Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LLS2Z331MELY is determined by the following criteria:

Primary Substitution Parameters:

• Capacitance value: 330 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage rating: Equal to or greater than 180 V
• Package type: Radial, Can - Snap-In (exact match required)
• Lead spacing: 0.394" (10.00 mm) (exact match required)
• Physical dimensions: 0.787" Dia × 1.181" Height (exact match required)
• Mounting type: Through Hole (exact match required)
• Polarization: Polar (exact match required)

Secondary Considerations:

• Operating temperature range and lifetime ratings may vary
• Ripple current specifications may differ
• Compliance certifications (RoHS3, REACH) must be maintained

Two substitute parts meet these criteria and are listed below.

Parameter Comparison

Engineering Selection Recommendations

LGU2Z331MELY is a direct functional substitute for the LLS2Z331MELY. Both components share identical electrical ratings (330 µF, ±20%, 180 V), mechanical dimensions, and package configuration. The LGU2Z331MELY operates across an extended temperature range (-40°C ~ 105°C) with a lifetime rating of 3000 hours at 105°C, compared to the LLS2Z331MELY's 3000 hours at 85°C. Ripple current specifications are lower on the LGU2Z331MELY. Both parts maintain RoHS3 compliance and Active product status.

LLS2D331MELY is a substitute with elevated voltage rating. This part maintains the same capacitance (330 µF), tolerance (±20%), and mechanical specifications as the LLS2Z331MELY, but is rated for 200 V instead of 180 V. The LLS2D331MELY operates within the same temperature range (-40°C ~ 85°C) with identical lifetime rating (3000 hours at 85°C). This part is suitable for applications where higher voltage margin is required. RoHS3 compliance and Active product status are maintained.

All three parts are manufactured by Nichicon and carry equivalent regulatory certifications (RoHS3 Compliant, REACH Unaffected).

Frequently Asked Questions (FAQ)

Q: Can LGU2Z331MELY replace LLS2Z331MELY in any application?

A: LGU2Z331MELY meets all substitution criteria: identical capacitance (330 µF), tolerance (±20%), voltage rating (180 V), and physical dimensions. The extended operating temperature range (-40°C ~ 105°C) and higher temperature lifetime rating (3000 Hrs @ 105°C) make it suitable for applications operating at elevated temperatures. Ripple current specifications differ; verify application requirements before selection.

Q: When should LLS2D331MELY be selected instead of LLS2Z331MELY?

A: LLS2D331MELY is selected when circuit design requires a 200 V rated capacitor instead of 180 V. All other electrical and mechanical parameters remain equivalent. This part provides additional voltage margin for the same capacitance and tolerance values.

Q: Are all three parts mechanically interchangeable?

A: Yes. All three parts share identical lead spacing (0.394" / 10.00 mm), case diameter (0.787" / 20.00 mm), and seated height (1.181" / 30.00 mm). All use radial, can snap-in packages with through-hole mounting. PCB footprints and mounting hardware are compatible.

Q: Do all substitute parts maintain the same compliance certifications?

A: Yes. LLS2Z331MELY, LGU2Z331MELY, and LLS2D331MELY are all RoHS3 Compliant and REACH Unaffected. All parts carry Active product status from Nichicon.

Q: What is the difference in ripple current handling between these parts?

A: LLS2Z331MELY handles the highest ripple current (1.77 A @ 120 Hz, 2.655 A @ 50 kHz). LLS2D331MELY handles 1.56 A @ 120 Hz and 2.34 A @ 50 kHz. LGU2Z331MELY handles 1.2 A @ 120 Hz and 1.8 A @ 50 kHz. Select based on circuit ripple current requirements.
