Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LLS2C182MELC is determined by the following critical parameters:

• Capacitance value: 1800 µF (exact match required)
• Voltage rating: 160 V (exact match required)
• Package type: Radial, Can - Snap-In (exact match required)
• Lead spacing: 0.394" (10.00mm) (exact match required)
• Physical dimensions: 1.378" Dia × 1.378" Height (exact match required)
• Mounting type: Through Hole (exact match required)
• Polarization: Polar (exact match required)

The LGU2C182MELC qualifies as a substitute part because it maintains identical electrical specifications (capacitance, voltage, tolerance) and mechanical compatibility (package, lead spacing, dimensions, mounting type). The primary difference is the thermal rating: the LGU2C series operates at -40°C ~ 105°C with a 3000-hour lifetime at 105°C, compared to the LLS2C series at -40°C ~ 85°C with a 3000-hour lifetime at 85°C. This makes the LGU2C182MELC suitable for applications requiring extended high-temperature operation.

Parameter Comparison

Engineering Selection Recommendations

Both the LLS2C182MELC and LGU2C182MELC are active production parts manufactured by Nichicon and maintain full ROHS3 compliance. Selection between these parts depends on application thermal requirements:

Select the LLS2C182MELC for applications operating within the -40°C ~ 85°C temperature range where the standard thermal rating is sufficient.

Select the LGU2C182MELC for applications requiring extended operation at elevated temperatures up to 105°C, or where higher thermal margin is required for reliability. Note that the LGU2C series exhibits lower ripple current ratings (3 A @ 120 Hz and 4.5 A @ 50 kHz) compared to the LLS2C series (4.28 A @ 120 Hz and 6.42 A @ 50 kHz).

Both parts are mechanically and electrically interchangeable in terms of footprint, lead spacing, and electrical ratings. PCB layout modifications are not required when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Can the LGU2C182MELC be used as a direct replacement for the LLS2C182MELC?

A: Yes, the LGU2C182MELC is mechanically and electrically compatible with the LLS2C182MELC. Both parts share identical capacitance (1800 µF), voltage rating (160 V), package type (Radial, Can - Snap-In), lead spacing (10.00mm), and physical dimensions. No PCB modifications are required.

Q: What is the primary difference between these two parts?

A: The primary difference is the operating temperature range and thermal lifetime rating. The LLS2C182MELC operates from -40°C ~ 85°C with a 3000-hour lifetime at 85°C. The LGU2C182MELC operates from -40°C ~ 105°C with a 3000-hour lifetime at 105°C. The LGU2C series also has lower ripple current specifications.

Q: Which part should I select for high-temperature applications?

A: For applications requiring sustained operation above 85°C, the LGU2C182MELC is the appropriate selection due to its extended temperature rating to 105°C.

Q: Are there any electrical performance differences I should consider?

A: Yes. The LGU2C182MELC has lower ripple current ratings: 3 A @ 120 Hz and 4.5 A @ 50 kHz, compared to the LLS2C182MELC at 4.28 A @ 120 Hz and 6.42 A @ 50 kHz. If your application requires high ripple current handling, verify that the LGU2C series ratings are adequate.

Q: Do both parts meet the same compliance standards?

A: Yes, both the LLS2C182MELC and LGU2C182MELC are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.
