Equivalent & Substitute Parts for ECO-S2WP820CA

Part Overview

The ECO-S2WP820CA is an 82 µF, 450 V aluminum electrolytic capacitor manufactured by Panasonic Electronic Components in the TS-UP series. This radial, can-style snap-in capacitor is rated for 3000 hours at 85°C with an ESR of 2.022 Ohm @ 120Hz and is designed for general purpose applications. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing system support and new designs requiring this capacitance and voltage rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECO-S2WP820CA is determined by the following mandatory parameters:

• Capacitance: 82 µF (exact match required)
• Voltage - Rated: 450 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Package / Case: Radial, Can - Snap-In (exact match required)
• Lead Spacing: 0.394" (10.00mm) (exact match required)
• Mounting Type: Through Hole (exact match required)

All substitute parts listed meet these core electrical and mechanical parameters. Variations in ESR, lifetime ratings, operating temperature range, and physical dimensions (diameter and height) are permitted within the constraints of the snap-in package form factor and through-hole mounting compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Preferred): The 380LX820M450J012 (Cornell Dubilier Electronics) is the primary direct substitute. It maintains identical electrical specifications (82 µF, 450 V, ±20% tolerance, 3000 Hrs @ 85°C) and is currently in active production status with ROHS3 compliance. The height difference of 1.063" versus 0.984" requires verification of available mounting clearance in the target application.

Upgraded Alternative: The LGU2W820MELA (Nichicon) offers enhanced thermal performance with a 3000-hour lifetime rating at 105°C versus 85°C, supporting extended operating temperature range (-25°C ~ 105°C). This part is ROHS3 compliant and maintains identical physical dimensions to the original part. Selection of this upgrade is appropriate for applications requiring improved thermal margin or higher ambient temperature operation.

Secondary Alternatives: The 380LX820M450H022 (Cornell Dubilier Electronics) and ESMQ451VSN820MP25S (Chemi-Con) meet all core substitution parameters but present dimensional variations. The 380LX820M450H022 has reduced diameter (0.866" versus 0.984") with increased height (1.260"), while the ESMQ451VSN820MP25S has similar diameter reduction with standard height (0.984"). Both require physical layout verification.

The LPX820M450C1P3 (Cornell Dubilier Electronics) is suitable only for applications where reduced lifetime (1000 Hrs @ 85°C) is acceptable, as it does not meet the 3000-hour specification of the original part.

All substitute parts maintain REACH compliance status and EAR99 export classification consistent with the original ECO-S2WP820CA.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with different physical dimensions? A: Physical dimensions must be verified against available mounting space in your application. While all listed substitutes maintain the 0.394" (10.00mm) lead spacing and snap-in package form factor required for through-hole mounting, variations in diameter and height may affect board layout. Confirm clearance before implementation.

Q: What is the significance of ESR differences between parts? A: ESR (Equivalent Series Resistance) affects ripple current handling and heat dissipation. The original ECO-S2WP820CA specifies 2.022 Ohm @ 120Hz. Substitute parts with similar ESR values (380LX820M450H022 at 2 Ohm, LPX820M450C1P3 at 2.426 Ohm) provide comparable performance. Parts with unspecified ESR require application-specific ripple current analysis.

Q: Why do some substitutes have different lifetime ratings? A: Lifetime ratings (measured in hours at specified temperature) reflect capacitor design and construction. The original part specifies 3000 Hrs @ 85°C. The LGU2W820MELA maintains this rating at the higher temperature of 105°C, indicating superior thermal stability. The ESMQ451VSN820MP25S specifies 2000 Hrs @ 85°C, which is lower and may not be suitable for applications requiring the full 3000-hour specification.

Q: Are all substitute parts RoHS compliant? A: Yes. All listed substitute parts carry either ROHS3 Compliant or RoHS Compliant status. The original ECO-S2WP820CA does not specify RoHS status. All parts maintain EAR99 export classification and identical HTSUS code (8532.22.0040).

Q: What is the difference between "Direct," "Upgrade," and "Similar" substitutes? A: Direct substitutes (380LX820M450J012) match all electrical specifications and lifetime ratings. Upgrade substitutes (LGU2W820MELA) offer enhanced performance characteristics such as higher temperature rating while maintaining core specifications. Similar substitutes meet core electrical parameters but may have variations in lifetime, ESR, or physical dimensions requiring application-specific evaluation.

Q: Can I interchange these parts without circuit redesign? A: All listed parts maintain the same capacitance (82 µF), voltage rating (450 V), tolerance (±20%), and mounting type (through-hole, snap-in). Interchange is mechanically and electrically feasible provided physical dimensions are verified for available mounting space and ripple current requirements are confirmed against ESR specifications.
