CT-94Y-202 Equivalent & Substitute Parts

Part Overview

The CT-94Y-202 is a 2 kOhm, 0.5W through-hole trimmer potentiometer with cermet resistive material, 18-turn top adjustment, and PC pin termination manufactured by Vishay Beyschlag/Draloric/BC Components. This part is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements. The rectangular form factor (9.60mm x 4.80mm) and PC pin configuration are standard for this component class, enabling direct functional replacement with active alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CT-94Y-202 is determined by strict equivalence across the following critical parameters: resistance value (2 kOhms), power rating (0.5W), tolerance (±10%), temperature coefficient (±100ppm/°C), adjustment type (top adjustment), resistive material (cermet), mounting type (through hole), and termination style (PC pins). The face dimensions must remain within the specified rectangular envelope to ensure PCB layout compatibility.

The CT-94EY202 qualifies as a direct substitute, maintaining all critical electrical and mechanical parameters while offering active product status and improved compliance. The 3296Y-1-202 functions as an alternative substitute with compatible electrical specifications but differs in turn count (25 turns versus 18 turns) and dimensional tolerance, requiring engineering evaluation for specific applications where adjustment resolution is critical.

Parameter Comparison

Engineering Selection Recommendations

The CT-94EY202 is the primary substitute for the obsolete CT-94Y-202. Both parts maintain identical electrical specifications and physical dimensions, with the CT-94EY202 offering the advantage of active product status and RoHS3 compliance. This part is suitable for new designs and production environments requiring regulatory compliance.

The 3296Y-1-202 serves as an alternative substitute when the CT-94EY202 is unavailable. This part maintains all critical electrical parameters but incorporates 25 turns instead of 18 turns, resulting in finer adjustment resolution. The dimensional variance (9.53mm x 4.83mm versus 9.60mm x 4.80mm) is within typical PCB layout tolerances for through-hole components. Selection of this alternative requires confirmation that the increased turn count does not conflict with application-specific adjustment requirements or mechanical constraints.

Frequently Asked Questions (FAQ)

Q: Can the CT-94EY202 be used as a direct replacement for the CT-94Y-202?

A: Yes. The CT-94EY202 maintains identical electrical specifications (2 kOhms, 0.5W, ±10% tolerance, ±100ppm/°C), identical physical dimensions (9.60mm x 4.80mm), and identical turn count (18 turns). Both parts use cermet resistive material, top adjustment, through-hole mounting, and PC pin termination. The primary advantage is active product status and RoHS3 compliance.

Q: What is the difference between the CT-94EY202 and the 3296Y-1-202?

A: Both parts share identical electrical specifications and mounting characteristics. The primary difference is turn count: the CT-94EY202 has 18 turns while the 3296Y-1-202 has 25 turns. The increased turn count in the 3296Y-1-202 provides finer adjustment resolution. Dimensional differences are minimal (9.60mm x 4.80mm versus 9.53mm x 4.83mm) and typically accommodated within standard PCB layout tolerances.

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

A: The CT-94Y-202 is RoHS non-compliant. The CT-94EY202 is RoHS3 compliant, making it suitable for applications requiring regulatory compliance. The 3296Y-1-202 is RoHS non-compliant. For new designs subject to RoHS requirements, the CT-94EY202 is the appropriate selection.

Q: Will the 3296Y-1-202 fit in the same PCB footprint as the CT-94Y-202?

A: The dimensional difference between the parts is minimal (0.378" x 0.189" versus 0.375" x 0.190"). Standard PCB layout tolerances for through-hole components typically accommodate this variance. However, applications with tight mechanical constraints should verify footprint compatibility before implementation.

Q: What inventory status should influence part selection?

A: The CT-94EY202 has 2054 units in stock, the 3296Y-1-202 has 1098 units in stock, and the CT-94Y-202 has 821 units in stock. For new production, the CT-94EY202 is recommended based on active product status and superior availability. The 3296Y-1-202 serves as a secondary option when the primary substitute is unavailable.
