Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PSU85015A is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Capacitance value (850 µF), voltage rating (125 V), and tolerance band (0%, +20%) must be identical. Polarization type (Bi-Polar) must match exactly.

Mechanical Specifications: Package type (Radial, Can - QC Terminals), mounting configuration (Chassis Mount), and terminal style must be identical to ensure physical and electrical compatibility in the circuit.

Environmental & Compliance: Operating temperature range (-40°C ~ 65°C), RoHS3 compliance status, and Moisture Sensitivity Level (MSL 1) must be maintained.

Application Compatibility: Motor start application designation confirms functional suitability.

Substitute parts must originate from the same manufacturer series (PSU) and maintain active product status to ensure supply chain reliability and consistent performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The PSU85015 serves as a direct electrical equivalent to the PSU85015A, with all critical electrical and environmental parameters matching exactly. Both components are manufactured by Cornell Dubilier Electronics within the PSU series and maintain active product status with full ROHS3 compliance.

The primary distinction between these parts is the seated height specification: PSU85015A measures 3.375" (85.73mm) maximum, while PSU85015 measures 4.375" (111.13mm) maximum. This dimensional difference must be evaluated against available mounting space and circuit board layout constraints in the target application.

Selection between PSU85015A and PSU85015 is determined by physical space availability within the chassis or enclosure. Both parts deliver identical electrical performance for motor start applications across the specified operating temperature range. Compliance certifications, including RoHS3 status and REACH unaffected designation, are equivalent across both options.

Frequently Asked Questions (FAQ)

Q: Can PSU85015 replace PSU85015A in all applications?

A: PSU85015 is electrically equivalent to PSU85015A across all specified parameters. However, the increased seated height (4.375" versus 3.375") requires verification of available mounting space. If vertical clearance is constrained, PSU85015A is the appropriate selection.

Q: Are the electrical performance characteristics identical between PSU85015A and PSU85015?

A: Yes. Both components share identical capacitance (850 µF), voltage rating (125 V), tolerance (0%, +20%), polarization (Bi-Polar), operating temperature range (-40°C ~ 65°C), and application designation (Motor Start).

Q: Do both parts meet the same compliance requirements?

A: Yes. PSU85015A and PSU85015 are both ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (Unlimited). Both maintain active product status from Cornell Dubilier Electronics.

Q: What is the significance of the QC terminal designation?

A: QC terminals refer to the quick-connect terminal style integrated into the radial can package. This terminal configuration is identical on both PSU85015A and PSU85015, ensuring mechanical and electrical compatibility with existing circuit connections.

Q: How does the diameter specification affect substitution?

A: Both PSU85015A and PSU85015 share an identical diameter of 1.813" (46.05mm). Diameter equivalence ensures compatibility with standard mounting fixtures and chassis cutouts designed for this capacitor family.

Q: Are there inventory considerations when selecting between these parts?

A: PSU85015A maintains 764 pieces in stock, while PSU85015 maintains 721 pieces in stock. Both are available as new original components in bulk packaging. Selection should account for immediate availability requirements and project lead times.
