Amphenol RF 901-168 SMA to TNC Coaxial Adapter Connector

Part Overview

The Amphenol RF 901-168 is an active, in-stock coaxial adapter connector that converts between SMA plug and TNC plug 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 adapter features gold-plated center contacts and PTFE dielectric material for reliable RF signal transmission. Equivalent substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when project requirements necessitate alternative manufacturer specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Amphenol RF 901-168 are identified based on strict equivalence of core electrical and mechanical parameters. The substitution criteria are:

Critical Matching Parameters:

• Adapter Type: Plug to Plug
• Conversion Type: Between Series (SMA to TNC)
• Center Gender: Male to Male
• Impedance: 50 Ohms
• Style: Straight
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Threaded, Threaded
• Dielectric Material: Polytetrafluoroethylene (PTFE)
• Operating Temperature Range: -65°C ~ 165°C

The Pomona Electronics 4292 meets all critical matching parameters and qualifies as a direct substitute. Both parts maintain identical functional specifications for SMA plug to TNC plug conversion with matching impedance, mounting configuration, and operating temperature range. Variations in frequency maximum rating (11 GHz versus 12.4 GHz) and material composition do not preclude substitution when the application frequency requirement does not exceed 11 GHz.

Parameter Comparison

Engineering Selection Recommendations

Both the Amphenol RF 901-168 and Pomona Electronics 4292 are active products with ROHS3 compliance and equivalent functional specifications for SMA to TNC plug-to-plug conversion. Selection between these parts is based on availability and application frequency requirements.

Amphenol RF 901-168 is the primary specification with 1003 units in stock and a maximum frequency rating of 11 GHz. This part is suitable for applications operating at or below 11 GHz.

Pomona Electronics 4292 is a qualified substitute with 790 units in stock and a maximum frequency rating of 12.4 GHz. This part provides extended frequency capability and is suitable for applications requiring operation up to 12.4 GHz. Both parts maintain identical impedance, mounting configuration, and operating temperature specifications.

Selection should be based on application frequency requirements and component availability at the time of procurement.

Frequently Asked Questions (FAQ)

Q: Can the Pomona Electronics 4292 be used in place of the Amphenol RF 901-168?

A: Yes. Both parts are plug-to-plug SMA to TNC adapters with identical 50-ohm impedance, straight configuration, and operating temperature range of -65°C to 165°C. The Pomona part provides extended frequency capability (12.4 GHz versus 11 GHz) and is functionally equivalent for applications operating within the 11 GHz specification.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution eligibility is determined by matching adapter type (plug to plug), conversion series (SMA to TNC), center gender (male to male), impedance (50 ohms), style (straight), mounting type (free hanging in-line), fastening type (threaded), dielectric material (PTFE), and operating temperature range (-65°C to 165°C).

Q: Are there differences in material composition between these adapters?

A: Yes. The Amphenol RF 901-168 specifications do not detail body material or center contact material. The Pomona Electronics 4292 features a beryllium copper body with gold finish and brass center contact material. These material differences do not affect functional equivalence for the specified electrical and mechanical parameters.

Q: What is the packaging format for both parts?

A: Both parts are supplied in bulk packaging format.

Q: Do both parts meet environmental compliance requirements?

A: Yes. Both the Amphenol RF 901-168 and Pomona Electronics 4292 are ROHS3 compliant. The Amphenol part is REACH affected, while the Pomona part is REACH unaffected.

Q: What is the moisture sensitivity level for these adapters?

A: The Amphenol RF 901-168 has a Moisture Sensitivity Level (MSL) of 1 (Unlimited). The Pomona Electronics 4292 has MSL listed as Not Applicable.
