Equivalent & Substitute Parts for LGU2C471MELY

Part Overview

The LGU2C471MELY is a 470 µF, 160 V aluminum electrolytic capacitor manufactured by Nichicon in the LGU series. This radial, can-style snap-in capacitor is designed for general-purpose applications requiring stable capacitance and extended operational life. With an active product status and full RoHS3 compliance, this component remains in production and is suitable for new designs and legacy system replacements. Equivalent and substitute parts are identified when identical electrical specifications and compatible mechanical dimensions allow direct functional replacement in circuit applications.

Substitute Part Grouping Explanation

Substitute parts for the LGU2C471MELY are identified based on strict equivalence of core electrical parameters: capacitance value (470 µF), voltage rating (160 V), tolerance (±20%), thermal lifetime (3000 Hrs @ 105°C), and operating temperature range (-40°C ~ 105°C). All substitute parts maintain the same polarization (polar), package type (radial, can - snap-in), and mounting method (through hole). Lead spacing remains constant at 0.394" (10.00 mm) across all qualified substitutes.

Physical dimensions (diameter and height) may vary within the snap-in package family while maintaining mechanical compatibility. Ripple current ratings may differ slightly due to series design variations, but all substitutes meet or exceed the thermal and electrical requirements of the original specification.

Engineering Selection Recommendations

All three parts—LGU2C471MELY, LGN2C471MELZ25, and LGU2C471MELZ—carry active product status from Nichicon and maintain full RoHS3 compliance and REACH unaffected status. Selection between these parts depends on physical space constraints within the application.

The LGU2C471MELY features the smallest diameter (20.00 mm) and largest height (35.00 mm), making it suitable for applications with vertical space availability and limited horizontal footprint. The LGN2C471MELZ25 offers the most compact height (27.00 mm) with a slightly larger diameter (22.00 mm), optimizing for applications requiring minimal vertical clearance. The LGU2C471MELZ provides a mid-range profile with 22.00 mm diameter and 30.00 mm height, balancing dimensional requirements across both axes.

All three parts maintain identical electrical specifications, thermal ratings, and compliance certifications. Selection is driven purely by mechanical fit within the PCB layout and enclosure constraints.

Frequently Asked Questions (FAQ)

Q: Can LGN2C471MELZ25 or LGU2C471MELZ be used as direct replacements for LGU2C471MELY?

A: Yes. All three parts share identical capacitance (470 µF), voltage rating (160 V), tolerance (±20%), thermal lifetime (3000 Hrs @ 105°C), operating temperature range (-40°C ~ 105°C), lead spacing (10.00 mm), and package type (radial, can - snap-in). Substitution is electrically and functionally equivalent. Physical dimensions differ, so verify that the substitute part fits within available PCB space and enclosure height.

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

A: The primary differences are physical dimensions. LGU2C471MELY has a 20.00 mm diameter and 35.00 mm height. LGN2C471MELZ25 has a 22.00 mm diameter and 27.00 mm height. LGU2C471MELZ has a 22.00 mm diameter and 30.00 mm height. Ripple current ratings vary slightly: LGU2C471MELY at 1.34 A @ 120 Hz and 2.01 A @ 50 kHz; LGN2C471MELZ25 at 1.4 A @ 120 Hz and 2.1 A @ 50 kHz; LGU2C471MELZ at 1.55 A @ 120 Hz and 2.325 A @ 50 kHz. All electrical and thermal specifications remain identical.

Q: Are there any compliance or certification differences?

A: No. All three parts are RoHS3 compliant, REACH unaffected, and carry active product status from Nichicon. Compliance and certification status are identical across all substitute options.

Q: How do I determine which substitute part to use?

A: Measure available space on your PCB and within the enclosure. If vertical height is constrained, LGN2C471MELZ25 (27.00 mm) is the most compact option. If horizontal space is limited, LGU2C471MELY (20.00 mm diameter) is the narrowest. LGU2C471MELZ provides a balanced profile between the two. All three are electrically interchangeable.

Q: Can these parts be used in new designs?

A: Yes. All three parts carry active product status and are suitable for new product designs. They are manufactured to current specifications and are in continuous production.
