CT9P103 Equivalent & Substitute Parts Reference

Part Overview

The Vishay Beyschlag/Draloric/BC Components CT9P103 is a through-hole, cermet trimmer potentiometer with a resistance of 10 kOhms, 0.5W (1/2W) power rating, 18 turns, and side adjustment. It features PC pin termination and a rectangular form factor. With the product status listed as obsolete, identifying functional substitute trimmer potentiometers is essential to support ongoing manufacturing, repairs, and inventory continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute trimmer potentiometer models for CT9P103 are identified strictly by matching the following key parameters: resistance value (10 kOhms), power rating (0.5W, 1/2W), tolerance (±10%), temperature coefficient (±100ppm/°C), number of turns (18 or more), side adjustment, cermet resistive material, through hole mounting, and PC pins termination style. Only models matching all these parameters are considered functionally substitutable.

Parameter Comparison

Engineering Selection Recommendations

When selecting substitutes for the obsolete CT9P103, review product status for long-term availability. CT-9EP103 from Nidec Components Corporation is active, matches all functional parameters, and is ROHS3 compliant. 3296P-1-103 from Bourns Inc. is active, matches all functional parameters, and shares similar form and fit. Only use parts that explicitly list the required certifications and environmental compliance as needed for the application.

Frequently Asked Questions (FAQ)

Q1: What are the essential parameters for substituting the CT9P103 trimmer potentiometer?
A1: Key substitution parameters are resistance (10 kOhms), power (0.5W, 1/2W), tolerance (±10%), temperature coefficient (±100ppm/°C), number of turns (18 or more), adjustment type (side adjustment), resistive element material (cermet), through-hole mounting, and PC pins termination.

Q2: Do the substitute parts match the mechanical size of the CT9P103?
A2: Substitute parts match the essential mounting and mechanical features; slight variations exist in body dimensions and shape but maintain the same mounting type and pinout style.

Q3: Are the substitute parts RoHS compliant?
A3: The CT-9EP103 from Nidec Components Corporation is ROHS3 compliant. The 3296P-1-103 from Bourns Inc. and the original CT9P103 are both RoHS non-compliant.

Q4: Does the number of turns affect substitutability?
A4: All substitutes provide 18 or more turns, matching or exceeding the original specification for adjustment precision within the provided parameter set.

Q5: Are inventory and lifecycle status considered for substitution?
A5: Substitute parts are active and available in inventory while CT9P103 is obsolete. Selection for ongoing production should consider active lifecycle status.
