Substitute Part Grouping Explanation

Substitution eligibility for the PSU5335 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)

Environmental Parameters (Must Match Exactly):

• Operating Temperature Range: -40°C to 65°C
• Moisture Sensitivity Level: 1 (Unlimited)

Compliance Parameters (Must Match Exactly):

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

The PSU5335A qualifies as a direct substitute because it maintains identical electrical specifications, equivalent mechanical form factor (with a reduced seated height), identical environmental ratings, and matching compliance certifications. Height variation does not disqualify substitution when chassis mounting clearance permits the reduced dimension.

Parameter Comparison

Engineering Selection Recommendations

PSU5335 Selection Criteria: The PSU5335 is appropriate for applications where the maximum seated height of 3.435" (87.25 mm) is required or where existing mechanical constraints specify this exact dimension. The component maintains active product status with confirmed inventory availability of 695 units. Full ROHS3 compliance and REACH unaffected status satisfy regulatory requirements for industrial and commercial motor start applications.

PSU5335A Selection Criteria: The PSU5335A provides identical electrical and environmental performance with a reduced seated height of 2.750" (69.85 mm), offering a 0.685" (17.4 mm) height reduction. This variant is suitable for space-constrained chassis designs where vertical clearance is limited. The PSU5335A maintains active product status with higher inventory availability of 1113 units. Compliance certifications are equivalent to the PSU5335.

Substitution Feasibility: Direct substitution between PSU5335 and PSU5335A is permissible when chassis mounting clearance accommodates the height differential. Both components are manufactured by the same supplier within the same product series, ensuring consistent quality and performance characteristics. Selection between these variants should be based solely on available vertical space within the target application.

Frequently Asked Questions (FAQ)

Q: Can PSU5335A replace PSU5335 in an existing design?

A: Yes, PSU5335A is a direct electrical and functional equivalent. The only difference is the seated height: PSU5335A measures 2.750" (69.85 mm) compared to PSU5335 at 3.435" (87.25 mm). Substitution is valid provided the reduced height does not conflict with chassis design constraints or component placement requirements.

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

A: Yes. Both components share identical capacitance (53 µF), voltage rating (250 V), tolerance (0%, +20%), polarization (bi-polar), and operating temperature range (-40°C to 65°C). Electrical performance in motor start applications is equivalent.

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

A: QC terminals refer to quick-connect terminals on the radial can package. Both PSU5335 and PSU5335A utilize this terminal type, ensuring mechanical and electrical compatibility with standard motor start circuit connections.

Q: Do both parts meet current compliance standards?

A: Yes. Both PSU5335 and PSU5335A are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for industrial component applications.

Q: Which part should be selected for new designs?

A: Selection depends on available vertical space. For space-constrained applications, PSU5335A is preferred due to its reduced height. For applications with no height restrictions, either part is acceptable. Both maintain active product status and adequate inventory levels.

Q: Is there a performance difference between the two parts?

A: No. Both components deliver identical electrical performance, environmental ratings, and reliability characteristics. The only functional difference is the physical height dimension.
