CT-6ES103 Trimmer Potentiometer - Equivalent & Substitute Parts

Part Overview

The CT-6ES103 is a 10 kOhm, 0.5W through-hole trimmer potentiometer manufactured by Nidec Components Corporation. This cermet-based side-adjustment component is designed for PC pin termination in applications requiring precision variable resistance. The part maintains Active product status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified when equivalent electrical specifications and functional characteristics align within the allowed parameter tolerances for this trimmer potentiometer category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CT-6ES103 is determined by strict alignment of the following electrical and mechanical parameters:

• Resistance value: 10 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)
• RoHS compliance: ROHS3 Compliant (minimum requirement)

The 72XR10KLF from TT Electronics / BI Technologies meets all electrical parameter requirements and maintains equivalent functional performance. Physical dimensions differ (square 0.375" x 0.375" versus rectangular 0.323" x 0.276"), which may affect PCB layout compatibility but does not alter electrical substitutability.

Parameter Comparison

Engineering Selection Recommendations

Both the CT-6ES103 and 72XR10KLF are Active status components with full RoHS3 compliance and REACH unaffected certification. Selection between these parts should be based on:

• PCB layout constraints: The CT-6ES103 occupies a smaller rectangular footprint (8.20mm x 7.00mm), while the 72XR10KLF requires a larger square footprint (9.53mm x 9.53mm).
• Inventory availability: The 72XR10KLF currently maintains higher stock levels (3693 pcs) compared to the CT-6ES103 (612 pcs).
• Electrical performance is functionally equivalent across all specified parameters.

Frequently Asked Questions (FAQ)

Q: Can the 72XR10KLF directly replace the CT-6ES103 in my circuit?

A: Yes, from an electrical standpoint. Both components share identical resistance, power rating, tolerance, temperature coefficient, and adjustment characteristics. Physical dimensions differ, requiring PCB layout verification.

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

A: The CT-6ES103 has a rectangular face (8.20mm x 7.00mm), while the 72XR10KLF has a square face (9.53mm x 9.53mm). This affects PCB footprint requirements and mounting hole spacing. Verify that your PCB layout accommodates the substitute part's larger dimensions before implementation.

Q: Are both parts compliant with environmental regulations?

A: Yes. Both the CT-6ES103 and 72XR10KLF are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What does the ±100ppm/°C temperature coefficient mean for substitution?

A: Both parts maintain identical temperature stability characteristics. This parameter does not differentiate substitutability between these components.

Q: Is the 1-turn adjustment specification critical for substitution?

A: Yes. The single-turn specification is a core functional parameter. Any substitute must maintain 1-turn adjustment to ensure equivalent operational characteristics and adjustment resolution.
