Substitute Part Grouping Explanation

Substitution for the 35MS533MEFC8X5 is determined by the following critical parameters: capacitance value (33 µF), tolerance (±20%), voltage rating (35 V or higher), lead spacing (2.50mm), case diameter (8.00mm), and through-hole radial mounting configuration. All substitute parts maintain identical capacitance, tolerance, and physical footprint dimensions. Voltage rating may be equal or higher; higher voltage ratings provide additional design margin. Lifetime at temperature and ripple current specifications may vary between manufacturers while maintaining functional equivalence for general-purpose applications.

The substitute parts are grouped into two categories:

Direct Equivalents maintain the 35 V voltage rating and 1000-hour lifetime specification.

Upgraded Alternatives feature higher voltage ratings (50 V) or extended lifetime (2000 Hrs @ 85°C), providing enhanced performance margins while maintaining full mechanical and electrical compatibility.

Engineering Selection Recommendations

ECE-A1VKS330 (Panasonic KS Series) provides direct electrical and mechanical equivalence to the obsolete Rubycon part. This active-status component maintains identical voltage rating, lifetime specification, and physical dimensions. Selection is appropriate for direct replacement in existing designs without modification.

ECE-A1HKA330 (Panasonic KA Series) offers upgraded voltage rating (50 V) while maintaining identical capacitance and tolerance. The increased voltage margin provides enhanced reliability in applications subject to voltage transients or design margin requirements. Height increases to 0.276" (7.00mm); verify PCB clearance before substitution.

EEA-GA1H330 (Panasonic GA-A Series) provides the highest performance specification with 50 V voltage rating and extended operating temperature range (-55°C ~ 105°C). Lifetime rating extends to 1000 hours at 105°C, supporting high-temperature applications. Height increases to 0.276" (7.00mm); verify PCB clearance before substitution.

UMR1V330MDD (Nichicon UMR Series) maintains 35 V voltage rating with doubled lifetime specification (2000 Hrs @ 85°C), providing extended service life in standard operating conditions. Height remains at 0.236" (6.00mm), matching the original part profile. Selection is appropriate for applications requiring enhanced reliability without voltage upgrade.

All substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can ECE-A1VKS330 be used as a direct replacement for 35MS533MEFC8X5?

A: Yes. ECE-A1VKS330 maintains identical electrical specifications (33 µF, ±20%, 35 V, 1000 Hrs @ 85°C) and physical dimensions (8.00mm diameter, 2.50mm lead spacing, 6.00mm height). No circuit modifications are required.

Q: What is the difference between the direct equivalent and upgraded alternatives?

A: ECE-A1VKS330 and UMR1V330MDD match the original 35 V rating. ECE-A1HKA330 and EEA-GA1H330 provide 50 V rating for increased voltage margin. EEA-GA1H330 additionally extends the operating temperature range to -55°C ~ 105°C and lifetime to 1000 Hrs @ 105°C.
