Key Parameters

Substitute Part Grouping Explanation

The identified substitute part RNS3R0E from Ohmite is classified as a functionally equivalent alternative based on the following criteria:

Substitution Logic:

• Both components are linear potentiometers designed for rotational adjustment
• Both are classified as wirewound resistive elements
• Both feature panel mount configuration with solder lug termination
• Both are rated for high-power applications (300W)
• Both maintain compatibility with standard potentiometer mounting interfaces

Key Parameters Determining Substitution:

• Resistance value: 3 Ohms
• Taper type: Linear
• Resistive material: Wirewound
• Termination style: Solder Lug
• Mounting type: Panel Mount
• Number of gangs: 1
• Number of turns: 1

Engineering Selection Recommendations

The RNS3R0E potentiometer from Ohmite is an active product with current manufacturing status and ROHS3 compliance certification. This substitute part addresses the obsolescence of the RT230AS3R30KB by providing equivalent functional performance with documented electrical and mechanical specifications. The active product status ensures availability for procurement and ongoing supply chain support.

Selection of the RNS3R0E is appropriate for applications requiring a 3-ohm, 300-watt wirewound linear potentiometer with panel mount configuration and solder lug termination. The specified rotation angle of 320° and actuator dimensions provide mechanical compatibility with standard potentiometer mounting interfaces.

Frequently Asked Questions (FAQ)

Q: Why is the RT230AS3R30KB listed as obsolete? A: The RT230AS3R30KB has been discontinued by Vishay Sfernice and is no longer in active production. The RNS3R0E from Ohmite provides equivalent functionality with current manufacturing support.

Q: What are the critical parameters for substitution compatibility? A: Substitution compatibility is determined by resistance value (3 Ohms), power rating (300W), resistive material (wirewound), taper type (linear), termination style (solder lug), and mounting configuration (panel mount). These parameters ensure electrical and mechanical interchangeability.

Q: Is the RNS3R0E mechanically compatible with the original mounting interface? A: The RNS3R0E features panel mount configuration with a round body diameter of 6.000 inches (152.40mm) and solder lug termination, which are standard specifications for potentiometer mounting interfaces. Verification of specific mounting hole patterns and clearances in the application is required.

Q: What compliance certifications does the substitute part carry? A: The RNS3R0E is ROHS3 compliant and classified under ECCN EAR99. These certifications indicate compliance with current environmental and export control standards.

Q: What is the packaging format for the RNS3R0E? A: The RNS3R0E is supplied in bulk packaging format.
