Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LGU2P561MELZ is determined by the following criteria:

Critical Parameters (Must Match):

• Capacitance: 560 µF
• Tolerance: ±20%
• Lead Spacing: 0.394" (10.00 mm)
• Package / Case: Radial, Can - Snap-In
• Mounting Type: Through Hole
• Polarization: Polar

Allowable Variation Parameters:

• Voltage - Rated: 220 V (direct substitutes) or 250 V (upgrade substitutes)
• Lifetime @ Temperature: 2000 Hrs or 3000 Hrs @ 105°C
• Physical Dimensions (Diameter and Height): Variations permitted within PCB layout constraints
• Ripple Current ratings: Variations permitted based on application requirements

Substitution Categories:

Direct Substitutes maintain 220 V rating with identical electrical specifications but may differ in physical dimensions or series designation.

Upgrade Substitutes feature 250 V rated voltage, providing higher voltage margin while maintaining all other electrical parameters.

Similar Substitutes share core electrical specifications but may have reduced lifetime ratings (2000 Hrs vs. 3000 Hrs) or different physical dimensions.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Electrical Performance): LGN2P561MELZ40 is the primary direct substitute, maintaining 220 V rating and 3000-hour lifetime. Physical dimensions differ slightly (height 42.00 mm vs. 45.00 mm), requiring verification of PCB layout clearance. Both parts are ROHS3 compliant and Active status.

For Voltage Margin Enhancement: LGW2E561MELZ45 provides 250 V rated voltage while maintaining 560 µF capacitance and 3000-hour lifetime. This upgrade is suitable when circuit design permits higher voltage rating. Ripple current capability increases to 2.25 A @ 120 Hz and 3.375 A @ 50 kHz. ROHS3 compliant and Active status.

For Space-Constrained Applications: LGG2P561MELZ35 offers reduced height (37.00 mm) and maintains 220 V rating with ±20% tolerance. Lifetime is reduced to 2000 hours @ 105°C. Suitable only when application duty cycle permits shorter lifetime rating. ROHS3 compliant and Active status.

For Compact Footprint with Extended Lifetime: LGN2P561MELA35 combines 3000-hour lifetime with compact dimensions (25.00 mm diameter, 37.00 mm height). Electrical specifications match LGN2P561MELZ40 series. ROHS3 compliant and Active status.

For Lowest Profile Design: LGN2P561MELB25 provides the most compact height (27.00 mm) with 3000-hour lifetime and 220 V rating. Diameter increases to 30.00 mm. ROHS3 compliant and Active status.

All substitute parts maintain ROHS3 compliance and Active product status, ensuring regulatory alignment and supply continuity.

Frequently Asked Questions (FAQ)

Q: Can LGN2P561MELZ40 replace LGU2P561MELZ directly on the PCB? A: Yes, provided PCB layout accommodates the height difference of 3.00 mm (42.00 mm vs. 45.00 mm). Lead spacing remains identical at 10.00 mm. Electrical performance is equivalent at 560 µF, 220 V, 3000 Hrs @ 105°C.

Q: What is the advantage of using LGW2E561MELZ45 over the original part? A: LGW2E561MELZ45 provides 250 V rated voltage instead of 220 V, offering 30 V additional voltage margin. This reduces stress on the capacitor in circuits with voltage transients. Ripple current capability also increases by approximately 32%. Physical dimensions remain compatible with the original part.

Q: Can I use LGG2P561MELA30 or LGG2P561MELZ35 as permanent replacements? A: These parts are suitable only if application requirements permit 2000-hour lifetime at 105°C instead of 3000 hours. They are not recommended for continuous-duty applications requiring extended service life. Verify application duty cycle before selection.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts are ROHS3 compliant and maintain identical compliance status to the original LGU2P561MELZ.

Q: What physical dimension differences exist among the substitutes? A: Diameter ranges from 22.00 mm to 30.00 mm, and height ranges from 27.00 mm to 45.00 mm. Verify PCB layout constraints before selecting a substitute with different dimensions. Lead spacing remains constant at 10.00 mm across all parts.

Q: Do all substitutes maintain the same ripple current ratings? A: No. Ripple current varies by series. LGU and LGN series provide higher ripple current (1.7 A and 1.61 A @ 120 Hz respectively) compared to LGG series (1.45 A @ 120 Hz). Select based on circuit ripple current requirements.

Q: Is LGU2P561MELA interchangeable with LGU2P561MELZ? A: Both are LGU series with identical electrical specifications (560 µF, 220 V, 3000 Hrs @ 105°C, 1.7 A ripple current @ 120 Hz). Physical dimensions differ: LGU2P561MELA is 25.00 mm diameter × 40.00 mm height, while LGU2P561MELZ is 22.00 mm diameter × 45.00 mm height. Verify PCB layout compatibility.
