Engineering Selection Recommendations

For Direct Replacement (Identical Footprint and Performance): SLP822M025A5P3 (Cornell Dubilier Electronics) is the primary direct substitute. It maintains identical lead spacing (10.00 mm), capacitance (8200 µF), voltage rating (25 V), and lifetime specification (3000 Hrs @ 105°C). The part is ROHS3 compliant and REACH unaffected, providing regulatory advantage over the obsolete ECO-S1EA822BA. ESR is slightly elevated at 73 mOhm versus 61 mOhm, which remains acceptable for general-purpose applications.

For Enhanced Reliability: LGY1E822MELZ35 (Nichicon) offers an upgrade path with extended lifetime (5000 Hrs @ 105°C). This part maintains identical electrical specifications and footprint dimensions (0.866" Dia, 37.00 mm height), making it a direct mechanical replacement. ROHS3 compliance and REACH unaffected status provide regulatory alignment.

For Space-Constrained Applications: SLP822M025E1P3 (Cornell Dubilier Electronics) provides a compact alternative with reduced height (0.984" / 25.00 mm) while maintaining all critical electrical parameters. This option is suitable for designs where vertical clearance is limited.

For Dimensional Flexibility: 381LX822M025J022 and 381LX822M025K012 (Cornell Dubilier Electronics) accommodate larger diameter requirements (0.984" and 1.181" respectively) while preserving electrical specifications. These options are applicable when PCB layout permits increased footprint dimensions.

Avoid for New Designs: B41252A5828M (EPCOS - TDK Electronics) has a reduced lifetime specification (2000 Hrs @ 105°C), making it unsuitable for applications requiring the standard 3000-hour rating.

All substitute parts maintain the required 25 V voltage rating, 8200 µF capacitance, ±20% tolerance, and through-hole snap-in mounting configuration.

Frequently Asked Questions (FAQ)

Q: Can SLP822M025A5P3 be used as a direct replacement for ECO-S1EA822BA? A: Yes. SLP822M025A5P3 matches all critical parameters: 8200 µF capacitance, 25 V rating, ±20% tolerance, 10.00 mm lead spacing, 0.866" diameter, and 3000-hour lifetime at 105°C. The slightly higher ESR (73 mOhm vs. 61 mOhm) is within acceptable limits for general-purpose applications.

Q: What is the advantage of LGY1E822MELZ35 over the direct substitute? A: LGY1E822MELZ35 provides extended lifetime (5000 Hrs @ 105°C vs. 3000 Hrs), offering improved reliability for long-term operation. It maintains identical footprint and electrical specifications, making it a direct mechanical and electrical upgrade.

Q: Are there space-saving alternatives? A: Yes. SLP822M025E1P3 reduces height to 0.984" (25.00 mm) from the standard 1.457" (37.00 mm), while maintaining all electrical specifications. This option is suitable for applications with vertical space constraints.

Q: Do all substitute parts meet RoHS and REACH compliance? A: All listed substitute parts are ROHS3 compliant and REACH unaffected, providing regulatory advantage over the obsolete ECO-S1EA822BA, which is REACH affected.

Q: Why is B41252A5828M not recommended? A: B41252A5828M has a reduced lifetime specification of 2000 Hrs @ 105°C, below the standard 3000-hour rating of the original part. It is suitable only for applications with lower reliability requirements.

Q: Can parts with different physical dimensions be used interchangeably? A: Physical dimensions must be verified against PCB layout constraints. While 381LX822M025J022 and 381LX822M025K012 maintain electrical compatibility, their larger diameters (0.984" and 1.181" respectively) require confirmation of available board space before substitution.

Q: What is the significance of lead spacing in substitution? A: All substitute parts maintain the 0.394" (10.00 mm) lead spacing, ensuring compatibility with existing PCB through-hole patterns. This parameter is critical for mechanical fit and must not vary.
