UPW2E100MPD Equivalent & Substitute Parts

Part Overview

The UPW2E100MPD is a 10 µF, 250 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is rated for 5000 hours at 105°C and is classified as obsolete. Due to its obsolete status, equivalent and substitute parts from active product lines or with extended operational lifetimes are necessary for new designs and ongoing production support.

Engineering Selection Recommendations

For Active Product Lines:

UCS2E100MPD (Nichicon) is the manufacturer-recommended substitute. It maintains identical electrical specifications while offering extended operational lifetime of 8000 hours at 105°C compared to the original 5000 hours. This part is in active production status and ROHS3 compliant.

250LLE10MEFC10X12.5 (Rubycon) and EKXF251ELL100MJC5S (Chemi-Con) both provide the longest operational lifetime at 15000 hours at 105°C. Both are active products and ROHS3 compliant. These options are suitable for applications requiring extended service life.

For Space-Constrained Applications:

UVY2E100MPD, EKXF251ELL100MJC5S, and MAL214231093E3 offer reduced physical height while maintaining all electrical parameters. Height ranges from 0.531" to 0.551" compared to the original 0.787".

For Voltage Margin Applications:

UPW2F100MPD provides a higher voltage rating of 315 V while maintaining the same 10 µF capacitance and 5000-hour lifetime. This option is suitable when additional voltage headroom is required, though it is classified as obsolete.

Parts to Avoid for New Designs:

UPS2E100MPD and UVY2E100MPD are marked "Not For New Designs" or "Obsolete." MAL214231093E3 and MAL214251093E3 offer only 2500-hour lifetime at 105°C, which is lower than the original specification.

Frequently Asked Questions (FAQ)

Q: Can UCS2E100MPD directly replace UPW2E100MPD?

A: Yes. UCS2E100MPD is the manufacturer-recommended substitute with identical capacitance (10 µF), voltage rating (250 V), tolerance (±20%), lead spacing (5.00 mm), case diameter (10.00 mm), and operating temperature range (-40°C to 105°C). The primary difference is extended lifetime (8000 hours vs. 5000 hours at 105°C) and slightly increased height (21.50 mm vs. 20.00 mm). Verify PCB layout clearance before substitution.

Q: What is the difference between the Nichicon and Chemi-Con alternatives?

A: Both UCS2E100MPD (Nichicon) and EKXF251ELL100MJC5S (Chemi-Con) meet all electrical and mechanical parameters. EKXF251ELL100MJC5S offers extended 15000-hour lifetime and reduced height (14.00 mm vs. 21.50 mm). Selection depends on available PCB space and required operational lifetime.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant, matching the original UPW2E100MPD compliance status.

Q: Can I use a 315 V rated capacitor (UPW2F100MPD) in place of the 250 V original?

A: Yes, from an electrical standpoint. Higher voltage ratings provide additional safety margin. However, UPW2F100MPD is classified as obsolete. For new designs, use active alternatives such as UCS2E100MPD or EKXF251ELL100MJC5S.

Q: What is the impact of different ripple current ratings?

A: Ripple current capacity varies among substitutes. UCS2E100MPD and EKXG251ELL100MJ20S support higher ripple currents (350 mA @ 100 kHz) compared to the original UPW2E100MPD (140.8 mA @ 10 kHz). Higher ripple current capacity indicates better performance in high-frequency switching applications. Verify application requirements before selection.

Q: Why do some parts have different physical heights?

A: Physical height variation reflects different internal construction and thermal management designs across manufacturers and product series. All listed parts maintain the same 10.00 mm case diameter and 5.00 mm lead spacing for PCB compatibility. Verify available vertical clearance on the PCB before substitution.

Q: Which substitute offers the longest operational life?

A: 250LLE10MEFC10X12.5 (Rubycon) and EKXF251ELL100MJC5S (Chemi-Con) both provide 15000-hour lifetime at 105°C, compared to 5000 hours for the original UPW2E100MPD.
