Equivalent & Substitute Parts for LLS2D271MELY

Part Overview

The LLS2D271MELY is a 270 µF, 200 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 performance across a wide operating temperature range of -40°C to 85°C, with a rated lifetime of 3000 hours at 85°C. The part is ROHS3 compliant and currently in active production status with 1127 units in stock.

Equivalent and substitute parts become necessary when the primary part number is unavailable, when inventory constraints require alternative sourcing, or when design flexibility permits selection from qualified alternatives that meet identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LLS2D271MELY is determined by strict equivalence across the following critical parameters:

• Electrical Equivalence: Capacitance value (270 µF), voltage rating (200 V), and tolerance (±20%) must be identical
• Thermal Performance: Lifetime rating of 3000 hours at 85°C and operating temperature range of -40°C to 85°C must be maintained
• Mechanical Compatibility: Lead spacing of 0.394" (10.00mm), radial snap-in package configuration, and through-hole mounting must be preserved
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status required

Three substitute parts meet these criteria: LLS2D271MELZ (Nichicon), 380LX271M200H012 (Cornell Dubilier Electronics), and SLPX271M200A1P3 (Cornell Dubilier Electronics). All three maintain identical electrical ratings, thermal specifications, lead spacing, and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

All four parts—LLS2D271MELY, LLS2D271MELZ, 380LX271M200H012, and SLPX271M200A1P3—are active production components with ROHS3 compliance and REACH unaffected status, qualifying them for equivalent use in general-purpose applications.

Nichicon LLS Series (LLS2D271MELY and LLS2D271MELZ): Both parts are from the same manufacturer and series, with identical electrical and thermal specifications. The LLS2D271MELZ features a slightly larger can diameter (22.00mm versus 20.00mm) but maintains the same height and lead spacing. Selection between these two Nichicon variants depends on available inventory and PCB layout constraints related to can diameter.

Cornell Dubilier Electronics 380LX Series (380LX271M200H012): This part maintains electrical and thermal equivalence with a can diameter of 22.00mm and maximum height of 1.063" (27.00mm), which is 0.079" taller than the primary part. This height difference requires verification against available PCB clearance in the target application.

Cornell Dubilier Electronics SLPX Series (SLPX271M200A1P3): This part provides electrical and thermal equivalence with a can diameter of 22.00mm and height matching the LLS2D271MELZ at 0.984" (25.00mm). The SLPX series offers the highest inventory availability at 4093 units.

Selection among these substitutes should prioritize PCB layout compatibility, particularly regarding can diameter and height clearance, while considering inventory availability and supply chain lead times.

Frequently Asked Questions (FAQ)

Q: Can LLS2D271MELZ be used as a direct replacement for LLS2D271MELY?

A: Yes. Both parts share identical capacitance (270 µF), voltage rating (200 V), tolerance (±20%), thermal lifetime (3000 Hrs @ 85°C), operating temperature range (-40°C ~ 85°C), lead spacing (10.00mm), and regulatory compliance (ROHS3, REACH unaffected). The primary difference is can diameter: LLS2D271MELZ measures 22.00mm versus 20.00mm for LLS2D271MELY. Verify PCB layout accommodates the larger diameter before substitution.

Q: Are Cornell Dubilier Electronics parts compatible with Nichicon parts in this specification?

A: Yes, within mechanical constraints. The 380LX271M200H012 and SLPX271M200A1P3 maintain identical electrical ratings, voltage, capacitance, tolerance, and thermal performance. Both feature 22.00mm can diameter and 10.00mm lead spacing. The 380LX271M200H012 has a maximum height of 1.063" (27.00mm), which exceeds other variants. The SLPX271M200A1P3 matches the height of LLS2D271MELZ at 0.984" (25.00mm). Verify PCB clearance before selection.

Q: What is the significance of can diameter differences among these parts?

A: Can diameter affects PCB layout and component density. The LLS2D271MELY has a 20.00mm diameter, while LLS2D271MELZ, 380LX271M200H012, and SLPX271M200A1P3 all measure 22.00mm. A 2.00mm increase in diameter may impact board routing, adjacent component placement, and thermal management. Confirm available space on the target PCB before substitution.

Q: Do all substitute parts meet the same regulatory requirements?

A: Yes. All four parts are ROHS3 compliant and REACH unaffected, meeting identical regulatory standards for use in regulated applications and markets.

Q: What inventory considerations apply to these substitutes?

A: Current stock levels vary: LLS2D271MELY (1127 units), LLS2D271MELZ (983 units), 380LX271M200H012 (2554 units), and SLPX271M200A1P3 (4093 units). Higher inventory availability may reduce lead times and support supply chain continuity for high-volume production requirements.
