LGU2A152MELZ Equivalent & Substitute Parts

Part Overview

The LGU2A152MELZ is a 1500 µF, 100 V aluminum electrolytic capacitor in radial, can snap-in package manufactured by Nichicon. This component is rated for 3000 hours at 105°C and is designed for general-purpose applications requiring through-hole mounting. The part is active and ROHS3 compliant.

Substitute Part Grouping Explanation

Substitution eligibility for the LGU2A152MELZ is determined by the following criteria:

Capacitance: 1500 µF (exact match required)
Voltage Rating: 100 V (exact match required)
Tolerance: ±20% (exact match required)
Package Type: Radial, Can - Snap-In (exact match required)
Mounting Type: Through Hole (exact match required)
Lead Spacing: 10.00 mm (exact match required)
Operating Temperature Range: -40°C ~ 105°C (exact match required)
Polarization: Polar (exact match required)

The two identified substitutes, LGY2A152MELA40 and LGY2A152MELB30, meet all electrical and mechanical compatibility requirements. Both parts are from the Nichicon LGY series and offer extended lifetime ratings of 5000 hours at 105°C compared to the LGU series baseline of 3000 hours. Physical dimensions vary between substitute options to accommodate different board layout constraints.

Engineering Selection Recommendations

All three parts—LGU2A152MELZ, LGY2A152MELA40, and LGY2A152MELB30—are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component deployment.

Selection between these parts depends on physical space constraints and lifetime requirements:

LGU2A152MELZ: Compact diameter (22.00 mm) with maximum height of 47.00 mm. Suitable for applications where board space is limited in the radial direction but vertical clearance is available. Rated for 3000 hours at 105°C.
LGY2A152MELA40: Intermediate diameter (25.00 mm) with reduced height (42.00 mm). Provides extended 5000-hour lifetime rating at 105°C. Appropriate for designs requiring improved reliability with moderate space constraints.
LGY2A152MELB30: Largest diameter (30.00 mm) with shortest height (32.00 mm). Offers extended 5000-hour lifetime rating at 105°C. Optimal for applications with limited vertical clearance but adequate radial board space.

All substitutes maintain identical electrical specifications: 1500 µF capacitance, 100 V voltage rating, ±20% tolerance, and -40°C to 105°C operating range. Lead spacing remains constant at 10.00 mm across all variants.

Frequently Asked Questions (FAQ)

Q: Can LGY2A152MELA40 or LGY2A152MELB30 be used as direct replacements for LGU2A152MELZ?

A: Yes, both LGY series parts are electrically and mechanically compatible substitutes. All three parts share identical capacitance (1500 µF), voltage rating (100 V), tolerance (±20%), lead spacing (10.00 mm), and operating temperature range (-40°C ~ 105°C). Physical dimensions differ, requiring verification of available board space.

Q: What is the primary difference between the LGU and LGY series?

A: The LGY series offers extended lifetime ratings of 5000 hours at 105°C compared to the LGU series baseline of 3000 hours at 105°C. Electrical performance remains equivalent across both series for this capacitance and voltage rating.

Q: How do the physical dimensions affect component selection?

A: The three parts have different form factors due to varying diameter and height specifications. LGU2A152MELZ (22.00 mm diameter, 47.00 mm height) is most compact radially but tallest. LGY2A152MELA40 (25.00 mm diameter, 42.00 mm height) provides mid-range dimensions. LGY2A152MELB30 (30.00 mm diameter, 32.00 mm height) is widest but shortest. Board layout constraints determine which variant is appropriate.

Q: Are all three parts RoHS and REACH compliant?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component use.

Q: Do the substitute parts have different ripple current ratings?

A: Yes. LGU2A152MELZ is rated for 1.99 A @ 120 Hz and 2.2885 A @ 50 kHz. Both LGY substitutes are rated for 1.8 A @ 120 Hz and 2.07 A @ 50 kHz. Verify ripple current requirements for your specific application before substitution.

Q: Can these parts be used interchangeably in high-frequency applications?

A: All three parts are rated for high-frequency ripple current at 50 kHz. However, the LGU2A152MELZ has a higher ripple current specification at high frequency (2.2885 A vs. 2.07 A). Applications with demanding ripple current requirements should confirm the LGY substitutes meet performance specifications.
