UPS2E100MPD Equivalent & Substitute Parts

Part Overview

The UPS2E100MPD is a 10 µF, 250 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as obsolete, with 2153 units currently in stock. The part operates across a temperature range of -40°C to 105°C with a rated lifetime of 2000 hours at 105°C, suitable for general-purpose applications requiring polar capacitive storage.

Due to its obsolete status, equivalent and substitute parts are necessary for ongoing design support, production continuity, and long-term component availability. Substitutes are selected based on matching or exceeding electrical performance within the same mechanical envelope and mounting configuration.

Engineering Selection Recommendations

Direct Equivalents (Nichicon UCS Series - Recommended Primary Choice)

UCS2E100MPD is the manufacturer-recommended direct equivalent. This active-status part maintains identical electrical specifications (10 µF, 250 V, ±20%) while providing extended lifetime (8000 hours at 105°C versus 2000 hours) and improved ripple current handling (350 mA at 100 kHz versus 140.8 mA). The UCS series is ROHS3 compliant and actively manufactured, ensuring long-term availability. Height difference of 0.020" (0.50 mm) remains within typical PCB layout tolerances.

Higher Voltage Alternatives (Nichicon UCS Series)

UCS2V100MPD (350 V) and UCS2G100MPD (400 V) provide voltage margin above the 250 V requirement while maintaining identical capacitance, tolerance, and mechanical footprint. These parts are suitable for applications requiring overvoltage protection or operating in elevated voltage environments. Both are active-status, ROHS3 compliant, and offer 8000-hour lifetime at 105°C.

Extended Temperature Operation (Nichicon UBT Series)

UBT2E100MPD8 is specified for automotive applications with extended temperature rating (-40°C to 125°C) and 2000-hour lifetime at 125°C. This part matches the original height (0.866") and is active-status, ROHS3 compliant. Selection is appropriate for high-temperature environments or automotive-grade reliability requirements.

Alternative Manufacturers (Rubycon and Chemi-Con)

Rubycon 250LLE10MEFC10X12.5 and Chemi-Con EKXF251ELL100MJC5S both provide 15000-hour lifetime at 105°C with ROHS3 compliance and active product status. These parts feature reduced height (0.571" and 0.551" respectively), enabling space-constrained designs. Rubycon 250PX10MEFC10X12.5 offers 2000-hour lifetime matching the original specification with active status and compact form factor.

Legacy Parts (Not Recommended for New Designs)

Nichicon UVY2E100MPD and UVZ2E100MPD are classified as "Not For New Designs" and should be avoided in new product development. These parts are retained for existing design support and repair applications only.

Frequently Asked Questions (FAQ)

Q: Can UCS2E100MPD directly replace UPS2E100MPD without PCB modification?

A: Yes. Both parts share identical lead spacing (0.197" / 5.00 mm), case diameter (0.394" / 10.00 mm), and electrical specifications (10 µF, 250 V, ±20%). The height difference of 0.020" (0.50 mm) is within standard PCB clearance tolerances and does not require layout changes.

Q: What is the advantage of selecting UCS2E100MPD over UPW2E100MPD?

A: UCS2E100MPD offers active product status with 8000-hour lifetime at 105°C, compared to UPW2E100MPD's obsolete status and 5000-hour lifetime. UCS2E100MPD also provides superior ripple current handling (350 mA at 100 kHz versus 140.8 mA), enabling better performance in high-frequency switching applications.

Q: Are higher voltage ratings (UCS2V100MPD, UCS2G100MPD) backward compatible?

A: Yes. Higher voltage ratings are electrically compatible with 250 V circuits. These parts provide overvoltage margin and are suitable for applications with voltage transients or design margin requirements. No circuit modification is necessary.

Q: What is the difference between Nichicon and alternative manufacturer parts?

A: All listed substitutes meet identical electrical specifications (10 µF, 250 V, ±20%) and mechanical requirements (radial, can, through-hole, 5.00 mm lead spacing). Differences exist in lifetime ratings, ripple current capacity, and form factor. Rubycon and Chemi-Con alternatives offer extended lifetime (15000 hours) and compact heights, suitable for space-constrained or high-reliability applications.

Q: Can compact-height alternatives (Rubycon LLE, Chemi-Con KXF) be used in existing designs?

A: Compact alternatives are electrically compatible but require PCB layout verification. Rubycon 250LLE10MEFC10X12.5 and Chemi-Con EKXF251ELL100MJC5S feature heights of 0.571" and 0.551" respectively, compared to the original 0.866". Verify clearance above the capacitor before substitution.

Q: Why is UBT2E100MPD8 recommended for automotive applications?

A: UBT2E100MPD8 is specified for automotive-grade reliability with extended temperature rating (-40°C to 125°C) and 2000-hour lifetime at 125°C. This part meets automotive environmental and thermal stress requirements while maintaining identical electrical and mechanical specifications to the original UPS2E100MPD.

Q: Should legacy parts (UVY2E100MPD, UVZ2E100MPD) be used in new designs?

A: No. Both parts are classified as "Not For New Designs" and should be reserved for existing product support and repair applications only. Active-status alternatives (UCS series, Rubycon, Chemi-Con) are recommended for all new development.
