Equivalent & Substitute Parts for LLS1H332MELZ

Part Overview

The Nichicon LLS1H332MELZ is a 3300 µF, 50 V aluminum electrolytic capacitor in radial, can snap-in package format, rated for 3000 hours at 85°C. This component is designed for general-purpose applications requiring stable capacitance and reliable performance across the operating temperature range of -40°C to 85°C. The part is currently active and in stock with ROHS3 compliance.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when supply chain optimization is required, or when design flexibility allows for alternative manufacturers meeting identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LLS1H332MELZ is determined by strict alignment of the following parameters:

• Capacitance: 3300 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage Rating: 50 V (exact match required)
• Lifetime: 3000 Hrs @ 85°C (exact match required)
• Operating Temperature: -40°C ~ 85°C (exact match required)
• Polarization: Polar (exact match required)
• Lead Spacing: 0.394" (10.00mm) (exact match required)
• Package Type: Radial, Can - Snap-In (exact match required)
• Mounting Type: Through Hole (exact match required)

All substitute parts listed below meet these core electrical and mechanical requirements. Variations in physical dimensions (diameter and height) and ESR characteristics are permitted within the scope of snap-in can package design, provided all primary parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are active products with ROHS3 compliance, matching the regulatory and compliance status of the primary LLS1H332MELZ component. Selection among these alternatives should be based on:

Direct Equivalents (Identical Physical Dimensions):

• SLPX332M050A3P3 and 380LX332M050H022 maintain the same 0.866" diameter and 1.260" height as the LLS1H332MELZ, providing direct mechanical compatibility with existing PCB layouts and mechanical assemblies.

Compact Alternatives (Reduced Height):

• 380LX332M050J012 and SLPX332M050C1P3 offer reduced height profiles (1.063" and 0.984" respectively), suitable for space-constrained applications where vertical clearance is limited. The 380LX332M050J012 also features a larger diameter (0.984") while maintaining the same lead spacing.

All substitute parts maintain identical electrical specifications (capacitance, voltage rating, tolerance, operating temperature range, and lifetime rating) and are suitable for direct replacement in general-purpose applications.

Frequently Asked Questions (FAQ)

Q: Can SLPX332M050A3P3 be used as a direct replacement for LLS1H332MELZ?

A: Yes. SLPX332M050A3P3 is a direct equivalent with identical capacitance (3300 µF), voltage rating (50 V), tolerance (±20%), lifetime (3000 Hrs @ 85°C), operating temperature range (-40°C ~ 85°C), lead spacing (0.394"), and physical dimensions (0.866" diameter, 1.260" height). It is suitable for direct PCB substitution.

Q: What is the difference between the 380LX series and SLPX series substitutes?

A: Both series are manufactured by Cornell Dubilier Electronics and meet all core electrical parameters. The primary differences are ESR characteristics (380LX series: 100 mOhm @ 120Hz; SLPX series: 141 mOhm @ 120Hz) and physical dimensions. The 380LX332M050J012 features a larger diameter (0.984") with reduced height (1.063"), while 380LX332M050H022 maintains the original diameter (0.866") with original height (1.260").

Q: Can I use 380LX332M050J012 if my PCB has limited vertical space?

A: Yes. The 380LX332M050J012 has a height of 1.063", which is 0.197" shorter than the LLS1H332MELZ (1.260"). However, verify that the larger diameter (0.984" vs. 0.866") does not conflict with horizontal space constraints or adjacent component placement on your PCB.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All four substitute parts (SLPX332M050A3P3, 380LX332M050J012, SLPX332M050C1P3, and 380LX332M050H022) are ROHS3 compliant, matching the compliance status of the LLS1H332MELZ.

Q: What is the lead spacing requirement, and do all substitutes meet it?

A: The required lead spacing is 0.394" (10.00mm). All substitute parts maintain this identical lead spacing, ensuring compatibility with existing PCB footprints and through-hole mounting patterns.

Q: Can I substitute based on ESR alone?

A: No. ESR is a secondary characteristic. Substitution must be based on the core electrical parameters: capacitance, voltage rating, tolerance, lifetime rating, and operating temperature range. All listed substitutes meet these primary requirements. ESR variations (100 mOhm to 141 mOhm @ 120Hz) are within acceptable ranges for general-purpose applications but should be evaluated if your circuit has specific ripple current or thermal dissipation requirements.
