CT-6ETV102 Trimmer Potentiometer: Equivalent & Substitute Parts

Part Overview

The CT-6ETV102 is a 1 kOhm, 0.5W through-hole trimmer potentiometer manufactured by Nidec Components Corporation. This cermet-based component features top adjustment, PC pin termination, and a compact square form factor (7.00mm x 7.00mm). The part is active in production status with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are required for design flexibility, supply chain alternatives, or inventory optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CT-6ETV102 is determined by strict equivalence across the following parameters: resistance value (1 kOhms), power rating (0.5W), tolerance (±10%), temperature coefficient (±100ppm/°C), number of turns (1), adjustment type (top adjustment), resistive material (cermet), mounting type (through hole), and termination style (PC pins). All identified substitute parts meet these core electrical and mechanical criteria. Physical form factor variations (square vs. round) and packaging differences (tape & box, tube, bulk) do not disqualify substitution but must be evaluated for PCB layout compatibility and assembly process requirements.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active production status and meet the electrical specifications of the CT-6ETV102. Selection between alternatives depends on form factor compatibility with PCB layout constraints and packaging requirements for assembly processes. The 25PR1KLF offers the highest inventory availability (12,299 pcs) with RoHS compliance, though it carries standard RoHS rather than ROHS3 designation. The 3329H-1-102LF and 82PR1KLF feature round form factors (6.35mm diameter) suitable for applications where circular footprints are preferred. The 72PMR1KLF and 72PR1KLF present larger square footprints (9.53mm) for designs with less spatial constraints. The T73YE102KT20 maintains dimensional similarity to the CT-6ETV102 with a rectangular profile and ROHS3 compliance. All parts carry REACH Unaffected or REACH Affected status as specified; verify REACH compliance requirements for your application jurisdiction.

Frequently Asked Questions (FAQ)

Q: Can I substitute the CT-6ETV102 with any of these parts without circuit redesign?

A: Electrical substitution is valid across all listed parts due to identical resistance, power rating, tolerance, and temperature coefficient specifications. However, physical form factor differences require PCB layout verification. The CT-6ETV102 uses a square 7.00mm footprint; substitutes with different dimensions (round 6.35mm, square 9.53mm, or rectangular 7.00mm x 6.60mm) may require footprint adjustment.

Q: What is the difference between ROHS3 and RoHS compliance?

A: ROHS3 represents the third iteration of the Restriction of Hazardous Substances directive with updated substance restrictions. Standard RoHS compliance indicates adherence to earlier directive versions. Both certifications confirm lead-free and hazardous substance restrictions; verify your application's specific regulatory requirement.

Q: Does packaging type affect electrical performance?

A: No. Tape & Box (TB), Tube, and Bulk packaging formats do not alter component electrical characteristics. Packaging selection is determined by assembly process requirements and inventory management practices.

Q: Are there form factor constraints I should consider?

A: Yes. Round components (3329H-1-102LF, 82PR1KLF at 6.35mm diameter) occupy different PCB space than square alternatives. Larger square options (72PMR1KLF, 72PR1KLF at 9.53mm) require additional board real estate. Verify your PCB layout accommodates the selected substitute's physical dimensions before procurement.

Q: What does ±100ppm/°C temperature coefficient mean for my application?

A: This specification indicates the resistance value changes by approximately 100 parts per million for each degree Celsius change in operating temperature. All listed substitutes share this specification, ensuring equivalent thermal stability across the operating range.
