CT6R504 Equivalent & Substitute Parts Reference

Part Overview

The CT6R504 is a 500 kOhms, 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 product is currently obsolete, making equivalent substitutes necessary for ongoing maintenance, repair, and legacy system support where original stock is depleted.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CT6R504 is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must match or be compatible:

• Resistance value: 500 kOhms (exact match required)
• Power rating: 0.5W minimum
• Tolerance: ±10% or better
• Temperature coefficient: ±100ppm/°C or better
• Number of turns: 1 Turn
• Adjustment type: Top Adjustment
• Resistive material: Cermet
• Mounting type: Through Hole
• Termination style: PC Pins
• Package footprint: Compatible with 7.00mm x 7.00mm mounting area

Two substitute parts meet these criteria: CT-6ER504 (Nidec Components Corporation) and 3362R-1-504 (Bourns Inc.). Both maintain electrical equivalence and mechanical compatibility with the original CT6R504 design.

Parameter Comparison

Engineering Selection Recommendations

CT-6ER504 (Nidec Components Corporation) is the primary substitute for the CT6R504. This part maintains identical electrical specifications and package dimensions while offering active product status and RoHS3 compliance. The CT-6ER504 is available in bulk packaging with 3304 units in stock, providing supply continuity for production and repair applications.

3362R-1-504 (Bourns Inc.) serves as an alternative substitute with equivalent electrical performance. The Trimpot® 3362 series maintains all critical electrical parameters and through-hole PC pin termination. Package dimensions are nominally equivalent (6.99mm x 6.60mm versus 7.00mm x 7.00mm), suitable for standard PCB layouts. This part is available in tube packaging with 660 units in stock. Note that REACH status is affected, requiring compliance verification for applications subject to REACH regulations.

Selection between CT-6ER504 and 3362R-1-504 depends on supply availability, packaging requirements, and regulatory compliance needs of the end application.

Frequently Asked Questions (FAQ)

Q: Can CT-6ER504 be used as a direct replacement for CT6R504?

A: Yes. The CT-6ER504 maintains identical electrical specifications (500 kOhms, 0.5W, ±10% tolerance, ±100ppm/°C) and mechanical compatibility (through-hole PC pins, 7.00mm x 7.00mm package). Both parts are functionally equivalent for circuit operation.

Q: What is the difference between CT-6ER504 and 3362R-1-504?

A: Both parts are electrically equivalent with identical resistance, power rating, tolerance, and temperature coefficient. The primary differences are manufacturer (Nidec versus Bourns), package dimensions (7.00mm square versus 6.99mm x 6.60mm rectangular), RoHS compliance status (RoHS3 compliant versus non-compliant), and REACH status (unaffected versus affected). Mechanical compatibility is maintained for standard PCB layouts.

Q: Why is the original CT6R504 obsolete?

A: The CT6R504 is classified as obsolete by the manufacturer. Active substitutes (CT-6ER504 and 3362R-1-504) are available to support legacy system maintenance and repair.

Q: Are there packaging differences between the substitutes?

A: CT-6ER504 is supplied in bulk packaging, while 3362R-1-504 is supplied in tube packaging. Both are suitable for through-hole PCB assembly. Package dimensions are nominally equivalent and compatible with standard 7.00mm x 7.00mm mounting footprints.

Q: What compliance certifications apply to each substitute?

A: CT-6ER504 is RoHS3 compliant and REACH unaffected. 3362R-1-504 is RoHS non-compliant and REACH affected. Compliance requirements should be verified against application-specific regulatory standards before final selection.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, for applications where the original CT6R504 was specified. All three parts share identical electrical parameters and through-hole PC pin termination. Mechanical compatibility is maintained across standard PCB layouts. Compliance certifications should be reviewed for regulatory requirements.
