CT6P103 Trimmer Potentiometer - Equivalent & Substitute Parts

Part Overview

The CT6P103 is a 10 kOhm, 0.5W through-hole trimmer potentiometer manufactured by Vishay Beyschlag/Draloric/BC Components. This single-turn, top-adjustment cermet trimmer features PC pin termination and a square form factor of 7.00mm x 7.00mm. The part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts must maintain identical electrical specifications and mechanical compatibility to ensure direct replacement without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CT6P103 is determined by strict equivalence across the following parameters:

• Resistance value: 10 kOhms (exact match required)
• Power rating: 0.5W minimum
• Tolerance: ±10% or better
• Temperature coefficient: ±100ppm/°C or better
• Number of turns: 1 Turn (single-turn operation)
• Adjustment type: Top Adjustment
• Resistive material: Cermet
• Mounting type: Through Hole
• Termination style: PC Pins
• Face dimension: Approximately 7.00mm x 7.00mm (minor dimensional variations acceptable within mechanical envelope)

Two substitute parts meet these criteria: CT-6EP103 (Nidec Components Corporation) and 3362P-1-103 (Bourns Inc.). Both maintain full electrical and mechanical compatibility with the original CT6P103 specification.

Parameter Comparison

Engineering Selection Recommendations

CT-6EP103 (Nidec Components Corporation) is the primary substitute for the obsolete CT6P103. This part maintains identical electrical specifications and mechanical form factor while offering active product status and RoHS3 compliance. The CT-6EP103 is available in bulk packaging with substantial inventory (25,780 pcs), ensuring supply continuity for production applications.

3362P-1-103 (Bourns Inc.) serves as an alternative substitute. While electrically equivalent, this part exhibits minor dimensional differences (6.99mm x 6.60mm rectangular face versus 7.00mm x 7.00mm square face). The 3362P-1-103 remains in active production with adequate inventory (10,110 pcs) and is available in tube packaging. However, this part is RoHS non-compliant and REACH-affected, requiring compliance evaluation for specific applications.

For new designs and production requiring regulatory compliance, CT-6EP103 is the preferred selection. For legacy system maintenance where compliance is not a constraint, either substitute provides functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can CT-6EP103 replace CT6P103 in existing circuits without modification?

A: Yes. The CT-6EP103 maintains identical electrical parameters (10 kOhms, 0.5W, ±10% tolerance, ±100ppm/°C temperature coefficient) and mechanical compatibility (through-hole PC pins, top adjustment, 7.00mm x 7.00mm form factor). Direct substitution is possible without circuit redesign.

Q: What is the difference between CT-6EP103 and 3362P-1-103?

A: Both parts are electrically equivalent. The primary differences are: (1) face dimension—CT-6EP103 maintains the original square 7.00mm x 7.00mm form factor, while 3362P-1-103 is rectangular (6.99mm x 6.60mm); (2) regulatory compliance—CT-6EP103 is RoHS3 compliant, while 3362P-1-103 is not; (3) packaging—CT-6EP103 is supplied in bulk, 3362P-1-103 in tubes.

Q: Why is the CT6P103 marked as obsolete?

A: The CT6P103 is no longer manufactured by Vishay Beyschlag/Draloric/BC Components. Active substitutes (CT-6EP103 and 3362P-1-103) are available from alternative manufacturers to support ongoing applications.

Q: Are there any compliance considerations when selecting a substitute?

A: Yes. CT-6EP103 is RoHS3 compliant and REACH unaffected, suitable for applications with regulatory requirements. The 3362P-1-103 is RoHS non-compliant and REACH-affected. Compliance requirements should be evaluated based on end-use application and regional regulations.

Q: Will the rectangular form factor of 3362P-1-103 affect PCB layout?

A: The dimensional difference (6.99mm x 6.60mm rectangular versus 7.00mm x 7.00mm square) is minor. Mechanical fit depends on PCB footprint design. Verify that the through-hole spacing and mounting envelope accommodate the 3362P-1-103 geometry before implementation.

Q: What inventory levels are available for each substitute?

A: CT-6EP103 has 25,780 pcs in stock. 3362P-1-103 has 10,110 pcs in stock. Both provide adequate supply for production applications.
