Amphenol RF 132333 SMA Connector Jack Equivalent & Substitute Parts

Part Overview

The Amphenol RF 132333 is an SMA connector jack (female socket) rated for 50 ohms impedance with crimp termination. This panel mount coaxial connector is designed for RF applications up to 12.4 GHz and operates across a temperature range of -65°C to 165°C. The part is currently active in production and ROHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical specifications are required for component sourcing, inventory management, or design flexibility while maintaining RF performance and connector compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Amphenol RF 132333 are qualified based on the following critical parameters that determine functional equivalence:

Electrical Equivalence Criteria:

• Connector style: SMA
• Connector type: Jack, Female Socket
• Impedance: 50 Ohms
• Frequency maximum: 12.4 GHz
• Dielectric material: Polytetrafluoroethylene (PTFE)

Mechanical Equivalence Criteria:

• Mounting type: Panel Mount
• Mounting feature: Bulkhead - Front Side Nut
• Fastening type: Threaded
• Number of ports: 1
• Operating temperature range: -65°C ~ 165°C
• Mating cycles: 500

Termination Compatibility:

• Shield termination: Crimp
• Contact termination: Crimp (primary) or Crimp/Solder (acceptable for substitution)

The substitute parts Cinch Connectivity Solutions 142-0303-411 and 142-0303-416 meet all critical electrical and mechanical parameters. Variations in housing color, body finish, center contact material, and cable group compatibility do not affect the core RF performance or panel mount functionality of the connector.

Parameter Comparison

Engineering Selection Recommendations

All three parts—Amphenol RF 132333, Cinch 142-0303-411, and Cinch 142-0303-416—are active production components with ROHS3 compliance and REACH affected status. They share identical electrical performance specifications for RF applications up to 12.4 GHz and are mechanically compatible for panel mount bulkhead installations.

Amphenol RF 132333 is the primary specification part with gold housing and gold body finish. It is optimized for Belden cable groups 9913, 9914, and LMR-400.

Cinch 142-0303-411 provides an equivalent substitute with gold housing and gold body finish. It supports RG-series cable groups 161, 174, 188, and 316, and offers contact termination flexibility with crimp or solder options. This part includes a voltage rating of 250 V.

Cinch 142-0303-416 provides an equivalent substitute with silver housing and nickel body finish. It supports the same RG-series cable groups as 142-0303-411 and includes the same voltage rating of 250 V and termination flexibility.

Selection between these parts depends on cable compatibility requirements, housing finish specifications, and available inventory. All three parts maintain identical RF performance and mechanical mounting characteristics.

Frequently Asked Questions (FAQ)

Q: Can Cinch 142-0303-411 or 142-0303-416 be used as direct replacements for Amphenol RF 132333?

A: Yes. Both Cinch parts meet all critical electrical and mechanical specifications: SMA jack female socket, 50 ohms impedance, 12.4 GHz maximum frequency, panel mount bulkhead configuration, crimp shield termination, PTFE dielectric, and identical operating temperature and mating cycle ratings. The parts are functionally equivalent for RF applications.

Q: What are the differences between the two Cinch substitute parts?

A: Cinch 142-0303-411 features gold housing and gold body finish. Cinch 142-0303-416 features silver housing and nickel body finish. Both parts are electrically identical and support the same cable groups and termination options. Selection depends on finish specification requirements.

Q: Are there cable compatibility differences between the main part and substitutes?

A: The Amphenol RF 132333 is optimized for Belden 9913, 9914, and LMR-400 cables. The Cinch substitutes support RG-series cables 161, 174, 188, and 316. Cable group compatibility should be verified against your specific application requirements, though all parts maintain 50 ohm impedance and crimp termination capability.

Q: Do the substitute parts support solder termination?

A: The Cinch parts 142-0303-411 and 142-0303-416 support both crimp and solder contact termination. The Amphenol RF 132333 specifies crimp termination only. If solder termination is required, the Cinch substitutes provide this additional capability.

Q: Are all three parts RoHS and REACH compliant?

A: Yes. All three parts are ROHS3 compliant and REACH affected. They share identical regulatory status and are suitable for applications requiring these certifications.

Q: What is the packaging difference between the main part and substitutes?

A: The Amphenol RF 132333 is supplied in bag packaging. Both Cinch substitutes are supplied in bulk packaging. Packaging format does not affect connector performance or compatibility.

Q: Are the operating temperature ranges identical?

A: Yes. All three parts operate across -65°C to 165°C and support 500 mating cycles, ensuring equivalent reliability across thermal extremes.
