RT100AS10R0KB Equivalent & Substitute Parts

Part Overview

The RT100AS10R0KB is a 10 Ohm, 100W wirewound potentiometer manufactured by Vishay Sfernice, designed for panel mount applications with a 1-turn adjustment mechanism and solder lug termination. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance, repair, and new design implementations where legacy component specifications must be maintained.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RT100AS10R0KB is determined by strict equivalence across the following critical parameters:

• Resistance value: 10 Ohms (exact match required)
• Power rating: 100W (exact match required)
• Resistive material: Wirewound (exact match required)
• Number of turns: 1 (exact match required)
• Mounting configuration: Panel Mount (exact match required)
• Termination: Solder Lug (exact match required)
• Tolerance: ±10% (exact match required)
• Rotation angle: 300° (exact match required)

The RKS10RE from Ohmite meets all mandatory electrical and mechanical parameters for direct substitution. Variations in actuator geometry, taper characteristics, and bushing specifications do not affect functional equivalence when the core electrical and mounting parameters remain constant.

Parameter Comparison

Engineering Selection Recommendations

The RKS10RE is the direct functional equivalent for the obsolete RT100AS10R0KB. Selection of the RKS10RE is supported by:

• Identical electrical specifications across all critical parameters (resistance, power rating, tolerance, rotation)
• Matching mechanical configuration (panel mount, solder lug termination, 1-turn wirewound design)
• Active product status ensuring ongoing availability and supply chain continuity
• ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for new designs and system upgrades

The RKS10RE maintains full functional compatibility with applications originally specified for the RT100AS10R0KB.

Frequently Asked Questions (FAQ)

Q: Can the RKS10RE be used as a direct replacement for the RT100AS10R0KB?

A: Yes. Both components share identical electrical specifications (10 Ohms, 100W, ±10% tolerance, 1-turn wirewound) and mechanical mounting configuration (panel mount, solder lug termination, 300° rotation). The RKS10RE is functionally equivalent and suitable for direct substitution.

Q: What are the differences between these two potentiometers?

A: The primary differences are non-functional: the RKS10RE features a flatted actuator versus the round actuator of the RT100AS10R0KB, a linear taper specification, and different physical dimensions. The RKS10RE also includes ROHS3 compliance and REACH unaffected status. These differences do not affect electrical performance or core mechanical compatibility.

Q: Why is the RT100AS10R0KB listed as obsolete?

A: The RT100AS10R0KB is classified as obsolete by the manufacturer, indicating it is no longer in active production. The RKS10RE from Ohmite is an active product with equivalent specifications, making it the appropriate choice for new designs and system replacements.

Q: Are there any compatibility concerns with panel mount installation?

A: Both components are specified for panel mount applications with solder lug termination. Minor differences in actuator length (RT100AS10R0KB: 0.984" vs. RKS10RE: 0.875") and bushing thread specifications (RKS10RE: 3/8-32) should be verified against specific panel cutout and mounting hardware requirements in your application.

Q: Does the RKS10RE meet current regulatory standards?

A: Yes. The RKS10RE is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components in most jurisdictions.
