CT-6EV504 Equivalent & Substitute Parts

Part Overview

The CT-6EV504 is a 500 kOhms trimmer potentiometer manufactured by Nidec Components Corporation, rated at 0.5W with PC pin termination for through-hole mounting. This cermet-based trimmer features top adjustment with a 1-turn configuration and is designed for applications requiring precision variable resistance in compact form factors. The part is currently active in production with 1061 units in stock. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility parameters are maintained across alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CT-6EV504 is determined by strict equivalence across the following critical parameters:

• Resistance value: 500 kOhms (exact match required)
• Power rating: 0.5W minimum
• Tolerance: ±10% or better
• Temperature coefficient: ±100ppm/°C or better
• Number of turns: 1-turn configuration
• Adjustment type: Top adjustment
• Resistive material: Cermet
• Mounting type: Through hole
• Termination style: PC pins
• Regulatory compliance: ROHS3 compliant

The 72PR500KLF from TT Electronics/BI meets all electrical and functional requirements for direct substitution. Physical dimensions differ slightly but do not affect electrical performance or circuit board layout compatibility for standard through-hole applications.

Parameter Comparison

Engineering Selection Recommendations

Both the CT-6EV504 and 72PR500KLF are active production components with full ROHS3 compliance and REACH unaffected status, making either suitable for new designs and existing applications. Selection between these parts should be based on:

• PCB layout constraints: The CT-6EV504 occupies a smaller footprint (7.00mm square) compared to the 72PR500KLF (9.53mm square)
• Supply chain availability: The 72PR500KLF currently has higher inventory (1969 units) versus 1061 units for the CT-6EV504
• Manufacturer preference: Both manufacturers maintain active production status with equivalent electrical performance

All electrical parameters, regulatory certifications, and functional specifications are identical between the two parts.

Frequently Asked Questions (FAQ)

Q: Can the 72PR500KLF directly replace the CT-6EV504 in existing designs?

A: Yes. All electrical specifications, power ratings, tolerance, temperature coefficient, and termination styles are identical. The primary difference is physical size (9.53mm versus 7.00mm square face). Verify PCB layout accommodates the larger footprint before substitution.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and classified under the same ECCN (EAR99) and HTSUS code (8533.40.8050).

Q: What determines if a trimmer potentiometer can substitute for the CT-6EV504?

A: Substitutes must match the following parameters: 500 kOhms resistance, 0.5W power rating, ±10% tolerance, ±100ppm/°C temperature coefficient, 1-turn configuration, top adjustment, cermet material, through-hole mounting, and PC pin termination.

Q: Does the size difference affect electrical performance?

A: No. Physical dimensions do not affect electrical characteristics. Size differences only impact PCB layout compatibility and mounting footprint.

Q: Are both parts suitable for new product designs?

A: Yes. Both the CT-6EV504 and 72PR500KLF are active production components with no end-of-life notices, making them appropriate for new designs requiring 500 kOhms trimmer potentiometers with the specified electrical and mechanical parameters.
