Substitute Part Grouping Explanation

Substitution of the RT100AS1001KB is determined by the following critical electrical and mechanical parameters:

Electrical Equivalence Requirements:

  • Resistance value: 1k Ohm
  • Power rating: 100W minimum
  • Taper: Linear
  • Tolerance: ±10%
  • Termination: Solder Lug

Mechanical Compatibility Requirements:

  • Mounting type: Panel Mount
  • Number of gangs: 1
  • Number of turns: 1
  • Rotation range: 300°
  • Resistive material: Wirewound

The RKS1K0E manufactured by Ohmite meets all critical electrical parameters and mechanical mounting requirements. Both components share identical resistance, power rating, taper type, tolerance, and termination style. Both are panel mount wirewound potentiometers with single gang, single turn configuration and 300° rotation. Physical actuator dimensions differ slightly, but both accommodate standard panel mount installation with solder lug connections.

Engineering Selection Recommendations

The RKS1K0E is a direct functional equivalent for the obsolete RT100AS1001KB. Both components satisfy identical electrical specifications: 1k Ohm resistance, 100W power rating, linear taper, ±10% tolerance, and solder lug termination. Both are ROHS3 compliant and designed for panel mount applications.

The primary distinction is product status: the RT100AS1001KB is obsolete, while the RKS1K0E is active production. The RKS1K0E is currently available in inventory (820 Pcs), ensuring supply continuity for replacement and new applications.

Physical actuator dimensions vary between the two models. The RT100AS1001KB features a round actuator measuring 0.984" (25.00mm) length and 0.236" (6.00mm) diameter. The RKS1K0E uses a flatted actuator measuring 0.875" (22.23mm) length and 0.250" (6.35mm) diameter. Both accommodate standard panel mount installation with solder lug connections. Mechanical fit verification is required for applications with tight actuator clearance constraints.

Frequently Asked Questions (FAQ)

Q: Can the RKS1K0E directly replace the RT100AS1001KB in existing applications?

A: The RKS1K0E meets all critical electrical and mechanical specifications for panel mount wirewound potentiometer applications. Both components provide identical 1k Ohm resistance, 100W power rating, linear taper, and solder lug termination. Physical actuator dimensions differ slightly; verify that the flatted actuator design and dimensional changes accommodate your specific panel mount installation.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by resistance value (1k Ohm), power rating (100W), taper type (linear), tolerance (±10%), termination style (solder lug), mounting type (panel mount), number of gangs (1), number of turns (1), and rotation range (300°). The RKS1K0E satisfies all these parameters.

Q: Are both components RoHS compliant?

A: Yes. Both the RT100AS1001KB and RKS1K0E are ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the availability status of the substitute part?

A: The RKS1K0E is in active production with 820 Pcs currently in stock. The RT100AS1001KB is obsolete with limited remaining inventory (899 Pcs). The RKS1K0E ensures long-term supply availability for ongoing applications.

Q: Are there packaging differences between the two parts?

A: The RT100AS1001KB is supplied in standard packaging. The RKS1K0E is supplied in bulk packaging. Both are suitable for solder lug termination and panel mount installation.
