CT-6EV502 Equivalent & Substitute Parts

Part Overview

The CT-6EV502 is a 5 kOhm 0.5W through-hole trimmer potentiometer manufactured by Nidec Components Corporation. This cermet-based trimmer features PC pin termination, top adjustment, and a square form factor (7.00mm x 7.00mm). The part is active in production status and maintains full RoHS3 compliance. Equivalent and substitute parts are identified when applications require alternative sourcing due to inventory constraints, lead time considerations, or design flexibility within the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CT-6EV502 is determined by strict equivalence across the following critical parameters: resistance value (5 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 requirements. Physical form factor variations (square versus round) and packaging differences (bulk versus tube) do not affect functional substitution within circuit applications where PCB layout accommodates the alternative dimensions.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active production status and full ROHS3 compliance, ensuring regulatory alignment with the CT-6EV502. The 3329H-1-502LF (Bourns Trimpot® 3329 series) and 82PR5KLF (TT Electronics 82 series) feature identical round form factors at 6.35mm diameter, minimizing PCB layout modifications. The 72PR5KLF (TT Electronics 72 series) provides a larger square footprint at 9.53mm x 9.53mm, suitable for applications with expanded board space. The T73YE502KT20 (Vishay Sfernice T73 series) offers a rectangular profile closely matching the original CT-6EV502 dimensions. Selection should prioritize form factor compatibility with existing PCB designs and lead time availability from the preferred supplier.

Frequently Asked Questions (FAQ)

Q: Can the 3329H-1-502LF substitute for the CT-6EV502 in all applications? A: Yes, the 3329H-1-502LF meets all electrical specifications (5 kOhms, 0.5W, ±10% tolerance, ±100ppm/°C). The round 6.35mm form factor differs from the square 7.00mm original, requiring verification that PCB hole spacing and layout accommodate the alternative geometry.

Q: What is the primary difference between the 72PR5KLF and 82PR5KLF? A: Both parts are manufactured by TT Electronics/BI with identical electrical specifications. The 72PR5KLF features a square form factor (9.53mm x 9.53mm), while the 82PR5KLF uses a round form factor (6.35mm diameter). Selection depends on available PCB space and mounting hole configuration.

Q: Are all substitute parts RoHS3 compliant? A: Yes, all listed substitute parts carry ROHS3 compliance certification, matching the regulatory status of the CT-6EV502.

Q: Does packaging format (bulk versus tube) affect electrical performance? A: No, packaging format does not affect electrical or mechanical performance. Bulk and tube packaging represent different distribution methods for the same component specifications.

Q: Which substitute offers the closest physical match to the CT-6EV502? A: The T73YE502KT20 (Vishay Sfernice) provides the closest dimensional match with a rectangular form factor of 7.00mm x 6.60mm, compared to the original 7.00mm x 7.00mm square profile.
