LLS2V331MELB Equivalent & Substitute Parts

Part Overview

The LLS2V331MELB is a 330 µF, 350 V aluminum electrolytic capacitor in radial, can snap-in package manufactured by Nichicon. This component is classified as Active product status and is designed for general-purpose applications requiring stable capacitance and extended operational life. The part is ROHS3 compliant and suitable for through-hole mounting in industrial and commercial equipment.

Substitute parts are necessary when the primary part experiences supply constraints, inventory limitations, or when design requirements permit operation at higher voltage ratings or extended temperature ranges while maintaining the same capacitance and tolerance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LLS2V331MELB are grouped into two categories based on electrical and mechanical compatibility:

Similar Substitutes (Direct Replacement): Parts LLS2V331MELA and LLS2V331MELZ maintain identical electrical specifications (330 µF, 350 V, ±20% tolerance) and package type (radial, can snap-in). These parts differ only in physical dimensions (diameter and height) while maintaining the same 10.00mm lead spacing. All three Nichicon LLS series parts share identical voltage rating, capacitance, tolerance, operating temperature range, and lifetime rating. Substitution is valid when PCB layout accommodates dimensional variations.

Upgrade Substitutes (Higher Voltage Rating): Parts 450MXK330MEFCFA30X30 (Rubycon) and B43642C9337M000 (EPCOS - TDK Electronics) provide higher voltage ratings (450 V and 400 V respectively) while maintaining 330 µF capacitance and ±20% tolerance. These upgrades extend operational margin and support extended temperature ranges (-25°C ~ 105°C). Physical dimensions match or closely approximate the main part.

Similar Substitute (Alternative Manufacturer): Part 380LQ331M350J032 (Cornell Dubilier Electronics) matches the 330 µF, 350 V, ±20% specification and radial snap-in package. This part operates within the same temperature range and lead spacing but has a reduced lifetime rating (2000 Hrs @ 85°C versus 3000 Hrs @ 85°C).

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Electrical Specifications): LLS2V331MELA and LLS2V331MELZ are valid direct substitutes when PCB layout permits dimensional variation. All three Nichicon LLS series parts maintain identical electrical performance and ROHS3 compliance. Selection between these parts depends solely on available board space and lead spacing requirements (all maintain 10.00mm spacing).

For Upgraded Performance: 450MXK330MEFCFA30X30 (Rubycon MXK series) and B43642C9337M000 (EPCOS B43642 series) provide higher voltage margins (450 V and 400 V respectively) and extended temperature operation to 105°C. These parts are suitable when design specifications permit higher voltage ratings and require enhanced thermal stability. Both maintain ROHS3 compliance and identical physical footprint to the main part.

For Alternative Manufacturer Supply: 380LQ331M350J032 (Cornell Dubilier Electronics 380LQ series) matches the primary part's electrical specifications and package type. This part is suitable when Nichicon supply is constrained. Note the reduced lifetime rating (2000 Hrs @ 85°C versus 3000 Hrs @ 85°C) must be evaluated against application duty cycle requirements.

All substitute parts are ROHS3 compliant and REACH unaffected, meeting regulatory requirements equivalent to the main part.

Frequently Asked Questions (FAQ)

Q: Can LLS2V331MELA or LLS2V331MELZ be used as direct replacements for LLS2V331MELB? A: Yes. These Nichicon LLS series parts share identical capacitance (330 µF), voltage rating (350 V), tolerance (±20%), lead spacing (10.00mm), and lifetime specifications (3000 Hrs @ 85°C). The only differences are physical dimensions (diameter and height). Substitution is valid if PCB layout accommodates the dimensional changes.

Q: What is the advantage of using 450MXK330MEFCFA30X30 or B43642C9337M000? A: Both parts provide higher voltage ratings (450 V and 400 V respectively) compared to the 350 V main part, offering increased operational margin. Both support extended temperature operation to 105°C and maintain 3000-hour lifetime ratings at elevated temperature. These upgrades are suitable for applications requiring enhanced thermal or voltage performance.

Q: Why does 380LQ331M350J032 have a lower lifetime rating? A: The Cornell Dubilier 380LQ series part specifies 2000 Hrs @ 85°C versus 3000 Hrs @ 85°C for the Nichicon LLS series. This difference reflects manufacturer design and testing specifications. Selection depends on application duty cycle and expected service life requirements.

Q: Are all substitute parts through-hole mounted with the same lead spacing? A: Yes. All substitute parts maintain 0.394" (10.00mm) lead spacing and through-hole mounting type. Physical dimensions (diameter and height) vary between parts, requiring PCB layout verification before substitution.

Q: Do all parts meet the same compliance standards? A: Yes. All listed parts are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements.
