Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Mandatory Compatibility Parameters:

• Capacitance: 330 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Lead Spacing: 10.00 mm (exact match required)
• Size / Dimension: 25.00 mm Dia (exact match required)
• Height - Seated (Max): 47.00 mm (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can - Snap-In (exact match required)
• Polarization: Polar (exact match required)

Allowable Variation Parameters:

• Voltage - Rated: May be equal to or higher than 315 V
• Operating Temperature: May extend beyond -25°C ~ 85°C
• Lifetime @ Temp.: May be equal to or exceed 3000 Hrs @ 85°C
• RoHS Status: ROHS3 Compliant (maintained across all substitutes)

All four substitute parts meet these criteria and are therefore electrically and mechanically compatible with the 380LX331M315J452.

LGN2G331MELA45 (Nichicon LGN Series)

This substitute provides 400 V rated voltage with extended operating temperature to 105°C and 3000 Hrs lifetime at 105°C. Product status is Active. RoHS3 compliance is maintained. Selection is appropriate for general-purpose applications with elevated temperature requirements.

LGX2G331MELA45 (Nichicon LGX Series)

This substitute provides 400 V rated voltage with extended operating temperature to 105°C and enhanced lifetime rating of 5000 Hrs @ 105°C. Product status is Active. RoHS3 compliance is maintained. Selection is appropriate for long-life applications or environments with sustained elevated temperature operation.

Frequently Asked Questions (FAQ)

Q: Can the 400MXG330MEFCSN25X45 be used as a direct replacement for the 380LX331M315J452?

A: Yes. Both components share identical capacitance (330 µF), tolerance (±20%), lead spacing (10.00 mm), physical dimensions (25.00 mm Dia × 47.00 mm height), and package configuration (Radial, Can - Snap-In). The 400MXG330MEFCSN25X45 provides higher voltage rating (400 V vs. 315 V) and extended operating temperature range (-25°C ~ 105°C vs. -25°C ~ 85°C), making it suitable for direct substitution in through-hole applications.

Q: What is the difference between the Rubycon and Nichicon substitute options?

A: Both manufacturers provide 400 V rated alternatives. Rubycon 400MXG330MEFCSN25X45 offers 3000 Hrs lifetime at 105°C. Nichicon LGN2G331MELA45 also provides 3000 Hrs at 105°C. Nichicon LGX2G331MELA45 provides extended lifetime of 5000 Hrs at 105°C. Selection depends on application lifetime requirements and thermal environment.

Q: Is the 450USG330MEFCSN25X45 compatible with circuits designed for 315 V operation?

A: Yes. The 450USG330MEFCSN25X45 is rated for 450 V, which exceeds the original 315 V specification. Higher voltage-rated capacitors are electrically compatible with lower voltage circuit designs. Physical dimensions and mounting configuration are identical.

Q: Do all substitute parts maintain RoHS3 compliance?

A: Yes. All four substitute parts are ROHS3 Compliant, matching the compliance status of the original 380LX331M315J452.

Q: Which substitute part offers the longest operational lifetime?

A: The Nichicon LGX2G331MELA45 provides 5000 Hrs @ 105°C, compared to 3000 Hrs @ 105°C for the LGN2G331MELA45 and 400MXG330MEFCSN25X45, and 3000 Hrs @ 85°C for the original 380LX331M315J452 and 450USG330MEFCSN25X45.

Q: Are all substitute parts available in the same snap-in package configuration?

A: Yes. All substitute parts use Radial, Can - Snap-In package configuration with identical lead spacing (10.00 mm) and physical dimensions (25.00 mm Dia × 47.00 mm height), ensuring compatibility with existing PCB layouts and mounting hardware.
