Key Parameters

Substitute Part Grouping Explanation

The RKS200E from Ohmite qualifies as a substitute based on the following critical parameters:

• Power Rating Match: Both components are rated at 100W, meeting thermal and electrical load requirements
• Resistive Material Match: Both utilize wirewound construction, ensuring comparable frequency response and noise characteristics
• Termination Match: Both employ solder lug termination, maintaining electrical connection compatibility
• Mounting Type Match: Both are panel mount configurations
• Number of Turns Match: Both feature 1-turn adjustment
• Tolerance Match: Both maintain ±10% tolerance specification
• Rotation Match: Both provide 300° rotation range

The resistance value differs by 10 Ohms (200 Ohms vs. 220 Ohms), which falls within the ±10% tolerance band of the original specification, permitting functional substitution in applications where this variance is acceptable within circuit design parameters.

Parameter Comparison

Engineering Selection Recommendations

The RKS200E represents a direct functional substitute for the RT100AL2200KB based on matching electrical and mechanical specifications. The primary advantage of selecting the RKS200E is its active product status, ensuring continued availability and supply chain reliability compared to the obsolete RT100AL2200KB.

The RKS200E carries ROHS3 compliance certification, meeting current environmental and regulatory standards for electronic component manufacturing. This compliance status supports integration into systems requiring adherence to modern environmental directives.

The 10 Ohm resistance differential (200 Ohms vs. 220 Ohms) represents a 4.5% variance, remaining within the ±10% tolerance specification of both components. Circuit designers must evaluate whether this variance impacts system performance within their specific application context.

Frequently Asked Questions (FAQ)

Q: Can the RKS200E directly replace the RT100AL2200KB in existing assemblies?

A: Yes, the RKS200E provides direct mechanical and electrical compatibility. Both components share identical mounting type, termination style, power rating, and adjustment characteristics. The 10 Ohm resistance difference falls within the ±10% tolerance band of both specifications.

Q: What is the significance of the product status difference?

A: The RT100AL2200KB is classified as obsolete, indicating discontinued manufacturing and limited availability. The RKS200E maintains active product status, ensuring reliable supply chain access and ongoing manufacturer support for technical documentation and specifications.

Q: Are there mechanical dimension differences between these components?

A: Yes. The RT100AL2200KB features an actuator length of 0.984" (25.00mm) with 0.236" (6.00mm) diameter. The RKS200E specifies an actuator length of 0.875" (22.23mm) with 0.250" (6.35mm) diameter. Panel cutout and mounting bracket designs must accommodate these dimensional variations.

Q: Does the RKS200E meet current environmental compliance requirements?

A: The RKS200E carries ROHS3 compliance certification and REACH unaffected status, meeting current environmental and regulatory standards for electronic component manufacturing and distribution.

Q: What taper characteristic does the RKS200E provide?

A: The RKS200E features linear taper, providing proportional resistance change across the full rotation range. The original RT100AL2200KB taper specification was not provided in the reference data.
