Substitute Part Grouping Explanation

Substitution of the LGX2G331MELB35 is based on strict equivalence of the following parameters:

• Capacitance value: 330 µF (exact match required)
• Voltage rating: 400 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime specification: 5000 Hrs @ 105°C (exact match required)
• Package type: Radial, Can - Snap-In (exact match required)
• Lead spacing: 0.394" (10.00 mm) (exact match required)
• Physical dimensions: 1.181" Dia × 1.457" Height (exact match required)
• Mounting type: Through Hole (exact match required)
• Polarization: Polar (exact match required)

The B43644B9337M000 from EPCOS - TDK Electronics meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the LGX2G331MELB35 and B43644B9337M000 are active production parts with ROHS3 compliance and REACH unaffected status. The B43644B9337M000 provides an extended lower operating temperature limit of -40°C compared to -25°C for the LGX2G331MELB35, offering broader thermal range coverage. Both parts meet identical electrical and mechanical specifications for capacitance, voltage rating, tolerance, lifetime, and physical dimensions. Selection between these parts should be based on availability, supply chain requirements, and application-specific temperature operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the B43644B9337M000 be used as a direct replacement for the LGX2G331MELB35?

A: Yes. Both parts share identical capacitance (330 µF), voltage rating (400 V), tolerance (±20%), lifetime (5000 Hrs @ 105°C), lead spacing (10.00 mm), physical dimensions (1.181" Dia × 1.457" Height), and package type (Radial, Can - Snap-In). They are mechanically and electrically interchangeable for through-hole PCB applications.

Q: What is the difference in operating temperature range?

A: The LGX2G331MELB35 operates from -25°C to 105°C, while the B43644B9337M000 operates from -40°C to 105°C. The EPCOS part supports a wider lower temperature range, making it suitable for applications requiring extended cold-temperature performance.

Q: Are both parts RoHS compliant?

A: Yes. Both the LGX2G331MELB35 and B43644B9337M000 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Do the ripple current specifications differ?

A: The ripple current values are measured at different frequencies. The LGX2G331MELB35 specifies 1.43 A @ 120 Hz, while the B43644B9337M000 specifies 1.49 A @ 100 Hz. Both values are comparable and suitable for general-purpose applications.

Q: What is the snap-in mounting configuration?

A: Both parts use radial, can-style snap-in packaging with through-hole mounting. The snap-in design allows for quick mechanical fastening to the PCB without additional hardware, with lead spacing of 10.00 mm between terminals.
