Honeywell 43C15K Potentiometer: Equivalent & Substitute Parts

Part Overview

The Honeywell 43C15K is a 5k Ohm, 2W wirewound linear potentiometer designed for panel mount applications. This component features a 1-turn rotational design with solder lug termination and a 300° rotation angle. The 43C15K is classified as obsolete, making identification of compatible substitute components essential for ongoing system maintenance and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Honeywell 43C15K is determined by the following critical parameters:

Core Electrical Parameters:

• Resistance value: 5k Ohm (exact match required)
• Taper characteristic: Linear (exact match required)
• Number of turns: 1 (exact match required)
• Resistive material: Wirewound (exact match required)

Mechanical Compatibility Parameters:

• Termination style: Solder Lug (exact match required)
• Mounting type: Panel Mount (exact match required)
• Bushing thread: 3/8-32 (exact match required)
• Actuator diameter: 0.250" (6.35mm) (exact match required)
• Rotation angle: 300° (exact match required)

Allowable Variation Parameters:

• Power rating: May exceed 2W (higher power rating acceptable for same electrical load)
• Tolerance: May differ within component specifications
• Actuator length: May vary within mechanical envelope constraints
• Body diameter: May vary within panel cutout constraints

The CTS Electrocomponents 026TB32R502B1A1 meets all core electrical and mechanical compatibility requirements for direct substitution.

Engineering Selection Recommendations

The CTS Electrocomponents 026TB32R502B1A1 is a direct functional substitute for the obsolete Honeywell 43C15K potentiometer. Selection is based on the following factors:

Product Status Consideration: The Honeywell 43C15K is classified as obsolete. The CTS 026TB32R502B1A1 maintains active product status, ensuring availability for procurement and ongoing supply chain support.

Compliance and Certification: Both components meet RoHS compliance requirements. The CTS part carries ROHS3 Compliant status and REACH Unaffected designation, providing regulatory alignment for current manufacturing standards.

Electrical and Mechanical Equivalence: All critical parameters match between the two components: 5k Ohm resistance, linear taper, 1-turn configuration, wirewound construction, solder lug termination, 3/8-32 bushing thread, and 300° rotation angle.

Power Rating Enhancement: The CTS substitute provides a 5W power rating compared to the 2W rating of the original component. This higher rating does not create incompatibility and provides additional thermal margin in applications operating at or near the original 2W specification.

Inventory Availability: The CTS 026TB32R502B1A1 is available in active inventory (3316 pieces), supporting both immediate replacement needs and future procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can the CTS 026TB32R502B1A1 be used as a direct replacement for the Honeywell 43C15K in existing assemblies?

A: Yes. The CTS part matches all critical electrical and mechanical parameters: 5k Ohm resistance, linear taper, 1-turn design, wirewound construction, solder lug termination, 3/8-32 bushing thread, and 300° rotation angle. Panel mount configuration and actuator specifications are identical.

Q: What is the significance of the higher 5W power rating on the CTS substitute?

A: The CTS 026TB32R502B1A1 provides a 5W power rating versus the 2W rating of the original Honeywell component. This higher rating is compatible with applications designed for 2W operation and provides additional thermal capacity without affecting electrical performance or mechanical fit.

Q: Does the tolerance difference between ±5% (Honeywell) and ±20% (CTS) affect substitution suitability?

A: Tolerance differences must be evaluated within the context of the specific application circuit. The ±20% tolerance of the CTS part is acceptable for general potentiometer applications. Applications requiring tighter tolerance control should specify this requirement during component selection.

Q: Are there any packaging or inventory considerations for the CTS substitute?

A: The CTS 026TB32R502B1A1 is supplied in bulk packaging. The component is available in active inventory with 3316 pieces in stock, supporting both prototype and production volume requirements.

Q: What compliance certifications apply to the CTS substitute?

A: The CTS 026TB32R502B1A1 carries ROHS3 Compliant status and REACH Unaffected designation. Both components are classified under ECCN EAR99 and HTSUS 8533.31.0000.

Q: Are the physical dimensions compatible with existing panel cutouts designed for the Honeywell 43C15K?

A: The bushing thread specification (3/8-32) and actuator diameter (0.250" / 6.35mm) are identical between components. The CTS body diameter is 0.937" (23.80mm) compared to the Honeywell 1.126" (28.60mm). Verify that the existing panel cutout accommodates the CTS body diameter, or confirm that the larger Honeywell body diameter was not a design constraint.
