LLS2C271MELY Equivalent & Substitute Parts

Part Overview

The LLS2C271MELY is a 270 µF, 160 V aluminum electrolytic capacitor in radial, can snap-in package manufactured by Nichicon. This component is designed for general-purpose applications requiring stable capacitance and reliable performance across industrial temperature ranges. The part is currently active in production with full RoHS3 compliance. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity when the primary part becomes unavailable or when design requirements permit alternative specifications within the same electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitution of the LLS2C271MELY is determined by strict equivalence in the following critical parameters:

• Capacitance value: 270 µF (exact match required)
• Rated voltage: 160 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Package type: Radial, Can - Snap-In (exact match required)
• Lead spacing: 0.394" (10.00 mm) (exact match required)
• Physical dimensions: 0.787" Dia × 0.984" Height (exact match required)
• Mounting type: Through Hole (exact match required)

The LGU2C271MELY qualifies as a direct substitute based on identical electrical ratings, mechanical dimensions, and package specifications. Variations in operating temperature range and ripple current ratings do not preclude substitution when the application environment and ripple current demands fall within the substitute part's specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the LLS2C271MELY and LGU2C271MELY are active production parts with full ROHS3 compliance and REACH unaffected status. Selection between these parts depends on application-specific requirements:

The LLS2C271MELY operates across -40°C to 85°C with rated lifetime of 3000 hours at 85°C and supports higher ripple current specifications (1.28 A @ 120 Hz, 1.92 A @ 50 kHz).

The LGU2C271MELY operates across -40°C to 105°C with rated lifetime of 3000 hours at 105°C and supports lower ripple current specifications (1.1 A @ 120 Hz, 1.65 A @ 50 kHz).

Selection should be based on the application's operating temperature environment and ripple current demands. Both parts meet identical mechanical and electrical core specifications for 270 µF, 160 V, ±20% tolerance aluminum electrolytic capacitors in snap-in radial can packages.

Frequently Asked Questions (FAQ)

Q: Can LGU2C271MELY replace LLS2C271MELY in all applications?

A: Substitution is valid when the application environment operates within -40°C to 105°C and ripple current demands do not exceed 1.1 A @ 120 Hz or 1.65 A @ 50 kHz. If the application requires higher ripple current handling or operates exclusively below 85°C, the LLS2C271MELY is the appropriate choice.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts share identical lead spacing (0.394" / 10.00 mm), diameter (0.787" / 20.00 mm), and maximum seated height (0.984" / 25.00 mm). PCB layout and mechanical mounting are fully compatible.

Q: What is the significance of the different operating temperature ranges?

A: The LGU2C271MELY supports extended operation to 105°C, while the LLS2C271MELY is rated to 85°C. This difference reflects the thermal design of each series. Applications in high-temperature environments should verify that the selected part's temperature rating matches or exceeds the maximum ambient temperature plus any self-heating from ripple current.

Q: Do these parts require different handling or storage procedures?

A: Both parts are aluminum electrolytic capacitors with identical moisture sensitivity classification (Not Applicable) and packaging specifications. Standard handling and storage procedures for Nichicon aluminum electrolytic capacitors apply to both.

Q: Are there inventory or lead time considerations for substitution?

A: Inventory levels may differ between series. Verify current stock availability with your supplier before finalizing part selection for time-sensitive applications.
