Engineering Selection Recommendations

Both substitute parts maintain full mechanical and electrical compatibility with the UCS2V100MPD based on identical physical dimensions, lead spacing, and mounting configuration.

UCS2G100MPD provides a direct upgrade path within the Nichicon UCS series, offering increased voltage rating (400 V versus 350 V) while maintaining identical capacitance, tolerance, and lifetime specifications. This part is suitable for applications requiring higher voltage margin without performance trade-offs.

EKXF451ELL100MJ20S, manufactured by Chemi-Con, offers the highest voltage rating (450 V) and extended operational lifetime (20000 Hrs @ 105°C versus 8000 Hrs @ 105°C). This part is suitable for applications requiring enhanced reliability and extended service life. Note that ripple current ratings are lower than the main part and UCS2G100MPD.

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

Frequently Asked Questions (FAQ)

Q: Can UCS2G100MPD be used as a direct replacement for UCS2V100MPD?

A: Yes. UCS2G100MPD is mechanically and electrically compatible. It shares identical capacitance (10 µF), tolerance (±20%), physical dimensions, lead spacing, and mounting type. The higher voltage rating (400 V) provides additional safety margin in the circuit.

Q: What is the primary difference between UCS2G100MPD and EKXF451ELL100MJ20S?

A: Both parts are mechanically compatible with UCS2V100MPD. UCS2G100MPD maintains the same 8000 Hrs @ 105°C lifetime as the original part. EKXF451ELL100MJ20S extends lifetime to 20000 Hrs @ 105°C and increases voltage rating to 450 V, but has lower ripple current specifications (92 mA @ 120 Hz and 230 mA @ 100 kHz versus 175 mA and 350 mA respectively).

Q: Are there any physical dimension differences between these parts?

A: No. All three parts share identical physical dimensions (0.394" diameter, 0.846" maximum seated height), lead spacing (0.197" / 5.00mm), and radial can package configuration. They are mechanically interchangeable on PCBs designed for the UCS2V100MPD.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. UCS2G100MPD and EKXF451ELL100MJ20S are both ROHS3 compliant and REACH unaffected, matching the compliance profile of UCS2V100MPD.

Q: Which substitute part should be selected for high-reliability applications?

A: Selection depends on circuit voltage requirements and expected operational lifetime. For applications operating below 400 V with standard lifetime requirements, UCS2G100MPD is appropriate. For applications requiring extended service life or operating at higher voltages, EKXF451ELL100MJ20S is suitable, provided ripple current specifications meet circuit requirements.
