Key Parameters

Substitute Part Grouping Explanation

Substitution of the RT100AL10R0KB is determined by strict equivalence across the following critical parameters:

• Resistance Value: 10 Ohms (exact match required)
• Power Dissipation: 100W (exact match required)
• Resistive Technology: Wirewound (required for power handling and stability)
• Termination: Solder Lug (required for circuit integration)
• Mounting Configuration: Panel Mount (required for mechanical fit)
• Adjustment Mechanism: 1-turn potentiometer (required for control range)
• Tolerance: ±10% (acceptable range for resistance accuracy)

The RKS10RE from Ohmite meets all mandatory electrical and mechanical parameters. While minor differences exist in actuator geometry and taper specification, these do not affect functional equivalence for the core potentiometer application.

Parameter Comparison

Engineering Selection Recommendations

The RKS10RE is the direct functional equivalent for RT100AL10R0KB replacement. Selection is based on the following engineering criteria:

Electrical Equivalence: Both components provide identical resistance (10 Ohms), power handling (100W), tolerance (±10%), and wirewound construction. Functional performance in circuit applications is equivalent.

Mechanical Compatibility: Both components feature panel mount configuration, solder lug termination, 1-turn adjustment, and 300° rotation. Physical integration into existing assemblies is compatible.

Product Status: The RT100AL10R0KB is obsolete, while RKS10RE is active production. The active status of RKS10RE ensures continued availability and supply chain reliability.

Compliance: RKS10RE carries ROHS3 compliance and REACH unaffected status, meeting modern regulatory requirements for new designs and system updates.

Frequently Asked Questions (FAQ)

Q: Can RKS10RE directly replace RT100AL10R0KB in existing circuits?

A: Yes. Both components share identical electrical specifications (10 Ohms, 100W, ±10% tolerance, wirewound construction) and mechanical mounting (panel mount, solder lug termination, 1-turn adjustment). Functional substitution is direct.

Q: What are the differences between these two potentiometers?

A: The primary differences are manufacturer (Vishay Sfernice vs. Ohmite), product status (obsolete vs. active), and minor actuator geometry variations. These differences do not affect electrical or mechanical performance in standard applications.

Q: Is the RKS10RE available in the same packaging as the RT100AL10R0KB?

A: RKS10RE is supplied in bulk packaging. Both components are panel mount potentiometers with solder lug termination suitable for direct circuit integration.

Q: Does RKS10RE meet current regulatory standards?

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

Q: Are there any performance differences in power dissipation or temperature stability?

A: Both components are rated for 100W power dissipation with wirewound resistive elements. No performance differences are specified in the provided technical parameters.
