Equivalent & Substitute Parts for LLS2D331MELZ

Part Overview

The LLS2D331MELZ is a 330 µF, 200 V aluminum electrolytic capacitor in a radial, can snap-in package manufactured by Nichicon. This component is rated for 3000 hours at 85°C and is designed for general-purpose applications requiring through-hole mounting. The part is currently active in production with ROHS3 compliance.

Substitute parts are necessary when the original LLS2D331MELZ is unavailable due to inventory constraints, supply chain disruptions, or when design requirements permit operation at higher temperature ratings or voltage specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the LLS2D331MELZ is determined by the following criteria:

Direct Substitutes maintain identical electrical specifications: 330 µF capacitance, 200 V voltage rating, ±20% tolerance, and through-hole radial snap-in package with 10.00mm lead spacing. These parts are mechanically and electrically interchangeable.

Similar Substitutes share the same capacitance and voltage rating but may differ in physical dimensions (diameter or height), operating temperature range, or ripple current ratings. These parts are functionally equivalent but require verification of mechanical fit within the PCB layout.

Upgrade Substitutes provide enhanced performance characteristics, such as higher temperature ratings (105°C vs. 85°C) or different manufacturers, while maintaining the same electrical specifications and package footprint.

Parametric Equivalents meet the core electrical requirements but may have different ESR values, ripple current specifications, or product status classifications.

Engineering Selection Recommendations

LGW2D331MELZ25 (Nichicon) is the preferred direct substitute. It maintains identical physical dimensions (22.00mm diameter, 25.00mm height) and lead spacing as the LLS2D331MELZ while providing enhanced thermal performance with a 105°C temperature rating versus 85°C. This part is active in production with ROHS3 compliance and offers superior ripple current handling (1.97 A @ 120 Hz vs. 1.51 A @ 120 Hz).

381LR331M200H012 (Cornell Dubilier Electronics) is an upgrade substitute from an alternative manufacturer. It matches the physical footprint and electrical specifications of the LLS2D331MELZ while offering the same 105°C temperature rating as the LGW2D331MELZ25. This part is active in production with ROHS3 compliance.

SLPX331M200A1P3 (Cornell Dubilier Electronics) is a parametric equivalent with identical electrical specifications and physical dimensions to the LLS2D331MELZ. This part is active in production and suitable for direct replacement when Nichicon parts are unavailable.

LLS2D331MELY (Nichicon) is a similar substitute with identical electrical specifications but different physical dimensions (20.00mm diameter, 30.00mm height). This part requires PCB layout verification to confirm mechanical fit.

LLS2E331MELZ (Nichicon) operates at 250 V, exceeding the 200 V requirement of the LLS2D331MELZ. This part is suitable only when higher voltage margin is required by design specifications.

SLPX331M200A3P3 (Cornell Dubilier Electronics) is classified as obsolete and should be avoided for new designs or long-term supply chain planning.

Frequently Asked Questions (FAQ)

Q: Can LGW2D331MELZ25 be used as a direct replacement for LLS2D331MELZ?

A: Yes. Both parts share identical capacitance (330 µF), voltage rating (200 V), tolerance (±20%), lead spacing (10.00mm), and physical dimensions (22.00mm diameter, 25.00mm height). The LGW2D331MELZ25 provides enhanced thermal performance with a 105°C operating temperature versus 85°C.

Q: What is the difference between LLS2D331MELY and LLS2D331MELZ?

A: Both parts are manufactured by Nichicon with identical electrical specifications (330 µF, 200 V, ±20%, 3000 Hrs @ 85°C). The primary difference is physical size: LLS2D331MELY has a 20.00mm diameter and 30.00mm height, while LLS2D331MELZ has a 22.00mm diameter and 25.00mm height. Mechanical fit within the PCB layout must be verified before substitution.

Q: Can LLS2E331MELZ replace LLS2D331MELZ?

A: LLS2E331MELZ has a higher voltage rating (250 V vs. 200 V) and different physical dimensions (30.00mm height vs. 25.00mm height). It is electrically compatible but requires verification of mechanical fit and may introduce unnecessary cost if the higher voltage rating is not required by design specifications.

Q: Why is SLPX331M200A3P3 listed as obsolete?

A: SLPX331M200A3P3 is classified as obsolete by the manufacturer. While it meets the electrical specifications of the LLS2D331MELZ, it should not be selected for new designs or applications requiring long-term supply chain availability.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant and suitable for applications requiring RoHS compliance.

Q: What is the lead spacing requirement for the LLS2D331MELZ?
