contact Plating: Gold (identical plating)
• Mating Cycles: 500 (identical mechanical durability rating)

These parameters define the functional and mechanical compatibility required for direct substitution in RF coaxial connector applications.

Parameter Comparison

Engineering Selection Recommendations

Both the VT20-2051 and 16_TNC-50-3-112/133_NE are active production parts with identical electrical and mechanical specifications for TNC 50 Ohm RF connector applications. Selection between these parts should be based on:

• Availability: VT20-2051 has 1033 units in stock; 16_TNC-50-3-112/133_NE has 856 units in stock
• Operating temperature range: The Huber+Suhner part supports -65°C ~ 165°C versus -55°C ~ 85°C for the Cinch part, providing extended thermal capability
• Regulatory compliance: Both parts are EAR99 classified and share identical HTSUS coding
• Dielectric material: The Huber+Suhner part uses PFA/PTFE dielectric versus POM in the Cinch part, affecting thermal and chemical resistance properties

Frequently Asked Questions (FAQ)

Q: Can the 16_TNC-50-3-112/133_NE directly replace the VT20-2051 in existing designs?

A: Yes. Both connectors share identical TNC interface specifications, 50 Ohm impedance, solder contact termination, crimp shield termination, right angle free hanging mounting, RG-58 cable compatibility, threaded fastening, 11 GHz frequency rating, and 500 mating cycle rating. The connectors are mechanically and electrically interchangeable.

Q: What are the differences between these two parts?

A: The primary differences are body finish (Nickel versus White Bronze), dielectric material (POM versus PFA/PTFE), and operating temperature range (-55°C ~ 85°C versus -65°C ~ 165°C). The Huber+Suhner part offers extended thermal operating range and alternative dielectric composition.

Q: Are there packaging differences between these parts?

A: Both parts are supplied in bulk packaging. The VT20-2051 includes 3 pieces per connector (1 connector, 1 end cap, 1 ferrule). The 16_TNC-50-3-112/133_NE does not specify included accessories.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts are classified as EAR99 and share the same HTSUS code (8536.69.4010). Both are active production parts with no moisture sensitivity level restrictions.

Q: Which part should be selected for high-temperature applications?

A: The 16_TNC-50-3-112/133_NE supports operating temperatures up to 165°C, compared to 85°C for the VT20-2051, making it suitable for elevated temperature environments.
