Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Amphenol RF 132250 is determined by strict adherence to the following core electrical and mechanical parameters:

Critical Matching Parameters:

• Connector Style: SMA (industry-standard RF interface)
• Connector Type: Plug, Male Pin (mating interface requirement)
• Impedance: 50 Ohms (signal integrity specification)
• Mounting Type: Free Hanging (In-Line), Right Angle (physical orientation)
• Contact Termination: Solder (assembly method)
• Shield Termination: Solder (assembly method)
• Frequency - Max: 18 GHz (bandwidth capability)
• Operating Temperature: -65°C to 165°C (environmental rating)
• Mating Cycles: 500 (durability specification)
• Fastening Type: Threaded (connection mechanism)

Variable Parameters (Cable Group Specific): The identified substitute parts differ in cable group compatibility. The main part accommodates 0.047" semi-rigid cable, while substitutes support RG-405 (.086" semi-rigid) and RG-402 (.141" semi-rigid) configurations. These variations allow connector selection based on specific cable assembly requirements while maintaining full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts—Amphenol RF 132250, Cinch 142-0693-101, and Cinch 142-0694-101—are active production components with full ROHS3 compliance and REACH compliance status. Selection between these parts is determined by cable group compatibility requirements:

Amphenol RF 132250 is specified for 0.047" semi-rigid cable assemblies and is the primary reference part with 747 units in current inventory.

Cinch 142-0693-101 accommodates RG-405 (.086" semi-rigid) cable and provides 1230 units in inventory with a voltage rating of 335 V.

Cinch 142-0694-101 accommodates RG-402 (.141" semi-rigid) cable and provides 807 units in inventory with a voltage rating of 500 V.

All substitute parts maintain identical electrical performance specifications (50-ohm impedance, 18 GHz maximum frequency, -65°C to 165°C operating range, 500 mating cycles) and mechanical interface compatibility (SMA male plug, right-angle solder termination, threaded fastening). Selection should be based on the specific cable diameter requirement of the target application.

Frequently Asked Questions (FAQ)

Q: Can Cinch 142-0693-101 or 142-0694-101 be used as direct replacements for Amphenol RF 132250?

A: Yes, both Cinch parts are electrically and mechanically compatible substitutes. The primary difference is cable group compatibility. The Amphenol 132250 is designed for 0.047" semi-rigid cable, while Cinch 142-0693-101 supports RG-405 (.086" semi-rigid) and Cinch 142-0694-101 supports RG-402 (.141" semi-rigid). Selection depends on the cable diameter specified in your assembly.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is based on matching: connector style (SMA), connector type (plug, male pin), impedance (50 ohms), mounting type (free hanging, right angle), termination method (solder), frequency rating (18 GHz), operating temperature range (-65°C to 165°C), mating cycles (500), and fastening type (threaded). Cable group is a variable parameter that determines which substitute is appropriate for a specific application.

Q: Are there compliance or certification differences between these parts?

A: No. All three parts carry identical compliance certifications: ROHS3 compliant, REACH affected, EAR99 export classification, and HTSUS code 8536.69.4010. All are rated MSL 1 (unlimited moisture sensitivity level).

Q: What is the difference in center contact material between the Amphenol and Cinch parts?

A: The Amphenol RF 132250 uses beryllium copper for the center contact, while both Cinch substitutes use brass. Both materials are gold-plated and provide equivalent electrical performance within the specified frequency and impedance parameters.

Q: How do voltage ratings differ between the Cinch substitutes?

A: Cinch 142-0693-101 is rated for 335 V, while Cinch 142-0694-101 is rated for 500 V. The higher voltage rating of the 142-0694-101 corresponds to its larger cable diameter (RG-402 .141" versus RG-405 .086"). Select based on your application's voltage requirements and cable specification.

Q: What packaging differences exist?

A: The Amphenol RF 132250 is supplied in bag packaging, while both Cinch substitutes are supplied in bulk packaging. This affects handling and inventory management but does not impact electrical or mechanical performance.

Q: Are all parts rated for the same frequency range?

A: Yes. All three parts are rated to 18 GHz maximum frequency, ensuring equivalent RF performance across the specified bandwidth.
