CT-6ES102 Trimmer Potentiometer Equivalent & Substitute Parts

Part Overview

The CT-6ES102 is a 1 kOhm, 0.5W through-hole trimmer potentiometer manufactured by Nidec Components Corporation. This cermet-based component features side adjustment with PC pin termination and is designed for applications requiring precision variable resistance in compact form factors. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility requirements are met within the same product category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CT-6ES102 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

• Resistance value: 1 kOhms (exact match required)
• Power rating: 0.5W / 1/2W (exact match required)
• Tolerance: ±10% (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Number of turns: 1 (exact match required)
• Adjustment type: Side Adjustment (exact match required)
• Resistive material: Cermet (exact match required)
• Mounting type: Through Hole (exact match required)
• Termination style: PC Pins (exact match required)
• Regulatory compliance: ROHS3 Compliant (minimum requirement)

The 72XR1KLF from TT Electronics/BI meets all electrical and functional specifications. Physical dimensions differ (square 0.375" x 0.375" versus rectangular 0.323" x 0.276"), which may affect board layout compatibility depending on available space constraints in the application.

Parameter Comparison

Engineering Selection Recommendations

Both the CT-6ES102 and 72XR1KLF are active production components with identical electrical specifications and ROHS3 compliance. Selection between these parts should be based on:

• Board layout space availability: The CT-6ES102 occupies a smaller rectangular footprint (8.20mm x 7.00mm) compared to the 72XR1KLF square footprint (9.53mm x 9.53mm)
• Supplier availability and lead time requirements
• Cost considerations based on current inventory levels
• Mechanical mounting constraints within the application

Both parts satisfy the same functional requirements and regulatory standards for this product category.

Frequently Asked Questions (FAQ)

Q: Can the 72XR1KLF be used as a direct replacement for the CT-6ES102?

A: Yes, electrically and functionally. Both parts share identical resistance, power rating, tolerance, temperature coefficient, adjustment type, and termination style. The primary consideration is physical dimension compatibility on the PCB, as the 72XR1KLF has a larger square footprint.

Q: What is the significance of the different physical dimensions?

A: The CT-6ES102 uses a rectangular form factor (8.20mm x 7.00mm) while the 72XR1KLF uses a square form factor (9.53mm x 9.53mm). This affects PCB layout and available mounting space. Verify that the larger 72XR1KLF footprint fits within your application's space constraints before substitution.

Q: Are both parts RoHS compliant?

A: Yes, both the CT-6ES102 and 72XR1KLF are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What does the ±10% tolerance mean for this trimmer potentiometer?

A: The resistance value will fall within ±10% of the nominal 1 kOhm specification across the operating range. Both substitute parts maintain this tolerance specification.

Q: Is the temperature coefficient specification the same for both parts?

A: Yes, both parts have a temperature coefficient of ±100ppm/°C, ensuring equivalent thermal stability across the operating temperature range.
