CT-94P-202 Equivalent & Substitute Parts

Part Overview

The CT-94P-202 is a 2 kOhm, 0.5W through-hole trimmer potentiometer manufactured by Vishay Beyschlag/Draloric/BC Components. This cermet-based side-adjustment trimmer features 18 turns and PC pin termination in a rectangular form factor. The part is currently obsolete, necessitating identification of equivalent alternatives that maintain functional compatibility while meeting current procurement and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CT-94P-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 (side adjustment), resistive material (cermet), mounting type (through hole), and termination style (PC pins).

The identified substitutes maintain these core electrical and mechanical specifications. Variations in the number of turns (18 vs. 25) and physical dimensions represent acceptable design differences within the same functional category, as they do not affect the primary electrical performance or circuit compatibility when used in applications tolerant of these parameters.

Parameter Comparison

Engineering Selection Recommendations

The CT-94EP202 (Nidec Components Corporation) is the primary direct substitute. It maintains identical electrical specifications and turn count while offering active product status and ROHS3 compliance. The physical form factor differs slightly (square vs. rectangular face), but both maintain equivalent footprint compatibility for standard through-hole PC pin applications.

The 3296P-1-202 (Bourns Inc., Trimpot® 3296 series) serves as an alternative substitute with identical electrical parameters. This part features 25 turns instead of 18, providing finer adjustment resolution. It is actively manufactured and available in higher inventory quantities. The rectangular form factor closely matches the original CT-94P-202 dimensions. Note that this part carries non-compliant RoHS status and REACH-affected designation.

Selection between CT-94EP202 and 3296P-1-202 should be based on compliance requirements and adjustment resolution needs specific to the application.

Frequently Asked Questions (FAQ)

Q: Can CT-94EP202 be used as a direct replacement for CT-94P-202?

A: Yes. The CT-94EP202 maintains identical electrical specifications (2 kOhms, 0.5W, ±10% tolerance, ±100ppm/°C temperature coefficient) and identical turn count (18 turns). Both feature side adjustment, cermet resistive material, through-hole mounting, and PC pin termination. The primary difference is the square vs. rectangular face dimension and active product status with ROHS3 compliance.

Q: What is the significance of the 25-turn variant (3296P-1-202) compared to the 18-turn original?

A: The 25-turn configuration provides finer adjustment granularity, allowing more precise resistance tuning per mechanical rotation. This does not affect electrical performance or circuit compatibility but may impact adjustment procedure and user experience in applications requiring frequent calibration.

Q: Are there physical compatibility concerns when substituting these parts?

A: All three parts feature through-hole PC pin termination and similar rectangular/square form factors within the 9.5–9.6mm width range and 4.8–4.83mm depth range. Standard PCB layouts designed for the CT-94P-202 will accommodate both substitute parts without modification.

Q: What compliance differences exist between the substitutes?

A: CT-94EP202 is ROHS3 compliant and REACH unaffected. The 3296P-1-202 is RoHS non-compliant and REACH affected. Selection should align with end-product compliance requirements and regional regulations.

Q: Can these parts be used interchangeably in all applications?

A: Electrical interchangeability is confirmed across all three parts for applications tolerant of the specified parameters. Physical form factor and compliance status may impose constraints in specific applications. Verify PCB layout compatibility and regulatory requirements before final selection.
