CT6P104 Equivalent & Substitute Parts Reference

Part Overview

The CT6P104 is a 100 kOhms trimmer potentiometer manufactured by Vishay Beyschlag/Draloric/BC Components. This through-hole mounted cermet trimmer features 0.5W power rating, ±10% tolerance, and top adjustment capability with PC pin termination. The product is currently obsolete, making identification of equivalent and substitute parts essential for ongoing maintenance, repair, and legacy system support. Active alternatives with identical electrical and mechanical specifications are available from current manufacturers.

Substitute Part Grouping Explanation

Substitute parts for the CT6P104 are qualified based on matching the following critical parameters:

Resistance value: 100 kOhms
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

Engineering Selection Recommendations

CT-6EP104 (Nidec Components Corporation): This substitute maintains identical electrical specifications and square face dimensions matching the original CT6P104. The part is currently in active production status with 31,282 units in stock. CT-6EP104 achieves RoHS3 compliance, providing environmental regulatory advantage over the original obsolete part. MSL rating remains 1 (Unlimited). This part represents the most direct functional replacement.

3362P-1-104 (Bourns Inc.): This substitute meets all electrical requirements and maintains the 1-turn top-adjustment cermet trimmer configuration. The part is active in production with 3,760 units available. Face dimensions are rectangular (0.275" x 0.260" / 6.99mm x 6.60mm) versus the square configuration of the original, requiring PCB layout verification for mechanical fit. The part is RoHS non-compliant but REACH Affected status differs from the original specification. Packaging is supplied in tube format.

Selection between substitutes depends on PCB layout constraints regarding face dimension geometry and regulatory compliance requirements for the end application.

Frequently Asked Questions (FAQ)

Q: Can CT-6EP104 and 3362P-1-104 be used interchangeably with CT6P104?

A: Both parts match the electrical specifications (100 kOhms, 0.5W, ±10% tolerance, ±100ppm/°C, 1-turn cermet trimmer with top adjustment and PC pin termination). CT-6EP104 maintains identical square face dimensions. 3362P-1-104 has rectangular face dimensions (0.275" x 0.260" versus 0.276" x 0.276"), requiring PCB layout verification for mechanical clearance and mounting hole alignment.

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

A: CT-6EP104 is RoHS3 compliant, meeting current environmental directives. The original CT6P104 and 3362P-1-104 are both RoHS non-compliant. Applications subject to RoHS requirements should specify CT-6EP104.

Q: Are there packaging differences between the substitutes?

A: CT-6EP104 is supplied in bulk packaging. 3362P-1-104 is supplied in tube packaging. Both formats are standard for through-hole component distribution and do not affect electrical or mechanical performance.

Q: How do the REACH compliance statuses differ?

A: CT6P104 and CT-6EP104 are REACH Unaffected. 3362P-1-104 is REACH Affected. Applications requiring REACH compliance documentation should specify CT-6EP104 or the original CT6P104.

Q: What is the MSL rating for these parts?

A: All three parts (CT6P104, CT-6EP104, and 3362P-1-104) carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.

Q: Are the electrical tolerances and temperature coefficients identical across all three parts?

A: Yes. All three parts specify ±10% tolerance and ±100ppm/°C temperature coefficient, ensuring equivalent performance in circuit applications.
