338LBA080M2DD Equivalent & Substitute Parts Reference

Part Overview

The 338LBA080M2DD is a 3300 µF, 80 V aluminum electrolytic capacitor manufactured by Cornell Dubilier / Illinois Capacitor in the LBA series. This radial, can-style snap-in capacitor is designed for general-purpose applications requiring high capacitance density in a compact through-hole package. The part is Active status and ROHS3 compliant.

Substitute parts are necessary when the original manufacturer part becomes unavailable, when inventory constraints require alternative sourcing, or when application requirements permit selection from qualified equivalent manufacturers. All substitute parts listed maintain identical electrical ratings and mechanical compatibility with the original specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for aluminum electrolytic capacitors is determined by strict equivalence across the following parameters:

Critical Parameters (Must Match Exactly):

• Capacitance: 3300 µF
• Voltage Rating: 80 V
• Tolerance: ±20%
• Package / Case: Radial, Can - Snap-In
• Lead Spacing: 0.394" (10.00mm)
• Physical Dimensions: 1.181" Dia × 1.260" Height (Max)
• Mounting Type: Through Hole
• Polarization: Polar

Acceptable Variation Parameters:

• Lifetime @ Temperature: Substitute parts may exceed the original specification
• Operating Temperature Range: Substitute parts may extend the upper temperature limit
• Ripple Current Ratings: Substitute parts may differ within the same frequency band
• ESR (Equivalent Series Resistance): Not specified for substitute parts; original specification is 125.6 mOhm @ 120Hz

All substitute parts listed maintain identical mechanical fit and electrical interface compatibility with the original 338LBA080M2DD specification.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are Active status products with ROHS3 compliance and REACH unaffected status, meeting the same regulatory requirements as the original 338LBA080M2DD.

80MXG3300MEFCSN30X30 (Rubycon MXG Series): This substitute extends the operating temperature range to 105°C and provides 3000 hours lifetime at 105°C, compared to the original 2000 hours at 85°C. The ripple current at 120 Hz is reduced to 2.64 A. This part is suitable for applications requiring extended temperature performance.

80USG3300MEFCSN30X30 (Rubycon USG Series): This substitute maintains the -40°C ~ 85°C operating temperature range and provides 3000 hours lifetime at 85°C, an improvement over the original 2000 hours. The ripple current at 120 Hz matches the original specification at 3.25 A. This part provides direct performance enhancement with identical thermal operating range.

LLS1K332MELB (Nichicon LLS Series): This substitute maintains the -40°C ~ 85°C operating temperature range and provides 3000 hours lifetime at 85°C. The ripple current at 120 Hz matches the original specification at 3.25 A. Highest inventory availability at 2095 pieces.

B41231C0338M000 (EPCOS - TDK Electronics B41231 Series): This substitute maintains the -40°C ~ 85°C operating temperature range and 2000 hours lifetime at 85°C, matching the original lifetime specification. The ripple current at 120 Hz is increased to 4.27 A, providing higher ripple current capability.

Frequently Asked Questions (FAQ)

Q: Can the 80MXG3300MEFCSN30X30 be used in place of the 338LBA080M2DD in all applications?

A: The 80MXG3300MEFCSN30X30 is mechanically and electrically compatible with the 338LBA080M2DD. The extended operating temperature range to 105°C and improved lifetime rating at elevated temperatures make it suitable for applications operating within the original -40°C ~ 85°C specification. Applications requiring operation above 85°C benefit from the extended temperature capability.

Q: What is the difference between the Rubycon USG and MXG series substitutes?

A: The 80USG3300MEFCSN30X30 operates to 85°C maximum with 3000 hours lifetime at 85°C. The 80MXG3300MEFCSN30X30 operates to 105°C maximum with 3000 hours lifetime at 105°C. Both maintain identical mechanical dimensions and electrical ratings. Selection depends on application temperature requirements.

Q: Are all substitute parts pin-compatible with the original 338LBA080M2DD?

A: Yes. All substitute parts maintain identical lead spacing of 0.394" (10.00mm), physical dimensions of 1.181" diameter × 1.260" height maximum, and through-hole radial snap-in package configuration. Direct mechanical and electrical substitution is possible without PCB modification.

Q: Which substitute part has the highest ripple current rating?

A: The B41231C0338M000 (EPCOS - TDK Electronics) provides the highest ripple current at 120 Hz at 4.27 A, compared to the original specification of 3.25 A.

Q: Do all substitute parts meet the same compliance standards as the original?

A: Yes. All substitute parts listed are ROHS3 compliant and REACH unaffected, matching the original 338LBA080M2DD compliance status.

Q: What is the inventory status of each substitute part?

A: 80MXG3300MEFCSN30X30: 776 pieces; 80USG3300MEFCSN30X30: 969 pieces; LLS1K332MELB: 2095 pieces; B41231C0338M000: 1271 pieces. All parts are listed as new original stock.
