Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Amphenol RF 112135 is determined by the following core parameters that must remain constant across all equivalent parts:

Mandatory Matching Parameters:

• Connector Style: BNC
• Connector Type: Plug, Male Pin
• Impedance: 75 Ohms
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Bayonet Lock
• Voltage Rating: 500 V
• Number of Ports: 1

Parameters Allowing Variation:

• Contact Termination: Crimp or Solder (both acceptable for signal integrity)
• Frequency Maximum: 2 GHz or higher (backward compatible)
• Operating Temperature Range: May extend beyond -40°C ~ 85°C
• Dielectric Material: Polyoxymethylene (POM) Acetal or Polytetrafluoroethylene (PTFE)
• Cable Group Compatibility: Varies by specific connector variant
• Product Status: Active status preferred for new applications

The substitute parts listed below maintain all mandatory parameters while offering improvements in frequency performance, temperature operating range, or product lifecycle status.

Engineering Selection Recommendations

For Direct Crimp Termination Replacement (Same Contact Method):

The Cinch Connectivity Solutions Trompeter UPL220 series connectors (UPL220-009, UPL220-020, UPL220-025, UPL220-026) provide direct functional equivalence to the Amphenol RF 112135 with crimp contact termination. All four variants maintain identical core electrical specifications (75 ohms, 500 V, bayonet lock) while offering superior frequency performance (4 GHz versus 2 GHz) and extended operating temperature range (-65°C ~ 165°C versus -40°C ~ 85°C). These parts carry active product status and ROHS3 compliance. Selection among UPL220-009, UPL220-020, UPL220-025, and UPL220-026 is determined by cable group compatibility requirements specific to the application.

For Alternative Termination Method (Solder Contact):

The Amphenol RF 031-71013-RFX provides equivalent functionality with solder contact termination instead of crimp. This part maintains the same 75 ohm impedance, 500 V rating, and bayonet lock fastening. It offers improved frequency performance (3 GHz versus 2 GHz) and carries active product status with ROHS3 compliance. The solder termination method requires different assembly procedures compared to the crimp method of the original part.

Compliance and Lifecycle Considerations:

All substitute parts listed carry active product status, making them suitable for new design implementations. The Amphenol RF 112135 is designated "Not For New Designs," indicating it should be replaced in new applications. All substitute parts maintain ROHS3 compliance and REACH affected status consistent with the original part, ensuring regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can the Cinch UPL220 series connectors directly replace the Amphenol RF 112135 in existing assemblies?

A: Yes, the UPL220 series maintains all mandatory electrical and mechanical parameters: 75 ohm impedance, 500 V rating, bayonet lock fastening, crimp termination, and free hanging in-line mounting. Physical compatibility is ensured through identical connector style and type. Cable group compatibility must be verified for the specific variant selected.

Q: What is the difference between the Amphenol RF 031-71013-RFX and the Amphenol RF 112135?

A: Both are Amphenol RF BNC connectors with 75 ohm impedance and 500 V rating. The primary difference is contact termination: the 112135 uses crimp termination while the 031-71013-RFX uses solder termination. The 031-71013-RFX offers higher frequency performance (3 GHz versus 2 GHz) and active product status. Assembly methods differ based on termination type.

Q: Why do the Cinch UPL220 variants have different part numbers if they are all equivalent?

A: The UPL220-009, UPL220-020, UPL220-025, and UPL220-026 variants differ in cable group compatibility. Each variant is optimized for specific coaxial cable types: UPL220-009 for Belden 8218 and Essex cables, UPL220-020 for Belden 9248, and UPL220-025 and UPL220-026 for 734A and 735A cable groups respectively. Electrical and mechanical specifications remain identical across all variants.

Q: Are there temperature performance differences between the Amphenol RF 112135 and substitute parts?

A: Yes. The Amphenol RF 112135 operates from -40°C to 85°C. The Amphenol RF 031-71013-RFX operates from -40°C to 80°C. All Cinch UPL220 variants operate from -65°C to 165°C, providing significantly extended temperature range capability. Application temperature requirements determine whether the extended range is necessary.

Q: What is the significance of the dielectric material difference between the original part and Cinch substitutes?

A: The Amphenol RF 112135 uses Polyoxymethylene (POM) Acetal dielectric, while the Cinch UPL220 series uses Polytetrafluoroethylene (PTFE) dielectric. Both materials are suitable for 75 ohm RF applications. PTFE offers superior high-temperature performance and lower dielectric loss, contributing to the extended operating temperature range and improved frequency performance of the UPL220 series.

Q: Can the Amphenol RF 112135 be used in new product designs?

A: No. The Amphenol RF 112135 carries "Not For New Designs" product status, indicating it has been superseded. New designs should utilize active status alternatives such as the Amphenol RF 031-71013-RFX or Cinch UPL220 series connectors to ensure long-term component availability and manufacturer support.

Q: What packaging differences exist between the main part and substitutes?

A: The Amphenol RF 112135 is supplied in bag packaging, while the Amphenol RF 031-71013-RFX and all Cinch UPL220 variants are supplied in bulk packaging. Packaging format does not affect electrical or mechanical compatibility; it reflects distribution and inventory management differences.

Q: How do insertion loss specifications compare across these connectors?

A: The Amphenol RF 112135 does not specify insertion loss. The Amphenol RF 031-71013-RFX specifies 0.2 dB insertion loss. The Cinch UPL220 series does not provide insertion loss specifications in the available data. For applications requiring specific insertion loss performance, the 031-71013-RFX with documented 0.2 dB specification is the appropriate selection.
