CT6R502 Equivalent & Substitute Parts Reference

Part Overview

The CT6R502 is a 5 kOhm, 0.5W through-hole trimmer potentiometer manufactured by Vishay Beyschlag/Draloric/BC Components. This cermet-based trimmer features top adjustment with PC pin termination and is housed in a square 7.00mm x 7.00mm package. The part is currently obsolete, making equivalent substitutes necessary for ongoing production, maintenance, and repair applications where this component specification is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CT6R502 are qualified based on matching the following critical parameters:

• Resistance value: 5 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
• Package footprint compatibility: Square or rectangular format within 7.00mm nominal dimensions

Parts meeting these electrical and mechanical specifications are functionally equivalent for circuit applications requiring this trimmer potentiometer classification.

Parameter Comparison

Engineering Selection Recommendations

The CT-6ER502 (Nidec Components Corporation) is the primary substitute for the obsolete CT6R502. This part maintains identical electrical specifications and package dimensions while offering active product status and RoHS3 compliance, making it suitable for new designs and production environments with regulatory requirements.

The 3362R-1-502 (Bourns Inc., Trimpot® 3362 series) is a secondary equivalent option. While it matches all critical electrical parameters and maintains through-hole PC pin termination, its rectangular package dimensions (6.99mm x 6.60mm) differ slightly from the original square format. This part is active and available but carries non-RoHS compliance status. Mechanical fit verification is required before board-level substitution.

Frequently Asked Questions (FAQ)

Q: Can CT-6ER502 directly replace CT6R502 in existing designs?

A: Yes. The CT-6ER502 matches all electrical specifications (5 kOhm, 0.5W, ±10% tolerance, ±100ppm/°C) and maintains identical package dimensions (7.00mm square). No circuit modifications are required.

Q: What is the difference between the Nidec and Bourns substitutes?

A: Both parts meet electrical requirements. The primary difference is package geometry: CT-6ER502 maintains the original square 7.00mm format, while 3362R-1-502 uses a rectangular 6.99mm x 6.60mm footprint. Verify PCB layout compatibility before selecting the Bourns option.

Q: Are there RoHS compliance considerations?

A: The CT6R502 original part is RoHS non-compliant. The CT-6ER502 substitute is RoHS3 compliant, making it preferable for applications subject to RoHS regulations. The 3362R-1-502 remains non-compliant.

Q: Do all substitutes have the same moisture sensitivity rating?

A: The CT-6ER502 maintains MSL 1 (Unlimited) matching the original. The 3362R-1-502 lists MSL as Not Applicable. For moisture-sensitive assembly environments, the Nidec part is the preferred choice.

Q: Can I use 3362R-1-502 if space is constrained?

A: The 3362R-1-502 has a slightly smaller rectangular footprint (6.99mm x 6.60mm) compared to the square 7.00mm original. Verify that your PCB layout accommodates this geometry before substitution.
