Tolerance: ±20%
Package Type: Radial, Can - Snap-In
Lead Spacing: 0.394" (10.00 mm)
Mounting Type: Through Hole

Engineering Selection Recommendations

Direct Equivalents (Recommended Primary Choices):

The 200USG820MEFC25X30 and 200USG820MEFCSN25X30 from Rubycon are direct electrical equivalents with identical capacitance, voltage, and tolerance specifications. Both are ROHS3 compliant and active products with substantial inventory availability. The primary consideration is reduced height (1.260" vs. 1.772"), which may require mechanical clearance verification in existing designs.

The 827LBB200M2CF from Cornell Dubilier / Illinois Capacitor provides direct electrical equivalence with comparable ESR (202.18 mOhm) and is ROHS3 compliant. Height is 1.654", offering a middle ground between the original and Rubycon options.

The LLS2D821MELA from Nichicon matches all critical electrical parameters and is ROHS3 compliant with active product status. Height is 1.378", requiring clearance assessment.

The SLPX821M200C7P3 from Cornell Dubilier Electronics (CDE) provides direct equivalence with 3000-hour lifetime rating and ROHS3 compliance. Height is 1.575".

Upgraded Options (Enhanced Performance):

The LGU2D821MELA from Nichicon offers extended operating temperature range (-40°C to 105°C) and 3000-hour lifetime at 105°C, providing thermal margin beyond the original specification. Electrical parameters remain equivalent at 200 V, 820 µF, ±20%.

The LLS2E821MELA from Nichicon provides voltage upgrade to 250 V while maintaining 820 µF capacitance and 3000-hour lifetime. This option is suitable for applications requiring additional voltage margin.

Alternative Options (Reduced Lifetime):

The LPX821M200C4P3 from CDE provides electrical equivalence but with reduced lifetime rating (1000 hours at 85°C vs. 3000 hours). Selection requires confirmation that reduced lifetime is acceptable for the application.

The 380LQ821M200H042 and 380LQ821M200K012 from CDE both provide 2000-hour lifetime ratings, intermediate between the LPX and full 3000-hour options. Dimensional variations require mechanical clearance verification.

Compliance Status:

All active substitute parts listed are ROHS3 compliant. The original ECO-S2DP821CA is REACH Affected; all active substitutes are REACH Unaffected, providing regulatory advantage for new designs.

Frequently Asked Questions (FAQ)

Q: Can I use a 250 V rated capacitor in place of the 200 V original?

A: Yes. The LLS2E821MELA (250 V, 820 µF) is electrically compatible and provides voltage margin. Higher voltage ratings do not degrade performance in 200 V applications.

Q: What is the impact of different physical heights on substitution?

A: Physical height variation is acceptable if mechanical clearance exists in the PCB layout and enclosure. The original is 1.772" (45.00 mm). Shorter alternatives (Rubycon at 1.260", Nichicon LLS2D at 1.378") require verification that no mechanical interference occurs. Taller alternatives are not available.

Q: Does ESR variation affect circuit performance?

A: ESR differences within the range provided (202–243 mOhm) are minor and typically do not affect general-purpose applications. The original ESR is 222 mOhm. Substitutes with similar or lower ESR values are functionally equivalent.

Q: Why is the LPX821M200C4P3 listed if it has only 1000-hour lifetime?

A: This part provides electrical equivalence but with reduced lifetime. It is suitable only for applications where 1000-hour operation at 85°C meets design requirements. For designs requiring 3000-hour lifetime, direct equivalents or upgraded options are recommended.

Q: Are all substitutes through-hole, snap-in packages?

A: Yes. All listed substitutes maintain the radial, can-style snap-in package with 0.394" (10.00 mm) lead spacing and through-hole mounting, ensuring mechanical and electrical compatibility with the original footprint.

Q: What is the difference between the two Rubycon parts (200USG820MEFC25X30 and 200USG820MEFCSN25X30)?

A: Both are electrically identical 820 µF, 200 V capacitors with 3000-hour lifetime. The primary difference is inventory availability (273,982 pcs vs. 4,843 pcs). Selection depends on supply chain requirements.

Q: Can I use LGU2D821MELA for applications operating above 85°C?

A: Yes. The LGU2D821MELA is rated for 3000 hours at 105°C and supports operating temperatures from -40°C to 105°C, providing thermal headroom for applications with elevated ambient or component temperatures.
