Equivalent & Substitute Parts for LLS2V331MELA

Part Overview

The LLS2V331MELA is a 330 µF, 350 V aluminum electrolytic capacitor manufactured by Nichicon in the LLS series. This radial, can-style snap-in capacitor is designed for general-purpose applications requiring stable capacitance and extended operational life. The part is currently active in production with ROHS3 compliance and REACH unaffected status. Substitute parts are identified when equivalent electrical ratings, mechanical compatibility, and operational parameters align with the original specification, enabling direct replacement in circuit designs without functional degradation.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LLS2V331MELA are identified based on strict equivalence in the following critical parameters:

• Capacitance value: 330 µF (exact match required)
• Voltage rating: 350 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Mounting type: Through Hole (exact match required)
• Package style: Radial, Can - Snap-In (exact match required)
• Lead spacing: 0.394" (10.00mm) (exact match required)
• Operating temperature range: -25°C ~ 85°C (exact match required)
• Compliance: ROHS3 Compliant, REACH Unaffected (exact match required)

Variations in physical dimensions (diameter and height), ripple current ratings, ESR values, and lifetime specifications do not disqualify a part from substitution provided all critical parameters remain equivalent. These secondary parameters reflect manufacturing tolerances and design variations within the same functional class.

Engineering Selection Recommendations

All three parts—LLS2V331MELA, LLS2V331MELZ, and 380LQ331M350J032—meet the core electrical and mechanical requirements for direct substitution. Selection among these equivalents should be based on the following factors:

LLS2V331MELA and LLS2V331MELZ (Nichicon LLS Series): Both parts share identical electrical specifications and are manufactured by the same supplier. The primary difference is physical form factor: LLS2V331MELA has a 25.00 mm diameter and 37.00 mm height, while LLS2V331MELZ has a 22.00 mm diameter and 47.00 mm height. Choose based on available PCB space and mounting constraints. Both maintain 3000 hours lifetime at 85°C.

380LQ331M350J032 (Cornell Dubilier Electronics 380LQ Series): This part provides equivalent electrical performance with identical lead spacing and voltage rating. The physical dimensions match LLS2V331MELA (25.00 mm diameter, 37.00 mm height), enabling direct mechanical compatibility. The lifetime specification is 2000 hours at 85°C, which is lower than the Nichicon alternatives. This part is suitable for applications where the reduced lifetime does not impact system requirements. All three parts carry ROHS3 compliance and REACH unaffected status, confirming regulatory equivalence.

Frequently Asked Questions (FAQ)

Q: Can LLS2V331MELZ be used as a direct replacement for LLS2V331MELA?

A: Yes. Both parts are electrically identical with matching capacitance (330 µF), voltage rating (350 V), tolerance (±20%), and operating temperature range (-25°C ~ 85°C). The difference is physical size: LLS2V331MELZ is smaller in diameter (22.00 mm vs. 25.00 mm) but taller (47.00 mm vs. 37.00 mm). Verify PCB layout accommodates the height difference before substitution.

Q: Is 380LQ331M350J032 compatible with LLS2V331MELA in all applications?

A: Electrical compatibility is confirmed across all critical parameters. Physical dimensions are identical (25.00 mm diameter, 37.00 mm height), ensuring mechanical fit. The key difference is lifetime: 380LQ331M350J032 is rated for 2000 hours at 85°C compared to 3000 hours for LLS2V331MELA. Applications requiring extended operational life at elevated temperatures should retain the Nichicon part.

Q: Do all three parts have the same lead spacing?

A: Yes. All three parts have 0.394" (10.00 mm) lead spacing, confirming PCB footprint compatibility.

Q: Are there compliance differences between these parts?

A: No. All three parts are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements.

Q: What is the significance of ripple current differences?

A: Ripple current ratings reflect the maximum AC current the capacitor can handle at specified frequencies without exceeding temperature limits. Variations among these parts are within the tolerance band for this capacitor class. Select based on your circuit's actual ripple current requirements at the operating frequency.
