ECO-S1EA822DA Equivalent & Substitute Parts

Part Overview

The ECO-S1EA822DA is an 8200 µF, 25 V aluminum electrolytic capacitor in radial, can snap-in package manufactured by Panasonic Electronic Components. This part operates across -40°C to 105°C with a rated lifetime of 3000 hours at 105°C and is classified as obsolete. Due to its obsolete status, equivalent and substitute parts from active manufacturers are necessary for ongoing production and maintenance applications requiring 8200 µF capacitance at 25 V or higher voltage ratings with compatible mechanical and electrical characteristics.

Substitute Part Grouping Explanation

Substitution for the ECO-S1EA822DA is determined by the following criteria:

Direct Equivalents maintain identical electrical specifications: 8200 µF capacitance, ±20% tolerance, 25 V rated voltage, through-hole radial snap-in package, 10.00 mm lead spacing, and 30.00 mm diameter. These parts are interchangeable without circuit modification.

Upgrade Substitutes increase the rated voltage from 25 V to 35 V or higher while maintaining 8200 µF capacitance, ±20% tolerance, and compatible mechanical dimensions. These provide enhanced voltage margin and are electrically backward-compatible in 25 V applications.

Similar Parts share the same capacitance and voltage rating but differ in physical dimensions (diameter or height) or electrical characteristics (ESR, ripple current). These require PCB layout verification before substitution.

Engineering Selection Recommendations

Direct Replacement (No Circuit Modification Required): 381LX822M025K012 from Cornell Dubilier Electronics is the primary direct equivalent, maintaining identical capacitance, voltage, tolerance, lifetime, and mechanical dimensions. This part is active and ROHS3 compliant.

Preferred Upgrade (Backward Compatible): 35MXG8200MEFCSN30X25 from Rubycon provides increased voltage rating (35 V vs. 25 V) while preserving all mechanical dimensions and capacitance specifications. This upgrade is suitable for applications requiring enhanced voltage margin and is ROHS3 compliant.

Extended Lifetime Alternative: LGY1E822MELB25 from Nichicon offers identical electrical and mechanical specifications to the original part but with extended lifetime (5000 hours vs. 3000 hours at 105°C). This part is ROHS3 compliant and suitable for applications requiring improved reliability.

Higher Voltage Alternatives: 50MXG8200MEFCSN30X35, 50VXG8200MEFCSN30X50, and 63MXG8200MEFCSN30X40 from Rubycon provide 50 V and 63 V ratings respectively. These parts require verification of available PCB space due to increased height. 50VXG8200MEFCSN30X50 offers extended 5000-hour lifetime.

Dimensional Variants: 381LX822M025J022, SLP822M025A5P3, and SLP822M025C3P3 maintain 25 V rating and 8200 µF capacitance but feature different diameter and height combinations. These require PCB layout confirmation before substitution.

All recommended active parts are ROHS3 compliant and REACH unaffected, suitable for current production environments.

Frequently Asked Questions (FAQ)

Q: Can I use a 35 V or 50 V rated capacitor in place of the 25 V ECO-S1EA822DA? A: Yes. Higher voltage-rated capacitors are electrically backward-compatible in 25 V applications. The circuit will operate safely with increased voltage margin. However, verify available PCB space, as higher voltage ratings typically result in increased physical height.

Q: What is the difference between direct equivalents and upgrade substitutes? A: Direct equivalents (such as 381LX822M025K012) maintain identical specifications including voltage rating, physical dimensions, and electrical characteristics. Upgrade substitutes (such as 35MXG8200MEFCSN30X25) increase the voltage rating while preserving mechanical compatibility, providing enhanced performance margin.

Q: Does ESR (Equivalent Series Resistance) affect substitution compatibility? A: ESR affects ripple current handling and thermal performance. The original part specifies 61 mOhm @ 120 Hz. Substitute parts with higher ESR (such as 73 mOhm in Cornell Dubilier SLP series) may generate additional heat under high ripple current conditions. Verify ripple current requirements in your application before substitution.

Q: Are all substitute parts RoHS compliant? A: All active substitute parts listed are ROHS3 compliant. The original ECO-S1EA822DA is obsolete and does not carry RoHS certification. Current production designs should specify active, RoHS3-compliant alternatives.

Q: What is the significance of lifetime rating (3000 Hrs vs. 5000 Hrs @ 105°C)? A: Lifetime rating indicates the expected operational duration at maximum rated temperature. Parts with 5000-hour ratings (such as LGY1E822MELB25 and 50VXG8200MEFCSN30X50) provide extended service life in high-temperature environments. Select based on application reliability requirements.

Q: Can I substitute a part with different physical dimensions? A: Physical dimensions must be verified against PCB layout constraints. Parts with identical diameter (30.00 mm) but different heights are generally preferred. Parts with different diameters (such as 22.00 mm or 25.00 mm variants) require PCB redesign confirmation.

Q: What packaging options are available? A: All substitute parts are supplied in bulk packaging and feature through-hole radial snap-in mounting. Lead spacing is standardized at 0.394" (10.00 mm) across all direct and upgrade equivalents, ensuring compatibility with existing PCB footprints.
