Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 380LQ331M420J052 is determined by the following criteria:

Mandatory Matching Parameters:

• Capacitance: 330 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Package / Case: Radial, Can - Snap-In (exact match required)
• Lead Spacing: 0.394" (10.00mm) (exact match required)
• Size / Dimension: 0.984" Dia (25.00mm) (exact match required)
• Height - Seated (Max): 2.047" (52.00mm) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Polarization: Polar (exact match required)

Allowable Parameter Variations:

• Voltage - Rated: Substitute parts must equal or exceed 420 V
• Operating Temperature: Substitute parts may extend the upper temperature limit beyond 85°C
• Lifetime @ Temp.: Substitute parts may exceed 2000 hours at rated temperature
• ESR (Equivalent Series Resistance): Variations permitted based on manufacturer specifications
• Ripple Current: Variations permitted based on frequency and manufacturer design

All identified substitute parts maintain full compliance with RoHS3 and REACH requirements, matching the regulatory status of the original component.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Voltage Upgrade with Enhanced Specifications):

The 450MXG330MEFCSN25X50 (Rubycon MXG series) and 450MXH330MEFCSN25X50 (Rubycon MXH series) provide voltage ratings of 450 V, exceeding the original 420 V specification. Both maintain identical physical dimensions and lead spacing. The MXG variant offers extended lifetime of 3000 hours at 105°C, while the MXH variant provides 2000 hours at 105°C. Both are ROHS3 compliant and REACH unaffected.

Secondary Substitute (Extended Temperature Range):

The B43640A5337M000 (EPCOS - TDK B43640 series) provides 450 V rating with extended operating temperature range of -40°C to 105°C, compared to the original -25°C to 85°C. This component features lower ESR at 290 mOhm @ 100Hz and maintains ROHS3 compliance and REACH unaffected status.

Alternative Substitute (High Ripple Current Capability):

The ESMM451VSN331MQ50S (Chemi-Con SMM series) maintains the original operating temperature range of -25°C to 85°C while providing 450 V rating and extended lifetime of 3000 hours at 85°C. This component exhibits higher ripple current capability at high frequencies (3.0316 A @ 100 kHz). Physical dimension is 1.000" Dia (25.40mm), representing a minor dimensional variation from the original 0.984" Dia specification. RoHS compliance is confirmed; REACH status is unaffected.

All substitute parts are Active product status with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the 450MXG330MEFCSN25X50 directly replace the 380LQ331M420J052?

A: Yes. Both components share identical capacitance (330 µF), tolerance (±20%), package type (Radial, Can - Snap-In), lead spacing (10.00mm), and physical dimensions (0.984" Dia × 2.047" height). The 450MXG variant provides higher voltage rating (450 V vs. 420 V) and extended lifetime (3000 Hrs @ 105°C vs. 2000 Hrs @ 85°C). All mounting and electrical interface parameters are compatible.

Q: What is the difference between the Rubycon MXG and MXH series substitutes?

A: Both 450MXG330MEFCSN25X50 and 450MXH330MEFCSN25X50 share identical physical dimensions, lead spacing, voltage rating (450 V), and capacitance (330 µF). The primary difference is lifetime specification: MXG provides 3000 hours at 105°C, while MXH provides 2000 hours at 105°C. Both operate across -25°C to 105°C temperature range.

Q: Does the ESMM451VSN331MQ50S dimensional variation affect compatibility?

A: The ESMM451VSN331MQ50S features a diameter of 1.000" (25.40mm) compared to the original 0.984" (25.00mm). This represents a 0.40mm increase in diameter. Physical board layout and mounting hole spacing must accommodate this dimensional difference. Height and lead spacing remain compatible.

Q: Are all substitute parts RoHS3 compliant?

A: The 450MXG330MEFCSN25X50, 450MXH330MEFCSN25X50, and B43640A5337M000 are explicitly ROHS3 compliant. The ESMM451VSN331MQ50S is RoHS compliant. All four substitute parts maintain REACH unaffected status, matching the regulatory compliance of the original 380LQ331M420J052.

Q: Which substitute offers the lowest ESR?

A: The B43640A5337M000 (EPCOS - TDK) provides the lowest specified ESR at 290 mOhm @ 100Hz. The original 380LQ331M420J052 specifies 603 mOhm @ 120Hz. The ESMM451VSN331MQ50S specifies 1.005 Ohm @ 120Hz. The Rubycon MXG and MXH variants do not provide ESR specifications in the available data.

Q: Can substitutes be used in applications requiring operation below -25°C?

A: The B43640A5337M000 (EPCOS - TDK) extends the lower operating temperature limit to -40°C, compared to -25°C for the original component and other substitutes. If operation below -25°C is required, the B43640A5337M000 is the appropriate selection.

Q: What is the inventory status of substitute parts?
