Honeywell 53C1100KZ Potentiometer - Equivalent & Substitute Parts

Part Overview

The Honeywell 53C1100KZ is a 100k Ohm, 2-watt logarithmic panel mount potentiometer with conductive plastic resistive material and solder lug termination. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing maintenance, repair, and design continuity in applications requiring logarithmic taper potentiometers with identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Honeywell 53C1100KZ is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 100k Ohm
• Power rating: 2W
• Taper characteristic: Logarithmic
• Tolerance: ±10%
• Number of gangs: 1 (single gang)
• Number of turns: 1.0

Mechanical Parameters:

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

The Ohmite CA1041E meets all specified electrical and mechanical parameters. The primary difference is the resistive material composition (carbon versus conductive plastic), which does not affect functional equivalence for applications requiring logarithmic response characteristics at the specified power and resistance ratings.

Parameter Comparison

Engineering Selection Recommendations

The Ohmite CA1041E is a direct functional equivalent for the obsolete Honeywell 53C1100KZ potentiometer. Both components satisfy identical electrical specifications (100k Ohm, 2W, logarithmic taper, ±10% tolerance) and mechanical requirements (panel mount, 3/8-32 bushing, solder lug termination, 312° rotation).

Compliance Status:

• Honeywell 53C1100KZ: RoHS Compliant
• Ohmite CA1041E: ROHS3 Compliant

Both components meet current regulatory requirements. The Ohmite CA1041E carries active product status with confirmed inventory availability (1081 pcs), whereas the Honeywell component is obsolete. The resistive material difference (carbon in the substitute versus conductive plastic in the original) does not affect functional performance for applications requiring logarithmic response at the specified power and resistance ratings.

Frequently Asked Questions (FAQ)

Q: Can the Ohmite CA1041E directly replace the Honeywell 53C1100KZ in existing applications?

A: Yes. Both components share identical electrical parameters (100k Ohm, 2W, logarithmic taper), mechanical dimensions (panel mount, 3/8-32 bushing, 2.000" actuator length, 0.250" diameter), and termination style (solder lug). Physical installation and electrical performance are equivalent.

Q: What is the difference between conductive plastic and carbon resistive materials in these potentiometers?

A: The resistive material composition differs between the two components. The Honeywell 53C1100KZ uses conductive plastic, while the Ohmite CA1041E uses carbon. Both materials deliver the specified logarithmic taper characteristic and 2-watt power rating. Material selection does not affect functional equivalence for applications requiring the specified electrical and mechanical parameters.

Q: Why is the Honeywell 53C1100KZ classified as obsolete?

A: The Honeywell 53C1100KZ has reached end-of-life status. The Ohmite CA1041E provides functional continuity for applications requiring 100k Ohm, 2-watt logarithmic panel mount potentiometers with identical specifications.

Q: Are there packaging differences between these components?

A: The Honeywell 53C1100KZ is packaged in standard format, while the Ohmite CA1041E is supplied in bulk packaging. Both are suitable for direct component substitution in circuit applications.

Q: Do both components meet current regulatory compliance standards?

A: Yes. The Honeywell 53C1100KZ is RoHS Compliant, and the Ohmite CA1041E is ROHS3 Compliant. Both meet current environmental and regulatory requirements. Both components carry MSL 1 (Unlimited) moisture sensitivity classification.

Q: What is the rotation specification, and does it affect substitution?

A: Both components feature 312° rotation, which defines the mechanical travel range of the potentiometer shaft. This specification is identical between the main part and substitute, ensuring equivalent mechanical performance in panel mount applications.
