Key Parameters

Substitute Part Grouping Explanation

Substitute identification for the CT-6EP200 is based on the following critical parameters that must align for functional equivalence:

• Electrical Specifications: Resistance value, power rating, and tolerance determine circuit compatibility
• Mechanical Interface: Mounting type (through hole), termination style (PC pins), and physical dimensions affect PCB integration
• Adjustment Characteristics: Single-turn top adjustment mechanism ensures operational consistency
• Material Composition: Cermet resistive element provides stability and performance characteristics
• Regulatory Compliance: RoHS3 and REACH status ensure environmental and supply chain compatibility

The substitute part 82PR200LF shares core electrical and mechanical attributes with the CT-6EP200, including matching power rating, tolerance, adjustment type, resistive material, mounting method, and termination style. Both components maintain equivalent regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

Selection between CT-6EP200 and 82PR200LF requires evaluation of circuit-specific requirements:

CT-6EP200 (Nidec Components Corporation) is the primary specification. This component is recommended when the 20 Ohm resistance value is a circuit requirement and the square form factor (7.00mm x 7.00mm) accommodates PCB layout constraints. The unlimited MSL rating (MSL 1) provides flexibility for storage and handling in standard warehouse environments.

82PR200LF (TT Electronics / BI Technologies) presents a different resistance value (200 Ohms) and physical geometry (round, 6.35mm diameter). This part is not a direct electrical substitute for the CT-6EP200 due to the 10:1 resistance ratio difference. However, it shares identical power rating, tolerance, adjustment mechanism, and resistive material composition. The superior temperature coefficient (±100ppm/°C versus ±250ppm/°C) may provide performance advantages in temperature-sensitive applications if the 200 Ohm value is acceptable for the circuit design.

Both components maintain Active product status and full RoHS3 compliance, ensuring regulatory alignment and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can 82PR200LF directly replace CT-6EP200 in my circuit?

A: Direct replacement is not recommended without circuit redesign. The 82PR200LF has a 200 Ohm resistance value compared to the CT-6EP200's 20 Ohm specification. This 10:1 difference will alter circuit behavior. Substitution is only valid if your application can accommodate 200 Ohm resistance and the circuit has been re-evaluated for this value.

Q: What are the key matching parameters between these parts?

A: Both components share identical power rating (0.5W), tolerance (±10%), number of turns (1), adjustment type (top adjustment), resistive material (cermet), mounting type (through hole), termination style (PC pins), and RoHS3 compliance status. These parameters ensure mechanical and regulatory compatibility when resistance value is not a limiting factor.

Q: How do the physical dimensions differ?

A: The CT-6EP200 has a square form factor measuring 0.276" x 0.276" (7.00mm x 7.00mm). The 82PR200LF uses a round form factor with 0.250" diameter (6.35mm). These dimensional differences may affect PCB footprint compatibility and layout considerations.

Q: What is the significance of the temperature coefficient difference?

A: The CT-6EP200 has a temperature coefficient of ±250ppm/°C, while the 82PR200LF specifies ±100ppm/°C. The 82PR200LF exhibits superior temperature stability, meaning its resistance value changes less across temperature variations. This may be advantageous in precision applications, provided the 200 Ohm resistance value is acceptable.

Q: Are both parts RoHS3 compliant?

A: Yes, both CT-6EP200 and 82PR200LF maintain full RoHS3 compliance and REACH Unaffected status, ensuring environmental and regulatory alignment for procurement and deployment.

Q: What does MSL 1 rating mean for the CT-6EP200?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life and storage flexibility. The component does not require special moisture control during storage or handling, simplifying inventory management compared to higher MSL-rated components.
