CT-6ETH102 Equivalent & Substitute Parts

Part Overview

The CT-6ETH102 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 electrical specifications, mechanical compatibility, and regulatory compliance align with the original design requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CT-6ETH102 is determined by strict alignment of the following critical parameters:

• 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 differ (square 0.375" x 0.375" versus rectangular 0.323" x 0.276"), which may affect PCB layout compatibility but does not alter electrical performance or functional operation.

Parameter Comparison

Engineering Selection Recommendations

The 72XR1KLF qualifies as a direct electrical and functional substitute for the CT-6ETH102. Both components are active products with ROHS3 compliance and identical electrical specifications across all critical parameters including resistance, power rating, tolerance, temperature coefficient, and adjustment characteristics.

Selection between these parts should be based on:

• PCB layout constraints: The CT-6ETH102 occupies a smaller rectangular footprint (8.20mm x 7.00mm) compared to the 72XR1KLF square footprint (9.53mm x 9.53mm). Verify available board space before substitution.
• Supply chain availability: The 72XR1KLF currently has higher inventory (2606 pcs) versus CT-6ETH102 (951 pcs).
• Packaging requirements: CT-6ETH102 is supplied in Tape & Box format; 72XR1KLF is supplied in Bulk packaging.

Both parts carry identical regulatory compliance status (ROHS3, REACH Unaffected, EAR99 classification).

Frequently Asked Questions (FAQ)

Q: Can the 72XR1KLF replace the CT-6ETH102 in my circuit?

A: Yes, from an electrical standpoint. Both components have identical resistance (1 kOhm), power rating (0.5W), tolerance (±10%), temperature coefficient (±100ppm/°C), and adjustment characteristics. Verify that the larger physical dimensions of the 72XR1KLF (0.375" x 0.375" square versus 0.323" x 0.276" rectangular) fit your PCB layout.

Q: Are there any compliance differences between these parts?

A: No. Both the CT-6ETH102 and 72XR1KLF are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.

Q: What is the main difference between these two parts?

A: The primary differences are physical dimensions and packaging format. The CT-6ETH102 has a smaller rectangular footprint and comes in Tape & Box packaging, while the 72XR1KLF has a larger square footprint and is supplied in Bulk packaging. Electrical performance is identical.

Q: Does the different face dimension affect performance?

A: No. The face dimension difference does not affect electrical performance, resistance accuracy, power handling, or temperature stability. The difference is purely mechanical and affects only PCB layout compatibility.

Q: Can I use these parts interchangeably in production?

A: Electrical interchangeability is confirmed. However, production changeover requires PCB layout verification to ensure the 72XR1KLF dimensions are compatible with your board design. Packaging format differences may also affect assembly line processes.
