Substitute Part Grouping Explanation

Substitution for the ECO-S2DB471BA is determined by strict adherence to the following electrical and mechanical parameters:

Core Substitution Criteria:

Capacitance: 470 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)
Lead Spacing: 0.394" (10.00 mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Operating Temperature Range: -40°C to 105°C (exact match required)
Polarization: Polar (exact match required)

Secondary Considerations:

Lifetime at 105°C: Minimum 2000 hours
ESR and ripple current specifications: May vary within acceptable operational limits
Physical dimensions (diameter and height): Variations permitted within mechanical envelope constraints
Product status: Active status preferred for long-term availability

Parts meeting all core criteria are classified as direct substitutes. Parts meeting core criteria with minor dimensional variations are classified as similar substitutes.

Engineering Selection Recommendations

Direct Substitutes (Preferred):

The following parts meet all core electrical and mechanical parameters and are recommended as primary substitutes:

200MXG470MEFCSN20X35 (Rubycon MXG series): Active product status with 3000-hour lifetime rating. Dimensional variation in diameter (20.00 mm vs. 22.00 mm) and height (37.00 mm vs. 35.00 mm) is acceptable for most through-hole applications with standard PCB spacing.
381LQ471M200H022 (Cornell Dubilier Electronics 381LQ series): Active product status. Lifetime rating of 2000 hours meets minimum substitution threshold. Identical diameter (22.00 mm) with reduced height (32.00 mm) provides improved mechanical fit in space-constrained designs.
B43508A2477M000 (EPCOS - TDK Electronics B43508 series): Active product status with 3000-hour lifetime rating and RoHS3 compliance. Identical diameter (22.00 mm) with increased height (37.00 mm) accommodates standard through-hole mounting.
LGN2D471MELZ30 (Nichicon LGN series): Active product status with 3000-hour lifetime rating. Identical diameter and reduced height (32.00 mm) suitable for compact PCB layouts.
LGW2D471MELZ30 (Nichicon LGW series): Active product status with 3000-hour lifetime rating and highest ripple current capability (2.17 A @ 120 Hz, 3.255 A @ 50 kHz). Compact height (30.00 mm) for space-constrained applications.

Similar Substitutes (Conditional):

The following parts meet all core electrical parameters with dimensional variations that may require mechanical evaluation:

381LR471M200H032 (Cornell Dubilier Electronics 381LR series): Active product status with 3000-hour lifetime rating. Identical diameter (22.00 mm) with increased height (37.00 mm).
381LR471M200J022 (Cornell Dubilier Electronics 381LR series): Active product status with 3000-hour lifetime rating. Increased diameter (25.00 mm) and reduced height (32.00 mm) requires PCB layout verification.
381LX471M200J022 (Cornell Dubilier Electronics 381LX series): Active product status with 3000-hour lifetime rating. Increased diameter (25.00 mm) and reduced height (32.00 mm) requires PCB layout verification.
381LX471M200K012 (Cornell Dubilier Electronics 381LX series): Active product status with 3000-hour lifetime rating. Increased diameter (30.00 mm) and reduced height (27.00 mm) requires mechanical clearance validation.

Limited Substitutes (Not Recommended):

LP471M200E1P3 (Cornell Dubilier Electronics LP series): Active product status but lifetime rating of 1000 hours at 105°C is significantly reduced compared to the original 3000-hour specification. Increased diameter (30.00 mm) and reduced height (25.00 mm) also require mechanical evaluation. Use only when lifetime requirements are relaxed.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with different physical dimensions?

A: Physical dimensions (diameter and height) may vary within the constraints of your PCB layout and mechanical enclosure. All listed substitutes maintain the same lead spacing (10.00 mm) and through-hole mounting type. Verify that the substitute part fits within your available vertical and horizontal space before implementation. Compact variants (reduced height) are generally preferred for space-constrained designs.

Q: What is the significance of the lifetime rating difference between parts?

A: Lifetime rating indicates the expected operational duration at maximum rated temperature (105°C) before capacitance degradation exceeds specified tolerances. The original ECO-S2DB471BA specifies 3000 hours at 105°C. Most direct substitutes maintain this rating. The 381LQ471M200H022 offers 2000 hours, which is acceptable for applications with less stringent reliability requirements. The LP471M200E1P3 offers only 1000 hours and should be used only when system design permits reduced lifetime expectations.

Q: Are all substitute parts RoHS compliant?

A: RoHS3 compliance is confirmed for all active substitute parts listed. The original ECO-S2DB471BA is obsolete and predates current RoHS requirements. All recommended substitutes meet current environmental and regulatory standards.

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

A: Direct substitutes meet all core electrical and mechanical parameters with minimal dimensional variation. Similar substitutes meet all electrical parameters but have dimensional variations (diameter or height) that may require PCB layout or mechanical clearance verification before implementation.

Q: Can I interchange parts with different ESR values?

A: ESR (Equivalent Series Resistance) affects ripple current handling and thermal performance. The original part specifies 423 mOhm @ 120 Hz. Substitutes with lower ESR values (such as B43508A2477M000 at 250 mOhm @ 100 Hz) provide improved performance. Substitutes with higher ESR values may be acceptable if ripple current requirements are not exceeded. Verify ripple current specifications for your specific application.

Q: Which substitute offers the best performance for high-ripple-current applications?

A: The LGW2D471MELZ30 (Nichicon LGW series) provides the highest ripple current capability at 2.17 A @ 120 Hz and 3.255 A @ 50 kHz, making it suitable for demanding power supply and filtering applications. The 200MXG470MEFCSN20X35 (Rubycon MXG series) also offers strong ripple current performance at 1.76 A @ 120 Hz and 2.64 A @ 10 kHz.

Q: Is the snap-in mounting type critical for substitution?

A: Yes. All listed substitutes maintain the radial, can-style snap-in package type and through-hole mounting configuration. This ensures mechanical compatibility with existing PCB designs and component holders. Do not substitute with different package types (such as surface-mount or axial configurations) without complete design revision.
