PSU5335A Equivalent & Substitute Parts

Part Overview

The PSU5335A is a 53 µF, 250 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in the PSU series. This radial, can-style component with QC terminals is designed for motor start applications and operates across a temperature range of -40°C to 65°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when inventory constraints, lead time requirements, or application-specific needs necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PSU5335A is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Capacitance: 53 µF
• Voltage Rating: 250 V
• Tolerance: 0%, +20%
• Polarization: Bi-Polar

Mechanical Parameters (Must Match Exactly):

• Package Type: Radial, Can - QC Terminals
• Mounting Type: Chassis Mount
• Diameter: 1.438" (36.53 mm)

Compliance Parameters (Must Match or Exceed):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The PSU5335 qualifies as a direct substitute for the PSU5335A. Both parts share identical electrical specifications, polarization characteristics, and mounting configuration. The primary difference is the seated height dimension: PSU5335A measures 2.750" (69.85 mm) while PSU5335 measures 3.435" (87.25 mm). This height variance permits substitution only in applications where the increased vertical clearance does not conflict with enclosure or assembly constraints.

Parameter Comparison

Engineering Selection Recommendations

Both PSU5335A and PSU5335 are active production components with ROHS3 compliance and identical electrical performance characteristics. Selection between these parts is determined by physical space constraints within the target application.

PSU5335A Selection Criteria:

• Applications with height-constrained mounting locations
• Enclosures or assemblies with vertical clearance limitations of 2.750" (69.85 mm) or less
• Original design specifications requiring the shorter profile

PSU5335 Selection Criteria:

• Applications where the increased height of 3.435" (87.25 mm) does not create assembly conflicts
• Situations where PSU5335A inventory is unavailable
• Designs with sufficient vertical clearance to accommodate the taller component

Both parts maintain identical electrical performance, temperature operating range, and compliance certifications. The substitution decision is purely mechanical and does not affect circuit functionality or reliability characteristics.

Frequently Asked Questions (FAQ)

Q: Can PSU5335 be used as a direct replacement for PSU5335A in all applications?

A: PSU5335 is electrically and functionally equivalent to PSU5335A. However, the seated height differs: PSU5335A is 2.750" (69.85 mm) tall while PSU5335 is 3.435" (87.25 mm) tall. Substitution is valid only if the application enclosure or assembly provides sufficient vertical clearance for the taller component.

Q: Are the electrical specifications identical between PSU5335A and PSU5335?

A: Yes. Both parts share identical capacitance (53 µF), voltage rating (250 V), tolerance (0%, +20%), polarization (Bi-Polar), and operating temperature range (-40°C ~ 65°C).

Q: Do both parts meet the same compliance standards?

A: Yes. Both PSU5335A and PSU5335 are ROHS3 compliant with moisture sensitivity level 1 (unlimited). Both carry REACH unaffected status and EAR99 ECCN classification.

Q: What is the primary difference between PSU5335A and PSU5335?

A: The primary difference is the seated height dimension. PSU5335A measures 2.750" (69.85 mm) while PSU5335 measures 3.435" (87.25 mm). Both maintain the same 1.438" (36.53 mm) diameter and identical electrical characteristics.

Q: Can these parts be used interchangeably in motor start applications?

A: Yes, provided the physical height difference does not conflict with the application's mechanical constraints. Both parts are rated for motor start applications and operate across the same temperature range.

Q: What mounting configuration do both parts use?

A: Both PSU5335A and PSU5335 are chassis mount components with radial, can-style packages featuring QC (quick connect) terminals.
