Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Amphenol RF 132241 are qualified based on the following criteria:

Electrical Compatibility:

• Connector style: SMA (standardized interface)
• Impedance: 50 ohms (RF transmission standard)
• Frequency rating: 12.4 GHz maximum
• Operating temperature: -65°C ~ 165°C

Mechanical Compatibility:

• Connector type: Jack, female socket
• Mounting configuration: Panel mount with bulkhead front side nut
• Fastening type: Threaded
• Center contact material: Beryllium copper
• Dielectric material: PTFE

Termination Flexibility: The main part specifies solder termination. Substitute parts may offer crimp or solder termination options, provided the connector maintains electrical and mechanical interface compatibility with standard SMA mating plugs.

Compliance:

• RoHS3 compliant
• REACH affected
• ECCN: EAR99
• HTSUS: 8536.69.4010

The identified substitutes (Cinch Connectivity Solutions 142-0303-411 and 142-0303-416) meet all core electrical and mechanical parameters while offering alternative termination methods and housing finishes.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Amphenol RF 132241): Use when solder termination is the specified assembly method and gold housing finish is required for corrosion resistance in high-reliability applications. Active product status ensures ongoing manufacturer support and supply chain stability.

Substitute Selection (Cinch 142-0303-411): Use when crimp termination capability is preferred or when assembly processes require flexible termination options. Gold housing finish maintains corrosion resistance equivalent to the primary part. ROHS3 compliance and REACH affected status match the primary part.

Substitute Selection (Cinch 142-0303-416): Use when nickel housing finish is acceptable for the application and crimp termination capability is required. Nickel finish provides alternative surface treatment while maintaining electrical performance. ROHS3 compliance and REACH affected status match the primary part. Housing color difference (silver vs. gold) reflects the nickel finish specification.

All three parts maintain identical electrical performance at 50 ohms impedance, 12.4 GHz maximum frequency, and -65°C ~ 165°C operating temperature range. Compliance certifications (ROHS3, REACH, EAR99, HTSUS) are equivalent across all options.

Frequently Asked Questions (FAQ)

Q: Can Cinch 142-0303-411 and 142-0303-416 be used interchangeably with Amphenol RF 132241?

A: Yes, within the constraints of termination method and housing finish. All three parts share identical SMA connector interface, 50 ohm impedance, 12.4 GHz frequency rating, and panel mount bulkhead configuration. The Cinch parts offer crimp or solder termination flexibility, while the Amphenol part specifies solder only. Housing finish differs (gold vs. nickel), which may affect corrosion resistance in specific environmental conditions.

Q: What is the difference between the two Cinch substitute parts?

A: Cinch 142-0303-411 features gold body finish, while Cinch 142-0303-416 features nickel body finish. Both offer identical electrical specifications, termination flexibility (crimp or solder), and mechanical compatibility. Selection depends on environmental requirements and finish specifications for the application.

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

A: The Amphenol RF 132241 is specified for RG-8X, Belden 9258, and LMR-240 cable groups. The Cinch substitutes are specified for RG-161, 174, 188, and 316 cable groups. Cable compatibility must be verified based on the specific application requirements and connector termination method selected.

Q: Do all parts meet the same compliance requirements?

A: Yes. All three parts are ROHS3 compliant, REACH affected, classified as EAR99, and share the same HTSUS code (8536.69.4010). Moisture sensitivity level is 1 (Unlimited) for all parts, indicating no special storage or handling requirements.

Q: What is the significance of the 500 mating cycle rating?

A: The 500 mating cycle specification indicates the connector is rated for 500 connection and disconnection cycles under normal operating conditions. This parameter is identical across all three parts and applies to the mechanical interface between the SMA jack and mating plug.
