CT-6ER201 Equivalent & Substitute Parts

Part Overview

The CT-6ER201 is a 200 Ohm, 0.5W trimmer potentiometer manufactured by Nidec Components Corporation. This through-hole component features cermet resistive material, PC pin termination, and top adjustment capability in a square form factor (7.00mm x 7.00mm). The part is Active status and ROHS3 compliant, making it suitable for applications requiring precision variable resistance in compact assemblies. Equivalent parts are identified when electrical specifications and functional characteristics align within the allowed parameter tolerances for this product category.

Key Parameters

Substitute Part Grouping Explanation

The 82PR200LF qualifies as an equivalent substitute based on the following critical parameters:

• Resistance value matches exactly at 200 Ohms
• Power rating is identical at 0.5W (1/2W)
• Tolerance specification is ±10% for both parts
• Temperature coefficient is ±100ppm/°C for both parts
• Number of turns is 1 for both parts
• Adjustment type is top adjustment for both parts
• Resistive material is cermet for both parts
• Mounting type is through hole for both parts
• Termination style is PC pins for both parts
• Both parts are ROHS3 compliant and REACH unaffected

The primary difference is the form factor: CT-6ER201 uses a square package (7.00mm x 7.00mm), while 82PR200LF uses a round package (6.35mm diameter). This dimensional variation does not affect electrical performance but requires PCB layout verification for mechanical fit.

Parameter Comparison

Engineering Selection Recommendations

Both CT-6ER201 and 82PR200LF are Active status components with full ROHS3 compliance and REACH unaffected status, making them suitable for current production applications. Selection between these parts should be based on PCB layout constraints and available inventory. The CT-6ER201 offers 1087 units in stock, while the 82PR200LF provides 1602 units. The round package of the 82PR200LF occupies a smaller footprint (6.35mm diameter) compared to the square package of the CT-6ER201 (7.00mm x 7.00mm), which may influence board space optimization. Both parts carry identical electrical specifications and regulatory compliance, ensuring functional interchangeability within the specified parameter tolerances.

Frequently Asked Questions (FAQ)

Q: Can the 82PR200LF directly replace the CT-6ER201 in existing designs?

A: Yes, from an electrical standpoint. Both parts share identical resistance, power rating, tolerance, temperature coefficient, and adjustment characteristics. However, the different package geometries (square vs. round) require PCB layout verification to confirm mechanical fit within the existing footprint.

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

A: The main difference is the physical package form factor. The CT-6ER201 uses a square body (7.00mm x 7.00mm), while the 82PR200LF uses a round body (6.35mm diameter). All electrical parameters are identical.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both the CT-6ER201 and 82PR200LF are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components.

Q: Does the cermet resistive material affect substitution compatibility?

A: No. Both parts use cermet material, which is a key parameter for this substitution group. Cermet provides stable resistance characteristics and temperature performance across both components.

Q: Which part should be selected based on availability?

A: The 82PR200LF currently has higher inventory (1602 units) compared to the CT-6ER201 (1087 units). If supply chain considerations are primary, the 82PR200LF offers greater availability. Otherwise, selection should be based on PCB layout requirements.
