Nichicon LLS2Z471MELZ Equivalent & Substitute Parts

Part Overview

The Nichicon LLS2Z471MELZ is a 470 µF, 180 V aluminum electrolytic capacitor in radial, can snap-in package configuration. This component is designed for general-purpose applications requiring polarized energy storage with a rated lifetime of 3000 hours at 85°C. The part is currently active in production with ROHS3 compliance and REACH unaffected status. Substitute parts are identified when design requirements permit voltage rating upgrades or enhanced thermal performance characteristics while maintaining identical capacitance, tolerance, and mechanical form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LLS2Z471MELZ are qualified based on the following criteria:

Mandatory Matching Parameters:

• Capacitance: 470 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Package / Case: Radial, Can - Snap-In (exact match required)
• Mounting Type: Through Hole (exact match required)
• Lead Spacing: 0.394" (10.00mm) (exact match required)
• Physical Dimensions: 0.866" Dia × 1.181" Height (exact match required)

Allowable Variation Parameters:

• Voltage - Rated: May increase from 180 V to 200 V (backward compatible; higher voltage rating provides design margin)
• Operating Temperature Range: May extend from -40°C ~ 85°C to -40°C ~ 105°C (enhanced thermal capability)
• Lifetime @ Temperature: May vary based on temperature rating (3000 Hrs @ 85°C or 3000 Hrs @ 105°C)
• Ripple Current Ratings: May increase with voltage or temperature rating changes

Two substitute parts meet these criteria: LLS2D471MELZ (same series, upgraded voltage) and LGW2D471MELZ30 (different series, upgraded voltage and temperature).

Parameter Comparison

Engineering Selection Recommendations

LLS2D471MELZ Selection Criteria: This substitute maintains the LLS series designation and identical thermal performance (3000 Hrs @ 85°C). The voltage rating upgrade from 180 V to 200 V provides increased design margin for applications where the original 180 V specification permits higher voltage operation. Physical footprint and mounting characteristics are identical, enabling direct board-level substitution. ROHS3 compliance and active product status confirm ongoing manufacturing support.

LGW2D471MELZ30 Selection Criteria: This substitute represents a series upgrade within the Nichicon portfolio, offering both voltage rating increase (180 V to 200 V) and enhanced thermal performance (operating range extended to 105°C, lifetime rated at 3000 Hrs @ 105°C). Ripple current handling increases across both frequency bands. Physical dimensions and mounting type remain identical. ROHS3 compliance and active product status are maintained. This option is suitable for applications requiring extended temperature operation or higher ripple current dissipation.

Both substitutes are electrically and mechanically compatible with the LLS2Z471MELZ in applications where the design permits voltage rating increases and thermal performance enhancements.

Frequently Asked Questions (FAQ)

Q: Can LLS2D471MELZ or LGW2D471MELZ30 be used as direct replacements for LLS2Z471MELZ?

A: Yes, both parts are direct substitutes from a mechanical and electrical standpoint. The 470 µF capacitance, ±20% tolerance, radial snap-in package, and through-hole mounting are identical. The voltage rating increase from 180 V to 200 V is backward compatible in applications designed for 180 V operation.

Q: What is the difference between LLS2D471MELZ and LGW2D471MELZ30?

A: Both parts upgrade the voltage rating to 200 V. The primary difference is thermal performance: LLS2D471MELZ maintains the 85°C maximum operating temperature of the original part, while LGW2D471MELZ30 extends the operating range to 105°C and is rated for 3000 hours at 105°C. The LGW series also provides higher ripple current ratings.

Q: Are there any physical dimension differences between these parts?

A: No. All three parts share identical physical dimensions: 0.866" diameter, 1.181" maximum seated height, 0.394" lead spacing, and radial snap-in package configuration. Board layout and mechanical clearances require no modification.

Q: Do all parts meet the same compliance standards?

A: Yes. LLS2Z471MELZ, LLS2D471MELZ, and LGW2D471MELZ30 are all ROHS3 compliant and REACH unaffected. All parts carry active product status from Nichicon.

Q: Which substitute should be selected for high-temperature applications?

A: LGW2D471MELZ30 is the appropriate choice for applications requiring operation above 85°C, as it is rated for continuous operation up to 105°C with a 3000-hour lifetime at that temperature.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. The identical lead spacing (10.00mm), package type (radial snap-in), and mounting method (through-hole) allow these parts to be used interchangeably without PCB redesign or assembly process modification.
