CT-6EN102 Trimmer Potentiometer Equivalent & Substitute Parts

Part Overview

The CT-6EN102 is a 1 kOhm, 0.5W through-hole trimmer potentiometer manufactured by Nidec Components Corporation. This cermet-based component features side adjustment with PC pin termination and is designed for applications requiring precision variable resistance in compact form factors. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility requirements are met within the same product category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CT-6EN102 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

• Resistance value: 1 kOhms (exact match required)
• Power rating: 0.5W / 1/2W (exact match required)
• Tolerance: ±10% (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Number of turns: 1 (exact match required)
• Adjustment type: Side Adjustment (exact match required)
• Resistive material: Cermet (exact match required)
• Mounting type: Through Hole (exact match required)
• Termination style: PC Pins (exact match required)
• Regulatory compliance: ROHS3 Compliant (minimum requirement)

The 72XR1KLF from TT Electronics/BI meets all electrical and functional specifications. Physical dimensions vary between the main part and substitute, which may affect board layout considerations but does not impact electrical performance or substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

Both the CT-6EN102 and 72XR1KLF are active production components with ROHS3 compliance and equivalent electrical characteristics. Selection between these parts should be based on:

• Board layout constraints: The CT-6EN102 features a rectangular footprint (8.20mm x 7.00mm), while the 72XR1KLF has a larger square footprint (9.53mm x 9.53mm). Verify available PCB space before selection.
• Inventory availability: The 72XR1KLF currently has higher stock levels (2606 pcs vs. 965 pcs for CT-6EN102).
• Supply chain continuity: Both manufacturers maintain active production status, supporting long-term component availability.
• Regulatory requirements: Both parts satisfy ROHS3 and REACH compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the 72XR1KLF directly replace the CT-6EN102 in existing designs?

A: Electrical substitution is valid. The 72XR1KLF matches all electrical specifications (1 kOhm, 0.5W, ±10% tolerance, ±100ppm/°C, 1 turn, side adjustment, cermet, through-hole, PC pins). Physical dimensions differ; verify PCB layout accommodates the larger square footprint (9.53mm x 9.53mm vs. 8.20mm x 7.00mm).

Q: Are there any compliance differences between these parts?

A: Both parts are ROHS3 compliant and REACH unaffected. No compliance barriers exist for substitution.

Q: What is the significance of the different face dimensions?

A: Face dimensions affect PCB footprint and mounting clearance. The CT-6EN102 rectangular design (8.20mm x 7.00mm) occupies less board space than the 72XR1KLF square design (9.53mm x 9.53mm). Mechanical fit must be verified during design review.

Q: Are the adjustment mechanisms identical?

A: Both parts feature side adjustment with 1 turn, providing equivalent operational characteristics for trimmer potentiometer applications.

Q: What is the moisture sensitivity rating difference?

A: The CT-6EN102 has MSL 1 (unlimited), while the 72XR1KLF is not applicable. This does not affect substitution eligibility for standard storage and handling conditions.
