Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CT-6ETV203 is determined by strict equivalence across the following critical parameters: resistance value (20 kOhms), power rating (0.5W), tolerance (±10%), temperature coefficient (±100ppm/°C), number of turns (1), adjustment type (top adjustment), resistive material (cermet), mounting type (through hole), and termination style (PC pins). All identified substitute parts match these core electrical and mechanical specifications. Physical dimensions vary within acceptable tolerances for through-hole mounting applications. Packaging format differences (tape & box versus tube) do not affect functional equivalence. Regulatory compliance status is documented for each part to support procurement decisions in regulated environments.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts are active production components with full regulatory compliance. The CT-6ETV203, 25PR20KLF, 3329H-1-203LF, T73YE203KT20, and T73YP203KT20 are functionally equivalent for applications requiring 20 kOhm 0.5W cermet trimmer potentiometers with top adjustment and PC pin termination.

For applications subject to RoHS3 compliance requirements, the CT-6ETV203, 3329H-1-203LF, T73YE203KT20, and T73YP203KT20 meet this specification. The 25PR20KLF carries standard RoHS compliance.

For applications with REACH compliance requirements, the T73YE203KT20 and T73YP203KT20 are REACH Unaffected. The CT-6ETV203 is also REACH Unaffected. The 3329H-1-203LF is REACH Affected, and the 25PR20KLF is REACH Unaffected.

Physical dimensions vary: the CT-6ETV203 and T73YE203KT20 and T73YP203KT20 feature rectangular faces (7.00mm x 6.60mm or 7.00mm x 7.00mm), the 25PR20KLF has a square face (6.86mm x 6.86mm), and the 3329H-1-203LF has a round form factor (6.35mm diameter). PCB layout and mounting hole spacing should be verified for mechanical fit.

Frequently Asked Questions (FAQ)

Q: Can the 25PR20KLF replace the CT-6ETV203 in all applications? A: The 25PR20KLF is electrically equivalent and functionally interchangeable for standard applications. Physical dimensions differ slightly (6.86mm square versus 7.00mm square), requiring verification of PCB layout compatibility. The 25PR20KLF carries standard RoHS compliance rather than RoHS3; applications with RoHS3 requirements should use alternative substitutes.

Q: What is the difference between the T73YE203KT20 and T73YP203KT20? A: Both parts are electrically and mechanically identical with matching 20 kOhm resistance, 0.5W power rating, and rectangular form factor (7.00mm x 6.60mm). Both are ROHS3 compliant and REACH Unaffected. Selection between these Vishay Sfernice parts depends on packaging availability and procurement lead times.

Q: Does the 3329H-1-203LF round form factor affect substitution? A: The 3329H-1-203LF is electrically equivalent but features a round 6.35mm diameter body compared to the square or rectangular forms of other substitutes. PCB mounting hole patterns and layout spacing must be verified before selection. This part is ROHS3 compliant but REACH Affected.

Q: Are packaging differences (tube versus tape & box) significant for substitution? A: Packaging format does not affect electrical or mechanical performance. The CT-6ETV203 is supplied in tape & box format, while substitute parts are supplied in tube packaging. Packaging selection depends on assembly process requirements and inventory management practices.

Q: Which substitute part has the highest inventory availability? A: The 3329H-1-203LF (Bourns) has 6800 pieces in stock, followed by the 25PR20KLF (TT Electronics/BI) with 2646 pieces. The CT-6ETV203 has 667 pieces available. Inventory levels should be confirmed with suppliers for current availability.
