Engineering Selection Recommendations

Direct Substitution (380LQ331M350J032): The 380LQ331M350J032 is a direct electrical equivalent suitable for applications where the 380LX331M350J052 is unavailable. Both parts maintain identical capacitance (330 µF), voltage rating (350 V), and tolerance (±20%). The 380LQ series exhibits slightly higher ESR (603 mOhm vs. 500 mOhm) and reduced lifetime (2000 Hrs @ 85°C vs. 3000 Hrs @ 85°C). This part is ROHS3 compliant and Active product status. Board-level compatibility is confirmed through matching lead spacing (10.00 mm), diameter (25.00 mm), and radial snap-in package configuration. The reduced height (37.00 mm vs. 52.00 mm) may provide space advantages in compact designs.

Upgraded Substitution (450MXG330MEFCSN25X50): The 450MXG330MEFCSN25X50 (Rubycon MXG series) is an upgraded substitute offering higher voltage rating (450 V vs. 350 V) while maintaining 330 µF capacitance and ±20% tolerance. This part is suitable for applications requiring increased voltage margin or operation in higher voltage environments. The extended operating temperature range (-25°C to 105°C) and lifetime rating (3000 Hrs @ 105°C) provide enhanced thermal performance. ROHS3 compliance and Active product status are confirmed. Physical compatibility is maintained through identical lead spacing (10.00 mm), diameter (25.00 mm), height (52.00 mm), and radial snap-in package type.

Upgraded Substitution (ESMM451VSN331MQ50S): The ESMM451VSN331MQ50S (Chemi-Con SMM series) is an upgraded substitute with 450 V voltage rating and 330 µF capacitance. This part features the lowest ESR among all listed substitutes (1.005 Ohm @ 120 Hz), resulting in superior ripple current handling (2.12 A @ 120 Hz). The 3000-hour lifetime at 85°C matches the main part specification. RoHS compliance and Active product status are confirmed. Physical compatibility is maintained with identical lead spacing (10.00 mm) and radial snap-in package type. Diameter is 25.40 mm (0.40 mm larger than main part) and height is 52.00 mm, requiring verification of board layout clearance in space-constrained applications.

Frequently Asked Questions (FAQ)

Q1: Can the 380LQ331M350J032 be used as a direct replacement for the 380LX331M350J052?

A: Yes. Both parts share identical capacitance (330 µF), voltage rating (350 V), and tolerance (±20%). Lead spacing (10.00 mm), diameter (25.00 mm), and radial snap-in package configuration are identical, enabling direct board-level substitution. The 380LQ series exhibits higher ESR (603 mOhm vs. 500 mOhm) and reduced lifetime (2000 Hrs @ 85°C vs. 3000 Hrs @ 85°C), which may impact performance in applications with stringent ripple current or thermal cycling requirements.

Q2: What are the advantages of using 450 V rated substitutes instead of the 350 V main part?

A: The 450MXG330MEFCSN25X50 and ESMM451VSN331MQ50S provide higher voltage margin, allowing operation in circuits with voltage transients or design headroom requirements. The 450MXG330MEFCSN25X50 extends the operating temperature range to 105°C with corresponding lifetime rating (3000 Hrs @ 105°C), suitable for high-temperature environments. The ESMM451VSN331MQ50S offers superior ESR performance (1.005 Ohm), enabling higher ripple current handling (2.12 A @ 120 Hz).

Q3: Are there physical compatibility concerns when substituting the ESMM451VSN331MQ50S?

A: The ESMM451VSN331MQ50S maintains identical lead spacing (10.00 mm) and height (52.00 mm) as the main part. The diameter is 25.40 mm, which is 0.40 mm larger than the 25.00 mm main part specification. Board layout clearance must be verified in space-constrained applications to ensure the slightly larger diameter does not interfere with adjacent components or PCB traces.

Q4: Which substitute part offers the best ESR performance?

A: The ESMM451VSN331MQ50S provides the lowest ESR at 1.005 Ohm @ 120 Hz, compared to 500 mOhm for the main part and 603 mOhm for the 380LQ331M350J032. Lower ESR reduces heat generation and improves ripple current handling capability, making this part suitable for high-current or thermally demanding applications.

Q5: Are all substitute parts RoHS compliant?

A: Yes. The 380LQ331M350J032 and 450MXG330MEFCSN25X50 are ROHS3 compliant. The ESMM451VSN331MQ50S is RoHS compliant. All parts meet environmental compliance requirements for commercial and industrial applications.

Q6: What is the impact of the 380LQ331M350J032 having a shorter height (37.00 mm vs. 52.00 mm)?

A: The reduced height of the 380LQ331M350J032 provides space advantages in compact or vertically constrained PCB designs. However, the reduced height may correlate with different thermal characteristics or ripple current ratings. Electrical performance parameters must be verified against application requirements before substitution.

Q7: Can the 450 V rated parts be used in 350 V circuits?

A: Yes. The 450MXG330MEFCSN25X50 and ESMM451VSN331MQ50S are rated for 450 V operation and are therefore suitable for circuits designed for 350 V operation. Higher voltage rating provides additional safety margin and does not degrade performance in lower voltage applications.
