Equivalent & Substitute Parts Reference for CT9X103

Part Overview

CT9X103 is a trimmer potentiometer manufactured by Vishay Beyschlag/Draloric/BC Components, featuring a resistance of 10 kOhms, 0.5W (1/2W) power rating, and side adjustment through hole mounting. The component is constructed with cermet resistive material and terminated via PC pins. The part is obsolete, necessitating the identification of substitutes for ongoing designs and maintenance. Alternative models must strictly match key electrical, mechanical, and compliance parameters.

Key Parameters

Substitute Part Grouping Explanation

The substitution logic for CT9X103 is based strictly on the following permitted parameters: resistance value (10 kOhms), power rating (0.5W, 1/2W), tolerance (±10%), temperature coefficient (±100ppm/°C), adjustment type (side adjustment), resistive material (cermet), mounting type (through hole), termination style (PC pins), and physical face dimensions. Substitute models listed conform to these requirements or specify the differences where applicable.

Parameter Comparison

Engineering Selection Recommendations

Selection between substitute trimmer potentiometers should be performed with strict attention to product status and compliance certifications. CT9X103 is obsolete; both CT-9EX103 and 3296X-1-103 are active. CT-9EX103 is ROHS3 compliant and REACH unaffected, while 3296X-1-103 matches CT9X103 in compliance status (RoHS non-compliant) but is REACH affected. Physical dimensions for CT-9EX103 match the original, while 3296X-1-103 differs slightly. Selection should be based on matching compliance certifications and inventory considerations as listed.

Frequently Asked Questions (FAQ)

Q: What are the key parameters for substituting CT9X103 in trimmer potentiometer applications?
A: The permitted substitution parameters are: resistance (10 kOhms), power rating (0.5W, 1/2W), tolerance (±10%), temperature coefficient (±100ppm/°C), number of turns, adjustment type (side adjustment), resistive material (cermet), mounting type (through hole), termination style (PC pins), and face dimensions.

Q: Are the substitute models physically compatible for direct replacement?
A: CT-9EX103 has identical face dimensions to CT9X103. 3296X-1-103 has a slight variation in face size.

Q: How do compliance statuses affect substitute selection?
A: CT-9EX103 is ROHS3 compliant; 3296X-1-103 and CT9X103 are RoHS non-compliant. Compliance selection should be based on system or regulatory requirements.

Q: Can substitutes be used in the same PCB footprint?
A: All listed models use through hole mounting and PC pin termination. CT-9EX103 shares the same face dimensions as CT9X103. 3296X-1-103 has a marginally different face size.

Q: Are there differences in adjustment or electrical performance?
A: All models feature side adjustment and cermet resistive material. Number of turns varies: CT9X103 and CT-9EX103 have 18 (or 18.0) turns; 3296X-1-103 has 25 turns. All meet the core electrical parameters defined in the input.
