CT-6EV102 Trimmer Potentiometer: Equivalent & Substitute Parts

Part Overview

The CT-6EV102 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 square form factor (7.00mm x 7.00mm). The part is active in production status with ROHS3 compliance and unlimited moisture sensitivity rating. Equivalent and substitute parts are identified for applications requiring alternative sourcing, packaging formats, or form factors while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CT-6EV102 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. Form factor variations (square versus round) and dimensional differences are noted but do not preclude functional substitution. Packaging format differences (bulk versus tube) reflect inventory and procurement considerations rather than electrical incompatibility.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active production status and meet the core electrical specifications of the CT-6EV102. Selection between alternatives depends on specific application constraints:

For applications with strict PCB layout requirements matching the original 7.00mm x 7.00mm square form factor, the CT-6EV102 or T73YE102KT20 are direct geometric equivalents. The T73YE102KT20 offers tube packaging and ROHS3 compliance with identical electrical performance.

For applications accommodating compact form factors, the 25PR1KLF, 3329H-1-102LF, and 82PR1KLF provide reduced footprints (6.35mm to 6.86mm) while maintaining all electrical parameters. The 3329H-1-102LF is sealed and offers Bourns Trimpot® series reliability.

For applications requiring larger form factors, the 72PMR1KLF and 72PR1KLF provide 9.53mm x 9.53mm square packages with bulk packaging availability and ROHS3 compliance.

All substitute parts carry ROHS3 or equivalent RoHS compliance. The CT-6EV102 and 72PMR1KLF/72PR1KLF/82PR1KLF/T73YE102KT20 are ROHS3 compliant. The 25PR1KLF carries standard RoHS compliance. The 3329H-1-102LF is ROHS3 compliant with REACH affected status.

Frequently Asked Questions (FAQ)

Q: Can the 3329H-1-102LF substitute for the CT-6EV102 in a square footprint application?

A: The 3329H-1-102LF has a round form factor (6.35mm diameter) compared to the CT-6EV102 square form factor (7.00mm x 7.00mm). Electrical substitution is valid, but PCB layout accommodation is required.

Q: What is the difference between bulk and tube packaging?

A: Packaging format does not affect electrical or mechanical performance. Bulk packaging (CT-6EV102, 72PMR1KLF, 72PR1KLF, 82PR1KLF) suits high-volume assembly. Tube packaging (25PR1KLF, 3329H-1-102LF, T73YE102KT20) accommodates lower-volume or component-level procurement.

Q: Are all substitutes RoHS compliant?

A: Yes. The CT-6EV102, 3329H-1-102LF, 72PMR1KLF, 72PR1KLF, 82PR1KLF, and T73YE102KT20 are ROHS3 compliant. The 25PR1KLF carries standard RoHS compliance.

Q: Does form factor affect electrical performance?

A: No. Square, round, and rectangular form factors do not alter resistance, power rating, tolerance, temperature coefficient, or adjustment characteristics. Form factor selection is driven by PCB layout constraints only.

Q: Can I use the 72PMR1KLF or 72PR1KLF in place of the CT-6EV102?

A: Electrical substitution is valid. The 72PMR1KLF and 72PR1KLF have larger form factors (9.53mm x 9.53mm square) and require PCB layout verification for clearance and mounting compatibility.

Q: What is the inventory status of substitute parts?

A: All substitute parts are listed as new original stock. Inventory quantities range from 1,900 to 12,299 units across manufacturers and distributors.
