Substitute Part Grouping Explanation

Substitution eligibility for the LGY2W560MELZ is determined by the following critical parameters:

Capacitance: 56 µF (exact match required)
Voltage Rating: 450 V (exact match required)
Tolerance: ±20% (exact match required)
Package Type: Radial, Can - Snap-In (exact match required)
Lead Spacing: 0.394" (10.00 mm) (exact match required)
Operating Temperature Range: -25°C ~ 105°C (minimum requirement)
Polarization: Polar (exact match required)
Mounting Type: Through Hole (exact match required)

All substitute parts listed meet these core electrical and mechanical requirements. Variations in lifetime rating, ripple current capacity, physical dimensions (diameter and height), and ESR are secondary parameters that may influence selection based on application-specific thermal and electrical stress conditions.

Engineering Selection Recommendations

LGR2W560MELZ35 (Nichicon, Active): This direct Nichicon equivalent offers extended lifetime (10000 hours at 105°C) compared to the original LGY2W560MELZ (7000 hours). Identical electrical and mechanical specifications ensure drop-in compatibility. ROHS3 compliance and active product status support long-term availability.

LGN2W560MELY25 (Nichicon, Active): This Nichicon alternative meets all core electrical requirements with reduced physical dimensions (20.00 mm diameter, 27.00 mm height versus 22.00 mm and 37.00 mm). Suitable for space-constrained applications. Lifetime rating of 3000 hours at 105°C is lower than the original. ROHS3 compliant.

LGU2W560MELY (Nichicon, Active): This Nichicon option provides higher ripple current capacity (510 mA at 120 Hz and 729.3 mA at 50 kHz) with compact dimensions (20.00 mm diameter, 30.00 mm height). Lifetime rating of 3000 hours at 105°C. ROHS3 compliant.

381LR560M450H012 (Cornell Dubilier Electronics, Active): This cross-manufacturer substitute from CDE meets all core electrical and mechanical requirements. Offers highest ripple current capacity (670 mA at 120 Hz, 950 mA at 20 kHz) and lowest profile (25.00 mm height). ESR specified at 4.65 Ohm @ 120 Hz. ROHS3 compliant with MSL rating of 1 (Unlimited).

Frequently Asked Questions (FAQ)

Q: Can LGR2W560MELZ35 be used as a direct replacement for LGY2W560MELZ?

A: Yes. Both parts share identical capacitance (56 µF), voltage rating (450 V), tolerance (±20%), lead spacing (10.00 mm), and physical dimensions (22.00 mm diameter, 37.00 mm height). The LGR2W560MELZ35 provides extended lifetime (10000 hours versus 7000 hours at 105°C) and is ROHS3 compliant with active product status.

Q: What are the physical dimension differences among substitute options?

A: LGR2W560MELZ35 and 381LR560M450H012 maintain the original 22.00 mm diameter. LGN2W560MELY25 and LGU2W560MELY use a smaller 20.00 mm diameter. Height varies: LGY2W560MELZ (37.00 mm), LGR2W560MELZ35 (37.00 mm), LGN2W560MELY25 (27.00 mm), LGU2W560MELY (30.00 mm), and 381LR560M450H012 (25.00 mm). Verify PCB layout compatibility before selecting compact alternatives.

Q: How do lifetime ratings affect substitute selection?

A: Lifetime ratings indicate expected operational duration at maximum rated temperature (105°C). LGR2W560MELZ35 offers 10000 hours, matching or exceeding most application requirements. LGN2W560MELY25, LGU2W560MELY, and 381LR560M450H012 provide 3000 hours. Select based on thermal stress conditions and required service life in your application.

Q: Are all substitutes RoHS compliant?

A: Yes. LGR2W560MELZ35, LGN2W560MELY25, LGU2W560MELY, and 381LR560M450H012 are all ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: What is the significance of ripple current ratings?

A: Ripple current capacity indicates the maximum AC current the capacitor can handle at specified frequency without exceeding temperature limits. Higher ripple current ratings provide design margin in high-frequency or high-stress applications. 381LR560M450H012 offers the highest capacity (670 mA @ 120 Hz, 950 mA @ 20 kHz), followed by LGU2W560MELY (510 mA @ 120 Hz, 729.3 mA @ 50 kHz).

Q: Can I use a substitute with different physical dimensions?

A: Physical dimensions must be verified against PCB layout and mechanical constraints. LGN2W560MELY25 and LGU2W560MELY have smaller diameters (20.00 mm) and reduced heights, suitable for space-constrained designs. 381LR560M450H012 offers the most compact profile (25.00 mm height). Confirm mounting hole spacing and clearance before substitution.
