ECO-S2DA221AA Equivalent & Substitute Parts

Part Overview

The ECO-S2DA221AA is a 220 µF, 200 V aluminum electrolytic capacitor manufactured by Panasonic Electronic Components in the TS-HA series. This radial, can-style snap-in capacitor is designed for general-purpose applications requiring through-hole mounting. The part is currently obsolete, making equivalent substitutes necessary for ongoing system support and new designs requiring compatible specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ECO-S2DA221AA is determined by strict equivalence across the following critical parameters:

• Capacitance value: 220 µF
• Voltage rating: 200 V
• Tolerance: ±20%
• Package type: Radial, Can - Snap-In
• Mounting configuration: Through Hole
• Lead spacing: 0.394" (10.00mm)
• Physical diameter: 0.787" (20.00mm)
• Operating temperature range: -40°C ~ 105°C
• Lifetime specification: 3000 Hrs @ 105°C

The LGU2D221MELY from Nichicon meets all these core electrical and mechanical requirements, establishing it as a direct functional equivalent despite differences in physical height and ESR specifications.

Parameter Comparison

Engineering Selection Recommendations

The LGU2D221MELY is the qualified substitute for the ECO-S2DA221AA based on the following factors:

Electrical Equivalence: Both capacitors share identical capacitance (220 µF), voltage rating (200 V), tolerance (±20%), and thermal lifetime specification (3000 Hrs @ 105°C). Operating temperature ranges are identical.

Mechanical Compatibility: Lead spacing (10.00mm), can diameter (20.00mm), and snap-in package configuration are identical, ensuring direct PCB footprint compatibility without layout modifications.

Product Availability: The LGU2D221MELY is currently in active production status with 1167 pieces in stock, whereas the ECO-S2DA221AA is obsolete. This makes the Nichicon part the practical choice for new procurement and system support.

Compliance Status: The LGU2D221MELY is ROHS3 compliant and REACH unaffected, providing regulatory advantages over the non-compliant ECO-S2DA221AA.

Physical Differences: The LGU2D221MELY has a reduced seated height of 0.984" (25.00mm) compared to 1.260" (32.00mm) for the original part. This dimensional reduction may provide space benefits in compact designs and does not compromise electrical performance.

Frequently Asked Questions (FAQ)

Q: Can the LGU2D221MELY be used as a direct replacement for the ECO-S2DA221AA?

A: Yes. Both capacitors meet identical electrical specifications (220 µF, 200 V, ±20%, 3000 Hrs @ 105°C) and share the same mechanical footprint (10.00mm lead spacing, 20.00mm diameter, snap-in package). The reduced height of the Nichicon part (25.00mm vs. 32.00mm) is a dimensional improvement that does not affect circuit performance.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by matching capacitance value, voltage rating, tolerance, polarization, package type, lead spacing, physical diameter, operating temperature range, and thermal lifetime specification. All these parameters are identical between the two parts.

Q: Does the height difference between the two capacitors affect PCB compatibility?

A: No. The LGU2D221MELY's reduced height (25.00mm) is shorter than the original ECO-S2DA221AA (32.00mm), which provides additional clearance in the vertical direction. This does not create compatibility issues and may benefit space-constrained designs.

Q: Are there compliance or regulatory differences between these parts?

A: Yes. The LGU2D221MELY is ROHS3 compliant and REACH unaffected, while the ECO-S2DA221AA is RoHS non-compliant. For applications requiring regulatory compliance, the Nichicon part is the appropriate choice.

Q: What is the ripple current rating difference?

A: The ECO-S2DA221AA specifies 1.4 A @ 100 kHz, while the LGU2D221MELY specifies 1.5 A @ 50 kHz. Both parts support the 1 A @ 120 Hz low-frequency ripple current requirement, which is the standard operating condition for general-purpose applications.
