Substitute Part Grouping Explanation

Substitution logic for the LGU2Z561MELY is based on the following criteria:

Primary Matching Parameters:

Capacitance: 560 µF (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Mounting Type: Through Hole (exact match required)
Package Type: Radial, Can - Snap-In (exact match required)
Lead Spacing: 0.394" (10.00 mm) (exact match required)
Lifetime Rating: 3000 Hrs @ 105°C (exact match required)
Operating Temperature: -40°C ~ 105°C (exact match required)

Allowable Variations:

Voltage Rating: May be equal or higher than 180 V
Physical Dimensions (Diameter and Height): Variations permitted within snap-in package constraints
Ripple Current Ratings: Variations permitted based on dimensional changes
Manufacturer Series: Variations permitted (LGU, LGN series)

Substitute parts are grouped into two categories: Upgrade substitutes (higher voltage rating) and Similar substitutes (same voltage rating with dimensional variations).

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and full ROHS3 and REACH compliance, ensuring long-term availability and regulatory alignment with the original LGU2Z561MELY.

Upgrade Substitutes (Higher Voltage Rating): LGN2D561MELY40 and LGU2D561MELY both provide 200 V rated voltage, offering enhanced voltage margin over the original 180 V specification. These parts are electrically interchangeable in applications where the 180 V rating is sufficient, as they maintain identical capacitance, tolerance, thermal rating, and lead spacing. Physical height variations (42.00 mm and 50.00 mm respectively) must be verified against PCB layout constraints.

Similar Substitutes (Same Voltage Rating, Dimensional Variants): LGU2Z561MELA, LGU2Z561MELB, and LGU2Z561MELZ maintain the 180 V voltage rating and offer alternative physical dimensions within the snap-in package family. These parts are suitable for applications where voltage margin is not required and dimensional flexibility exists. All maintain identical electrical performance parameters (capacitance, tolerance, thermal rating, lead spacing).

Selection should prioritize parts matching the original physical envelope unless PCB layout permits dimensional variation.

Frequently Asked Questions (FAQ)

Q: Can LGN2D561MELY40 or LGU2D561MELY replace LGU2Z561MELY directly?

A: Yes, both 200 V rated parts are electrically interchangeable. The higher voltage rating provides additional safety margin. Verify that the physical height (42.00 mm for LGN2D561MELY40 or 50.00 mm for LGU2D561MELY) fits within your PCB layout, as both differ from the original 45.00 mm height.

Q: What is the difference between LGU2Z561MELA, LGU2Z561MELB, and LGU2Z561MELZ?

A: All three maintain identical electrical specifications (560 µF, 180 V, ±20%, 3000 Hrs @ 105°C). The differences are physical dimensions: LGU2Z561MELA is 25.00 mm diameter × 30.00 mm height, LGU2Z561MELB is 30.00 mm diameter × 25.00 mm height, and LGU2Z561MELZ is 22.00 mm diameter × 40.00 mm height. Select based on available PCB space.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all listed substitute parts are ROHS3 compliant and REACH unaffected, matching the compliance status of the original LGU2Z561MELY.

Q: Can I use a lower voltage rated part as a substitute?

A: No. Voltage rating must be equal to or higher than the original 180 V specification. Using a lower voltage rating creates electrical stress and reliability risk.

Q: Do the dimensional variants affect electrical performance?

A: No. All substitute parts maintain identical capacitance (560 µF), tolerance (±20%), and thermal rating (3000 Hrs @ 105°C). Dimensional variations are physical only and do not alter electrical characteristics.
