LGU2C152MELB Equivalent & Substitute Parts

Part Overview

The LGU2C152MELB is a 1500 µF, 160 V aluminum electrolytic capacitor manufactured by Nichicon in the LGU series. This radial, can-style snap-in component is rated for 3000 hours at 105°C and is designed for general-purpose applications requiring high capacitance and voltage ratings. The part is currently active in production with ROHS3 compliance and REACH unaffected status. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and design continuity when the primary part becomes unavailable or when alternative mechanical configurations are required.

Substitute Part Grouping Explanation

Substitution eligibility for the LGU2C152MELB is determined by strict equivalence in the following electrical parameters: capacitance (1500 µF), voltage rating (160 V), tolerance (±20%), lifetime rating (3000 Hrs @ 105°C), operating temperature range (-40°C ~ 105°C), and polarization (Polar). All substitute parts must maintain through-hole radial, can-style snap-in packaging with 10.00 mm lead spacing and comply with ROHS3 and REACH requirements.

Mechanical variations in can diameter and height are permitted within the snap-in package family, as these dimensions do not affect electrical performance or core PCB footprint compatibility. Ripple current ratings may vary between substitute parts due to different thermal management characteristics of alternative can geometries, but all substitutes maintain the specified lifetime and temperature ratings.

Engineering Selection Recommendations

Both LGN2C152MELC30 and LGU2C152MELC are electrically equivalent to the LGU2C152MELB and are suitable for direct substitution based on identical capacitance, voltage rating, tolerance, lifetime rating, and operating temperature specifications. All three parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory consistency.

The LGU2C152MELC is the preferred substitute when mechanical form factor is critical, as it maintains the same series designation (LGU) and identical ripple current ratings (2.84 A @ 120 Hz, 4.26 A @ 50 kHz) as the primary part. The LGN2C152MELC30 offers an alternative from the LGN series with slightly lower ripple current capacity (2.5 A @ 120 Hz, 3.75 A @ 50 kHz) but may be selected when space constraints favor a lower profile (1.260" height versus 1.575" for the primary part).

Mechanical compatibility must be verified at the PCB layout level, as can diameter and height variations may affect board-level clearance and thermal management in confined spaces. Lead spacing remains constant at 10.00 mm across all parts, ensuring footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can LGN2C152MELC30 and LGU2C152MELC be used interchangeably with LGU2C152MELB?

A: Yes, both parts are electrically equivalent substitutes. All three parts share identical capacitance (1500 µF), voltage rating (160 V), tolerance (±20%), lifetime (3000 Hrs @ 105°C), and operating temperature range (-40°C ~ 105°C). Lead spacing is constant at 10.00 mm, ensuring PCB footprint compatibility. Mechanical dimensions vary, requiring verification of available board space.

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

A: The primary differences are mechanical. LGU2C152MELC maintains identical ripple current ratings to the primary part (2.84 A @ 120 Hz, 4.26 A @ 50 kHz) and belongs to the same LGU series. LGN2C152MELC30 offers a lower profile (1.260" height) and larger diameter (1.378") but has reduced ripple current capacity (2.5 A @ 120 Hz, 3.75 A @ 50 kHz). Electrical performance and lifetime ratings remain equivalent.

Q: Are there any compliance or certification differences?

A: No. All three parts are ROHS3 compliant and REACH unaffected, with identical regulatory status. Product status is active for all parts, ensuring continued availability and support.

Q: Which substitute should I select for space-constrained applications?

A: LGU2C152MELC offers the lowest profile at 1.181" height while maintaining full ripple current performance. LGN2C152MELC30 provides an intermediate option at 1.260" height. Verify that the selected can diameter (30.00 mm or 35.00 mm) fits within available board clearance.

Q: Do ripple current differences affect circuit performance?

A: Ripple current ratings indicate thermal dissipation capacity under AC stress. LGU2C152MELC and LGU2C152MELB both support 2.84 A @ 120 Hz and 4.26 A @ 50 kHz. LGN2C152MELC30 supports lower ripple currents (2.5 A @ 120 Hz, 3.75 A @ 50 kHz). Select based on actual circuit ripple current requirements; if your application requires ripple current above 2.5 A @ 120 Hz, use LGU2C152MELC or LGU2C152MELB.
