CT6X104 Trimmer Potentiometer - Equivalent & Substitute Parts

Part Overview

The CT6X104 is a 100 kOhms, 0.5W through-hole trimmer potentiometer manufactured by Vishay Beyschlag/Draloric/BC Components. This cermet-based side-adjustment trimmer features PC pin termination and is designed for applications requiring precision resistance tuning in compact rectangular form factors.

The CT6X104 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CT6X104 are identified based on strict electrical and mechanical parameter matching:

Critical Matching Parameters:

• Resistance value: 100 kOhms
• Power rating: 0.5W (1/2W)
• Tolerance: ±10%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 1
• Adjustment type: Side Adjustment
• Resistive material: Cermet
• Mounting type: Through Hole
• Termination style: PC Pins

All identified substitutes meet these core electrical specifications. Dimensional variations and compliance certifications are noted but do not disqualify substitution eligibility when electrical parameters align.

Parameter Comparison

Engineering Selection Recommendations

CT-6EX104 (Nidec Components Corporation) is the direct functional equivalent. This part maintains identical electrical specifications and physical dimensions to the CT6X104. The CT-6EX104 is currently in active production status with 3,104 units in stock. This substitute is ROHS3 compliant, providing environmental regulatory alignment for new designs or updated production runs.

3362W-1-104 (Bourns Inc.) is a manufacturer-recommended alternative. All electrical parameters match the CT6X104 specification. The Bourns Trimpot® 3362 series is actively produced and widely available (879 units in stock). Physical dimensions are slightly smaller (0.275" x 0.260" versus 0.323" x 0.276"), which may require PCB layout verification for existing designs. This part is non-RoHS compliant and REACH affected.

Selection between these substitutes depends on design constraints: choose CT-6EX104 for dimensional compatibility and RoHS compliance; choose 3362W-1-104 when space constraints permit the smaller footprint and legacy compliance status is acceptable.

Frequently Asked Questions (FAQ)

Q: Can CT-6EX104 and 3362W-1-104 be used interchangeably with CT6X104?

A: Both parts meet all electrical specifications (100 kOhms, 0.5W, ±10% tolerance, ±100ppm/°C temperature coefficient, 1-turn side adjustment, cermet resistive material, through-hole PC pin termination). CT-6EX104 maintains identical dimensions. The 3362W-1-104 has a smaller footprint and requires PCB layout verification.

Q: What is the primary reason the CT6X104 has been discontinued?

A: The CT6X104 is classified as obsolete. Active production alternatives from Nidec and Bourns provide equivalent electrical performance with improved availability and, in the case of CT-6EX104, enhanced regulatory compliance.

Q: Are there compliance differences between the substitutes?

A: CT-6EX104 is ROHS3 compliant with unlimited moisture sensitivity rating. The 3362W-1-104 is RoHS non-compliant and REACH affected. Both are EAR99 classified. Compliance requirements should guide selection for new designs or regulated applications.

Q: Does the smaller size of the 3362W-1-104 affect electrical performance?

A: No. Electrical specifications remain identical. The dimensional difference (0.275" x 0.260" versus 0.323" x 0.276") is a physical characteristic only. PCB layout compatibility must be confirmed before substitution in existing designs.

Q: What inventory levels are available for each substitute?

A: CT-6EX104 has 3,104 units in stock. 3362W-1-104 has 879 units in stock. Both are actively produced and available for procurement.
