Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PSU6435A is determined by strict equivalence across the following critical parameters:

• Electrical Specifications: Capacitance value (64 µF), voltage rating (250 V), and tolerance band (0%, +20%) must be identical
• Polarization Type: Bi-polar configuration must be maintained
• Package and Terminal Configuration: Radial, can-style package with QC terminals is required
• Mounting Method: Chassis mount orientation must be preserved
• Temperature Operating Range: -40°C to 65°C compatibility is mandatory
• Compliance Standards: RoHS3 compliance and REACH unaffected status must be maintained

The PSU6435 qualifies as a direct substitute based on complete alignment with all electrical and mechanical parameters. Physical dimension variations in seated height do not affect electrical performance or circuit compatibility for this application category.

Parameter Comparison

Engineering Selection Recommendations

Both PSU6435A and PSU6435 are Active products manufactured by Cornell Dubilier Electronics and maintain full RoHS3 compliance with REACH unaffected status. Selection between these parts is based on physical space constraints within the chassis mount application.

PSU6435A is specified when maximum height clearance is limited to 2.750 inches (69.85 mm).

PSU6435 is specified when height clearance of 3.435 inches (87.25 mm) is available or required.

All other electrical, mechanical, and compliance parameters are identical, ensuring functional interchangeability within the respective height constraints. Both parts are suitable for motor start applications across the -40°C to 65°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can PSU6435 replace PSU6435A in any application?

A: PSU6435 is electrically and mechanically equivalent to PSU6435A with one exception: seated height. PSU6435 measures 3.435 inches maximum height compared to PSU6435A at 2.750 inches. Substitution is valid only if the application chassis provides sufficient vertical clearance for the taller component.

Q: Are the QC terminals identical between PSU6435A and PSU6435?

A: Yes. Both parts use identical QC terminal configurations for radial, can-style packages. Terminal compatibility is maintained across both part numbers.

Q: Do both parts meet the same compliance requirements?

A: Yes. PSU6435A and PSU6435 are both RoHS3 compliant, REACH unaffected, and carry identical MSL ratings of 1 (Unlimited). Compliance status is equivalent for both parts.

Q: What is the tolerance specification for these capacitors?

A: Both PSU6435A and PSU6435 carry a tolerance specification of 0%, +20%, meaning the actual capacitance value will not fall below the nominal 64 µF and will not exceed 76.8 µF.

Q: Are these parts suitable for motor start applications?

A: Yes. Both PSU6435A and PSU6435 are specified for motor start applications and operate across the required -40°C to 65°C temperature range.

Q: What is the difference in physical dimensions between these two parts?

A: The diameter is identical at 1.438 inches (36.53 mm). The seated height differs: PSU6435A is 2.750 inches (69.85 mm), while PSU6435 is 3.435 inches (87.25 mm). Diameter and all electrical specifications remain unchanged.
