Nichicon LGU2E221MELY 220µF 250V Aluminum Electrolytic Capacitor

Part Overview

The Nichicon LGU2E221MELY is a 220 µF, 250 V aluminum electrolytic capacitor in radial, can snap-in package configuration. This through-hole component is rated for 3000 hours at 105°C and operates across the temperature range of -40°C to 105°C. The part maintains Active product status and is ROHS3 compliant, making it suitable for general-purpose applications requiring stable capacitance and ripple current handling.

Equivalent and substitute parts are necessary when the primary part number becomes unavailable, when design revisions require alternative manufacturers, or when specific performance characteristics of substitute models better match application requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LGU2E221MELY is determined by strict equivalence across the following parameters:

• Capacitance: 220 µF (exact match required)
• Voltage Rating: 250 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Lead Spacing: 0.394" (10.00mm) (exact match required)
• Package Type: Radial, Can - Snap-In (exact match required)
• Mounting Type: Through Hole (exact match required)

All substitute parts listed meet these core electrical and mechanical requirements. Variations in physical dimensions (diameter and height), ripple current ratings, ESR specifications, and lifetime ratings are permissible provided the part fits the PCB footprint and meets or exceeds the application's performance demands.

Parameter Comparison

Engineering Selection Recommendations

Nichicon LGU2E221MELZ is the primary substitute for the LGU2E221MELY. Both parts are from the same manufacturer's LGU series, maintain Active product status, and share identical electrical specifications. The LGU2E221MELZ differs only in physical dimensions (0.866" diameter, 0.984" height versus 0.787" diameter, 1.181" height), making it suitable for applications where PCB space permits the alternative form factor.

Nichicon LGJ2E221MELB is an alternative from Nichicon's LGJ series with Active status. Physical dimensions differ significantly (1.181" diameter, 0.866" height), and ripple current ratings are slightly lower (950 mA @ 120 Hz versus 1 A @ 120 Hz). This part is appropriate for applications with less stringent ripple current requirements and adequate PCB clearance.

EPCOS B43504A2227M000 meets all core electrical requirements but carries "Not For New Designs" product status. This part is suitable only for legacy system maintenance or replacement scenarios where new design qualification is not required. The part exhibits higher ESR (580 mOhm @ 100 Hz) and lower ripple current (890 mA @ 100 Hz) compared to the primary part.

Cornell Dubilier LP221M250E1P3 is an Active product from an alternative manufacturer. This part has a reduced lifetime rating of 1000 hours at 105°C (versus 3000 hours for the primary part) and lower ripple current specifications (710 mA @ 120 Hz). Selection of this part requires confirmation that the application's thermal and ripple current demands do not exceed these reduced ratings.

Frequently Asked Questions (FAQ)

Q: Can I use LGU2E221MELZ as a direct replacement for LGU2E221MELY?

A: Yes. Both parts share identical electrical specifications (220 µF, 250 V, ±20%, 3000 Hrs @ 105°C) and lead spacing (10.00mm). The substitute differs only in physical dimensions. Verify that your PCB layout accommodates the 0.866" diameter and 0.984" height before installation.

Q: What is the difference between the Nichicon LGU and LGJ series substitutes?

A: Both are Nichicon products with identical capacitance, voltage, and tolerance. The LGJ2E221MELB has different physical dimensions and slightly lower ripple current capacity (950 mA @ 120 Hz versus 1 A @ 120 Hz). Select based on available PCB space and ripple current requirements.

Q: Why is the EPCOS B43504A2227M000 marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development and recommends against use in new product designs. The part remains available for legacy system support and field replacements where existing designs are already in production.

Q: Can I use the Cornell Dubilier LP221M250E1P3 in a high-temperature application?

A: The LP221M250E1P3 has a lifetime rating of 1000 hours at 105°C, compared to 3000 hours for the primary part. Applications requiring extended operation at elevated temperatures should use parts with higher lifetime ratings. Confirm your application's thermal profile before selection.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the primary part's environmental compliance status.

Q: What happens if my PCB layout cannot accommodate the larger physical dimensions of substitute parts?

A: Verify the specific dimensions of each candidate part against your PCB footprint. The LGU2E221MELZ (0.866" diameter, 0.984" height) is the closest dimensional match to the primary part. If space constraints are critical, confirm mechanical clearance before procurement.
