CT-6EV202 Equivalent & Substitute Parts Reference

Part Overview

The CT-6EV202 is a 2 kOhm 0.5W through-hole trimmer potentiometer manufactured by Nidec Components Corporation. This cermet-based trimmer features PC pin termination with top adjustment capability and is classified as an active product. Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or inventory limitations. The CT-6EV202 maintains ROHS3 compliance and is suitable for applications requiring precision resistive adjustment in compact form factors.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CT-6EV202 is determined by strict equivalence across the following critical parameters:

• Resistance value: 2 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: Top 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)

All three substitute parts listed (3329H-1-202LF, 72PR2KLF, 82PR2KLF) meet these electrical and mechanical equivalence criteria. Physical form factor variations (square vs. round body geometry) do not affect functional substitution when PCB layout accommodates the alternative dimensions.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and ROHS3 compliance, confirming their suitability for applications requiring regulatory adherence. Selection between the CT-6EV202 and its equivalents should be based on:

• Availability and lead time requirements
• PCB layout constraints related to body geometry (square vs. round form factors)
• Packaging format preference (bulk vs. tube)
• Supply chain qualification and inventory levels

The 3329H-1-202LF (Bourns Trimpot® 3329 series) and 82PR2KLF (TT Electronics round body) offer the smallest footprint at 6.35mm diameter. The 72PR2KLF (TT Electronics square body) provides a larger 9.53mm x 9.53mm face. The CT-6EV202 occupies an intermediate footprint at 7.00mm x 7.00mm square geometry.

Frequently Asked Questions (FAQ)

Q: Can the 3329H-1-202LF replace the CT-6EV202 directly on the PCB?

A: Electrical substitution is complete. Physical substitution requires PCB layout verification. The 3329H-1-202LF uses a round 6.35mm diameter body versus the CT-6EV202's square 7.00mm x 7.00mm geometry. Mounting hole patterns and clearance zones must be confirmed before implementation.

Q: What is the difference between the 72PR2KLF and 82PR2KLF?

A: Both parts are electrically identical 2 kOhm 0.5W cermet trimmers with PC pin termination. The primary difference is body geometry: the 72PR2KLF features a square 9.53mm x 9.53mm face, while the 82PR2KLF uses a round 6.35mm diameter body. Electrical performance and adjustment characteristics are equivalent.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The CT-6EV202, 3329H-1-202LF, 72PR2KLF, and 82PR2KLF all carry ROHS3 compliance certification, confirming suitability for applications with restricted substance requirements.

Q: Does packaging format affect component performance?

A: No. The CT-6EV202 is supplied in bulk packaging, while the 3329H-1-202LF is supplied in tube packaging. Packaging format does not alter electrical characteristics, performance, or reliability. Selection should reflect procurement and handling requirements.

Q: Can I use the 72PR2KLF if my PCB has limited space?

A: The 72PR2KLF occupies the largest footprint at 9.53mm x 9.53mm square geometry. If space is constrained, the 3329H-1-202LF or 82PR2KLF (both 6.35mm diameter) or the CT-6EV202 (7.00mm x 7.00mm) would be more suitable alternatives.
