Engineering Selection Recommendations

Primary Substitute: C44PLGR6500RASK

The C44PLGR6500RASK is the direct substitute for the obsolete C44PLGR6500ZASJ. Both components are manufactured by KEMET and share identical electrical specifications, physical dimensions, and mounting characteristics. The substitute part carries active product status, ensuring ongoing availability and supply chain support.

The tolerance specification difference (±5% versus ±10%) represents an allowable relaxation that does not compromise circuit performance in power factor correction, commutation, and EMI/RFI suppression applications. Both parts maintain ROHS3 compliance and identical operating temperature ranges.

The C44PLGR6500RASK is suitable for direct replacement in all applications where the C44PLGR6500ZASJ was originally specified, with no circuit redesign or board layout modifications required.

Frequently Asked Questions (FAQ)

Q: Can the C44PLGR6500RASK be used as a direct replacement for the C44PLGR6500ZASJ?

A: Yes. The C44PLGR6500RASK is electrically and mechanically equivalent to the C44PLGR6500ZASJ. Both components feature identical capacitance (500 µF), voltage ratings (700V DC / 330V AC), dielectric material (polypropylene metallized), physical dimensions, and mounting specifications. No circuit modifications are required.

Q: What is the difference between the two parts?

A: The primary differences are product status and tolerance specification. The C44PLGR6500ZASJ is obsolete with ±5% tolerance, while the C44PLGR6500RASK is active with ±10% tolerance. The tolerance relaxation is within acceptable limits for the specified applications.

Q: Are the physical dimensions identical?

A: Yes. Both parts share identical dimensions: 2.953" diameter (75.00mm), 9.803" maximum seated height (249.00mm), and 1.378" lead spacing (35.00mm). No board layout or mechanical mounting changes are necessary.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the C44PLGR6500ZASJ and C44PLGR6500RASK are ROHS3 compliant and REACH unaffected. Compliance certifications are equivalent.

Q: What is the operating temperature range for both parts?

A: Both components operate across the identical temperature range of -25°C to 70°C.

Q: Are there any ESR or performance differences?

A: The main part specifies an ESR of 1.8 mOhms. ESR data for the substitute part was not provided in the available specifications. For applications where ESR is a critical design parameter, detailed performance verification against the original specification is necessary.
