LGU2F271MELB Equivalent & Substitute Parts

Part Overview

The LGU2F271MELB is a 270 µF, 315 V aluminum electrolytic capacitor manufactured by Nichicon in the LGU series. This radial, can-style snap-in capacitor is rated for 3000 hours at 105°C and is designed for general-purpose applications requiring through-hole mounting. The part is currently active in production with ROHS3 compliance and REACH unaffected status. Substitute parts are identified when equivalent capacitance and tolerance values are maintained while voltage ratings or series designations differ, enabling component flexibility in circuit design and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LGU2F271MELB is determined by strict adherence to the following electrical and mechanical parameters:

Critical Parameters for Substitution:

• Capacitance: 270 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Package / Case: Radial, Can - Snap-In (exact match required)
• Mounting Type: Through Hole (exact match required)
• Lead Spacing: 0.394" (10.00 mm) (exact match required)
• Physical Dimensions: 1.181" Dia (30.00 mm), Height 1.063" (27.00 mm) (exact match required)
• Operating Temperature Range: -25°C ~ 105°C (exact match required)

Parameters Allowed to Vary:

• Voltage - Rated: May be equal to or higher than 315 V
• Series Designation: May differ (LGU, LGN, or equivalent series)
• Manufacturer: Nichicon or equivalent qualified manufacturer
• Ripple Current Values: May vary within acceptable operating parameters

The LGN2V271MELB25 qualifies as a substitute because it maintains all critical parameters while providing a higher voltage rating (350 V) and belongs to an equivalent Nichicon series.

Parameter Comparison

Engineering Selection Recommendations

Both the LGU2F271MELB and LGN2V271MELB25 are active production parts with ROHS3 compliance and REACH unaffected status, making them suitable for applications requiring regulatory compliance. The LGN2V271MELB25 provides a higher voltage rating (350 V versus 315 V) while maintaining identical capacitance, tolerance, physical dimensions, and thermal characteristics. Selection between these parts depends on circuit voltage requirements and design margins. Both parts are manufactured by Nichicon and carry equivalent reliability ratings of 3000 hours at 105°C.

Frequently Asked Questions (FAQ)

Q: Can the LGN2V271MELB25 be used in place of the LGU2F271MELB?

A: Yes. The LGN2V271MELB25 maintains identical capacitance (270 µF), tolerance (±20%), physical dimensions, lead spacing, and thermal ratings. The higher voltage rating (350 V) is compatible with circuits designed for 315 V operation.

Q: What are the physical compatibility requirements for substitution?

A: Substitute parts must have identical lead spacing (0.394" / 10.00 mm), case diameter (1.181" / 30.00 mm), and seated height (1.063" / 27.00 mm). Both the main part and substitute meet these requirements for direct through-hole mounting.

Q: Are there differences in ripple current handling between these parts?

A: Ripple current values differ slightly between the parts. The LGU2F271MELB is rated at 1.16 A @ 120 Hz and 1.6588 A @ 50 kHz. The LGN2V271MELB25 is rated at 1.1 A @ 120 Hz and 1.573 A @ 50 kHz. Circuit design must account for these specifications.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the LGU2F271MELB and LGN2V271MELB25 are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements for industrial and commercial applications.

Q: What is the operating temperature range for both parts?

A: Both parts operate across the identical temperature range of -25°C to 105°C with a rated lifetime of 3000 hours at 105°C.
