Parameter Comparison

Engineering Selection Recommendations

478LBB080M2ED (Cornell Dubilier / Illinois Capacitor - LBB Series)

This substitute offers improved performance characteristics over the 478LBA080M2ED. The ESR is reduced from 88.18 mOhm to 52.91 mOhm at 120 Hz, and the lifetime rating increases from 2000 hours to 3000 hours at 85°C. Ripple current capacity is higher across both low and high frequency ranges. All mechanical and electrical core parameters remain identical. This part is ROHS3 compliant and Active in product status.

SLPX472M080H3P3 (Cornell Dubilier Electronics - SLPX Series)

This substitute provides performance between the LBA and LBB series options. ESR is 71 mOhm at 120 Hz with a 3000-hour lifetime at 85°C. The seated height is reduced to 1.181" (30.00mm), which may be advantageous in space-constrained applications. Ripple current capacity is comparable to the LBB series. All core electrical and mechanical parameters match. This part is ROHS3 compliant and Active in product status.

B41231C478M (EPCOS - TDK Electronics - B41231 Series)

This substitute maintains identical core specifications with a 2000-hour lifetime at 85°C matching the original part. The ripple current capacity at 120 Hz is the highest among all options at 5.27 A. ESR data is not specified for this part. All mechanical parameters are identical to the 478LBA080M2ED. This part is ROHS3 compliant and Active in product status.

All substitute parts are suitable for direct replacement in applications where the 478LBA080M2ED is specified, provided that the performance variations in ESR, lifetime, and ripple current do not conflict with circuit design requirements.

Frequently Asked Questions (FAQ)

Q: Can the 478LBB080M2ED be used as a direct replacement for the 478LBA080M2ED?

A: Yes. Both parts share identical capacitance (4700 µF), voltage rating (80 V), tolerance (±20%), operating temperature range (-40°C ~ 85°C), package type (Radial, Can - Snap-In), lead spacing (0.394" / 10.00mm), and physical dimensions (1.378" Dia / 35.00mm). The 478LBB080M2ED offers lower ESR (52.91 mOhm vs. 88.18 mOhm) and extended lifetime (3000 hours vs. 2000 hours at 85°C).

Q: What is the difference between the SLPX472M080H3P3 and the 478LBA080M2ED?

A: The SLPX472M080H3P3 maintains all core electrical and mechanical specifications. The primary differences are ESR (71 mOhm vs. 88.18 mOhm), lifetime (3000 hours vs. 2000 hours at 85°C), and seated height (1.181" vs. 1.260"). The reduced height may provide advantages in compact PCB layouts.

Q: Is the B41231C478M compatible with the 478LBA080M2ED in all applications?

A: The B41231C478M is mechanically and electrically compatible. Core parameters including capacitance, voltage, tolerance, temperature range, package type, and dimensions are identical. The ripple current capacity is higher (5.27 A @ 120 Hz vs. 3.3 A). ESR is not specified for the B41231C478M, which should be considered in applications where ESR performance is critical.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (478LBB080M2ED, SLPX472M080H3P3, and B41231C478M) are ROHS3 compliant and Active in product status.

Q: What is the significance of ESR differences among these parts?

A: ESR (Equivalent Series Resistance) affects heat generation and voltage ripple performance. Lower ESR values result in reduced heat dissipation and improved ripple current handling. The 478LBB080M2ED (52.91 mOhm) and SLPX472M080H3P3 (71 mOhm) offer lower ESR than the 478LBA080M2ED (88.18 mOhm), making them suitable for applications with higher ripple current demands.

Q: Can the SLPX472M080H3P3 be used in space-constrained applications?

A: Yes. The SLPX472M080H3P3 has a seated height of 1.181" (30.00mm), which is 0.079" (2.00mm) shorter than the 478LBA080M2ED and other substitutes. This reduced height may provide advantages in compact PCB designs while maintaining all other mechanical and electrical specifications.

Q: What is the lifetime difference between these parts?

A: The 478LBA080M2ED and B41231C478M are rated for 2000 hours at 85°C. The 478LBB080M2ED and SLPX472M080H3P3 are rated for 3000 hours at 85°C, providing 50% extended operational life under the same thermal conditions.
