Substitute parts for the ECO-S2AA272DA are classified based on electrical and mechanical compatibility within the following criteria:

Core Substitution Parameters:

Capacitance: 2700 µF (exact match required)
Voltage Rating: 100 V (exact match required)
Tolerance: ±20% (exact match required)
Package: Radial, Can - Snap-In (exact match required)
Lead Spacing: 0.394" (10.00 mm) (exact match required)
Physical Dimensions: 1.181" Dia × 1.850" Height (exact match required)
Mounting: Through Hole (exact match required)
Operating Temperature: -40°C to 105°C (exact match required)

Upgrade Substitutes offer improved lifetime ratings (5000 hours at 105°C vs. 3000 hours) while maintaining all core electrical and mechanical parameters. These parts are from active product lines and provide enhanced reliability.

Similar Substitutes maintain all core parameters but with different lifetime ratings (2000 hours at 105°C) and are suitable where the original specification allows for reduced operational life.

Parametric Equivalents match all core parameters and lifetime specifications (3000 hours at 105°C), providing direct functional equivalence from alternative manufacturers.

Engineering Selection Recommendations

For Direct Replacement with Enhanced Reliability: Select 100VXG2700MEFCSN30X45 (Rubycon VXG series) or LGY2A272MELB45 (Nichicon LGY series). Both parts are active products with 5000-hour lifetime ratings at 105°C, providing improved operational life over the obsolete ECO-S2AA272DA. The Rubycon part offers ROHS3 compliance, while the Nichicon part maintains equivalent performance characteristics.

For Equivalent Functional Replacement: Select LGU2A272MELB (Nichicon LGU series) or 381LX272M100K452 (Cornell Dubilier 381LX series). Both maintain the 3000-hour lifetime specification matching the original part and are active products with ROHS3 compliance.

For Cost-Optimized Replacement: Select B41252A9278M (EPCOS B41252 series). This part is active and ROHS3 compliant but operates at a reduced 2000-hour lifetime at 105°C. Use this option only where application requirements permit reduced operational life.

All substitute parts maintain identical electrical specifications (2700 µF, 100 V, ±20% tolerance), physical dimensions, and through-hole mounting compatibility with the original ECO-S2AA272DA.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts as a direct drop-in replacement for the ECO-S2AA272DA?

A: Yes. All listed substitute parts share identical capacitance (2700 µF), voltage rating (100 V), tolerance (±20%), package type (radial snap-in), lead spacing (10 mm), physical dimensions (30 mm diameter × 47 mm height), and through-hole mounting configuration. They are mechanically and electrically interchangeable.

Q: What is the difference between "Upgrade," "Similar," and "Parametric Equivalent" classifications?

A: Upgrade substitutes (Rubycon VXG, Nichicon LGY series) provide extended 5000-hour lifetime at 105°C versus the original 3000 hours. Similar substitutes (EPCOS B41252) operate at reduced 2000-hour lifetime. Parametric equivalents (Nichicon LGU, CDE 381LX) match the original 3000-hour specification exactly.

Q: Does RoHS compliance matter for my application?

A: RoHS compliance is determined by regulatory requirements for your end product and market. The ECO-S2AA272DA is RoHS non-compliant. Most substitute parts (100VXG2700MEFCSN30X45, LGY2A272MELB45, B41252A9278M, 381LX272M100K452, LGU2A272MELB) are ROHS3 compliant. The Rubycon 100VXG2700MEFC30X45 is RoHS non-compliant.

Q: How do ripple current ratings affect my selection?

A: Ripple current capacity is provided for reference. All substitute parts maintain ripple current performance within acceptable ranges for general-purpose applications. The original ECO-S2AA272DA specifies 2.9 A at 120 Hz; substitute parts range from 2.4 A to 3.27 A at 120 Hz, all suitable for equivalent circuit operation.

Q: What is the advantage of selecting a higher lifetime-rated part?

A: Extended lifetime ratings (5000 hours vs. 3000 hours at 105°C) indicate longer operational durability under thermal stress. Upgrade substitutes provide improved reliability margin for applications requiring extended service life or operating in elevated-temperature environments.

Q: Are there any mechanical considerations when substituting these parts?

A: No. All substitute parts maintain identical lead spacing (10 mm), can diameter (30 mm), and height (47 mm). PCB footprints and mounting hardware remain unchanged. Snap-in mounting compatibility is preserved across all alternatives.
