Key Parameters

Substitute Part Grouping Explanation

The CT-6EN103 and its identified substitute (72XR10KLF) share identical electrical specifications and functional characteristics that define substitution eligibility:

• Resistance Value: Both rated at 10 kOhms
• Power Dissipation: Both rated at 0.5W (1/2W)
• Tolerance: Both maintain ±10% tolerance
• Temperature Coefficient: Both specified at ±100ppm/°C
• Adjustment Mechanism: Both feature 1-turn side adjustment
• Resistive Element: Both utilize cermet construction
• Mounting Configuration: Both are through-hole mounted with PC pin termination
• Regulatory Compliance: Both are ROHS3 compliant and REACH unaffected

Physical dimensions differ between the two parts (CT-6EN103: 8.20mm x 7.00mm rectangular; 72XR10KLF: 9.53mm x 9.53mm square), requiring verification of PCB layout constraints during substitution.

Parameter Comparison

Engineering Selection Recommendations

Both the CT-6EN103 and 72XR10KLF maintain active product status with full ROHS3 compliance and REACH unaffected certification, ensuring regulatory alignment for current and future applications. Selection between these parts should be based on:

1. PCB Layout Constraints: The CT-6EN103 occupies a smaller rectangular footprint (8.20mm x 7.00mm) compared to the 72XR10KLF square footprint (9.53mm x 9.53mm). Verify available board space before substitution.

2. Inventory Availability: The 72XR10KLF offers significantly higher stock availability (3,693 units) versus the CT-6EN103 (867 units), relevant for high-volume production or extended lead-time scenarios.

3. Electrical Equivalence: All critical electrical parameters are identical, confirming functional interchangeability within circuit design specifications.

4. Supply Chain Considerations: Both parts are manufactured by established suppliers (Nidec Components Corporation and TT Electronics / BI Technologies) with active product status.

Frequently Asked Questions (FAQ)

Q: Can the 72XR10KLF directly replace the CT-6EN103 in existing designs?

A: Electrical substitution is valid due to identical resistance, power rating, tolerance, temperature coefficient, and adjustment characteristics. Physical substitution requires verification that the larger square footprint (9.53mm x 9.53mm) accommodates existing PCB layout constraints designed for the rectangular 8.20mm x 7.00mm form factor.

Q: Are there any performance differences between these two trimmer potentiometers?

A: No performance differences exist within the specified electrical parameters. Both components utilize cermet resistive elements, maintain identical tolerance and temperature coefficient specifications, and feature 1-turn side adjustment mechanisms.

Q: What compliance certifications apply to both parts?

A: Both the CT-6EN103 and 72XR10KLF are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for industrial and commercial applications.

Q: Which part should be selected for new designs?

A: Selection depends on PCB layout requirements and supply chain priorities. The CT-6EN103 is preferred for space-constrained applications due to its smaller footprint. The 72XR10KLF is preferred for applications where higher inventory availability and extended lead-time mitigation are priorities.

Q: Are the PC pin terminations compatible between both parts?

A: Yes. Both components feature identical PC pin termination styles suitable for through-hole PCB mounting, ensuring mechanical and electrical compatibility at the connection interface.
