Amphenol RF 112124 BNC Connector Plug Equivalent & Substitute Parts

Part Overview

The Amphenol RF 112124 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 The part is classified as "Not For New Designs," indicating it has been superseded in the manufacturer's product line. Finding equivalent or substitute parts is necessary for applications requiring active product status, improved availability, or alternative termination methods while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Amphenol RF 112124 are grouped based on strict electrical and mechanical compatibility criteria. The primary substitution logic follows these parameters:

Direct Substitutes (Identical Electrical and Mechanical Specifications): Parts must maintain 50-ohm impedance, BNC connector style, male pin configuration, bayonet lock fastening, and free-hanging mounting type. Direct substitutes retain the same frequency maximum (4 GHz), voltage rating (500 V), and mating cycle rating (500).

Similar Substitutes (Compatible with Parameter Variations): Parts may differ in contact termination method (crimp versus push-on), cable group compatibility, dielectric material, body finish, frequency maximum, or operating temperature range, provided the core electrical impedance, connector style, and fastening mechanism remain unchanged. These parts are suitable for applications where the specific termination method or frequency range does not create a functional constraint.

The following parameters determine substitution eligibility:

• Connector style (BNC)
• Connector type (Plug, Male Pin)
• Impedance (50 Ohms)
• Fastening type (Bayonet Lock)
• Mounting type (Free Hanging/In-Line)
• Voltage rating (500 V minimum)
• Mating cycles (500 minimum)

Parameter Comparison

Engineering Selection Recommendations

Amphenol RF 112128 (Direct Substitute): The Amphenol RF 112128 is the primary equivalent for the 112124. Both parts share identical electrical specifications (50-ohm impedance, 4 GHz maximum frequency, 500 V rating, 0.2 dB insertion loss) and mechanical configuration (BNC plug, male pin, crimp termination, bayonet lock, free-hanging mount). The 112128 holds Active product status, whereas the 112124 is classified as Not For New Designs. The 112128 is suitable for direct replacement in all applications where the 112124 was previously specified. Both parts are ROHS3 compliant and REACH affected.

TE Connectivity 2-5330358-2 (Similar Substitute): The TE Connectivity 2-5330358-2 is a compatible alternative with the following considerations: it maintains 50-ohm impedance, BNC connector style, male pin configuration, bayonet lock fastening, and free-hanging mounting. However, it differs in three parameters: (1) contact termination is push-on rather than crimp, (2) maximum frequency is 2.5 GHz rather than 4 GHz, and (3) dielectric material is PTFE rather than POM acetal. The 2-5330358-2 is suitable for applications operating at frequencies up to 2.5 GHz where push-on termination is acceptable. This part is Active and ROHS3 compliant. The specified operating temperature range (-55°C ~ 85°C) provides additional environmental specification compared to the Amphenol parts.

Selection between these substitutes depends on application frequency requirements and termination method compatibility. For applications requiring 4 GHz operation or crimp termination, the Amphenol RF 112128 is the appropriate choice. For applications with frequency requirements up to 2.5 GHz and where push-on termination is acceptable, the TE Connectivity 2-5330358-2 provides an alternative from a different manufacturer.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RF 112128 be used as a direct replacement for the 112124?

A: Yes. The 112128 is electrically and mechanically identical to the 112124. Both parts have 50-ohm impedance, 4 GHz maximum frequency, 500 V voltage rating, 0.2 dB insertion loss, crimp termination for both center contact and shield, bayonet lock fastening, and free-hanging mounting. The primary difference is product status: the 112128 is Active while the 112124 is Not For New Designs.

Q: What is the key difference between the Amphenol RF 112128 and the TE Connectivity 2-5330358-2?

A: The primary differences are contact termination method, maximum frequency, and dielectric material. The 112128 uses crimp termination and operates to 4 GHz with POM acetal dielectric. The 2-5330358-2 uses push-on termination and operates to 2.5 GHz with PTFE dielectric. Both maintain 50-ohm impedance and bayonet lock fastening.

Q: Is the TE Connectivity 2-5330358-2 suitable for all applications using the 112124?

A: The 2-5330358-2 is suitable for applications operating at frequencies up to 2.5 GHz. If your application requires operation above 2.5 GHz, the Amphenol RF 112128 is required. Additionally, if your assembly process requires crimp termination, the 2-5330358-2 push-on termination may not be compatible with existing tooling or procedures.

Q: Are all three parts RoHS3 compliant?

A: Yes. The Amphenol RF 112124, Amphenol RF 112128, and TE Connectivity 2-5330358-2 are all ROHS3 compliant and REACH affected.

Q: What cable groups are compatible with each part?

A: The Amphenol RF 112124 and 112128 are compatible with RG-58 Plenum, 122, Belden 88240, and 89907 cable groups. The TE Connectivity 2-5330358-2 is compatible with RG-142, 142A, and 142B cable groups. Cable group compatibility must be verified for your specific application.

Q: What is the difference in body finish between these parts?

A: The Amphenol RF 112124 and 112128 have nickel body finish. The TE Connectivity 2-5330358-2 has silver body finish. All three parts have gold-plated center contacts. Body finish does not affect electrical performance but may influence corrosion resistance in specific environmental conditions.

Q: Do all parts have the same mating cycle rating?

A: Yes. All three parts have a mating cycle rating of 500 cycles.

Q: What is the operating temperature range for each part?

A: The Amphenol RF 112124 and 112128 do not specify an operating temperature range in the provided data. The TE Connectivity 2-5330358-2 specifies -55°C to 85°C operating temperature range.

Q: Are there any packaging differences between these parts?

A: The Amphenol RF 112124 and 112128 are packaged in bags. The TE Connectivity 2-5330358-2 packaging is not specified in the provided data.
