Key Parameters

Substitute Part Grouping Explanation

Substitution of the RT100AS1501KB is based on strict equivalence of the following critical parameters:

• Resistance value: 1.5k Ohm
• Power rating: 100W
• Resistive material: Wirewound construction
• Termination style: Solder Lug
• Mounting configuration: Panel Mount
• Number of turns: 1
• Tolerance: ±10%
• Rotation angle: 300°

The RKS1K5E from Ohmite meets all mandatory electrical and mechanical requirements for direct substitution. Both components share identical resistance, power handling, construction method, and mounting specifications. Mechanical variations in actuator geometry and bushing thread specifications do not affect functional equivalence in applications where the potentiometer serves as a variable resistor element.

Parameter Comparison

Engineering Selection Recommendations

The RKS1K5E represents the qualified substitute for the obsolete RT100AS1501KB. Selection of this alternative is supported by:

• Electrical equivalence across all specified parameters
• Active product status ensuring continued availability and supply chain reliability
• ROHS3 compliance certification, meeting current environmental and regulatory standards
• Identical power handling and resistive characteristics for direct functional replacement

The transition from RT100AS1501KB to RKS1K5E does not require circuit redesign or performance re-evaluation when substitution is limited to the resistive element function.

Frequently Asked Questions (FAQ)

Q: Can the RKS1K5E replace the RT100AS1501KB in existing assemblies?

A: Yes. Both components share identical electrical specifications (1.5k Ohm, 100W, wirewound, ±10% tolerance) and mounting configuration (panel mount, solder lug termination). Mechanical differences in actuator design do not affect substitution when the potentiometer functions as a variable resistor.

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

A: The RT100AS1501KB is classified as obsolete, indicating discontinued manufacturing and limited availability. The RKS1K5E maintains active status, ensuring reliable sourcing for current and future applications.

Q: Does the RKS1K5E meet current compliance requirements?

A: The RKS1K5E carries ROHS3 certification, confirming compliance with current environmental regulations. This certification is not specified for the obsolete RT100AS1501KB.

Q: Are there differences in mechanical dimensions that affect installation?

A: The RKS1K5E features a flatted actuator (0.875" length, 0.250" diameter) compared to the round actuator of the RT100AS1501KB (0.984" length, 0.236" diameter). The RKS1K5E includes a 3/8-32 bushing thread specification. These variations require verification of mechanical fit within the specific application enclosure or control panel.

Q: What packaging is available for the RKS1K5E?

A: The RKS1K5E is supplied in bulk packaging, with 795 pieces currently in stock.
