Substitute Part Grouping Explanation

Substitution of the 338LMB080M2ED is determined by strict adherence to the following electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Capacitance value: 3300 µF (exact match required)
• Voltage rating: 80 V (minimum, equal or higher acceptable)
• Tolerance: ±20%
• Operating temperature: -40°C to 105°C (or equivalent range)
• Lifetime specification: 3000 Hrs @ 105°C (or equivalent)

Mechanical Compatibility Criteria:

• Package type: Radial, Can - Snap-In (exact match required)
• Mounting type: Through Hole
• Lead spacing: 0.394" (10.00mm)
• Size: 1.378" Dia (35.00mm)
• Height: 1.260" (32.00mm) maximum

Compliance Criteria:

• RoHS3 Compliant
• REACH Unaffected status

The substitute part LGU1K332MELC from Nichicon meets all electrical and mechanical compatibility requirements, confirming its validity as a direct parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the 338LMB080M2ED and LGU1K332MELC maintain active product status with ROHS3 compliance and REACH unaffected certifications. Selection between these parts should be based on:

Primary Considerations:

• Inventory availability and lead time from respective manufacturers
• Supply chain preference and qualified vendor relationships
• Ripple current performance requirements at operating frequencies

Secondary Considerations:

• ESR (Equivalent Series Resistance) specifications where available for the application
• Moisture sensitivity level, with the 338LMB080M2ED rated at MSL 1 (Unlimited) and LGU1K332MELC listed as Not Applicable

Both parts are electrically and mechanically interchangeable within the specified parameter tolerances and operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the LGU1K332MELC substitute directly for the 338LMB080M2ED in existing designs?

A: Yes. Both parts share identical electrical specifications (3300 µF, 80 V, ±20% tolerance, 3000 Hrs @ 105°C) and mechanical dimensions (1.378" diameter, 1.260" height, 10.00mm lead spacing). The radial, can-style snap-in package and through-hole mounting are identical, allowing direct board-level substitution.

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

A: The 338LMB080M2ED specifies 2.7 A @ 120 Hz (low frequency) and 3.375 A @ 10 kHz (high frequency). The LGU1K332MELC specifies 2.71 A @ 120 Hz and 3.1165 A @ 50 kHz. Selection should account for the specific ripple current profile of the application.

Q: What is the significance of the ESR specification for the main part?

A: The 338LMB080M2ED specifies 125.596 mOhm @ 120 Hz. ESR is critical for applications requiring low impedance at specific frequencies. The absence of ESR specification in the substitute part data does not preclude substitution but should be verified for noise-sensitive applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the 338LMB080M2ED and LGU1K332MELC are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: How does moisture sensitivity affect component selection?

A: The 338LMB080M2ED has Moisture Sensitivity Level 1 (Unlimited), indicating no moisture-related constraints. The LGU1K332MELC is listed as Not Applicable for MSL. Both parts are suitable for standard storage and handling conditions without special moisture control requirements.
