Substitute Part Grouping Explanation

Substitution of coaxial RF connectors is determined by strict equivalence across electrical and mechanical parameters. The Amphenol RF 132131 and Cinch Connectivity Solutions 142-0203-101 are classified as direct substitutes based on the following criteria:

Electrical Equivalence:

• Identical connector style (SMA)
• Identical connector type (Plug, Male Pin)
• Identical impedance specification (50 Ohms)
• Identical maximum frequency rating (12.4 GHz)
• Identical contact termination method (Solder)
• Identical shield termination method (Clamp)

Mechanical Equivalence:

• Identical mounting type (Free Hanging/In-Line, Right Angle)
• Identical fastening type (Threaded)
• Identical operating temperature range (-65°C ~ 165°C)
• Identical mating cycle rating (500 cycles)
• Identical number of ports (1)

Material and Finish Equivalence:

• Identical body material (Brass)
• Identical body finish (Gold)
• Identical center contact material (Brass)
• Identical center contact plating (Gold)
• Identical dielectric material (Polytetrafluoroethylene/PTFE)

Compliance Equivalence:

• Identical RoHS3 compliance status
• Identical REACH compliance status
• Identical Moisture Sensitivity Level (MSL 1)
• Identical ECCN classification (EAR99)
• Identical HTSUS code (8536.69.4010)

Cable Compatibility: Both parts support RG-174 and RG-188 cable groups, with the substitute supporting additional RG-161 compatibility.

Engineering Selection Recommendations

Primary Selection: Amphenol RF 132131

The Amphenol RF 132131 is the primary component specification. This part maintains Active product status with full RoHS3 and REACH compliance. The 375 V voltage rating provides operational margin for applications requiring higher voltage tolerance. Current inventory of 818 pieces supports immediate deployment.

Substitute Selection: Cinch Connectivity Solutions 142-0203-101

The Cinch 142-0203-101 serves as a direct electrical and mechanical substitute for the Amphenol RF 132131. Both components meet identical RF performance specifications, operating temperature ranges, and compliance requirements. The substitute maintains RoHS3 and REACH compliance status with equivalent MSL classification.

Voltage Rating Consideration:

The Cinch substitute specifies a 250 V voltage rating compared to the Amphenol primary part's 375 V rating. Applications operating at voltages between 250 V and 375 V require confirmation that the substitute meets specific circuit requirements. For applications operating below 250 V, the substitute presents no operational limitation.

Packaging and Inclusion Differences:

The Cinch 142-0203-101 is supplied in bulk packaging and includes four components per connector unit: connector body, clamp cone, clamp nut, and end cap. The Amphenol 132131 packaging specification is not detailed in the provided parameters. Assembly and integration workflows should account for this inclusion difference.

Cable Compatibility:

Both parts support RG-174 and RG-188 cable groups. The Cinch substitute additionally supports RG-161 cable compatibility, providing expanded cable selection options.

Frequently Asked Questions (FAQ)

Q: Can the Cinch 142-0203-101 directly replace the Amphenol RF 132131 in all applications?

A: The Cinch 142-0203-101 is electrically and mechanically equivalent to the Amphenol RF 132131 across all RF performance parameters, operating temperature range, and compliance certifications. The primary consideration is the voltage rating difference: the Cinch part is rated for 250 V versus the Amphenol part's 375 V. Applications operating at voltages below 250 V experience no limitation. Applications requiring voltage operation between 250 V and 375 V require circuit-level verification.

Q: What are the key electrical parameters that define substitution eligibility?

A: SMA connector plug substitution is determined by equivalence in connector style, connector type (male pin), impedance (50 Ohms), contact termination method (solder), shield termination method (clamp), maximum frequency rating (12.4 GHz), and number of ports (1). Both the primary and substitute parts meet these specifications identically.

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

A: Both the Amphenol RF 132131 and Cinch 142-0203-101 maintain identical compliance status: RoHS3 compliant, REACH affected, EAR99 ECCN classification, and MSL 1 (Unlimited) moisture sensitivity level. No regulatory or compliance barriers exist for substitution.

Q: What is the significance of the included components in the Cinch part?

A: The Cinch 142-0203-101 includes clamp cone, clamp nut, and end cap components as part of the connector assembly. These components support the clamp-based shield termination method. Assembly procedures should account for these inclusions when integrating the substitute part into production workflows.

Q: Do both parts support the same cable types?

A: Both parts support RG-174 and RG-188 cable groups. The Cinch substitute additionally supports RG-161 cable compatibility. The Amphenol primary part supports RG-316 and LMR-100 cable groups. Cable selection should be verified against specific application requirements.

Q: What is the mating cycle rating for these connectors?

A: Both the Amphenol RF 132131 and Cinch 142-0203-101 are rated for 500 mating cycles, indicating equivalent mechanical durability and connector life expectancy.

Q: Are there temperature operating range differences?

A: Both parts operate identically across the temperature range of -65°C to 165°C. No thermal performance differentiation exists between the primary and substitute parts.
