PSU6435 Equivalent & Substitute Parts Reference

Part Overview

The PSU6435 is a 64 µF, 250 V aluminum electrolytic capacitor with radial, can-style QC terminals manufactured by Cornell Dubilier Electronics (CDE). This component is designed for motor start applications and operates across a temperature range of -40°C to 65°C. The part maintains Active product status with full ROHS3 compliance and REACH unaffected classification. Substitute parts are identified when inventory constraints, lead time requirements, or procurement logistics necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the PSU6435 is determined by strict equivalence across the following parameters:

• Capacitance Value: 64 µF (exact match required)
• Voltage Rating: 250 V (exact match required)
• Tolerance: 0%, +20% (exact match required)
• Polarization: Bi-Polar (exact match required)
• Operating Temperature Range: -40°C to 65°C (exact match required)
• Package Configuration: Radial, Can - QC Terminals (exact match required)
• Mounting Type: Chassis Mount (exact match required)
• Diameter: 1.438" (36.53 mm) (exact match required)
• Manufacturer: Cornell Dubilier Electronics (CDE) (same manufacturer required)
• Series: PSU (same series required)
• Compliance: ROHS3 Compliant, REACH Unaffected (exact match required)

The PSU6435A qualifies as a direct substitute based on complete alignment with all electrical and mechanical parameters listed above.

Parameter Comparison

Engineering Selection Recommendations

Both PSU6435 and PSU6435A are Active products manufactured by Cornell Dubilier Electronics and carry identical ROHS3 compliance and REACH unaffected certifications. Selection between these parts should be based on the following engineering considerations:

Physical Dimension Variance: The PSU6435A has a reduced seated height of 2.750" (69.85 mm) compared to the PSU6435 at 3.435" (87.25 mm). This 0.685" (17.40 mm) height difference must be evaluated against available chassis clearance and PCB layout constraints. Both parts maintain identical diameter specifications of 1.438" (36.53 mm).

Electrical Equivalence: All electrical parameters—capacitance, voltage rating, tolerance, polarization, and operating temperature range—are identical between both parts. Motor start application requirements are fully satisfied by either component.

Inventory and Availability: Both parts are currently in stock with comparable inventory levels (PSU6435: 767 pcs; PSU6435A: 735 pcs). Selection may be driven by procurement lead time or supply chain logistics.

Compliance Status: Both parts maintain identical regulatory compliance certifications, ensuring interchangeability from a standards perspective.

Frequently Asked Questions (FAQ)

Q: Can PSU6435A be used as a direct replacement for PSU6435?

A: PSU6435A qualifies as a direct electrical substitute for PSU6435. All electrical parameters—capacitance (64 µF), voltage rating (250 V), tolerance (0%, +20%), polarization (Bi-Polar), and operating temperature range (-40°C to 65°C)—are identical. The primary difference is the seated height: PSU6435A measures 2.750" (69.85 mm) versus PSU6435 at 3.435" (87.25 mm). Mechanical fit must be verified against available chassis clearance before substitution.

Q: What are the critical parameters for substituting PSU6435?

A: Substitution eligibility requires exact matching of: capacitance value (64 µF), voltage rating (250 V), tolerance specification (0%, +20%), polarization type (Bi-Polar), operating temperature range (-40°C to 65°C), package configuration (Radial, Can - QC Terminals), mounting type (Chassis Mount), and diameter (1.438" / 36.53 mm). Manufacturer (Cornell Dubilier Electronics) and series designation (PSU) must also remain constant.

Q: Are there any compliance differences between PSU6435 and PSU6435A?

A: No. Both parts carry identical ROHS3 compliance and REACH unaffected certifications. Regulatory and environmental compliance requirements are fully satisfied by either component.

Q: What is the significance of the height difference between these parts?

A: The PSU6435A seated height of 2.750" (69.85 mm) is 0.685" (17.40 mm) shorter than the PSU6435 at 3.435" (87.25 mm). This dimensional variance affects physical fit within the chassis or enclosure. Applications with space constraints may benefit from the PSU6435A, while applications with existing mechanical clearance designed for the taller PSU6435 should verify fit before substitution.

Q: Are both parts suitable for motor start applications?

A: Yes. Both PSU6435 and PSU6435A are specified for motor start applications and maintain identical electrical characteristics required for this function.

Q: What inventory status should influence part selection?

A: Both parts are currently in stock with comparable availability (PSU6435: 767 pcs; PSU6435A: 735 pcs). Selection may be influenced by procurement logistics, lead time requirements, or supply chain considerations rather than availability constraints.
