LGU2Z561MELZ Equivalent & Substitute Parts

Part Overview

The LGU2Z561MELZ is a 560 µF, 180 V aluminum electrolytic capacitor manufactured by Nichicon in the LGU series. This radial, can-style snap-in capacitor is rated for 3000 hours at 105°C and is designed for general-purpose applications requiring reliable energy storage and filtering. The part is currently active in production with ROHS3 compliance and REACH unaffected status.

Equivalent and substitute parts are necessary when the original part becomes unavailable, when design requirements change to accommodate higher voltage ratings, or when alternative mechanical configurations better suit specific PCB layouts and mounting constraints.

Substitute Part Grouping Explanation

Substitution of the LGU2Z561MELZ is determined by the following criteria:

Upgrade Substitutes maintain identical capacitance (560 µF) and tolerance (±20%) while increasing the voltage rating to 200 V. These parts are direct upgrades suitable for applications where higher voltage margin is required or where the original 180 V rating is no longer sufficient.

Similar Substitutes maintain identical electrical specifications (560 µF, 180 V, ±20%, 3000 Hrs @ 105°C) but differ in physical dimensions (diameter and height). These parts are compatible when PCB layout permits alternative can sizes while preserving the 10.00 mm lead spacing and through-hole mounting configuration.

All substitute parts share the following mandatory compatibility criteria:

Capacitance: 560 µF
Tolerance: ±20%
Lead Spacing: 0.394" (10.00 mm)
Mounting Type: Through Hole
Package Type: Radial, Can - Snap-In
Operating Temperature: -40°C ~ 105°C
Polarization: Polar
RoHS Status: ROHS3 Compliant

Engineering Selection Recommendations

For Direct Replacement (Same Voltage Rating): LGU2Z561MELA and LGU2Z561MELB are direct electrical equivalents to LGU2Z561MELZ, maintaining 560 µF capacitance at 180 V with identical electrical performance. Selection between these three parts depends solely on PCB layout constraints and available mounting space for the can diameter and height dimensions.

For Voltage Upgrade Applications: LGU2D561MELZ and LGN2D561MELZ35 provide 200 V voltage rating while maintaining 560 µF capacitance and ±20% tolerance. These upgrades are suitable when circuit requirements demand higher voltage margin or when the original 180 V specification no longer meets design criteria. Both parts maintain ROHS3 compliance and REACH unaffected status.

All listed parts are active products with current manufacturing status and full compliance certifications. Selection should be based on voltage requirement, available PCB space, and lead spacing compatibility (all parts maintain 10.00 mm lead spacing for through-hole mounting).

Frequently Asked Questions (FAQ)

Q: Can LGU2Z561MELA or LGU2Z561MELB be used as direct replacements for LGU2Z561MELZ? A: Yes. All three parts share identical electrical specifications: 560 µF, 180 V, ±20% tolerance, 3000 Hrs @ 105°C, and 10.00 mm lead spacing. The only differences are physical dimensions (can diameter and height). Substitution is valid if PCB layout accommodates the alternative can size.

Q: What is the difference between the 180 V and 200 V rated parts? A: The 200 V rated parts (LGU2D561MELZ and LGN2D561MELZ35) provide higher voltage margin for the same 560 µF capacitance. These are upgrades suitable for applications requiring increased voltage headroom or where circuit specifications have changed to demand higher voltage rating.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed parts maintain ROHS3 compliance and REACH unaffected status, ensuring compatibility with environmental and regulatory requirements.

Q: Does lead spacing differ between parts? A: No. All parts maintain 0.394" (10.00 mm) lead spacing for through-hole mounting. PCB footprints designed for LGU2Z561MELZ will accommodate all listed substitutes without modification to lead hole spacing.

Q: Which substitute part has the smallest physical footprint? A: LGN2D561MELZ35 has the smallest height at 1.457" (37.00 mm) while maintaining the same 0.866" (22.00 mm) diameter as the original LGU2Z561MELZ. This part is suitable when vertical space is constrained.
