Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following core parameters:

Capacitance: 2200 µF (exact match required)
Voltage Rating: 200 V (exact match required)
Tolerance: ±20% (exact match required)
Package Type: Radial, Can - Snap-In (exact match required)
Mounting Type: Through Hole (exact match required)
Lead Spacing: 0.394" (10.00mm) (exact match required)
Diameter: 1.378" (35.00mm) (exact match required)
Operating Temperature Range: -40°C to 105°C (exact match required)
Lifetime @ 105°C: 3000 Hours (exact match required)

Substitute parts are classified into two categories:

Direct Equivalents: Parts meeting all core parameters with identical or superior electrical performance characteristics.

Similar Equivalents: Parts meeting all core parameters but with variations in secondary characteristics such as ESR, ripple current ratings, or lifetime specifications that differ from the original part.

Engineering Selection Recommendations

All listed substitute parts are active products with RoHS3 compliance or equivalent regulatory status, ensuring long-term availability and environmental compliance. Selection should prioritize parts with matching height specifications to minimize PCB layout modifications.

Preferred Direct Equivalents:

381LX222M200A052 (Cornell Dubilier Electronics) and LGU2D222MELC (Nichicon) are direct parametric equivalents with 3000-hour lifetime ratings matching the original specification. Both are ROHS3 compliant and widely available.

B43508A2228M000 (EPCOS - TDK Electronics) offers superior ESR performance at 55mOhm and a compact height of 1.850", providing improved electrical characteristics within the same footprint class.

Alternative Selections:

LGW2D222MELC45 (Nichicon) provides the most compact height at 1.772" with enhanced ripple current capability, suitable for space-constrained applications.

381LR222M200A052 (Cornell Dubilier Electronics) delivers improved ESR at 66mOhm with 3000-hour lifetime, offering a balance between performance and availability.

Not Recommended for Direct Substitution:

381LQ222M200A452 and 381LQ222M200K052 feature reduced lifetime ratings of 2000 hours at 105°C, below the original 3000-hour specification. 381LQ222M200K052 also has a non-standard diameter of 1.181" (30mm), requiring PCB layout verification.

383LX222M200A052 is a 4-lead variant with different mechanical configuration, requiring board-level design changes.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a different height?

A: Height variations exist among the listed equivalents. Verify PCB clearance and mechanical constraints before selection. Parts with reduced height (1.772" to 1.850") offer space savings; parts with increased height (2.047") require clearance verification above the component.

Q: What is the significance of ESR differences between parts?

A: ESR (Equivalent Series Resistance) affects ripple current handling and thermal performance. Lower ESR values indicate superior high-frequency performance. The original part specifies 105mOhm @ 120Hz; substitutes range from 55mOhm to 96mOhm. Lower ESR values provide improved performance margins.

Q: Why do some parts have 2000-hour lifetime ratings instead of 3000 hours?

A: Lifetime ratings reflect capacitor design and construction. The original ECO-S2DB222EA specifies 3000 hours at 105°C. Parts with 2000-hour ratings have reduced thermal endurance and should only be selected if application duty cycles do not require the full 3000-hour specification.

Q: Are all substitute parts RoHS compliant?

A: All listed active substitutes are ROHS3 compliant or REACH unaffected, meeting current environmental regulations. The original obsolete part carries REACH Affected status.

Q: What is the difference between direct and similar equivalents?

A: Direct equivalents match all core electrical and mechanical parameters. Similar equivalents meet core parameters but may have variations in secondary characteristics such as ESR, ripple current, or lifetime. Both categories are electrically compatible within the specified parameter ranges.

Q: Can I substitute the 4-lead variant (383LX222M200A052)?

A: The 383LX222M200A052 is a 4-lead snap-in variant, differing from the standard 2-lead configuration. Substitution requires verification of PCB pad layout and mechanical mounting compatibility.
