Nichicon LGN2Z561MELY40 Equivalent & Substitute Parts

Part Overview

The Nichicon LGN2Z561MELY40 is a 560 µF, 180 V aluminum electrolytic capacitor in radial, can snap-in package configuration. This component is designed for general-purpose applications requiring stable capacitance performance across an operating temperature range of -40°C to 105°C with a rated lifetime of 3000 hours at 105°C. The part maintains Active product status with full ROHS3 compliance and REACH unaffected certification.

Substitute parts are identified when design requirements permit voltage rating upgrades, dimensional variations within the same lead spacing, or series alternatives that maintain electrical performance specifications while offering improved availability or cost optimization.

Substitute Part Grouping Explanation

Substitution logic for the LGN2Z561MELY40 is based on the following criteria:

Upgrade Category: Parts with identical capacitance (560 µF) and tolerance (±20%), increased voltage rating (200 V), matching lead spacing (10.00 mm), and identical mounting type (Through Hole, Radial Can - Snap-In). These parts provide enhanced voltage margin while maintaining footprint compatibility.

Equivalent Category: Parts with identical electrical specifications (560 µF, ±20%, 180 V) and lead spacing (10.00 mm), but with dimensional variations in diameter and height. These parts maintain electrical performance and PCB footprint compatibility while offering alternative physical form factors within the same series family.

All substitute parts maintain:

• Identical capacitance value (560 µF)
• Identical tolerance (±20%)
• Identical lead spacing (10.00 mm)
• Identical mounting type (Through Hole)
• Identical package style (Radial, Can - Snap-In)
• Active product status
• ROHS3 compliance
• REACH unaffected certification

Parameter Comparison

Engineering Selection Recommendations

LGN2D561MELY40 (Upgrade Option): Select this part when circuit design permits voltage rating increase to 200 V. This upgrade maintains identical physical dimensions and lead spacing while providing enhanced voltage margin. The part carries Active product status, ROHS3 compliance, and increased inventory availability (1161 pcs). Ripple current ratings are marginally improved (1.6 A @ 120 Hz, 2.4 A @ 50 kHz).

LGU2Z561MELA, LGU2Z561MELB, LGU2Z561MELZ (Equivalent Options): Select these parts when dimensional variations are acceptable within PCB layout constraints. All three maintain identical electrical specifications (560 µF, 180 V, ±20% tolerance) and lead spacing (10.00 mm). Each offers distinct physical form factors:

• LGU2Z561MELA: 25.00 mm diameter, 30.00 mm height
• LGU2Z561MELB: 30.00 mm diameter, 25.00 mm height
• LGU2Z561MELZ: 22.00 mm diameter, 40.00 mm height

All substitute parts maintain Active product status and full compliance certifications (ROHS3, REACH unaffected).

Frequently Asked Questions (FAQ)

Q: Can LGN2D561MELY40 be used as a direct replacement for LGN2Z561MELY40?

A: Yes, when circuit design permits. LGN2D561MELY40 maintains identical physical dimensions (0.787" diameter, 1.654" height), lead spacing (10.00 mm), and mounting type. The 200 V rating provides voltage margin above the original 180 V specification. No PCB layout modifications are required.

Q: What is the difference between LGN and LGU series parts?

A: Both series are Nichicon aluminum electrolytic capacitors with identical electrical specifications (560 µF, 180 V, ±20% tolerance) and lead spacing (10.00 mm). The primary difference is physical form factor. LGN series uses a 20.00 mm diameter can, while LGU series offers three diameter options (22.00 mm, 25.00 mm, 30.00 mm) with corresponding height variations. Series selection depends on available PCB space.

Q: Are all substitute parts footprint compatible?

A: Lead spacing compatibility is maintained across all parts (10.00 mm). However, can diameter and height vary. LGN2Z561MELY40 and LGN2D561MELY40 are physically identical. LGU series parts require PCB layout verification due to dimensional differences in diameter and height, though lead spacing remains constant.

Q: Do substitute parts maintain the same thermal performance?

A: All parts maintain identical lifetime rating (3000 Hrs @ 105°C) and operating temperature range (-40°C ~ 105°C). Ripple current ratings vary slightly: LGN series at 1.5-1.6 A @ 120 Hz and 2.25-2.4 A @ 50 kHz; LGU series at 1.67 A @ 120 Hz and 2.505 A @ 50 kHz. These variations reflect different physical form factors but do not affect thermal classification.

Q: Are all substitute parts RoHS and REACH compliant?

A: Yes. All parts listed maintain ROHS3 compliance and REACH unaffected certification status, matching the original LGN2Z561MELY40 specifications.

Q: Which substitute part offers the best availability?

A: LGN2D561MELY40 offers the highest inventory level at 1161 pcs, followed by LGU2Z561MELA at 770 pcs and LGU2Z561MELB at 727 pcs. LGU2Z561MELZ maintains 696 pcs in stock.
