Amphenol RF 112120 BNC Connector Plug Equivalent & Substitute Parts

Part Overview

The Amphenol RF 112120 is a BNC connector plug designed for 50-ohm coaxial cable applications. This male pin connector features crimp termination for both center contact and shield, with a bayonet lock fastening mechanism. The part is classified as Not For New Designs, indicating it has been superseded in the manufacturer's product line. Organizations requiring this connector type must evaluate active alternative components that maintain electrical and mechanical compatibility with existing cable assemblies and system specifications.

Substitute Part Grouping Explanation

Substitute parts for the Amphenol RF 112120 are classified into two categories based on electrical and mechanical parameter alignment:

Direct Equivalent (Category 1): Parts that maintain identical specifications across all critical parameters including connector style, impedance, termination method, mounting configuration, and frequency rating. These substitutes provide drop-in replacement capability without design modification.

Compatible Alternative (Category 2): Parts that share the same connector style, impedance, and mounting type but differ in one or more secondary parameters such as contact termination method, frequency rating, or supported cable groups. These alternatives require verification of system compatibility before implementation.

The following parameters determine substitution eligibility:

• Connector Style (BNC)
• Connector Type (Plug, Male Pin)
• Impedance (50 Ohms)
• Mounting Type (Free Hanging In-Line)
• Fastening Type (Bayonet Lock)
• Voltage Rating (500 V minimum)
• Mating Cycles (500 minimum)

Engineering Selection Recommendations

Amphenol RF 112116 is the primary substitute for Amphenol RF 112120. Both connectors are manufactured by Amphenol RF and maintain identical electrical and mechanical specifications across all critical parameters. The 112116 is classified as Active product status, ensuring continued availability and manufacturing support. This connector provides direct compatibility with the same cable groups (RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, 9907) and maintains equivalent performance characteristics including 4 GHz frequency rating, 0.2 dB insertion loss, and crimp termination for both center contact and shield. Current inventory of 3,792 pieces supports immediate procurement requirements.

TE Connectivity 2-5330358-2 is a compatible alternative that shares the same BNC connector style, 50-ohm impedance, bayonet lock fastening, and free-hanging mounting configuration. However, this connector differs in three significant parameters: contact termination uses push-on rather than crimp, supported cable groups are limited to RG-142, 142A, and 142B, and maximum frequency is 2.5 GHz rather than 4 GHz. The dielectric material differs (PTFE versus POM Acetal) and body finish is silver rather than nickel. This alternative is suitable only for applications where the cable group compatibility and lower frequency rating align with system requirements. Both substitute options maintain ROHS3 compliance and REACH affected status consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Can Amphenol RF 112116 be used as a direct replacement for Amphenol RF 112120?

A: Yes. The 112116 maintains identical specifications for connector style, impedance, termination methods, mounting type, frequency rating, voltage rating, and mating cycles. Both connectors support the same cable groups and deliver equivalent electrical performance. The 112116 is the recommended substitute due to its active product status.

Q: What is the primary difference between Amphenol RF 112120 and TE Connectivity 2-5330358-2?

A: The primary differences are contact termination method (crimp versus push-on), supported cable groups (RG-58 series versus RG-142 series), and maximum frequency (4 GHz versus 2.5 GHz). The TE Connectivity connector is not a direct replacement and requires system compatibility assessment before use.

Q: Why is Amphenol RF 112120 marked as Not For New Designs?

A: This designation indicates the part has been superseded in the manufacturer's product line. Amphenol RF 112116 is the active equivalent and should be specified for new designs and procurement.

Q: Are the cable groups interchangeable between Amphenol RF 112116 and TE Connectivity 2-5330358-2?

A: No. Amphenol RF 112116 supports RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, and 9907 cable groups. TE Connectivity 2-5330358-2 supports only RG-142, 142A, and 142B. Cable group compatibility must be confirmed before substitution.

Q: What is the significance of the dielectric material difference between these connectors?

A: Amphenol RF connectors use Polyoxymethylene (POM) Acetal dielectric, while TE Connectivity uses Polytetrafluoroethylene (PTFE). Both materials are suitable for 50-ohm RF applications, but PTFE offers superior high-frequency performance and temperature stability. Material selection depends on specific application requirements.

Q: Do all three connectors meet the same compliance standards?

A: Yes. All three connectors are ROHS3 compliant and REACH affected. They share identical ECCN (EAR99) and HTSUS (8536.69.4010) classifications.

Q: What is the insertion loss specification for TE Connectivity 2-5330358-2?

A: Insertion loss is not specified in the available technical data for TE Connectivity 2-5330358-2. Amphenol RF 112120 and 112116 both specify 0.2 dB insertion loss.

Q: Are there packaging differences between these connectors?

A: Amphenol RF 112120 and 112116 are packaged in bags. TE Connectivity 2-5330358-2 packaging information is not specified in the available data.
