LGU2Z221MELY Equivalent & Substitute Parts

Part Overview

The LGU2Z221MELY is a 220 µF, 180 V aluminum electrolytic capacitor manufactured by Nichicon in the LGU series. This radial, can-style snap-in capacitor is designed for general-purpose applications requiring reliable energy storage and filtering in circuits operating up to 180 V. The component is rated for 3000 hours at 105°C and operates across a temperature range of -40°C to 105°C. As an active product with ROHS3 compliance and REACH unaffected status, equivalent and substitute parts may be required due to inventory constraints, design upgrades, or voltage margin improvements in system applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LGU2Z221MELY is permissible with the LGU2D221MELY based on the following criteria:

Matching Parameters (Substitution Basis):

• Capacitance: 220 µF (identical)
• Tolerance: ±20% (identical)
• Lifetime @ Temperature: 3000 Hrs @ 105°C (identical)
• Operating Temperature Range: -40°C ~ 105°C (identical)
• Ripple Current @ 120 Hz: 1 A (identical)
• Ripple Current @ 50 kHz: 1.5 A (identical)
• Lead Spacing: 0.394" (10.00 mm) (identical)
• Size / Dimension: 0.787" Dia (20.00 mm) (identical)
• Height - Seated (Max): 0.984" (25.00 mm) (identical)
• Package / Case: Radial, Can - Snap-In (identical)
• Mounting Type: Through Hole (identical)
• RoHS Status: ROHS3 Compliant (identical)

Differing Parameter:

• Voltage - Rated: 200 V (substitute) vs. 180 V (main part)

The LGU2D221MELY operates at a higher rated voltage (200 V) while maintaining all other electrical and mechanical specifications. This substitution is valid for applications where the circuit voltage does not exceed 180 V, as the higher voltage rating provides additional safety margin without affecting performance at lower voltages.

Parameter Comparison

Engineering Selection Recommendations

Both the LGU2Z221MELY and LGU2D221MELY are active products with ROHS3 compliance and REACH unaffected status, ensuring regulatory compliance for current applications. The LGU2D221MELY is suitable as a direct substitute where circuit design permits operation at the higher 200 V rating. Selection between these parts should be based on circuit voltage requirements and availability. Both components maintain identical mechanical footprints, electrical performance characteristics, and thermal ratings, ensuring drop-in compatibility in through-hole applications.

Frequently Asked Questions (FAQ)

Q: Can the LGU2D221MELY replace the LGU2Z221MELY in my circuit?

A: Yes, the LGU2D221MELY is a valid substitute provided your circuit voltage does not exceed 180 V. The substitute part maintains identical capacitance, tolerance, ripple current ratings, thermal characteristics, and physical dimensions. The higher voltage rating (200 V) does not affect performance in lower-voltage applications.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts feature identical lead spacing (0.394" / 10.00 mm), diameter (0.787" / 20.00 mm), and seated height (0.984" / 25.00 mm). Both use radial, can-style snap-in packaging with through-hole mounting, ensuring mechanical compatibility on PCBs designed for either part.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the LGU2Z221MELY and LGU2D221MELY are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component applications.

Q: What is the key difference between these two parts?

A: The sole difference is the rated voltage: the LGU2Z221MELY is rated at 180 V, while the LGU2D221MELY is rated at 200 V. All other specifications, including capacitance, tolerance, ripple current, thermal ratings, and physical dimensions, are identical.

Q: Are there any thermal or lifetime differences?

A: No. Both parts are rated for 3000 hours at 105°C and operate across the same temperature range of -40°C to 105°C, ensuring equivalent reliability and lifespan in thermal applications.
