Substitute Part Grouping Explanation

The LGU2C331MELY qualifies for substitution with the Nichicon LGU2Z331MELY based on the following criteria:

Matching Parameters (Substitution Basis):

• Capacitance: 330 µF (identical)
• Tolerance: ±20% (identical)
• Lifetime @ Temperature: 3000 Hrs @ 105°C (identical)
• Operating Temperature Range: -40°C ~ 105°C (identical)
• Ripple Current @ 120 Hz: 1.2 A (identical)
• Ripple Current @ 50 kHz: 1.8 A (identical)
• Lead Spacing: 10.00 mm (identical)
• Diameter: 20.00 mm (identical)
• Height - Seated (Max): 30.00 mm (identical)
• Package Type: Radial, Can - Snap-In (identical)
• Mounting Type: Through Hole (identical)
• Series: LGU (identical)
• RoHS Status: ROHS3 Compliant (identical)

Differing Parameter:

• Voltage - Rated: 160 V (LGU2C331MELY) vs. 180 V (LGU2Z331MELY)

The LGU2Z331MELY provides a higher voltage rating while maintaining all other electrical and mechanical specifications. This substitution is valid for applications where the circuit voltage does not exceed 160 V, as the higher-rated component provides additional voltage margin without altering form factor, thermal performance, or ripple current handling.

Parameter Comparison

Engineering Selection Recommendations

Both the LGU2C331MELY and LGU2Z331MELY maintain Active product status with full RoHS3 compliance and REACH unaffected designation. Selection between these parts depends on circuit voltage requirements:

• LGU2C331MELY: Select when circuit design specifies 160 V rated voltage and component availability is confirmed.
• LGU2Z331MELY: Select when higher voltage margin is required within the same physical footprint and thermal performance envelope, or when the 160 V variant is unavailable.

Both components are suitable for general-purpose applications with identical thermal lifetime, ripple current handling, and mechanical compatibility. No additional testing or design modification is required when substituting between these parts, provided the circuit voltage remains within the lower-rated component's specification.

Frequently Asked Questions (FAQ)

Q: Can LGU2Z331MELY replace LGU2C331MELY in any application?

A: Yes, provided the circuit voltage does not exceed 160 V. The LGU2Z331MELY has a higher voltage rating (180 V) and identical electrical and mechanical specifications, making it a direct substitute for the 160 V variant.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both components have identical lead spacing (10.00 mm), diameter (20.00 mm), and seated height (30.00 mm). They use the same radial, can snap-in package and through-hole mounting configuration.

Q: Do these parts have the same thermal performance?

A: Yes. Both components have identical lifetime ratings of 3000 Hrs @ 105°C and the same operating temperature range of -40°C ~ 105°C.

Q: Are ripple current specifications the same?

A: Yes. Both parts handle 1.2 A @ 120 Hz and 1.8 A @ 50 kHz identically.

Q: What is the difference between these two parts?

A: The only difference is the rated voltage: LGU2C331MELY is rated at 160 V, while LGU2Z331MELY is rated at 180 V. All other specifications are identical.

Q: Are both parts RoHS3 compliant?

A: Yes. Both LGU2C331MELY and LGU2Z331MELY are ROHS3 compliant and REACH unaffected.
