Substitute Part Grouping Explanation

Substitution eligibility for the LGN2C471MELY30 is determined by strict equivalence across the following critical parameters:

Capacitance: 470 µF (exact match required)
Voltage Rating: 160 V (exact match required)
Tolerance: ±20% (exact match required)
Lifetime: 3000 Hrs @ 105°C (exact match required)
Operating Temperature: -40°C ~ 105°C (exact match required)
Polarization: Polar (exact match required)
Package Type: Radial, Can - Snap-In (exact match required)
Mounting Type: Through Hole (exact match required)
Lead Spacing: 0.394" (10.00 mm) (exact match required)

The identified substitute parts LGN2C471MELZ25 and LGU2C471MELZ meet all critical electrical parameters. Mechanical variations in case diameter and height are permissible within the snap-in radial can form factor, provided lead spacing remains constant at 10.00 mm and mounting type remains through-hole.

Engineering Selection Recommendations

All three parts—LGN2C471MELY30, LGN2C471MELZ25, and LGU2C471MELZ—are Active status components manufactured by Nichicon and carry ROHS3 compliance certification. Selection between these parts is based on mechanical fit requirements within the target application.

The LGN2C471MELY30 features a smaller case diameter (20.00 mm) and greater height (32.00 mm). The LGN2C471MELZ25 provides a compact height profile (27.00 mm) with a larger diameter (22.00 mm). The LGU2C471MELZ offers intermediate height (30.00 mm) with the same diameter as the LGN2C471MELZ25 and delivers higher ripple current capability at both 120 Hz (1.55 A) and 50 kHz (2.325 A).

All parts maintain identical electrical specifications: 470 µF capacitance, 160 V voltage rating, ±20% tolerance, 3000-hour lifetime at 105°C, and -40°C to 105°C operating range. Lead spacing is constant at 10.00 mm across all variants, ensuring compatibility with standard through-hole PCB layouts designed for snap-in radial capacitors.

Frequently Asked Questions (FAQ)

Q: Can LGN2C471MELZ25 or LGU2C471MELZ be used as direct replacements for LGN2C471MELY30?

A: Yes, both parts are electrically equivalent. All three share identical capacitance (470 µF), voltage rating (160 V), tolerance (±20%), lifetime (3000 Hrs @ 105°C), and operating temperature range (-40°C ~ 105°C). Lead spacing is constant at 10.00 mm. Substitution is valid provided the PCB layout accommodates the different case diameter and height dimensions.

Q: What are the mechanical differences between these parts?

A: The LGN2C471MELY30 has a case diameter of 20.00 mm and height of 32.00 mm. The LGN2C471MELZ25 has a diameter of 22.00 mm and height of 27.00 mm. The LGU2C471MELZ has a diameter of 22.00 mm and height of 30.00 mm. All maintain the same 10.00 mm lead spacing for through-hole mounting.

Q: Does the LGU2C471MELZ offer any performance advantage?

A: The LGU2C471MELZ delivers higher ripple current ratings: 1.55 A at 120 Hz and 2.325 A at 50 kHz, compared to 1.4 A and 2.1 A respectively for the other two parts. This provides additional margin in applications with elevated ripple current demands.

Q: Are all three parts RoHS compliant?

A: Yes, all three parts are ROHS3 compliant and carry Active product status from Nichicon.

Q: What is the significance of the different series designations (LGN vs. LGU)?

A: The series designation reflects the product line within Nichicon's aluminum electrolytic capacitor portfolio. Both LGN and LGU series meet the specified electrical and thermal requirements for this application. Selection between series is determined by mechanical fit and ripple current requirements.
