LGU2F221MELY Equivalent & Substitute Parts

Part Overview

The LGU2F221MELY is a 220 µF, 315 V aluminum electrolytic capacitor manufactured by Nichicon in the LGU series. This radial, can-style snap-in capacitor is designed for general-purpose applications requiring stable performance across extended temperature ranges. The part is currently active in production with 830 units in stock. 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 configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LGU2F221MELY is determined by the following critical parameters:

• Capacitance value: 220 µF (exact match required)
• Voltage rating: 315 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Mounting type: Through Hole (exact match required)
• Package style: Radial, Can - Snap-In (exact match required)
• Lead spacing: 0.394" (10.00 mm) (exact match required)
• Operating temperature range: -25°C ~ 105°C (exact match required)
• Lifetime rating: 3000 Hrs @ 105°C (exact match required)
• Compliance: ROHS3 Compliant, REACH Unaffected (exact match required)

The LGU2F221MELB qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. Physical dimensions (can diameter and height) may vary within the snap-in package specification without affecting functional compatibility in the circuit.

Parameter Comparison

Engineering Selection Recommendations

Both the LGU2F221MELY and LGU2F221MELB are active production parts from Nichicon with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on:

• Inventory availability: LGU2F221MELY has 830 units in stock; LGU2F221MELB has 920 units in stock
• Ripple current performance: LGU2F221MELB provides marginally higher ripple current ratings at both 120 Hz and 50 kHz
• Physical form factor: LGU2F221MELB features a larger diameter (1.181" vs. 0.787") and reduced height (1.063" vs. 2.047"), which may impact PCB layout considerations

Both parts meet identical electrical specifications and regulatory requirements. Physical dimension differences do not affect electrical performance in applications where the snap-in package footprint is accommodated.

Frequently Asked Questions (FAQ)

Q: Can LGU2F221MELB be used as a direct replacement for LGU2F221MELY?

A: Yes. Both parts share identical capacitance (220 µF), voltage rating (315 V), tolerance (±20%), operating temperature range (-25°C ~ 105°C), lifetime rating (3000 Hrs @ 105°C), and compliance certifications. The parts are electrically and functionally equivalent.

Q: What are the physical differences between these parts?

A: The LGU2F221MELY has a can diameter of 0.787" (20.00 mm) and height of 2.047" (52.00 mm). The LGU2F221MELB has a can diameter of 1.181" (30.00 mm) and height of 1.063" (27.00 mm). Both maintain the same 0.394" (10.00 mm) lead spacing and snap-in mounting interface.

Q: Are there ripple current differences?

A: Minor differences exist. At 120 Hz, LGU2F221MELB provides 1.04 A versus 1 A for LGU2F221MELY. At 50 kHz, LGU2F221MELB provides 1.4872 A versus 1.43 A for LGU2F221MELY. These differences are negligible for general-purpose applications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, with identical regulatory status.

Q: Which part should be selected for new designs?

A: Selection should be based on PCB layout constraints and current inventory. Both parts are active production items with equivalent performance characteristics. Verify physical dimensions against available board space before final selection.
