Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Honeywell 43C110 must satisfy the following core electrical and mechanical parameters:

Mandatory Matching Parameters:

• Resistance value: 10 Ohms
• Taper type: Linear
• Number of turns: 1
• Number of gangs: 1
• Rotation angle: 300°
• Resistive material: Wirewound
• Termination style: Solder Lug
• Mounting type: Panel Mount
• Bushing thread: 3/8-32
• Actuator type: Round
• Actuator diameter: 0.250" (6.35mm)

Allowable Variation Parameters:

• Power rating: May exceed 2W (higher power rating provides operational margin)
• Tolerance: May differ from ±5% (component-specific specification)
• Body diameter: Minor dimensional variation acceptable within mechanical envelope constraints
• Actuator length: Variation acceptable based on application requirements

The CTS Electrocomponents 026TB32R100B1A1 qualifies as a substitute based on matching all mandatory parameters while providing enhanced power handling at 5W.

Parameter Comparison

Engineering Selection Recommendations

Honeywell 43C110 Status: The 43C110 is classified as obsolete. Current inventory availability is 1030 pieces in new original condition. This component is RoHS Compliant and REACH Unaffected, meeting current environmental compliance standards.

CTS 026TB32R100B1A1 Substitute Qualification: The CTS 026TB32R100B1A1 is an active product with 1115 pieces in current inventory. This substitute maintains all critical electrical and mechanical parameters required for functional equivalence. The substitute provides ROHS3 Compliance and REACH Unaffected status, ensuring regulatory alignment with modern manufacturing requirements.

Key Differences Affecting Selection:

The CTS substitute provides 5W power rating compared to the original 2W specification, offering enhanced thermal margin for applications operating near maximum power dissipation limits. The tolerance specification differs at ±20% versus ±5%, which may impact precision-dependent applications requiring tighter resistance control.

Body diameter reduction from 1.126" to 0.937" and actuator length reduction from 2.000" to 1.000" represent mechanical envelope changes. These dimensional variations require verification against specific panel mounting and mechanical clearance constraints in the target application.

Compliance Basis: Both components satisfy ECCN EAR99 classification and HTSUS 8533.31.0000 commodity code requirements. Selection between the original and substitute should be based on application-specific power dissipation requirements, tolerance specifications, and mechanical envelope constraints.

Frequently Asked Questions (FAQ)

Q: Can the CTS 026TB32R100B1A1 directly replace the Honeywell 43C110 in all applications?

A: The CTS substitute matches all mandatory electrical and mechanical parameters including resistance, taper, rotation, termination, and mounting specifications. However, dimensional differences in body diameter and actuator length require verification against specific panel mounting geometry and mechanical clearance requirements in your application.

Q: What is the significance of the power rating difference between 2W and 5W?

A: The 5W rating on the substitute provides additional thermal capacity. Applications operating at or near the original 2W specification will function within the substitute's operational envelope. Applications requiring precise power dissipation characteristics should evaluate whether the higher rating affects thermal behavior in the specific circuit context.

Q: Does the tolerance difference from ±5% to ±20% affect substitution suitability?

A: Tolerance specification is application-dependent. The ±20% tolerance on the substitute is wider than the original ±5%. Applications requiring precise resistance values within ±5% tolerance must evaluate whether the substitute's ±20% specification meets circuit performance requirements.

Q: Are there mechanical installation considerations due to dimensional changes?

A: Yes. The substitute features a smaller body diameter (0.937" versus 1.126") and shorter actuator length (1.000" versus 2.000"). Panel cutout dimensions, mounting bracket geometry, and actuator clearance must be verified to ensure the substitute fits within the existing mechanical envelope.

Q: What is the product status significance?

A: The Honeywell 43C110 is obsolete, meaning Honeywell no longer manufactures this component. The CTS 026TB32R100B1A1 is active production, ensuring long-term availability and supply chain continuity for new designs and ongoing production requirements.

Q: Are both components RoHS and REACH compliant?

A: Yes. The Honeywell 43C110 is RoHS Compliant and REACH Unaffected. The CTS 026TB32R100B1A1 is ROHS3 Compliant and REACH Unaffected. Both components meet current environmental and regulatory compliance standards.

Q: What packaging differences exist between these components?

A: The Honeywell 43C110 is supplied in standard packaging. The CTS 026TB32R100B1A1 is supplied in bulk packaging. Packaging format may affect procurement quantities and handling procedures but does not impact electrical or mechanical functionality.
