LLS2D331MELY Equivalent & Substitute Parts

Part Overview

The LLS2D331MELY is a 330 µF, 200 V aluminum electrolytic capacitor in radial, can snap-in package manufactured by Nichicon. This component is classified as Active and designed for general-purpose applications requiring stable capacitance over extended operational life. The part operates across a temperature range of -40°C to 85°C with a rated lifetime of 3000 hours at 85°C.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when design flexibility is required across manufacturing sources, or when operational parameters allow for higher voltage ratings or alternative physical dimensions within the same functional category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LLS2D331MELY is determined by the following criteria:

Primary Substitution Parameters:

• Capacitance: 330 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage Rating: 200 V minimum (equal or higher acceptable)
• Polarization: Polar (exact match required)
• Package Type: Radial, Can - Snap-In (exact match required)
• Mounting Type: Through Hole (exact match required)
• Lead Spacing: 0.394" (10.00 mm) (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Lifetime @ Temperature: 3000 Hrs @ 85°C (exact match required)

Secondary Considerations:

• Physical dimensions (diameter and height) may vary within the snap-in package specification
• Ripple current ratings may vary between manufacturers
• ESR values may differ based on manufacturer design

Parts meeting all primary substitution parameters are classified as direct equivalents. The LLS2D331MELZ (Nichicon), SLPX331M200A1P3 (CDE), and SLPX331M200A3P3 (CDE) meet these criteria. The LLS2E331MELY (Nichicon) qualifies as a substitute with higher voltage rating (250 V vs. 200 V), which provides additional design margin in applications where the circuit voltage does not exceed 200 V.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Preferred for New Designs):

LLS2D331MELZ and SLPX331M200A1P3 are functionally equivalent to the LLS2D331MELY. Both maintain Active product status and ROHS3 compliance. The LLS2D331MELZ offers the advantage of identical manufacturer sourcing (Nichicon). The SLPX331M200A1P3 provides cross-manufacturer availability through Cornell Dubilier Electronics with higher inventory levels (3431 units in stock).

Higher Voltage Alternative:

LLS2E331MELY is suitable for applications where circuit design permits operation at 250 V rating. This part provides additional voltage margin and is manufactured by Nichicon with Active status. Physical dimensions differ (height 1.378" vs. 1.181"), requiring verification of PCB layout compatibility.

Obsolete Status Consideration:

SLPX331M200A3P3 carries Obsolete product status. While electrically equivalent, this part should be avoided for new designs or long-term production requirements due to limited future availability and potential supply discontinuation.

Frequently Asked Questions (FAQ)

Q: Can LLS2D331MELZ be used as a direct replacement for LLS2D331MELY?

A: Yes. Both parts share identical electrical specifications: 330 µF capacitance, 200 V voltage rating, ±20% tolerance, 3000 hours lifetime at 85°C, and identical lead spacing (10.00 mm). Physical dimensions differ slightly (diameter 22.00 mm vs. 20.00 mm; height 25.00 mm vs. 30.00 mm). Verify PCB layout accommodates the larger diameter before substitution.

Q: Is LLS2E331MELY compatible with circuits designed for LLS2D331MELY?

A: LLS2E331MELY is compatible in applications where the circuit voltage does not exceed 200 V. The higher 250 V rating provides additional safety margin. However, physical dimensions differ (height 35.00 mm vs. 30.00 mm). PCB layout verification is required to confirm clearance for the taller package.

Q: What is the difference between Nichicon and CDE equivalents?

A: Both manufacturers produce 330 µF, 200 V snap-in capacitors meeting identical electrical specifications. Nichicon parts (LLS2D331MELZ, LLS2E331MELY) and CDE parts (SLPX331M200A1P3, SLPX331M200A3P3) are functionally interchangeable. Selection may be based on inventory availability, supply chain preference, or cost considerations.

Q: Why is SLPX331M200A3P3 marked as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production. While existing inventory may be available, this part should not be selected for new designs or applications requiring long-term component availability. Use Active-status alternatives (LLS2D331MELZ or SLPX331M200A1P3) for new projects.

Q: Are there physical dimension constraints when substituting these parts?

A: Yes. While all parts maintain 10.00 mm lead spacing and snap-in package type, diameter and height vary: LLS2D331MELY and LLS2E331MELY have 20.00 mm diameter; LLS2D331MELZ and SLPX series have 22.00 mm diameter. Heights range from 25.00 mm to 35.00 mm. PCB layout must accommodate the specific physical dimensions of the selected substitute.

Q: Do ripple current ratings affect substitution decisions?

A: Ripple current ratings vary between parts (1.51 A to 1.68 A @ 120 Hz). Selection should verify that the chosen substitute meets or exceeds the ripple current requirements of the application circuit. Higher ripple current capability provides additional design margin.
