Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LLS2G820MELZ is determined by the following criteria:

Fixed Parameters (Non-Negotiable):

• Capacitance: 82 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Lead Spacing: 0.394" (10.00mm) (exact match required)
• Size / Dimension: 0.866" Dia (22.00mm) (exact match required)
• Height - Seated (Max): 0.984" (25.00mm) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can - Snap-In (exact match required)

Variable Parameters (Substitution Allowed):

• Voltage - Rated: 400 V or higher (uprating permitted)
• Lifetime @ Temperature: 3000 Hrs or greater at specified temperature
• Operating Temperature Range: -25°C minimum; upper limit 85°C or higher
• Manufacturer: Nichicon or equivalent qualified manufacturer
• ESR and Ripple Current: Variations acceptable within application requirements

Three substitute parts meet these criteria with variations in voltage rating and thermal performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

LLS2G820MELZ (Original Part) Use when 400 V rating and 85°C thermal specification are sufficient for the application. All substitute parts provide equal or superior electrical performance and compliance characteristics.

LGUW6820MELZ (Nichicon LGU Series) Select this substitute when higher operating temperature capability is required. This part provides 420 V rated voltage and 3000 Hrs lifetime at 105°C, extending thermal margin beyond the original specification. Nichicon manufacturer continuity is maintained. ROHS3 compliance confirmed.

LLS2W820MELZ (Nichicon LLS Series) Select this substitute when higher voltage rating is the primary requirement. This part provides 450 V rated voltage while maintaining the same Nichicon LLS series lineage as the original. Operating temperature remains -25°C ~ 85°C. ROHS3 compliance confirmed.

381LR820M400H012 (Cornell Dubilier Electronics) Select this substitute when manufacturer diversification is required or when extended thermal performance at 105°C is needed with 400 V rating. This part maintains the same voltage specification as the original while providing superior thermal lifetime. Cornell Dubilier Electronics is a qualified alternative manufacturer. ROHS3 compliance confirmed.

All substitute parts maintain identical mechanical compatibility, lead spacing, and snap-in package configuration. Selection should be based on application voltage requirements and thermal operating environment.

Frequently Asked Questions (FAQ)

Q: Can LGUW6820MELZ replace LLS2G820MELZ in a 400 V circuit? A: Yes. LGUW6820MELZ is rated for 420 V, which exceeds the 400 V requirement. The higher voltage rating provides additional safety margin. All mechanical and electrical parameters remain compatible.

Q: What is the difference between LLS2W820MELZ and the original LLS2G820MELZ? A: The primary difference is voltage rating: LLS2W820MELZ is rated 450 V versus 400 V for LLS2G820MELZ. Both maintain identical capacitance, tolerance, temperature range, and physical dimensions. The higher voltage rating accommodates applications with greater voltage stress.

Q: Can I use 381LR820M400H012 (Cornell Dubilier) in place of the Nichicon original? A: Yes. The Cornell Dubilier part maintains identical voltage, capacitance, tolerance, and physical dimensions. It provides superior thermal performance at 105°C versus 85°C. Both manufacturers meet ROHS3 compliance requirements.

Q: Are all substitute parts mechanically identical to the original? A: Yes. All substitute parts share identical lead spacing (10.00mm), diameter (22.00mm), height (25.00mm), and radial snap-in package configuration. Direct mechanical substitution is supported without PCB redesign.

Q: Which substitute should I choose for a high-temperature application? A: Both LGUW6820MELZ and 381LR820M400H012 support -25°C ~ 105°C operating range with 3000 Hrs lifetime at 105°C. Choose based on voltage requirement: LGUW6820MELZ for 420 V circuits or 381LR820M400H012 for 400 V circuits requiring thermal margin.

Q: Do all parts meet environmental compliance standards? A: Yes. All parts listed are ROHS3 compliant and REACH unaffected. Moisture sensitivity level is not applicable for all parts. ECCN classification is EAR99 for all parts.
