LGU2D221MELY Equivalent & Substitute Parts

Part Overview

The LGU2D221MELY is a 220 µF, 200 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 industrial temperature ranges. The component is rated for 3000 hours at 105°C and operates reliably between -40°C and 105°C. As an active product with ROHS3 compliance, the LGU2D221MELY remains in production. Identifying equivalent substitute parts is essential for supply chain continuity, design flexibility, and procurement optimization when the primary part becomes unavailable or when alternative sourcing improves cost efficiency.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LGU2D221MELY is determined by strict equivalence across the following critical parameters:

• Electrical Specifications: Capacitance value (220 µF), voltage rating (200 V), and tolerance (±20%) must match exactly
• Thermal Performance: Lifetime rating of 3000 hours at 105°C and operating temperature range of -40°C to 105°C must be maintained
• Mechanical Compatibility: Package type (Radial, Can - Snap-In), lead spacing (10.00 mm), and through-hole mounting must be identical to ensure PCB compatibility
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status must be preserved

The substitute part 381LX221M200H012 (Cornell Dubilier Electronics) meets all these criteria and qualifies as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The 381LX221M200H012 (Cornell Dubilier Electronics) is electrically and functionally equivalent to the LGU2D221MELY. Both components are active products with identical electrical specifications, thermal ratings, and regulatory compliance status (ROHS3 and REACH unaffected).

Physical dimensions show minor variance: the CDE substitute has a slightly larger diameter (22.00 mm vs. 20.00 mm) and greater seated height (27.00 mm vs. 25.00 mm). These dimensional differences must be evaluated against specific PCB layout constraints and available mounting space in the target application. Lead spacing remains identical at 10.00 mm, ensuring compatibility with standard through-hole footprints.

Both parts maintain equivalent ripple current performance across the specified frequency ranges, supporting identical power delivery and thermal management characteristics in circuit operation.

Frequently Asked Questions (FAQ)

Q: Can the 381LX221M200H012 be used as a direct replacement for the LGU2D221MELY?

A: Yes, the 381LX221M200H012 is electrically and functionally equivalent. Both components share identical capacitance (220 µF), voltage rating (200 V), tolerance (±20%), thermal lifetime (3000 Hrs @ 105°C), operating temperature range (-40°C ~ 105°C), and lead spacing (10.00 mm). Physical dimensions differ slightly; verify available PCB mounting space before substitution.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution requires exact matching of capacitance value, voltage rating, tolerance, thermal lifetime, operating temperature range, polarization, package type (Radial, Can - Snap-In), lead spacing, and mounting type (Through Hole). Regulatory compliance (ROHS3, REACH status) must also be preserved.

Q: Are there dimensional concerns when substituting the 381LX221M200H012?

A: The substitute part has a larger diameter (22.00 mm vs. 20.00 mm) and greater seated height (27.00 mm vs. 25.00 mm). Confirm that PCB layout and enclosure clearances accommodate these dimensions before implementation.

Q: Do both parts have the same ripple current ratings?

A: Both parts deliver 1 A ripple current at 120 Hz. High-frequency ripple current is 1.5 A @ 50 kHz for the LGU2D221MELY and 1.4 A @ 20 kHz for the 381LX221M200H012. These values are comparable and support equivalent circuit performance.

Q: What is the regulatory compliance status of both parts?

A: Both the LGU2D221MELY and 381LX221M200H012 are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations.
