RT100AS22R0KB Equivalent & Substitute Parts

Part Overview

The RT100AS22R0KB is a 22 Ohm, 100W wirewound potentiometer manufactured by Vishay Sfernice, designed for panel mount applications with a 1-turn rotation and solder lug termination. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations where this specification remains applicable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RT100AS22R0KB is determined by matching the following critical parameters:

• Resistance value: 22 Ohm (exact match required)
• Resistive material: Wirewound (maintains thermal and electrical characteristics)
• Number of turns: 1 (functional equivalence for adjustment range)
• Termination style: Solder Lug (mechanical and electrical interface compatibility)
• Mounting type: Panel Mount (physical installation compatibility)
• Rotation: 300° (operational range compatibility)
• Tolerance: ±10% (electrical specification alignment)

The RJS22RE from Ohmite meets these core substitution criteria. While the power rating differs (50W versus 100W), this represents a derating scenario where the substitute operates within reduced power envelope specifications.

Parameter Comparison

Engineering Selection Recommendations

The RJS22RE serves as the primary substitute for the RT100AS22R0KB based on matching core electrical and mechanical parameters. The substitute maintains active product status with Ohmite, ensuring ongoing availability and supply chain continuity.

Power rating derating from 100W to 50W requires thermal load analysis within the application circuit. Applications operating below 50W continuous dissipation present no functional limitation. Applications requiring full 100W operation necessitate alternative component evaluation or thermal management modifications.

The RJS22RE carries RoHS3 compliance certification, providing environmental regulatory alignment for new designs and updated systems. The original RT100AS22R0KB lacks specified RoHS status due to obsolete classification.

Frequently Asked Questions (FAQ)

Q: Can the RJS22RE directly replace the RT100AS22R0KB in all applications?

A: Direct substitution is valid for applications where power dissipation remains at or below 50W. Applications requiring the full 100W rating require thermal analysis or alternative component selection.

Q: What are the mechanical compatibility considerations?

A: Both components feature panel mount configuration with solder lug termination and 300° rotation. The RJS22RE specifies a flatted actuator type versus the original round actuator; verify mechanical fit within the control interface assembly.

Q: Are there compliance differences between these components?

A: The RJS22RE is RoHS3 compliant and carries EAR99 ECCN classification. The RT100AS22R0KB is classified as obsolete with no current compliance documentation. New designs should specify the RJS22RE to meet current environmental standards.

Q: What is the inventory status for substitution?

A: The RJS22RE maintains active inventory status (905 Pcs available) through Ohmite distribution channels, ensuring reliable procurement for replacement and new applications.
