Key Parameters

Substitute Part Grouping Explanation

Substitution of the RT100AS1002KB is determined by strict equivalence across the following critical parameters: resistance value (10k Ohm), power rating (100W), resistive material (wirewound), number of turns (1.0), mounting configuration (panel mount), and termination method (solder lug). The substitute part RKS10KE meets all these core electrical and mechanical requirements. Variations in secondary parameters such as taper type, actuator geometry, and bushing thread specifications do not preclude functional substitution when the primary performance criteria are satisfied.

Parameter Comparison

Engineering Selection Recommendations

The RKS10KE represents a direct functional equivalent to the obsolete RT100AS1002KB. Both components share identical electrical specifications (10k Ohm, 100W, ±10% tolerance) and mechanical mounting configuration (panel mount, solder lug termination). The RKS10KE maintains active product status with ROHS3 compliance and EAR99 export classification, ensuring availability and regulatory alignment for current applications. Physical differences in actuator design and bushing thread specification do not impact electrical performance or core mechanical compatibility in standard panel mount installations.

Frequently Asked Questions (FAQ)

Q: Can the RKS10KE directly replace the RT100AS1002KB in existing assemblies?

A: Yes. Both potentiometers share identical resistance (10k Ohm), power rating (100W), wirewound construction, 1-turn configuration, panel mount design, and solder lug termination. These parameters define functional equivalence for this component category.

Q: What are the differences between these two potentiometers?

A: The RKS10KE includes a linear taper specification, whereas the RT100AS1002KB does not specify taper. The RKS10KE features a flatted actuator and includes bushing thread specification (3/8-32), while the RT100AS1002KB specifies a round actuator. The RKS10KE body diameter is 3.125" (79.38mm) and actuator length is 0.875" (22.23mm), compared to the RT100AS1002KB actuator length of 0.984" (25.00mm). These mechanical variations do not affect electrical substitution.

Q: Why is the RT100AS1002KB obsolete?

A: The RT100AS1002KB is classified as obsolete by the manufacturer. The RKS10KE, maintained in active production status by Ohmite, provides equivalent electrical performance and is recommended for new designs and replacement applications.

Q: Are there inventory considerations for substitution?

A: The RKS10KE is available with 1004 pieces in stock as new original inventory, ensuring supply continuity for applications requiring this 10k Ohm, 100W wirewound potentiometer specification.

Q: Does the RKS10KE meet current regulatory requirements?

A: Yes. The RKS10KE is ROHS3 compliant and classified as EAR99 for export purposes, meeting current regulatory standards for electronic component applications.
