• Mounting Type: Through Hole (exact match required)
• Lead Spacing: 0.394" (10.00 mm) (exact match required)
• Compliance Status: RoHS3 Compliant, REACH Unaffected (exact match required)

The Nichicon LGJ2E181MELA meets all mandatory substitution criteria and is classified as a direct equivalent part.

Parameter Comparison

Engineering Selection Recommendations

Both the Nichicon LGU2E181MELY and LGJ2E181MELA maintain active product status with identical electrical specifications and compliance certifications. Selection between these parts is based on physical form factor requirements and ripple current handling capacity.

The LGU2E181MELY features a smaller diameter (20.00 mm) with greater height (30.00 mm) and supports higher ripple current ratings at both low frequency (900 mA @ 120 Hz) and high frequency (1.35 A @ 50 kHz).

The LGJ2E181MELA features a larger diameter (25.00 mm) with reduced height (22.00 mm) and supports lower ripple current ratings at both low frequency (750 mA @ 120 Hz) and high frequency (1.125 A @ 50 kHz).

Both parts satisfy RoHS3 compliance and REACH unaffected requirements for regulated applications.

Frequently Asked Questions (FAQ)

Q: Can the LGJ2E181MELA replace the LGU2E181MELY in all applications?

A: Electrical substitution is valid when capacitance, voltage rating, tolerance, lifetime, and operating temperature specifications are identical. Physical form factor differences (diameter and height) must be evaluated against PCB layout constraints and available mounting space. Ripple current ratings differ between the two parts and must be assessed against circuit requirements.

Q: What are the key differences between these substitute parts?

A: The primary differences are physical dimensions and ripple current handling. The LGU2E181MELY is narrower (20.00 mm diameter) and taller (30.00 mm height) with higher ripple current capacity. The LGJ2E181MELA is wider (25.00 mm diameter) and shorter (22.00 mm height) with lower ripple current capacity. All electrical parameters remain identical.

Q: Are both parts compliant with environmental regulations?

A: Both the LGU2E181MELY and LGJ2E181MELA are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What determines whether a part can substitute for the LGU2E181MELY?

A: Substitution requires exact matching of capacitance (180 µF), voltage rating (250 V), tolerance (±20%), lifetime specification (3000 Hrs @ 105°C), operating temperature range (-40°C ~ 105°C), polarization (Polar), package type (Radial, Can - Snap-In), mounting type (Through Hole), lead spacing (0.394" / 10.00 mm), and compliance status (RoHS3 Compliant, REACH Unaffected).
