Substitute Part Grouping Explanation

Substitution eligibility for the LGN2P221MELY25 is determined by strict equivalence across the following critical parameters:

• Capacitance value: 220 µF (exact match required)
• Rated voltage: 220 V (exact match required)
• Tolerance: ±20% (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)
• Lifetime rating: 3000 Hrs @ 105°C (exact match required)
• Operating temperature range: -40°C ~ 105°C (exact match required)
• Compliance: RoHS3 Compliant (exact match required)

The Nichicon LGU2P221MELZ meets all substitution criteria and is classified as a direct equivalent part.

Parameter Comparison

Engineering Selection Recommendations

Both the LGN2P221MELY25 and LGU2P221MELZ are active production parts manufactured by Nichicon with full RoHS3 compliance and REACH unaffected status. Selection between these parts should be based on physical space constraints within the application. The LGN2P221MELY25 features a smaller diameter (20.00 mm) and greater height (27.00 mm), while the LGU2P221MELZ has a larger diameter (22.00 mm) and reduced height (25.00 mm). Both parts maintain identical electrical specifications including capacitance, voltage rating, tolerance, lifetime rating, and operating temperature range. The LGU2P221MELZ provides marginally higher ripple current capability at both 120 Hz and 50 kHz frequencies. PCB layout and mounting clearance requirements should determine the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the LGU2P221MELZ be used as a direct replacement for the LGN2P221MELY25?

A: Yes. Both parts are electrically equivalent with identical capacitance (220 µF), voltage rating (220 V), tolerance (±20%), lifetime (3000 Hrs @ 105°C), and operating temperature range (-40°C ~ 105°C). Physical dimensions differ; verify PCB layout accommodates the LGU2P221MELZ diameter of 22.00 mm and height of 25.00 mm.

Q: What are the physical differences between these parts?

A: The LGN2P221MELY25 measures 20.00 mm diameter by 27.00 mm height. The LGU2P221MELZ measures 22.00 mm diameter by 25.00 mm height. Both maintain 10.00 mm lead spacing and snap-in mounting configuration.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the LGN2P221MELY25 and LGU2P221MELZ are RoHS3 compliant and REACH unaffected.

Q: Do these parts have different ripple current ratings?

A: The ripple current specifications differ slightly. The LGN2P221MELY25 is rated at 980 mA @ 120 Hz and 1.47 A @ 50 kHz. The LGU2P221MELZ is rated at 1 A @ 120 Hz and 1.5 A @ 50 kHz. Both ratings are suitable for general purpose applications.

Q: What is the lead spacing for both parts?

A: Both parts feature 0.394" (10.00 mm) lead spacing, maintaining identical PCB footprint spacing for through-hole mounting.
