Substitute Part Grouping Explanation

Substitution of the C44PLGR6400ZASJ is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Capacitance value: 400 µF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage Rating - DC: 700V (minimum requirement)
• Voltage Rating - AC: 330V (minimum requirement)
• Dielectric Material: Polypropylene (PP), Metallized (exact match required)
• Operating Temperature Range: -25°C ~ 70°C (minimum requirement)

Mechanical Equivalence Criteria:

• Mounting Type: Chassis Mount or Stud Mount (compatible mounting configurations)
• Package / Case: Radial, Can (exact match required)
• Termination: Threaded, Male (exact match required)

Compliance Criteria:

• RoHS3 Compliant (mandatory for equivalent substitution)
• REACH Unaffected status (maintained across all equivalents)

The substitute part C44PLGR6400RASJ meets all electrical and mechanical equivalence criteria while maintaining active product status and full regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The C44PLGR6400RASJ is the direct active equivalent for the obsolete C44PLGR6400ZASJ. Both components are manufactured by KEMET and maintain identical electrical specifications across capacitance, voltage rating, tolerance, and dielectric material. Both parts are ROHS3 compliant and REACH unaffected, satisfying regulatory requirements for current production and field replacement applications.

The primary design consideration is the dimensional difference: the substitute part features a larger diameter (75.00mm versus 65.00mm) and increased lead spacing (35.00mm versus 28.00mm). These dimensional changes require verification of mechanical fit within the target application's chassis or PCB layout. The identical height and threaded male termination ensure compatibility with existing mounting hardware and electrical connections.

The substitute part's active product status ensures ongoing availability and supply chain continuity, eliminating the obsolescence risk associated with the original part number.

Frequently Asked Questions (FAQ)

Q: Can the C44PLGR6400RASJ be used as a direct replacement for the C44PLGR6400ZASJ?

A: The C44PLGR6400RASJ is electrically equivalent to the C44PLGR6400ZASJ across all critical parameters: capacitance, voltage rating, tolerance, dielectric material, and operating temperature range. Mechanical compatibility depends on available space for the larger diameter (75.00mm versus 65.00mm) and increased lead spacing (35.00mm versus 28.00mm).

Q: What are the key differences between these two parts?

A: The primary differences are dimensional. The substitute part has a larger diameter and wider lead spacing. Both parts maintain identical electrical performance, height, and termination type. The substitute part is active, while the original is obsolete.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the C44PLGR6400ZASJ and C44PLGR6400RASJ are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: What mounting configurations are supported?

A: The original part supports chassis mount. The substitute part supports both chassis and stud mount configurations, providing additional flexibility for different application requirements.

Q: Will the increased lead spacing affect circuit board layout?

A: The lead spacing increase from 28.00mm to 35.00mm requires verification against the target PCB or chassis layout. If the original spacing is critical to the design, layout modifications may be necessary to accommodate the substitute part.

Q: Is the ESR specification maintained in the substitute part?

A: The ESR value of 2 mOhms is specified for the original part. ESR specification data for the substitute part was not provided in the available technical parameters.
