Substitute Part Grouping Explanation

Substitution of the RT230AS1001KB is based on the following criteria derived from available technical specifications:

• Functional Type: Linear potentiometer with rotational adjustment capability
• Resistance Value: 1k Ohm nominal (inferred from substitute part designation)
• Power Rating: High-power wirewound construction
• Mounting Configuration: Panel mount with solder lug termination
• Actuator Specifications: Flatted actuator type with defined length and diameter
• Resistive Material: Wirewound construction for precision and power handling
• Rotation Angle: Multi-turn or defined rotation range
• Termination: Solder lug connection style

The substitute part RRS1K0E from Ohmite meets these functional requirements with active product status and current manufacturing availability.

Engineering Selection Recommendations

The RRS1K0E from Ohmite is the designated manufacturer-recommended substitute for the obsolete RT230AS1001KB. Selection of this alternative is justified by the following factors:

• Product Status: The RRS1K0E maintains active manufacturing status, ensuring long-term availability and supply chain continuity
• Compliance: The RRS1K0E is ROHS3 compliant, meeting current environmental and regulatory requirements
• Functional Equivalence: Both components are single-gang linear potentiometers with wirewound resistive elements and solder lug termination
• Power Handling: The RRS1K0E provides 500W power rating, suitable for high-power applications
• Mechanical Compatibility: Panel mount configuration with flatted actuator design maintains interface compatibility with existing mechanical assemblies

Frequently Asked Questions (FAQ)

Q: Why is the RT230AS1001KB no longer available? A: The RT230AS1001KB is classified as obsolete and is no longer in active production by Vishay Sfernice. Existing inventory of 717 pieces remains available through authorized distributors, but new production is not available.

Q: What makes the RRS1K0E a suitable substitute? A: The RRS1K0E is the manufacturer-recommended equivalent, offering identical functional characteristics as a single-gang linear potentiometer with wirewound construction, solder lug termination, and panel mount configuration. Both components share the same resistance value and taper characteristics.

Q: Are there mechanical compatibility concerns when substituting? A: The RRS1K0E maintains panel mount configuration with a flatted actuator design, ensuring mechanical compatibility with assemblies designed for the RT230AS1001KB. Physical dimensions and mounting interfaces are equivalent.

Q: What is the difference in power rating? A: The RRS1K0E is rated for 500W power dissipation. The original RT230AS1001KB power rating is not specified in available documentation. The RRS1K0E provides adequate power handling for typical linear potentiometer applications.

Q: Is the RRS1K0E RoHS compliant? A: Yes, the RRS1K0E is ROHS3 compliant, meeting current environmental regulations. Both components have moisture sensitivity levels classified as Not Applicable.

Q: What is the rotation angle of the substitute? A: The RRS1K0E provides 325° rotation, enabling precise adjustment across the full resistance range in a single-turn configuration.
