Equivalent & Substitute Parts Reference for CT-94Y-103

Part Overview

Manufacturer part number CT-94Y-103, produced by Vishay Beyschlag/Draloric/BC Components, is a through-hole cermet trimmer potentiometer rated at 10 kOhms with 0.5W (1/2W) power handling. The part offers 18 turns, top adjustment, ±10% tolerance, and features PC pin termination. This part is part of the CT94 series and is now classified as obsolete. As a result, it is necessary to find equivalent substitutes to ensure form, fit, and function continuity for maintenance and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for CT-94Y-103 are chosen exclusively based on the following matched parameters: resistance value, power rating, tolerance, temperature coefficient, number of turns, adjustment type, resistive material, mounting type, termination style, and size/dimension. Substitutions within the potentiometer/trimmer category must align precisely with these parameters to maintain functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Select substitute part number CT-94EY103 from Nidec Components Corporation or 3296Y-1-103 from Bourns Inc. based on inventory availability, product lifecycle status, and regulatory compliance. CT-94EY103 is RoHS3 compliant and active, while 3296Y-1-103 and the original CT-94Y-103 are not RoHS compliant. All listed substitutes fulfill the functional key parameters as indicated in the table above.

Frequently Asked Questions (FAQ)

Q: What key parameters must match for a trimmer potentiometer substitute?
A: Resistance, power rating, tolerance, temperature coefficient, number of turns, adjustment type, resistive material, mounting type, termination style, and size/dimension.

Q: Does the number of turns affect substitutability?
A: Substitution is allowed when the number of turns is within the same range and the adjustment method remains the same, as per the matched substitute part data.

Q: Are size and mounting style critical for substitution?
A: Size/dimension, mounting type, and termination style must match to ensure physical compatibility with the existing design.

Q: How do RoHS and REACH compliance impact substitute selection?
A: When regulatory compliance (e.g., RoHS, REACH) is a requirement, choose substitutes that match or exceed the main part’s status as indicated in the comparison table.

Q: Is packaging relevant for the substitution process?
A: Packaging is not a specified substitution criterion within the provided data. All substitute options utilize through hole/PC pin style unless otherwise indicated in the key parameters.
