Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, ensuring continued availability and regulatory conformance.

UCS2V100MPD (350 V Rating): This Nichicon part provides a 100 V voltage margin above the original specification while maintaining identical mechanical dimensions and 8000-hour lifetime rating. Selection is appropriate when higher voltage headroom is required within the same thermal performance envelope.

UCS2G100MPD (400 V Rating): This Nichicon part provides a 150 V voltage margin above the original specification while maintaining identical mechanical dimensions and 8000-hour lifetime rating. Selection is appropriate when maximum voltage margin is required within the same thermal performance envelope.

EKXF451ELL100MJ20S (450 V Rating): This Chemi-Con part provides a 200 V voltage margin above the original specification and extends the lifetime rating to 20000 hours at 105°C. The ripple current specifications are lower than the original part. Selection is appropriate when extended operational lifetime and maximum voltage margin are required, provided that the lower ripple current rating is compatible with the application.

Frequently Asked Questions (FAQ)

Q: Can UCS2V100MPD, UCS2G100MPD, or EKXF451ELL100MJ20S be used as direct replacements for UCS2E100MPD?

A: Yes. All substitute parts share identical capacitance (10 µF), tolerance (±20%), mechanical dimensions, lead spacing, and mounting type. The substitute parts feature equal or higher voltage ratings and equal or extended lifetime specifications, making them electrically and mechanically compatible for direct board-level substitution.

Q: What is the difference between the three substitute parts?

A: The primary differences are voltage rating and lifetime specification. UCS2V100MPD offers 350 V rating with 8000-hour lifetime. UCS2G100MPD offers 400 V rating with 8000-hour lifetime. EKXF451ELL100MJ20S offers 450 V rating with 20000-hour lifetime but features lower ripple current specifications (92 mA @ 120 Hz and 230 mA @ 100 kHz compared to 175 mA and 350 mA respectively).

Q: Does the higher voltage rating of substitute parts affect circuit performance?

A: No. A capacitor with a higher voltage rating than required will function identically in the circuit. The voltage rating indicates the maximum voltage the capacitor can safely withstand; operating at a lower voltage than the rating does not degrade performance.

Q: Are there any package or footprint differences between these parts?

A: No. All parts share identical lead spacing (0.197" / 5.00mm), case diameter (0.394" / 10.00mm), and maximum seated height (0.846" / 21.50mm). They are mechanically interchangeable on through-hole PCB layouts.

Q: Why does EKXF451ELL100MJ20S have lower ripple current ratings?

A: Ripple current specifications are determined by the internal construction and thermal design of the capacitor. The EKXF451ELL100MJ20S achieves its extended 20000-hour lifetime through different internal design parameters, which result in lower ripple current handling. Verify that the application's ripple current requirements do not exceed 92 mA @ 120 Hz or 230 mA @ 100 kHz before selecting this part.

Q: Are all substitute parts RoHS compliant?

A: Yes. All parts listed are ROHS3 compliant and maintain Active product status, ensuring regulatory compliance and continued manufacturing support.
