Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LLS2D271MELZ is determined by strict adherence to the following electrical and mechanical parameters:

Critical Parameters (Must Match):

• Capacitance: 270 µF
• Voltage Rating: 200 V
• Tolerance: ±20%
• Polarization: Polar
• Package Type: Radial, Can - Snap-In
• Mounting Type: Through Hole
• Lead Spacing: 0.394" (10.00 mm)
• Case Diameter: 0.866" (22.00 mm)

Allowable Variations:

• Operating Temperature Range: May extend beyond -40°C ~ 85°C
• Lifetime Rating: May differ at rated temperature
• Height (Seated Max): Tolerance of ±0.079" (±2.00 mm) acceptable
• Ripple Current: May vary within application limits
• ESR: May vary based on series design

Three substitute parts meet these criteria and are classified as follows:

Direct Manufacturer Equivalent: LGU2D271MELZ (Nichicon) — Same manufacturer, identical electrical specifications, extended temperature rating to 105°C.

Similar Manufacturer Parts: 380LX271M200H012 (Cornell Dubilier Electronics) and SLPX271M200A1P3 (Cornell Dubilier Electronics) — Alternative manufacturers with matching core parameters and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All four parts—LLS2D271MELZ, LGU2D271MELZ, 380LX271M200H012, and SLPX271M200A1P3—are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for industrial and commercial applications.

LGU2D271MELZ is the preferred direct equivalent when the primary part is unavailable. It maintains identical electrical specifications and mechanical compatibility while offering an extended operating temperature range to 105°C, providing enhanced thermal margin for demanding environments.

380LX271M200H012 and SLPX271M200A1P3 are viable alternatives from Cornell Dubilier Electronics. Both maintain core electrical parameters and mechanical fit. The 380LX271M200H012 exhibits a maximum seated height of 1.063" (27.00 mm), which is 0.079" (2.00 mm) taller than the primary part; verify clearance in confined PCB layouts before selection. The SLPX271M200A1P3 maintains the original height specification of 0.984" (25.00 mm) and matches ripple current performance at the primary frequency.

Selection among substitute parts should be based on inventory availability, lead time, and specific application thermal and ripple current requirements.

Frequently Asked Questions (FAQ)

Q: Can LGU2D271MELZ be used as a direct replacement for LLS2D271MELZ?

A: Yes. LGU2D271MELZ is a direct manufacturer equivalent from Nichicon with identical capacitance, voltage rating, tolerance, package type, and mechanical dimensions. The extended operating temperature range to 105°C provides additional thermal capability without compromising compatibility.

Q: What is the key difference between the Nichicon and Cornell Dubilier substitute parts?

A: All parts share identical electrical specifications (270 µF, 200 V, ±20% tolerance) and mechanical compatibility (radial snap-in package, 10.00 mm lead spacing, 22.00 mm diameter). The primary differences are manufacturer, series designation, and minor variations in ripple current and ESR characteristics. The 380LX271M200H012 has a slightly increased seated height of 1.063" (27.00 mm) compared to 0.984" (25.00 mm) for the other parts.

Q: Are there any height restrictions when using 380LX271M200H012?

A: The 380LX271M200H012 has a maximum seated height of 1.063" (27.00 mm), which is 0.079" (2.00 mm) taller than the LLS2D271MELZ. Verify available vertical clearance on the PCB and within the enclosure before selection to ensure mechanical fit.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All four parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for industrial and commercial electronics applications.

Q: Which substitute part should I select for high-ripple-current applications?

A: The LLS2D271MELZ and SLPX271M200A1P3 both support 1.37 A ripple current at 120 Hz. The LGU2D271MELZ supports 1.1 A at 120 Hz, and the 380LX271M200H012 supports 1.4 A at 120 Hz. Select based on your specific ripple current requirements at the operating frequency.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided that the mechanical height constraint is verified. All parts maintain the same lead spacing (10.00 mm), case diameter (22.00 mm), and snap-in mounting interface. The 380LX271M200H012 requires height clearance verification due to its increased seated height.
