Substitute Part Grouping Explanation

Substitute parts for the LGJ2Z331MELC15 are qualified based on the following criteria:

• Identical capacitance: 330 µF
• Identical voltage rating: 180 V
• Identical tolerance: ±20%
• Identical polarization: Polar
• Identical mounting type: Through Hole
• Identical package type: Radial, Can - Snap-In
• Identical lead spacing: 0.394" (10.00mm)
• Identical operating temperature range: -40°C ~ 105°C
• Identical compliance: ROHS3 Compliant

The substitute parts LGU2Z331MELY and LGU2Z331MELZ meet all electrical and mechanical compatibility requirements. These parts differ from the main part in physical dimensions and lifetime rating, which do not affect electrical interchangeability in applications where the snap-in package footprint accommodates the substitute dimensions.

Parameter Comparison

Engineering Selection Recommendations

All three parts—LGJ2Z331MELC15, LGU2Z331MELY, and LGU2Z331MELZ—are Active status components manufactured by Nichicon and are ROHS3 compliant. Selection between these parts is determined by application-specific requirements regarding physical dimensions and thermal lifetime rating.

The LGJ2Z331MELC15 features a larger diameter (35.00mm) and shorter height (17.00mm) with a 2000-hour lifetime rating at 105°C. The LGU2Z331MELY and LGU2Z331MELZ offer extended 3000-hour lifetime ratings at 105°C with smaller diameters (20.00mm and 22.00mm respectively) and greater heights (30.00mm and 25.00mm respectively). All parts maintain identical electrical specifications: 330 µF capacitance, 180 V voltage rating, ±20% tolerance, and 10.00mm lead spacing.

Selection should be based on available board space and thermal lifetime requirements for the target application. All substitute parts are electrically interchangeable with the main part when physical dimensions are accommodated by the circuit design.

Frequently Asked Questions (FAQ)

Q: Are LGU2Z331MELY and LGU2Z331MELZ electrically interchangeable with LGJ2Z331MELC15?

A: Yes. All three parts share identical electrical specifications: 330 µF capacitance, 180 V voltage rating, ±20% tolerance, -40°C to 105°C operating temperature range, and 10.00mm lead spacing. Electrical interchangeability is confirmed.

Q: What is the primary difference between these substitute parts?

A: The main differences are physical dimensions and thermal lifetime rating. LGJ2Z331MELC15 has a 35.00mm diameter and 17.00mm height with 2000-hour lifetime. LGU2Z331MELY has a 20.00mm diameter and 30.00mm height with 3000-hour lifetime. LGU2Z331MELZ has a 22.00mm diameter and 25.00mm height with 3000-hour lifetime. All maintain identical lead spacing of 10.00mm.

Q: Can I use a substitute part with different physical dimensions in my existing design?

A: Physical dimension compatibility depends on available board space and snap-in mounting clearance. Verify that the substitute part's diameter and height fit within the mechanical constraints of your application before implementation.

Q: Are all parts ROHS3 compliant?

A: Yes. LGJ2Z331MELC15, LGU2Z331MELY, and LGU2Z331MELZ are all ROHS3 compliant.

Q: What is the significance of the extended lifetime rating in LGU2Z331MELY and LGU2Z331MELZ?

A: The LGU series parts are rated for 3000 hours at 105°C compared to 2000 hours for the LGJ series. This extended rating indicates longer operational life under thermal stress, which may be relevant for applications requiring extended service intervals or operating in elevated temperature environments.
