Substitute Part Grouping Explanation

Substitution of the LLG2C182MELC30 is permissible when the following criteria are met:

• Capacitance value: 1800 µF (exact match required)
• Voltage rating: 160 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (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 × 1.260" Height (exact match required)
• Mounting type: Through Hole (exact match required)

The LGG2C182MELC30 qualifies as a substitute based on matching all electrical and mechanical parameters. Differences in ripple current ratings and operating temperature range do not preclude substitution when the application requirements fall within the substitute part's specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the LLG2C182MELC30 and LGG2C182MELC30 are active products manufactured by Nichicon with ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on application-specific thermal and ripple current requirements. The LLG2C182MELC30 supports higher ripple current ratings at 120 Hz and 50 kHz frequencies. The LGG2C182MELC30 extends the operating temperature range to 105°C and maintains rated lifetime at elevated temperatures. Both parts are suitable for general purpose applications and are mechanically and electrically interchangeable within their respective performance envelopes.

Frequently Asked Questions (FAQ)

Q: Can LGG2C182MELC30 be used as a direct replacement for LLG2C182MELC30?

A: Yes, when application requirements permit. Both parts share identical capacitance, voltage rating, tolerance, polarization, and physical dimensions. Verify that the application's ripple current demands do not exceed the LGG2C182MELC30 specifications (2.55 A @ 120 Hz, 3.825 A @ 50 kHz).

Q: What are the key differences between these two parts?

A: The primary differences are operating temperature range (LLG: -40°C to 85°C; LGG: -40°C to 105°C), lifetime rating temperature (LLG: 2000 Hrs @ 85°C; LGG: 2000 Hrs @ 105°C), and ripple current capacity. The LLG2C182MELC30 provides higher ripple current handling.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical lead spacing (0.394" / 10.00mm), diameter (1.378" / 35.00mm), and maximum seated height (1.260" / 32.00mm). They are mechanically interchangeable on PCBs designed for snap-in radial capacitors.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the LLG2C182MELC30 and LGG2C182MELC30 are ROHS3 compliant and REACH unaffected, with identical ECCN (EAR99) and HTSUS (8532.22.0040) classifications.

Q: Which part should be selected for high-temperature applications?

A: The LGG2C182MELC30 is rated for operation up to 105°C and maintains its 2000-hour lifetime at this temperature, making it suitable for elevated thermal environments.
