Engineering Selection Recommendations

The C4ATJBU4300A3GK from KEMET is a direct parametric equivalent to the PHB1604300KJS. Both components are active production parts with ROHS3 compliance and identical mechanical and electrical core specifications. The KEMET substitute provides enhanced performance characteristics: a 100V higher DC voltage rating (700V vs. 600V), a 50V higher AC voltage rating (400V vs. 350V), and a lower equivalent series resistance (3.4 mOhms vs. 4.3 mOhms). These performance improvements position the substitute as suitable for applications requiring higher voltage margins or lower impedance characteristics while maintaining full compatibility with existing PCB layouts and through-hole assembly processes. Both parts are classified under ECCN EAR99 and HTSUS 8532.25.0020.

Frequently Asked Questions (FAQ)

Q: Can the C4ATJBU4300A3GK substitute be used in place of the PHB1604300KJS without PCB modifications?

A: Yes. Both components share identical physical dimensions (32.00 × 22.00 mm), height (37.00 mm), and lead spacing (27.50 mm). The radial through-hole configuration and PC pin termination are identical, permitting direct board-level substitution without layout changes.

Q: What is the significance of the lower ESR in the KEMET substitute?

A: The C4ATJBU4300A3GK exhibits an ESR of 3.4 mOhms compared to 4.3 mOhms in the Nichicon part. Lower ESR reduces impedance and heat generation in high-frequency and switching applications, improving overall circuit efficiency and thermal performance.

Q: Are both parts suitable for the same application categories?

A: The Nichicon PHB1604300KJS is specified for high-frequency and switching applications. The KEMET C4ATJBU4300A3GK is specified for DC link, DC filtering, high-frequency, and switching applications. The KEMET part encompasses all Nichicon applications and extends to additional DC filtering use cases.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both the PHB1604300KJS and C4ATJBU4300A3GK are ROHS3 compliant, classified under ECCN EAR99, and carry HTSUS code 8532.25.0020. Both operate across the identical temperature range of -40°C to 85°C.

Q: What is the practical difference between the 600V and 700V DC ratings?

A: The 700V rating of the KEMET substitute provides a 16.7% higher voltage margin above the 600V specification of the Nichicon part. This additional margin enhances component reliability and longevity in applications operating near maximum rated voltage.

Q: Are there any packaging or inventory considerations between these parts?

A: The Nichicon PHB1604300KJS is available in 968 units in stock. The KEMET C4ATJBU4300A3GK is available in 781 units in stock. The Nichicon part is packaged in standard format, while the KEMET substitute is supplied in bulk packaging.
