VB20-2050 Equivalent & Substitute Parts

Part Overview

The VB20-2050 is a BNC connector plug manufactured by Cinch Connectivity Solutions, designed for coaxial RF applications requiring 50 Ohm impedance. This right-angle crimp connector is configured as a male pin, free-hanging (in-line) component suitable for RG-142, RG-223, and RG-400 cable groups. The part is currently active in production with 796 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the connector interface, enabling interchangeable component selection for procurement flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VB20-2050 is determined by strict equivalence across the following critical parameters:

• Connector style (BNC) and type (Plug, Male Pin)
• Electrical impedance (50 Ohms)
• Mounting configuration (Free Hanging, Right Angle)
• Termination method (Crimp for both contact and shield)
• Compatible cable groups (RG-142, RG-223, RG-400)
• Fastening mechanism (Bayonet Lock)
• Maximum frequency rating (4 GHz minimum)
• Mating cycle rating (500 minimum)

The substitute part R141183000 (Radiall USA, Inc.) meets all these criteria, maintaining full electrical and mechanical compatibility with the VB20-2050 within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

The R141183000 is manufactured by Radiall USA, Inc. with 859 units in stock and carries ROHS3 compliance and REACH affected status certifications. Selection between these parts should be based on procurement requirements, supply availability, and applicable regulatory compliance mandates for the end application. Both connectors maintain identical performance parameters within the specified 50 Ohm, 4 GHz operating envelope.

Frequently Asked Questions (FAQ)

Q: Can R141183000 be used as a direct replacement for VB20-2050?

A: Yes. Both connectors share identical BNC plug male pin configuration, 50 Ohm impedance, right-angle crimp termination, and compatibility with RG-142, RG-223, and RG-400 cable groups. Electrical and mechanical interface parameters are equivalent.

Q: What are the key compatibility criteria for BNC connector substitution?

A: Connector style, type (plug vs. jack), impedance rating, mounting orientation, termination method, cable group compatibility, and frequency rating must all match. For the VB20-2050, these parameters are: BNC plug, 50 Ohms, right-angle crimp, RG-142/223/400 compatible, and 4 GHz maximum frequency.

Q: Are there differences in operating temperature ranges between these parts?

A: Yes. The VB20-2050 operates from -55°C to 85°C, while the R141183000 operates from -65°C to 165°C. The R141183000 provides an extended temperature range. Application requirements determine whether this difference is relevant to component selection.

Q: What packaging is provided with each connector?

A: Both parts are supplied in bulk packaging, each including 3 pieces: 1 connector, 1 contact, and 1 ferrule.

Q: Are there compliance differences between these substitutes?

A: The R141183000 carries ROHS3 compliance and REACH affected status. The VB20-2050 compliance information is not specified in the provided data. Regulatory requirements for the end application determine whether these certifications are necessary.
