Parameter Comparison

Engineering Selection Recommendations

Both the 478LBA063M2CE and 380LQ472M063J032 are Active status products manufactured within the Cornell Dubilier corporate family. Both parts maintain full RoHS3 compliance and REACH unaffected designation, meeting current regulatory requirements for electronic component procurement.

The 380LQ472M063J032 substitute demonstrates improved electrical performance through lower ESR (88 mOhm versus 105.82 mOhm at 120 Hz), which reduces heat generation and improves ripple current handling efficiency. This performance advantage occurs within identical mechanical and thermal specifications.

Both parts share identical capacitance, voltage rating, tolerance, operating temperature range, lifetime rating, and physical dimensions. The snap-in mounting style and through-hole lead configuration ensure direct PCB compatibility without layout modification. Lead spacing of 10.00 mm and can diameter of 25.00 mm maintain identical footprint requirements.

Selection between these parts depends on component availability and supply chain considerations. The 380LQ472M063J032 currently maintains higher inventory levels (3532 pieces versus 1130 pieces), which may influence procurement decisions for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can the 380LQ472M063J032 directly replace the 478LBA063M2CE without PCB modification?

A: Yes. Both parts share identical lead spacing (10.00 mm), physical dimensions (25.00 mm diameter, 37.00 mm height), and snap-in mounting configuration. Direct substitution requires no PCB layout changes.

Q: What is the significance of the lower ESR in the 380LQ472M063J032?

A: The 380LQ472M063J032 exhibits 88 mOhm ESR compared to 105.82 mOhm in the 478LBA063M2CE. Lower ESR reduces resistive heating and improves capacitor performance under ripple current conditions. Both parts meet the same thermal and lifetime specifications.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the 478LBA063M2CE and 380LQ472M063J032 are RoHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component use in regulated markets.

Q: Do these parts have identical operating temperature ranges?

A: Yes. Both parts operate across -40°C to 85°C with a rated lifetime of 2000 hours at 85°C. Temperature performance is identical between the two parts.

Q: What is the tolerance specification for both parts?

A: Both parts carry ±20% capacitance tolerance. This tolerance applies to the 4700 µF nominal capacitance value, resulting in an acceptable range of 3760 µF to 5640 µF.

Q: Are there differences in ripple current ratings between these parts?

A: At 120 Hz low-frequency ripple, both parts are rated for 3.59 A. At high frequency, the 478LBA063M2CE is rated for 4.4875 A @ 10 kHz, while the 380LQ472M063J032 is rated for 4.13 A @ 20 kHz. The different frequency points reflect different measurement standards but do not affect general-purpose application suitability.

Q: What is the moisture sensitivity level for these capacitors?

A: Both parts carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or reflow processes.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. Identical electrical specifications (capacitance, voltage, tolerance, ESR, lifetime), mechanical dimensions, and mounting configuration enable direct interchangeability in circuit designs without design recalculation or PCB modification.
