CT6R102 Trimmer Potentiometer - Equivalent & Substitute Parts

Part Overview

The CT6R102 is a 1 kOhm, 0.5W through-hole trimmer potentiometer manufactured by Vishay Beyschlag/Draloric/BC Components. This cermet-based adjustment component features top-mounted access and PC pin termination, designed for applications requiring precision variable resistance in compact form factors. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CT6R102 are qualified based on matching the following critical parameters:

• Resistance value: 1 kOhms
• Power rating: 0.5W (1/2W)
• Tolerance: ±10%
• Temperature coefficient: ±100ppm/°C
• Number of turns: 1
• Adjustment type: Top Adjustment
• Resistive material: Cermet
• Mounting type: Through Hole
• Termination style: PC Pins
• Face dimensions: Approximately 0.276" x 0.276" (7.00mm x 7.00mm)

All identified substitutes meet these electrical and mechanical specifications, ensuring functional compatibility in applications originally designed for the CT6R102.

Parameter Comparison

Engineering Selection Recommendations

CT-6ER102 (Nidec Components Corporation) is the primary substitute for the obsolete CT6R102. This part maintains identical electrical specifications and physical dimensions while offering active product status and ROHS3 compliance. The CT-6ER102 is available in bulk packaging with 1049 units in stock.

3362R-1-102 (Bourns Inc.) serves as an alternative substitute with all matching electrical parameters. Minor dimensional variation exists in the face geometry (0.275" x 0.260" versus 0.276" x 0.276"), which remains within acceptable tolerance for through-hole mounting applications. This part is supplied in tube packaging with 1093 units in stock and maintains active product status. Note that the 3362R-1-102 is RoHS non-compliant and REACH-affected, requiring evaluation against specific application compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the CT-6ER102 directly replace the CT6R102 in existing designs?

A: Yes. The CT-6ER102 matches all critical electrical parameters (1 kOhm resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient) and maintains identical physical dimensions and termination style. The primary difference is product status (active versus obsolete) and improved RoHS3 compliance.

Q: What is the significance of the dimensional difference between the CT-6ER102 and 3362R-1-102?

A: The CT-6ER102 maintains the original square 0.276" x 0.276" face dimension. The 3362R-1-102 has a rectangular face of 0.275" x 0.260". Both dimensions accommodate standard through-hole PCB layouts with 7.00mm spacing. The dimensional variation is negligible for most applications but should be verified against specific PCB footprint requirements.

Q: Are there compliance considerations when substituting the CT6R102?

A: The CT6R102 is RoHS non-compliant. The CT-6ER102 offers ROHS3 compliance, making it suitable for applications with RoHS requirements. The 3362R-1-102 remains RoHS non-compliant and is REACH-affected. Application compliance mandates should guide selection between these alternatives.

Q: What packaging formats are available for these substitutes?

A: The CT-6ER102 is supplied in bulk packaging. The 3362R-1-102 is supplied in tube packaging. Packaging selection depends on procurement volume and handling requirements for your specific application.

Q: Are all three parts functionally interchangeable in circuit operation?

A: Yes. All three parts share identical electrical specifications: 1 kOhm resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 1-turn adjustment, cermet resistive material, and top-mounted adjustment access. Functional interchangeability is confirmed for circuit-level operation.
