Frequently Asked Questions (FAQ)

Q: Can 108LBB080M2BC be used as a direct replacement for 108LBA080M2BC?

A: Yes. Both parts share identical capacitance (1000 µF), voltage rating (80 V), tolerance (±20%), package type (Radial, Can - Snap-In), lead spacing (10.00mm), physical dimensions (22.00mm diameter, 27.00mm height), and mounting configuration (Through Hole). The 108LBB080M2BC offers lower ESR and extended lifetime at the same operating temperature range (-40°C to 85°C).

Q: What is the primary difference between the Cornell Dubilier and Nichicon substitute options?

A: Cornell Dubilier substitutes (108LBB080M2BC and 381LX102M080H012) maintain the same manufacturer family. The 381LX102M080H012 extends the operating temperature to 105°C. Nichicon substitutes (LGU1K102MELZ and LGY1K102MELZ25) also extend operating temperature to 105°C, with the LGY series offering the longest lifetime rating (5000 hours at 105°C).

Q: Are all substitute parts mechanically interchangeable with the 108LBA080M2BC?

A: Yes. All substitute parts maintain identical mechanical specifications: 0.866" diameter (22.00mm), 1.063" maximum seated height (27.00mm), 0.394" lead spacing (10.00mm), radial snap-in package configuration, and through-hole mounting type. Physical board layout compatibility is preserved.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All substitute parts are ROHS3 compliant and REACH unaffected, matching the compliance profile of the 108LBA080M2BC.

Q: Which substitute should be selected for applications requiring extended service life?

A: The LGY1K102MELZ25 (Nichicon LGY series) provides the longest lifetime rating at 5000 hours at 105°C, compared to 2000 hours at 85°C for the original 108LBA080M2BC. This part is suitable for applications requiring maximum operational duration in elevated temperature environments.

Q: What is the significance of ESR differences between substitute parts?

A: ESR (Equivalent Series Resistance) affects impedance characteristics and heat dissipation. The 108LBB080M2BC exhibits lower ESR (248.68 mOhm at 120 Hz) compared to the 108LBA080M2BC (414.47 mOhm at 120 Hz), resulting in improved performance in high-ripple-current applications. Nichicon substitutes do not specify ESR values in the provided data.

Q: Can the 108LBA080M2BC be used in applications requiring 105°C operation?

A: No. The 108LBA080M2BC is rated for -40°C to 85°C operation. For applications requiring 105°C operation, select 381LX102M080H012, LGU1K102MELZ, or LGY1K102MELZ25.

Q: Are ripple current ratings identical across all substitute parts?

A: No. Ripple current ratings vary. The 108LBA080M2BC specifies 1.65 A at 120 Hz and 2.0625 A at 10 kHz. The 108LBB080M2BC specifies 1.5 A at 120 Hz and 1.875 A at 10 kHz. Nichicon parts specify ripple current at 50 kHz rather than 10 kHz. Verify ripple current specifications match application requirements.
