Critical Parameters (Must Match):

Capacitance: 2200 µF
Voltage Rating: 35 V minimum
Tolerance: ±20%
Polarization: Polar
Package Type: Radial, Can - Snap-In
Lead Spacing: 0.394" (10.00 mm)
Case Diameter: 0.866" (22.00 mm)
Height (Seated Max): 1.063" (27.00 mm)
Mounting Type: Through Hole
Operating Temperature Range: -40°C ~ 105°C

Allowable Variations:

ESR: Lower values are acceptable (improved performance)
Lifetime @ 105°C: Equal or greater values are acceptable
Ripple Current: Equal or greater values are acceptable
Voltage Rating: Higher ratings are acceptable (backward compatible)

Substitute parts are categorized as follows:

Direct Equivalents (35 V Rating): Parts with identical voltage rating, capacitance, and physical dimensions. These provide direct replacement capability.

Parametric Equivalents (35 V Rating): Parts meeting all critical parameters with improved electrical characteristics (lower ESR, extended lifetime).

Upgrade Substitutes (50 V Rating): Parts with elevated voltage rating (50 V vs. 35 V) while maintaining identical capacitance and physical form factor. These provide enhanced voltage margin and are mechanically and electrically compatible.

Engineering Selection Recommendations

Direct Equivalent Selection (35 V Rating):

B41505A7228M000 and B41505A7228M007 from EPCOS - TDK Electronics are direct equivalents with identical electrical and mechanical specifications. Both parts are active products with ROHS3 compliance. These parts feature improved ESR performance (85 mOhm vs. 196 mOhm) and extended lifetime (5000 hours vs. 3000 hours), providing superior reliability margins. Selection between these two variants depends on packaging requirements (both available in bulk).

381LX222M035H012 from Cornell Dubilier Electronics is a parametric equivalent meeting all critical specifications with ESR and lifetime characteristics matching the original part. This part is active and ROHS3 compliant, suitable for direct substitution where ESR performance is not a limiting factor.

Upgrade Substitute Selection (50 V Rating):

381LX222M050H012 from Cornell Dubilier Electronics and LGY1H222MELZ25 from Nichicon provide elevated voltage rating (50 V) while maintaining identical capacitance and physical form factor. Both parts are active products with ROHS3 compliance. The 50 V rating provides additional voltage margin for applications where circuit conditions may exceed the original 35 V specification. LGY1H222MELZ25 offers extended lifetime (5000 hours vs. 3000 hours), providing enhanced reliability for demanding applications.

All substitute parts maintain identical lead spacing (10.00 mm), case diameter (22.00 mm), and height (27.00 mm), ensuring direct mechanical compatibility with the original ECO-S1VA222BA footprint.

Frequently Asked Questions (FAQ)

Q: Can I use a 50 V rated capacitor in place of the 35 V ECO-S1VA222BA?

A: Yes. The 50 V upgrade substitutes (381LX222M050H012 and LGY1H222MELZ25) are mechanically and electrically compatible. Higher voltage ratings provide additional safety margin and are backward compatible with 35 V circuit designs. No circuit modifications are required.

Q: What is the difference between B41505A7228M000 and B41505A7228M007?

A: Both parts are electrically identical with 2200 µF capacitance, 35 V rating, 85 mOhm ESR, and 5000-hour lifetime. The primary difference is packaging designation. Both are suitable for direct substitution of the ECO-S1VA222BA.

Q: Why does 381LX222M035H012 have higher ESR (200 mOhm) than B41505A7228M000 (85 mOhm)?

A: ESR varies by manufacturer design and construction. Both values meet the allowable parameter range for substitution. The 381LX222M035H012 remains a valid parametric equivalent. Applications sensitive to ESR performance should prioritize the EPCOS B41505 series for lower impedance characteristics.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts are ROHS3 compliant, meeting current environmental and regulatory requirements. The original ECO-S1VA222BA compliance status is not specified in available documentation.

Q: Can I mix different substitute parts in the same circuit board?

A: Yes. All substitute parts meet identical critical parameters (capacitance, voltage, tolerance, physical dimensions, and operating temperature range) and are mechanically and electrically interchangeable. Mixed sourcing is acceptable from a functional standpoint.

Q: What is the inventory status of these substitute parts?

A: B41505A7228M000 (1546 pcs), B41505A7228M007 (1126 pcs), 381LX222M035H012 (835 pcs), 381LX222M050H012 (7885 pcs), and LGY1H222MELZ25 (1022 pcs) are all available as new original stock.
