CT6P205 Trimmer Potentiometer - Equivalent & Substitute Parts

Part Overview

The CT6P205 is a 2 MOhm, 0.5W through-hole trimmer potentiometer manufactured by Vishay Beyschlag/Draloric/BC Components. This cermet-based component features top adjustment with PC pin termination and is designed for applications requiring precision variable resistance in a compact square form factor (7.00mm x 7.00mm).

The CT6P205 is classified as obsolete. Locating equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production, repair, and field replacement applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CT6P205 are qualified based on electrical and mechanical parameter equivalence. The following parameters must match or remain within acceptable tolerances for direct substitution:

• Resistance value: 2 MOhms
• Power rating: 0.5W (1/2W)
• Tolerance: ±10%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 1 Turn
• Adjustment type: Top Adjustment
• Resistive material: Cermet
• Mounting type: Through Hole
• Termination style: PC Pins
• Form factor: Square or rectangular configuration within 7.00mm nominal dimension

Two substitute parts meet these criteria and are available as active products with current manufacturing status.

Parameter Comparison

Engineering Selection Recommendations

CT-6EP205 (Nidec Components Corporation) is the primary substitute for the obsolete CT6P205. This part maintains identical electrical specifications and physical form factor while offering active product status and RoHS3 compliance. The CT-6EP205 is available in bulk packaging with substantial inventory (4580 units), supporting both new production and field replacement requirements.

3362P-1-205 (Bourns Inc. Trimpot® 3362 Series) is an alternative substitute that meets all electrical parameter requirements. The 3362P-1-205 features a rectangular form factor (6.99mm x 6.60mm) compared to the square configuration of the main part. This dimensional difference requires PCB layout verification to confirm mechanical compatibility. The 3362P-1-205 is available in tube packaging with active product status. RoHS compliance status differs from the CT-6EP205.

For applications requiring RoHS3 compliance and identical form factor, CT-6EP205 is the recommended selection. For applications where rectangular form factor is acceptable, 3362P-1-205 provides an alternative from an established trimmer potentiometer manufacturer.

Frequently Asked Questions (FAQ)

Q: Can the CT-6EP205 be used as a direct replacement for the CT6P205?

A: Yes. The CT-6EP205 matches all electrical parameters (2 MOhms, 0.5W, ±10% tolerance, ±100ppm/°C temperature coefficient) and maintains the same square form factor (7.00mm x 7.00mm). No circuit redesign is required.

Q: What is the primary difference between the CT-6EP205 and 3362P-1-205?

A: Both parts are electrically equivalent. The primary difference is physical form factor: CT-6EP205 maintains the square 7.00mm x 7.00mm configuration, while 3362P-1-205 uses a rectangular 6.99mm x 6.60mm form factor. PCB layout compatibility must be verified before selecting the 3362P-1-205.

Q: Does the CT-6EP205 require any design changes?

A: No design changes are required. The CT-6EP205 is a direct electrical and mechanical equivalent to the CT6P205, with identical pin configuration, adjustment mechanism, and electrical performance.

Q: What is the significance of RoHS3 compliance on the CT-6EP205?

A: RoHS3 compliance indicates the CT-6EP205 meets current environmental and material restriction standards. If your application or end-market requires RoHS compliance, the CT-6EP205 is the appropriate selection.

Q: Are there packaging differences between the substitute parts?

A: Yes. The CT-6EP205 is supplied in bulk packaging, while the 3362P-1-205 is supplied in tube packaging. Bulk packaging is typically preferred for high-volume production, while tube packaging is suitable for smaller quantities and field replacement stock.

Q: Can both substitute parts be used interchangeably in the same design?

A: Electrical interchangeability is confirmed. Mechanical interchangeability depends on PCB layout. The rectangular form factor of the 3362P-1-205 may not fit mounting pads designed for the square form factor of the CT6P205 or CT-6EP205. Verify PCB pad dimensions before substitution.
