Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict matching of core electrical and mechanical parameters. All substitute parts listed maintain identical resistance value (10 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). Physical form factor variations (square vs. round) and packaging differences (bulk vs. tube) are noted but do not preclude substitution when PCB layout and assembly processes accommodate the dimensional change. All substitute parts maintain active product status and regulatory compliance (ROHS3 or equivalent, REACH unaffected).

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain full electrical equivalence to the CT-6EV103 across resistance, power rating, tolerance, temperature coefficient, and adjustment characteristics. Selection among substitutes is determined by form factor compatibility with PCB layout and assembly process constraints.

Square form factor substitutes (25PR10KLF, 72PMR10KLF, 72PR10KLFTB) accommodate designs with space constraints similar to the original CT-6EV103 square geometry. The 25PR10KLF provides the closest dimensional match at 6.86mm x 6.86mm. The 72-series parts (72PMR10KLF, 72PR10KLFTB) feature a larger 9.53mm x 9.53mm footprint suitable for designs with expanded PCB real estate.

Round form factor substitutes (3329H-1-103LF, 3329P-1-103LF, 82MR10KLF, 82PR10KLF, 82PR10KLFTB) provide 6.35mm diameter geometry and are applicable where circular mounting patterns are preferred or where existing PCB layouts accommodate round component placement.

Rectangular form factor substitutes (T73YE103KT20, T73YP103KT20) maintain dimensions closely aligned to the original part (7.00mm x 6.60mm) and represent direct geometric alternatives.

All substitute parts carry ROHS3 compliance or equivalent RoHS certification and maintain REACH unaffected status, ensuring regulatory alignment with the original CT-6EV103 specification.

Frequently Asked Questions (FAQ)

Q: Can I substitute the CT-6EV103 with any of the listed parts without circuit redesign?

A: Yes, all listed parts are electrically equivalent. Substitution requires only verification that the physical form factor (square, round, or rectangular) and dimensions fit the PCB layout and assembly equipment. No circuit redesign is necessary.

Q: What is the primary difference between substitute parts?

A: The primary differences are physical form factor and packaging. All parts maintain identical electrical specifications (10 kOhms, 0.5W, ±10% tolerance, ±100ppm/°C temperature coefficient, 1 turn, top adjustment, cermet material, through-hole mounting, PC pins). Form factor options include square (7.00mm, 6.86mm, or 9.53mm), round (6.35mm diameter), or rectangular (7.00mm x 6.60mm) geometries.

Q: Are packaging differences (bulk vs. tube) significant for substitution?

A: Packaging differences affect handling, storage, and assembly logistics but do not impact electrical or mechanical compatibility. Bulk packaging suits high-volume automated assembly, while tube packaging is appropriate for lower-volume or manual assembly processes.

Q: Do all substitute parts meet the same regulatory requirements as the CT-6EV103?

A: Yes. All substitute parts carry ROHS3 compliance or equivalent RoHS certification and maintain REACH unaffected status, matching the regulatory profile of the original CT-6EV103.

Q: Which substitute part provides the closest dimensional match to the CT-6EV103?

A: The T73YE103KT20 and T73YP103KT20 (Vishay Sfernice) provide the closest dimensional match with rectangular geometry of 7.00mm x 6.60mm, compared to the original square geometry of 7.00mm x 7.00mm. The 25PR10KLF (TT Electronics/BI) offers the closest square form factor at 6.86mm x 6.86mm.

Q: Can I use round form factor parts as direct replacements in a design specified for square geometry?

A: Round form factor substitution requires PCB layout verification to confirm that the 6.35mm diameter footprint accommodates the mounting hole pattern and clearance requirements of the original square design. Physical interference or clearance issues must be evaluated before implementation.
