Honeywell 58C15K Potentiometer: Equivalent & Substitute Parts

Part Overview

The Honeywell 58C15K is a 5k Ohm wirewound potentiometer rated for 4W power dissipation, designed for panel mount applications with linear taper and 1.0 turn rotation. This component is classified as obsolete, making substitute parts necessary for ongoing production and maintenance applications. The 58C15K features a round actuator with solder lug termination and operates across a 300° rotation range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Honeywell 58C15K is determined by the following core parameters:

Critical Matching Parameters:

• Resistance value: 5k Ohm
• Taper type: Linear
• Number of turns: 1.0
• Resistive material: Wirewound
• Termination style: Solder Lug
• Mounting type: Panel Mount
• Bushing thread: 3/8-32
• Rotation range: 300°
• Number of gangs: 1

Allowable Variation Parameters:

• Power rating: Equal to or greater than 4W
• Tolerance: Within acceptable circuit design margins
• Physical dimensions: Compatible with panel mount cavity
• Actuator dimensions: Compatible with control interface

The CTS Electrocomponents 026TB32R502B1A1 qualifies as a substitute based on matching all critical parameters while exceeding the power rating requirement (5W vs. 4W) and maintaining mechanical compatibility.

Engineering Selection Recommendations

The CTS Electrocomponents 026TB32R502B1A1 is the qualified substitute for the obsolete Honeywell 58C15K based on the following engineering criteria:

Product Status Consideration: The Honeywell 58C15K is classified as obsolete, necessitating component substitution for new designs and ongoing production support. The CTS 026TB32R502B1A1 maintains active product status with confirmed inventory availability (3316 pcs in stock).

Compliance and Certification: Both components meet RoHS requirements. The CTS substitute carries ROHS3 compliance, representing current regulatory standards. Both components are classified as EAR99 for export control purposes and carry MSL Level 1 (unlimited moisture sensitivity protection).

Electrical Compatibility: The substitute provides equal resistance value (5k Ohm) and linear taper matching. The 5W power rating of the CTS component exceeds the 4W requirement of the original Honeywell part, providing additional thermal margin in applications. The tolerance specification of the substitute (±20%) is wider than the original (±5%), requiring circuit design verification if tolerance-critical applications are involved.

Mechanical Compatibility: All critical mechanical parameters align: identical bushing thread (3/8-32), matching rotation (300°), identical actuator diameter (0.250"), and equivalent panel mount configuration. The CTS component features a shorter actuator length (1.000" vs. 2.000"), which may require mechanical interface verification in applications with specific actuator reach requirements.

Frequently Asked Questions (FAQ)

Q: Can the CTS 026TB32R502B1A1 directly replace the Honeywell 58C15K in existing applications?

A: Direct replacement is possible for applications where the actuator length difference (1.000" vs. 2.000") does not conflict with the mechanical interface. The wider tolerance specification (±20% vs. ±5%) requires verification that circuit design does not depend on the tighter tolerance of the original component.

Q: What is the significance of the power rating difference (4W vs. 5W)?

A: The CTS substitute provides a higher power rating, which is advantageous for thermal performance. This allows the substitute to dissipate more power without exceeding temperature limits, providing additional operational margin in the application.

Q: Are there any compliance differences between the two components?

A: Both components are RoHS compliant and carry identical MSL Level 1 ratings. The CTS component carries ROHS3 certification, which represents current regulatory compliance standards. Both are classified as EAR99 for export control.

Q: How does the tolerance difference affect component selection?

A: The Honeywell 58C15K specifies ±5% tolerance, while the CTS 026TB32R502B1A1 specifies ±20% tolerance. Applications requiring precise resistance values should evaluate whether the wider tolerance of the substitute is acceptable within circuit design specifications.

Q: What mechanical considerations apply to the actuator length difference?

A: The CTS substitute features a 1.000" actuator length compared to the 2.000" length of the original Honeywell component. Applications with specific actuator reach requirements or mechanical constraints must verify that the shorter actuator length is compatible with the control interface design.

Q: Is the CTS component available in the same packaging as the Honeywell part?

A: The CTS 026TB32R502B1A1 is supplied in bulk packaging. Packaging format differences may affect procurement and handling procedures but do not impact electrical or mechanical compatibility.
