Key Parameters

Substitute Part Grouping Explanation

Substitution of the RT100AS13R0KB is determined by the following critical parameters:

• Power Rating: 100W minimum requirement for thermal performance equivalence
• Resistive Material: Wirewound construction for load handling and stability
• Mounting Configuration: Panel mount with solder lug termination for mechanical and electrical compatibility
• Resistance Value: 13 Ohms nominal with ±10% tolerance band
• Rotation Angle: 300° mechanical rotation for control range consistency
• Number of Turns: Single-turn potentiometer for linear adjustment characteristics

The RKS15RE from Ohmite meets these core substitution criteria while offering active product status and current manufacturing availability.

Parameter Comparison

Engineering Selection Recommendations

The RKS15RE represents a direct functional substitute for the obsolete RT100AS13R0KB. Both components share identical power ratings, wirewound construction, panel mount configuration, and solder lug termination. The resistance differential of 2 Ohms (13 Ohms versus 15 Ohms) falls within the ±10% tolerance specification of both parts, permitting electrical interchangeability in applications where the nominal resistance value does not require exact matching.

The RKS15RE offers the advantage of active product status with confirmed manufacturing availability and ROHS3 compliance certification, addressing regulatory and supply chain considerations for new designs and system updates. The component is currently in stock with 873 units available.

Frequently Asked Questions (FAQ)

Q: Can the RKS15RE directly replace the RT100AS13R0KB in existing assemblies?

A: Yes. Both potentiometers share identical power ratings (100W), resistive material (wirewound), mounting type (panel mount), termination style (solder lug), and mechanical rotation (300°). The 2 Ohm resistance difference (13 Ohms to 15 Ohms) is within the ±10% tolerance band of both components.

Q: What is the significance of the resistance value difference?

A: The RT100AS13R0KB operates at 13 Ohms nominal, while the RKS15RE operates at 15 Ohms nominal. This 15.4% difference in absolute value remains within the ±10% tolerance specification of both parts. Circuit designs must verify that this resistance variance does not impact system performance or control range requirements.

Q: Are there mechanical compatibility considerations?

A: Both components feature panel mount configuration with solder lug termination. The RKS15RE includes a 3/8-32 bushing thread and round body measuring 3.125" diameter, compared to unspecified body dimensions for the RT100AS13R0KB. Physical mounting verification is required for panel cutout and bushing compatibility.

Q: What is the compliance status of each component?

A: The RT100AS13R0KB is classified as obsolete with no current RoHS status specified. The RKS15RE is an active product with ROHS3 compliance certification, meeting current environmental and regulatory requirements for new system designs.

Q: Is the RKS15RE available for immediate procurement?

A: Yes. The RKS15RE is currently in stock with 873 units available as new original inventory, providing supply chain continuity for replacement and new design applications.
