Key Parameters

Substitute Part Grouping Explanation

Substitution of the Honeywell 53C110K is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 10k Ohm
• Power rating: 2W
• Tolerance: ±10%
• Taper: Linear
• Number of gangs: 1 (single gang)
• Number of turns: 1

Mechanical Parameters:

• Termination style: Solder Lug
• Mounting type: Panel Mount
• Bushing thread: 3/8-32
• Actuator type: Round
• Actuator length: 2.000" (50.80mm)
• Actuator diameter: 0.250" (6.35mm)
• Rotation: 312°

The primary distinction between the main part and its substitute lies in the resistive material composition. The 53C110K utilizes conductive plastic, while the substitute employs carbon film technology. Both materials satisfy the electrical and mechanical requirements for this application category.

Engineering Selection Recommendations

For New Designs and Production Transition:

The Ohmite CU1031E serves as the direct substitute for the obsolete Honeywell 53C110K. Selection of the CU1031E is supported by the following factors:

Product Status: The CU1031E maintains active product status, ensuring continued availability and manufacturer support. The 53C110K is classified as obsolete, limiting future procurement options.

Compliance Certifications: Both components satisfy RoHS requirements. The CU1031E carries ROHS3 compliance, representing current regulatory standards. Both parts are classified under identical HTSUS code 8533.40.8070 and ECCN EAR99.

Electrical and Mechanical Equivalence: All critical electrical parameters (resistance, power rating, tolerance, taper) and mechanical parameters (termination, mounting, bushing thread, actuator dimensions, rotation angle) are identical between the two components.

Material Composition Difference: The CU1031E employs carbon film resistive material in place of the conductive plastic used in the 53C110K. This material change does not affect the specified electrical performance or mechanical compatibility within the defined parameter set.

Physical Envelope: The CU1031E body diameter measures 1.157" (29.40mm) compared to the 53C110K at 1.094" (27.78mm). This 0.063" (1.62mm) difference represents a minor variation that must be evaluated within the specific panel mounting application context.

Frequently Asked Questions (FAQ)

Q: Can the Ohmite CU1031E directly replace the Honeywell 53C110K in existing applications?

A: The CU1031E matches all specified electrical and mechanical parameters of the 53C110K. The primary consideration is the body diameter difference of 0.063" (1.62mm). Panel mounting applications with fixed hole spacing or dimensional constraints must accommodate this variation. Solder lug termination, bushing thread size, and actuator dimensions are identical.

Q: What is the significance of the resistive material difference between conductive plastic and carbon?

A: Both conductive plastic and carbon resistive materials satisfy the specified 10k Ohm resistance, ±10% tolerance, and 2-watt power rating. The material difference does not alter the electrical performance parameters provided in this specification. Material selection reflects manufacturing process differences between Honeywell and Ohmite.

Q: Are there compliance or certification differences between these components?

A: Both components are RoHS compliant. The CU1031E carries ROHS3 certification, representing current regulatory standards. The 53C110K is RoHS compliant. Both components share identical ECCN (EAR99) and HTSUS (8533.40.8070) classifications. The CU1031E is REACH Unaffected; the 53C110K does not specify REACH status.

Q: What inventory considerations apply to this substitution?

A: The Honeywell 53C110K maintains 1125 pieces in new original stock. The Ohmite CU1031E has 1120 pieces available in bulk packaging. Both components are currently in stock, supporting immediate procurement decisions.

Q: How does the packaging difference affect component selection?

A: The 53C110K is supplied in standard packaging format. The CU1031E is supplied in bulk packaging. Packaging format does not affect component functionality or electrical performance. Bulk packaging may influence handling procedures and inventory management protocols.

Q: Are the actuator specifications identical between these components?

A: Yes. Both components feature round actuators with 2.000" (50.80mm) length and 0.250" (6.35mm) diameter. Bushing thread specification (3/8-32) and rotation angle (312°) are identical. Panel mount adjustment type is equivalent for both components.
