CT-6EV104 Trimmer Potentiometer - Equivalent & Substitute Parts

Part Overview

The CT-6EV104 is a 100 kOhm, 0.5W through-hole trimmer potentiometer manufactured by Nidec Components Corporation. This cermet-based component features top adjustment via PC pins and is designed for applications requiring precision variable resistance in compact form factors. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical specifications and mechanical compatibility requirements are met within the same product category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CT-6EV104 are qualified based on matching the following critical parameters: 100 kOhm resistance value, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, single-turn adjustment, top adjustment mechanism, cermet resistive material, through-hole mounting, and PC pin termination. All identified substitutes maintain these electrical and functional specifications. Physical dimensions and packaging formats may vary while preserving electrical equivalence and circuit board compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three components—CT-6EV104, 3329P-1-104LF, and 72PMR100KLF—are Active products with full RoHS3 compliance and equivalent electrical specifications. Selection between these parts should be based on packaging requirements and supply chain availability. The CT-6EV104 and 72PMR100KLF are supplied in Bulk packaging, while the 3329P-1-104LF is supplied in Tube packaging. Physical form factor differences (square 7.00mm, round 6.35mm, and square 9.53mm respectively) may influence board layout considerations. REACH compliance status differs: the 3329P-1-104LF is REACH Affected, while CT-6EV104 and 72PMR100KLF are REACH Unaffected. All parts share identical ECCN (EAR99) and HTSUS (8533.40.8050) classifications.

Frequently Asked Questions (FAQ)

Q: Can the 3329P-1-104LF replace the CT-6EV104 in existing designs?

A: Yes. Both parts meet identical electrical specifications (100 kOhm, 0.5W, ±10% tolerance, ±100ppm/°C). The primary difference is physical form factor: the 3329P-1-104LF has a round 6.35mm diameter body versus the CT-6EV104's square 7.00mm face. Board layout and mounting hole spacing must accommodate this dimensional change.

Q: What is the difference between the 72PMR100KLF and CT-6EV104?

A: Electrical specifications are identical. The 72PMR100KLF has a larger square form factor (9.53mm x 9.53mm) compared to the CT-6EV104 (7.00mm x 7.00mm). Both use PC pin termination and are suitable for through-hole mounting. The larger footprint may require design verification for space-constrained applications.

Q: Are all substitutes RoHS3 compliant?

A: Yes. The CT-6EV104, 3329P-1-104LF, and 72PMR100KLF are all RoHS3 compliant. However, REACH status varies: the 3329P-1-104LF is REACH Affected, while the other two are REACH Unaffected. Verify REACH requirements for your specific application and region.

Q: What packaging formats are available?

A: CT-6EV104 and 72PMR100KLF are supplied in Bulk packaging. The 3329P-1-104LF is supplied in Tube packaging. Packaging selection may affect handling, storage, and assembly processes.

Q: Do all parts have the same moisture sensitivity rating?

A: No. The CT-6EV104 has MSL 1 (Unlimited). The 3329P-1-104LF and 72PMR100KLF have MSL Not Applicable. This difference does not affect electrical equivalence but may influence storage and handling protocols.
