Substitute Part Grouping Explanation

Substitute parts for the LGL2W331MELB35 are grouped based on strict electrical and mechanical parameter alignment:

Parametric Equivalent Category: Parts matching all critical electrical specifications (330 µF capacitance, 450 V rating, ±20% tolerance, -25°C ~ 105°C operating range) and mechanical form factor (radial snap-in, 10.00mm lead spacing, 30.00mm diameter). The LGG2W331MELB35 qualifies as a parametric equivalent despite differing ripple current performance and lifetime rating.

Direct Manufacturer Equivalent Category: Parts meeting identical electrical and mechanical requirements with enhanced performance characteristics. The 450MXK330MEFCFA30X30 from Rubycon provides superior lifetime rating (3000 Hrs @ 105°C versus 2000 Hrs @ 105°C) and higher ripple current capability while maintaining the same package footprint and electrical ratings.

Substitution eligibility is determined by:

• Capacitance value: 330 µF (exact match required)
• Voltage rating: 450 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package type: Radial, Can - Snap-In (exact match required)
• Lead spacing: 10.00mm (exact match required)
• Diameter: 30.00mm (exact match required)
• Mounting type: Through Hole (exact match required)

Parameter Comparison

Engineering Selection Recommendations

LGG2W331MELB35 (Nichicon): This part maintains identical electrical specifications and mechanical form factor to the LGL2W331MELB35. Both are manufactured by Nichicon and carry Active product status with RoHS3 compliance. Selection of this substitute is appropriate when Nichicon series continuity is required or when inventory of the primary part is unavailable.

450MXK330MEFCFA30X30 (Rubycon): This part provides enhanced performance characteristics while maintaining all critical electrical and mechanical parameters. The extended lifetime rating (3000 Hrs @ 105°C) and increased ripple current capability offer superior reliability margins. The reduced height (32.00mm versus 37.00mm) may provide additional board layout flexibility. Both parts are Active status and RoHS3 compliant. Selection of this substitute is appropriate for applications where extended operational life or higher ripple current handling is beneficial.

Frequently Asked Questions (FAQ)

Q: Can LGG2W331MELB35 be used as a direct replacement for LGL2W331MELB35?

A: Yes. Both parts share identical capacitance (330 µF), voltage rating (450 V), tolerance (±20%), operating temperature range (-25°C ~ 105°C), and mechanical package specifications (radial snap-in, 10.00mm lead spacing, 30.00mm diameter). The parts are electrically and mechanically interchangeable.

Q: What are the differences between LGL2W331MELB35 and 450MXK330MEFCFA30X30?

A: The primary differences are manufacturer (Nichicon versus Rubycon), lifetime rating (2000 Hrs versus 3000 Hrs @ 105°C), ripple current performance, and physical height (37.00mm versus 32.00mm). All other electrical and mechanical parameters are identical.

Q: Is the 450MXK330MEFCFA30X30 suitable for applications requiring the LGL2W331MELB35?

A: Yes. The 450MXK330MEFCFA30X30 meets all electrical requirements and maintains the same package footprint and lead spacing. The enhanced lifetime and ripple current ratings provide additional performance margin. The reduced height may require PCB layout verification to ensure clearance compatibility.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All parts listed—LGL2W331MELB35, LGG2W331MELB35, and 450MXK330MEFCFA30X30—are RoHS3 compliant.

Q: Can these parts be used interchangeably in high-ripple-current applications?

A: Ripple current handling differs among the parts. The 450MXK330MEFCFA30X30 provides the highest ripple current capability (2.212 A @ 10 kHz), followed by LGG2W331MELB35 (1.716 A @ 50 kHz), and LGL2W331MELB35 (1.6016 A @ 50 kHz). Selection should be based on application ripple current requirements.
