Equivalent & Substitute Parts for Honeywell 58C1-10K Wirewound Potentiometer

Part Overview

The Honeywell 58C1-10K is a 10k Ohm, 4W wirewound linear potentiometer designed for panel mount applications with a 300° rotation and solder lug termination. This component is classified as obsolete, necessitating identification of active substitute parts to maintain design continuity and ensure supply chain availability for new production and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Honeywell 58C1-10K is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Resistance value of 10k Ohm
• Linear taper characteristic
• Single-turn (1.0 Kierros) configuration
• 300° rotation angle
• Wirewound resistive material
• Solder lug termination
• Panel mount configuration with 3/8-32 bushing thread
• 0.250" (6.35mm) actuator diameter
• Single gang (1 Gang) design
• No built-in switch

Allowable Variation Parameters:

• Power rating: Substitute must equal or exceed 4W minimum
• Tolerance: Substitute tolerance may differ from ±5%
• Physical body dimensions: Minor variations acceptable if mounting interface remains compatible
• Actuator length: Variation acceptable if functional reach is maintained
• Product status: Active status preferred for supply continuity
• Compliance certifications: Equivalent or superior compliance acceptable

The CTS Electrocomponents 026TB32R103B1A1 qualifies as a direct substitute based on matching all mandatory parameters while exceeding the power rating requirement (5W vs. 4W) and maintaining compatible mechanical interfaces.

Engineering Selection Recommendations

Primary Substitute: CTS Electrocomponents 026TB32R103B1A1

The CTS 026TB32R103B1A1 is the qualified substitute for the obsolete Honeywell 58C1-10K based on the following engineering criteria:

Functional Compatibility: All critical electrical and mechanical parameters align with the original specification. The 10k Ohm resistance, linear taper, single-turn configuration, 300° rotation, wirewound construction, and solder lug termination are identical. The 3/8-32 bushing thread and 0.250" actuator diameter ensure direct mechanical compatibility with existing panel mount installations.

Performance Enhancement: The CTS substitute provides a 5W power rating, exceeding the original 4W specification. This represents a performance improvement with no functional degradation in the application circuit.

Supply Chain Advantage: The CTS part maintains active product status with 11,585 units in stock, compared to the obsolete Honeywell part with limited remaining inventory (734 units). This ensures long-term availability for production and field service requirements.

Compliance Status: Both components maintain RoHS and REACH compliance. The CTS part carries ROHS3 certification, meeting current regulatory requirements.

Tolerance Consideration: The CTS substitute specifies ±20% tolerance compared to the original ±5% tolerance. Applications requiring tighter tolerance control must evaluate this parameter against circuit performance requirements. For general potentiometer applications, ±20% tolerance is within acceptable limits for user-adjustable components.

Frequently Asked Questions (FAQ)

Q: Can the CTS 026TB32R103B1A1 be used as a direct replacement in existing Honeywell 58C1-10K applications?

A: Yes. The CTS part matches all critical parameters including resistance value, taper type, rotation angle, termination style, and mechanical mounting interface. Direct substitution is supported without circuit modification.

Q: What is the significance of the 5W power rating on the CTS substitute versus the 4W original?

A: The higher power rating indicates the substitute can dissipate more thermal energy without exceeding temperature limits. This provides additional design margin and does not create compatibility issues. The substitute will perform identically in applications designed for 4W operation.

Q: Does the ±20% tolerance of the CTS part affect circuit performance?

A: Tolerance impact depends on application requirements. For general potentiometer applications where the component serves as a user-adjustable control element, ±20% tolerance is acceptable. For precision measurement or calibration circuits requiring tighter tolerance, tolerance specifications must be evaluated against circuit design parameters.

Q: Are the physical dimensions compatible with existing panel cutouts and mounting hardware?

A: Yes. Both components share identical bushing thread specifications (3/8-32) and actuator diameter (0.250"). The CTS body diameter is smaller (0.937" vs. 1.690"), which does not affect mounting compatibility as the bushing thread and actuator interface remain identical. Existing panel cutouts and mounting hardware are compatible.

Q: What is the difference in actuator length between the two parts?

A: The Honeywell original has a 2.000" (50.80mm) actuator length, while the CTS substitute has a 1.000" (25.40mm) actuator length. This difference affects the physical reach of the control knob. If the application requires a specific actuator length for ergonomic or spatial reasons, this parameter must be evaluated. Standard potentiometer knobs are available in various sizes and can be selected to match application requirements.

Q: Is the CTS part suitable for new product designs?

A: Yes. The CTS 026TB32R103B1A1 is an active product with full manufacturing support and supply availability. It is suitable for both replacement applications and new product designs requiring 10k Ohm wirewound linear potentiometers with panel mount configuration.

Q: What compliance certifications apply to the CTS substitute?

A: The CTS part carries ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for electronic components in most markets. Both the original and substitute maintain equivalent compliance standing.
