Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Nichicon LLS2V221MELZ is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 220 µF (exact match required)
• Voltage Rating: 350 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package Configuration: Radial, Can - Snap-In (exact match required)
• Lead Spacing: 10.00 mm (exact match required)
• Physical Dimensions: 22.00 mm diameter, 37.00 mm height (exact match required)
• Mounting Type: Through Hole (exact match required)
• Polarization: Polar (exact match required)

The identified substitute part, Nichicon LGN2V221MELZ35, meets all critical electrical and mechanical parameters. The primary distinction is the extended operating temperature range (-25°C ~ 105°C versus -25°C ~ 85°C) and corresponding lifetime specification (3000 Hrs @ 105°C versus 3000 Hrs @ 85°C), which represents an enhancement rather than a limitation for direct substitution in applications operating within the original thermal envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the Nichicon LLS2V221MELZ and LGN2V221MELZ35 are active production parts with full RoHS3 compliance and REACH unaffected status, ensuring regulatory compliance for current and future applications. The LGN2V221MELZ35 substitute provides identical electrical performance within the original operating temperature specification (-25°C ~ 85°C) while offering extended thermal capability to 105°C. This extended thermal rating does not introduce incompatibility with existing designs and may provide additional operational margin in thermally demanding environments. Both parts are manufactured by Nichicon and maintain identical mechanical interfaces, lead spacing, and package footprints, ensuring direct board-level compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can the LGN2V221MELZ35 be used as a direct replacement for the LLS2V221MELZ in existing designs?

A: Yes. Both parts share identical capacitance (220 µF), voltage rating (350 V), tolerance (±20%), physical dimensions (22.00 mm diameter, 37.00 mm height), lead spacing (10.00 mm), and package configuration (Radial, Can - Snap-In). The LGN2V221MELZ35 features an extended operating temperature range (-25°C ~ 105°C) compared to the LLS2V221MELZ (-25°C ~ 85°C), which represents a performance enhancement for applications operating within the original thermal envelope.

Q: What is the primary difference between these two parts?

A: The primary difference is the thermal specification. The LGN2V221MELZ35 is rated for 3000 hours at 105°C, while the LLS2V221MELZ is rated for 3000 hours at 85°C. Both parts maintain identical performance at the original operating temperature range of -25°C ~ 85°C.

Q: Are there any ripple current differences between these parts?

A: Yes. The LLS2V221MELZ specifies 1.47 A @ 120 Hz and 2.1021 A @ 50 kHz, while the LGN2V221MELZ35 specifies 1.0 A @ 120 Hz and 1.43 A @ 50 kHz. Applications requiring the higher ripple current capability of the LLS2V221MELZ should not substitute with the LGN2V221MELZ35.

Q: Do both parts have the same regulatory compliance?

A: Yes. Both the LLS2V221MELZ and LGN2V221MELZ35 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

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

A: Yes. Both parts have identical through-hole mounting characteristics, lead spacing (10.00 mm), and snap-in package configuration, allowing direct board-level substitution without PCB redesign or rework.
