Substitute Part Grouping Explanation

The RNS25RE from Ohmite serves as a manufacturer-recommended substitute for the RT230AS33R0KB. Substitution eligibility is determined by the following criteria present in both components:

• Product category: Linear potentiometer
• Adjustment type: User-defined rotational control
• Taper characteristic: Linear response
• Termination method: Solder lug connection
• Mounting configuration: Panel mount installation
• Resistive element: Wirewound construction
• Actuator type: Flatted design
• Moisture sensitivity classification: Not applicable to both components

The RNS25RE maintains functional equivalence through matching adjustment methodology, linear taper response, and panel-mount configuration suitable for applications requiring the RT230AS33R0KB.

Engineering Selection Recommendations

The RNS25RE is designated as the manufacturer-recommended substitute for the obsolete RT230AS33R0KB. Selection of this alternative is supported by the following factors:

• The RT230AS33R0KB is classified as obsolete, eliminating it as a viable option for procurement
• The RNS25RE maintains active product status with confirmed inventory availability
• The RNS25RE achieves ROHS3 compliance, meeting current regulatory requirements
• Both components share compatible functional characteristics: linear potentiometer classification, user-defined adjustment capability, and panel-mount configuration
• The RNS25RE provides specified electrical parameters (25 Ohm resistance, 300W power rating) and mechanical dimensions suitable for direct substitution in applications previously utilizing the RT230AS33R0KB

Frequently Asked Questions (FAQ)

Q: Why is the RT230AS33R0KB no longer available? A: The RT230AS33R0KB is classified as obsolete and has been discontinued by Vishay Sfernice. Obsolete status indicates the manufacturer no longer produces or supports this component.

Q: What makes the RNS25RE a suitable substitute? A: The RNS25RE is the manufacturer-recommended equivalent.
