Key Parameters

Substitute Part Grouping Explanation

Substitution of the RT100AD1000KB is based on matching the following critical electrical and mechanical parameters:

• Resistance value: 100 Ohms
• Power dissipation capability: 100W
• Resistive element type: Wirewound construction
• Termination method: Solder Lug
• Mounting configuration: Panel Mount
• Adjustment range: 1-turn potentiometer
• Rotation angle: 300°
• Tolerance specification: ±10%

The RKS100E from Ohmite satisfies all mandatory substitution criteria. While minor differences exist in actuator geometry and taper specification, these do not affect electrical equivalence or functional compatibility in applications requiring the specified resistance, power handling, and termination characteristics.

Parameter Comparison

Engineering Selection Recommendations

The RKS100E is the qualified substitute for the RT100AD1000KB based on electrical and mechanical parameter equivalence. The primary advantage of selecting the RKS100E is its active product status, ensuring continued availability and supply chain reliability. The RKS100E carries ROHS3 compliance certification, meeting current environmental and regulatory standards for electronic component manufacturing and deployment.

Physical mounting compatibility is maintained through identical panel mount configuration and solder lug termination. The 100W power rating and wirewound construction preserve thermal and electrical performance characteristics required by applications originally designed for the RT100AD1000KB.

Frequently Asked Questions (FAQ)

Q: Can the RKS100E directly replace the RT100AD1000KB in existing assemblies?

A: Yes. Both components share identical electrical specifications (100 Ohm, 100W, ±10% tolerance, wirewound construction) and mechanical mounting interfaces (panel mount, solder lug termination, 300° rotation). Direct substitution is supported without circuit modification.

Q: What are the differences between these two potentiometers?

A: The primary differences are product status and compliance certification. The RT100AD1000KB is obsolete; the RKS100E is active production. The RKS100E includes ROHS3 compliance. Minor variations exist in actuator geometry (flatted vs. round) and taper specification (linear vs. unspecified), which do not affect electrical function or mounting compatibility.

Q: Is the RKS100E available in the same packaging as the RT100AD1000KB?

A: The RKS100E is supplied in bulk packaging. Both components are panel mount potentiometers with solder lug termination suitable for direct board integration. Packaging format does not affect functional equivalence.

Q: Are there any thermal or power handling differences?

A: No. Both components are rated for 100W continuous power dissipation and utilize wirewound resistive elements. Thermal performance and power handling capability are equivalent.

Q: What compliance standards apply to the RKS100E?

A: The RKS100E is ROHS3 compliant and carries EAR99 export classification. These certifications ensure compliance with current environmental regulations and international trade requirements.
