Substitute Part Grouping Explanation

Substitute parts for the Nichicon LGU2P221MELY are classified based on the following substitution criteria:

Upgrade Category: Parts with identical capacitance (220 µF) and tolerance (±20%), but with increased voltage rating (250 V vs. 220 V). These substitutes maintain all electrical performance parameters and are suitable for applications where higher voltage margin is acceptable or required.

Similar Category: Parts with identical electrical specifications (220 µF, 220 V, ±20%, 3000 Hrs @ 105°C) but with dimensional variations in the radial can package. These maintain full electrical compatibility while offering alternative physical footprints for different PCB layouts.

The following parameters determine substitution eligibility:

• Capacitance value must remain 220 µF
• Tolerance must remain ±20%
• Voltage rating must be equal to or greater than 220 V
• Lifetime rating must be 3000 Hrs @ 105°C or greater
• Operating temperature range must encompass -40°C ~ 105°C
• Polarization must remain Polar
• Package type must remain Radial, Can - Snap-In
• Mounting type must remain Through Hole
• RoHS3 compliance must be maintained

Engineering Selection Recommendations

LGU2E221MELY (Upgrade Substitute): This part is suitable for direct substitution in applications where a higher voltage rating margin is beneficial or required. The 250 V rating provides increased safety margin over the 220 V specification while maintaining identical capacitance, tolerance, thermal performance, and ripple current ratings. All compliance certifications (ROHS3, REACH Unaffected, EAR99) are maintained. This substitute is recommended when circuit design permits voltage rating elevation without adverse effects.

LGU2P221MELZ (Similar Substitute): This part maintains identical electrical specifications and voltage rating as the main part but differs in physical dimensions. The can diameter increases from 0.787" (20.00 mm) to 0.866" (22.00 mm), while the seated height decreases from 1.181" (30.00 mm) to 0.984" (25.00 mm). This substitute is suitable only when PCB layout accommodates the larger diameter and reduced height. All electrical performance, thermal ratings, and compliance certifications remain unchanged. Lead spacing remains constant at 0.394" (10.00 mm), ensuring compatibility with existing through-hole footprints.

Both substitutes maintain Active product status and full regulatory compliance, making them suitable for production applications.

Frequently Asked Questions (FAQ)

Q: Can LGU2E221MELY be used as a direct replacement for LGU2P221MELY?

A: Yes. The LGU2E221MELY is electrically and mechanically compatible. The primary difference is the increased voltage rating (250 V vs. 220 V), which provides additional safety margin. Physical dimensions and lead spacing are identical. Verify that the circuit design permits operation at the higher voltage rating.

Q: What is the difference between LGU2P221MELY and LGU2P221MELZ?

A: Both parts have identical electrical specifications (220 µF, 220 V, ±20%, 3000 Hrs @ 105°C). The difference is physical: LGU2P221MELZ has a larger diameter (0.866" vs. 0.787") and shorter height (0.984" vs. 1.181"). Lead spacing remains 0.394" (10.00 mm). Substitution is possible only if PCB layout accommodates the dimensional change.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. LGU2E221MELY and LGU2P221MELZ are both ROHS3 Compliant, matching the main part specification.

Q: Can I use a substitute part with a higher voltage rating in a 220 V circuit?

A: Yes. Using a higher voltage-rated capacitor (250 V) in a 220 V circuit is electrically safe and is a common engineering practice. The capacitor will operate within its rated specifications with additional voltage margin.

Q: Do the substitute parts have the same ripple current ratings?

A: Yes. All substitute parts maintain identical ripple current specifications: 1 A @ 120 Hz and 1.5 A @ 50 kHz.

Q: What is the lead spacing for all these parts?

A: All three parts (LGU2P221MELY, LGU2E221MELY, and LGU2P221MELZ) have a lead spacing of 0.394" (10.00 mm), ensuring compatibility with standard through-hole PCB footprints.
