ECO-S2AA222CA Equivalent & Substitute Parts

Part Overview

The ECO-S2AA222CA is a 2200 µF, 100 V aluminum electrolytic capacitor in radial, can snap-in package manufactured by Panasonic Electronic Components. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations. The part operates across a temperature range of -40°C to 105°C with a rated lifetime of 3000 hours at 105°C and an ESR of 90 mOhm at 120 Hz. Substitute parts must maintain electrical compatibility while meeting current availability and compliance requirements.

Substitute Part Grouping Explanation

Substitution of the ECO-S2AA222CA is determined by the following criteria:

Primary Compatibility Parameters:

Capacitance: 2200 µF (exact match required)
Voltage Rating: 100 V minimum (equal or higher acceptable)
Tolerance: ±20% (standard for aluminum electrolytic capacitors)
Package: Radial, Can - Snap-In (mechanical and electrical interface requirement)
Lead Spacing: 0.394" (10.00 mm) (PCB footprint compatibility)
Mounting: Through Hole (assembly process compatibility)
Polarization: Polar (electrical polarity requirement)

Secondary Considerations:

Operating temperature range: -40°C to 105°C (functional envelope)
ESR and ripple current ratings: Performance characteristics that may vary within acceptable limits
Lifetime at temperature: Service life expectancy

Substitute parts are grouped into two categories:

Direct Upgrade (100 V rated): Parts with identical voltage rating and enhanced specifications (longer lifetime, improved compliance status, active product status).

Functional Equivalent (Lower Voltage Rating): Parts rated at 63 V or 80 V. These are suitable only in applications where the actual operating voltage does not exceed the substitute part's rating. These parts are not interchangeable in all circuit configurations.

Engineering Selection Recommendations

Direct Substitutes (100 V Rated - Preferred):

LGY2A222MELA50 (Nichicon) is the primary recommended substitute. It maintains 100 V voltage rating, identical capacitance and tolerance, matching lead spacing and package type. The part is active with ROHS3 compliance and offers extended lifetime of 5000 hours at 105°C compared to the original 3000 hours.

MAL215839222E3 (Vishay Beyschlag/Draloric/BC Components) is an alternative direct substitute with 100 V rating, 5000-hour lifetime, and ROHS3 compliance. Physical dimensions differ (1.181" diameter × 1.457" height versus 0.984" × 2.047"), requiring PCB layout verification for space constraints.

SLP222M100C4P3, SLP222M100E5P3, and SLP222M100H3P3 (Cornell Dubilier Electronics) are functionally equivalent at 100 V with 3000-hour lifetime and ROHS3 compliance. These parts have varying physical dimensions; verify PCB footprint compatibility before selection.

B41252A9228M000 (EPCOS - TDK Electronics) maintains 100 V rating and ROHS3 compliance but offers reduced lifetime of 2000 hours at 105°C. Select only if space constraints or other design factors necessitate this part.

LP222M100H7P3 (Cornell Dubilier Electronics) is rated 100 V with ROHS3 compliance but has the shortest lifetime at 1000 hours at 105°C. Use only in applications with limited operational duration or non-critical lifetime requirements.

Functional Equivalents (Lower Voltage Rating - Conditional Use):

63VXG2200MEFCSN25X30 (Rubycon) and 80MXG2200MEFCSN25X30 (Rubycon) are suitable only in circuits where the actual operating voltage does not exceed 63 V and 80 V respectively. These parts are not interchangeable with the 100 V rated ECO-S2AA222CA in all applications. Verify circuit operating voltage before selection. The 63 V non-compliant variant (63VXG2200MEFC25X30) should be avoided in new designs requiring RoHS compliance.

Frequently Asked Questions (FAQ)

Q: Can I use a 63 V or 80 V rated capacitor in place of the 100 V ECO-S2AA222CA?

A: Only if the actual circuit operating voltage does not exceed the substitute part's voltage rating. Capacitors rated below the circuit voltage will experience reduced lifetime and increased failure risk. Verify the maximum voltage stress in your application before substitution.

Q: What is the significance of ESR (Equivalent Series Resistance) in selecting a substitute?

A: ESR affects ripple current handling and heat generation. The ECO-S2AA222CA has 90 mOhm ESR at 120 Hz. Substitute parts with higher ESR values (113–141 mOhm) will generate more heat under ripple current stress. Select based on your circuit's ripple current requirements and thermal environment.

Q: Does physical size matter when substituting capacitors?

A: Yes. While all listed parts share the same 0.394" (10.00 mm) lead spacing, physical dimensions vary significantly. Verify that the substitute part's diameter and height fit within your PCB layout and enclosure constraints before selection.

Q: Why is LGY2A222MELA50 recommended as the primary substitute?

A: LGY2A222MELA50 matches the original part's voltage rating (100 V), capacitance (2200 µF), tolerance (±20%), and lead spacing (10.00 mm). It is active with ROHS3 compliance and offers superior lifetime (5000 hours versus 3000 hours at 105°C), making it the most direct functional replacement.

Q: Are all substitute parts RoHS compliant?

A: Most listed substitutes are ROHS3 compliant. The original ECO-S2AA222CA is marked as REACH Affected. The 63VXG2200MEFC25X30 variant is RoHS non-compliant; use only if compliance is not required. Verify compliance requirements for your application before final selection.

Q: What is the difference between "Active" and "Obsolete" product status?

A: Active parts are currently manufactured and available from distributors. Obsolete parts are no longer produced. The ECO-S2AA222CA is obsolete, necessitating substitution with active alternatives to ensure long-term supply chain continuity.

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

A: All listed substitutes are electrically compatible at the same voltage rating and capacitance. However, mixing parts with different ESR values or lifetimes may result in uneven current distribution and varying thermal performance. Use identical part numbers across the same circuit for consistency.
