CT6W202 Trimmer Potentiometer - Equivalent & Substitute Parts

Part Overview

The CT6W202 is a 2 kOhm, 0.5W through-hole trimmer potentiometer manufactured by Vishay Beyschlag/Draloric/BC Components. This cermet-based adjustment component features PC pin termination and top-adjustment design in a compact square form factor. The product is currently obsolete, making equivalent substitutes necessary for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CT6W202 is determined by strict equivalence across all critical electrical and mechanical parameters. The following criteria establish valid substitutes:

• Resistance value: 2 kOhms (exact match required)
• Power rating: 0.5W minimum
• Tolerance: ±10% or better
• Temperature coefficient: ±100ppm/°C or better
• Number of turns: 1 Turn (exact match)
• Adjustment type: Top Adjustment (exact match)
• Resistive material: Cermet (exact match)
• Mounting type: Through Hole (exact match)
• Termination style: PC Pins (exact match)
• Form factor: Square or rectangular within 0.275" to 0.276" width and 0.260" to 0.276" height

Two substitute parts meet these criteria: CT-6EW202 (Nidec Components Corporation) and 3362H-1-202 (Bourns Inc.).

Parameter Comparison

Engineering Selection Recommendations

Both CT-6EW202 and 3362H-1-202 are electrically and mechanically equivalent to the CT6W202 across all critical parameters. Selection between these substitutes should be based on the following factors:

CT-6EW202 (Nidec Components Corporation): This substitute maintains identical electrical specifications and form factor to the original CT6W202. The part is currently in active production status with 1907 units in stock. It achieves RoHS3 compliance, making it suitable for applications requiring modern environmental standards. REACH status remains unaffected. Packaging is supplied in bulk format.

3362H-1-202 (Bourns Inc.): This substitute meets all electrical requirements and maintains the 1-turn, top-adjustment cermet design. The part is active in production with 744 units available. Form factor is rectangular (0.275" x 0.260") rather than square, representing a minor dimensional variation within acceptable tolerance. RoHS compliance status is non-compliant, matching the original part. REACH status is affected. Packaging is supplied in tube format. This part belongs to the Trimpot® 3362 sealed series.

For new designs or systems requiring RoHS3 compliance, CT-6EW202 is the preferred selection. For legacy system replacement where RoHS compliance is not a requirement, either substitute is acceptable based on availability and packaging preference.

Frequently Asked Questions (FAQ)

Q: Can CT-6EW202 and 3362H-1-202 be used interchangeably with CT6W202?

A: Yes. Both substitutes match the CT6W202 across all critical electrical parameters: 2 kOhm resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 1-turn adjustment, top-adjustment design, cermet resistive material, through-hole mounting, and PC pin termination. The 3362H-1-202 has a minor rectangular form factor (0.275" x 0.260") compared to the square form factor of the original (0.276" x 0.276"), but remains within acceptable dimensional tolerance for standard PCB layouts.

Q: What is the difference in RoHS compliance between the substitutes?

A: CT-6EW202 is RoHS3 compliant, while 3362H-1-202 is RoHS non-compliant, matching the original CT6W202. RoHS3 compliance indicates the part meets current Restriction of Hazardous Substances directives. Selection depends on whether your application or regulatory requirements mandate RoHS compliance.

Q: Are there packaging differences between the substitutes?

A: Yes. CT-6EW202 is supplied in bulk packaging, while 3362H-1-202 is supplied in tube packaging. Bulk packaging is suitable for high-volume assembly operations, while tube packaging is typical for component storage and manual assembly environments.

Q: Does the rectangular form factor of 3362H-1-202 affect PCB compatibility?

A: The 3362H-1-202 rectangular form factor (0.275" x 0.260") is dimensionally similar to the original square form factor (0.276" x 0.276"). For standard PCB layouts with through-hole mounting, this minor variation typically does not affect compatibility. However, verify footprint spacing in your specific PCB design if space constraints are critical.

Q: What is the REACH status difference, and does it matter?

A: CT-6EW202 has REACH Unaffected status, while 3362H-1-202 has REACH Affected status. REACH Affected indicates the part contains substances of concern under the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) regulation. Selection depends on whether your application or supply chain requires REACH compliance.

Q: Why is the original CT6W202 obsolete?

A: The CT6W202 is listed as obsolete, indicating it is no longer in active production. This is common for legacy trimmer potentiometer designs as manufacturers consolidate product lines and transition to newer alternatives. Active substitutes ensure continued availability for maintenance and repair of existing systems.
