Key Parameters

Substitute Part Grouping Explanation

Substitution of the RT100AS5001KB is determined by strict equivalence across the following critical parameters:

• Resistance value: 5k Ohm (exact match required)
• Power rating: 100W (exact match required)
• Resistive material: Wirewound (exact match required)
• Number of turns: 1.0 (exact match required)
• Rotation angle: 300° (exact match required)
• Mounting configuration: Panel Mount (exact match required)
• Termination: Solder Lug (exact match required)
• Tolerance: ±10% (exact match required)

The RKS5K0E from Ohmite meets all mandatory electrical and mechanical parameters for direct substitution. Both components share identical resistance, power rating, wirewound construction, single-turn configuration, rotation specification, panel mount design, and solder lug termination.

Parameter Comparison

Engineering Selection Recommendations

The RKS5K0E is the qualified substitute for the RT100AS5001KB. The Ohmite component maintains active product status, ensuring continued availability and supply chain reliability. The RKS5K0E carries ROHS3 compliance certification, meeting current environmental and regulatory standards for electronic component manufacturing and deployment.

Physical differences exist in actuator geometry and bushing specifications between the two components. The RT100AS5001KB features a round actuator (0.984" length, 0.236" diameter), while the RKS5K0E uses a flatted actuator (0.875" length, 0.250" diameter) with a 3/8-32 bushing thread. These dimensional variations require mechanical fit verification in panel mount applications before final component selection.

Frequently Asked Questions (FAQ)

Q: Can the RKS5K0E directly replace the RT100AS5001KB in all applications?

A: The RKS5K0E matches all critical electrical parameters and meets the functional specification of the RT100AS5001KB. However, physical mounting geometry differs. Verify that the flatted actuator design and bushing thread specification (3/8-32) are compatible with your panel mount configuration before installation.

Q: What is the significance of the obsolete status of the RT100AS5001KB?

A: Obsolete status indicates that the Vishay Sfernice RT100AS5001KB is no longer in active production. The RKS5K0E maintains active status, providing assured long-term availability and supply continuity for applications requiring this 5k Ohm, 100W wirewound potentiometer specification.

Q: Are there differences in taper characteristics between these components?

A: The RT100AS5001KB does not specify a taper characteristic in the provided data. The RKS5K0E is specified as linear taper. Confirm that linear taper operation is acceptable for your application requirements.

Q: What compliance certifications apply to each component?

A: The RKS5K0E carries ROHS3 compliance certification. The RT100AS5001KB compliance status is not specified in the available data. If ROHS3 compliance is a requirement for your application, the RKS5K0E satisfies this criterion.

Q: How do the actuator specifications differ?

A: The RT100AS5001KB uses a round actuator measuring 0.984" (25.00mm) in length with a 0.236" (6.00mm) diameter. The RKS5K0E uses a flatted actuator measuring 0.875" (22.23mm) in length with a 0.250" (6.35mm) diameter. Verify mechanical compatibility with your panel cutout and control interface design.
