Engineering Selection Recommendations

Direct Replacement (Same Voltage, Active Status)

UVR2E100MPD1AA is the recommended direct replacement. It maintains identical electrical specifications (10 µF, 250 V, ±20%, 2000 Hrs @ 85°C) and physical dimensions while carrying Active product status. This part is ROHS3 compliant and suitable for new designs.

Same Voltage, Alternative Manufacturer

Frequently Asked Questions (FAQ)

Q: Can UVK2E100MPD be used as a direct replacement?

A: UVK2E100MPD is electrically equivalent (10 µF, 250 V, ±20%, 2000 Hrs @ 85°C) but has a reduced height of 0.551" (14.00 mm) compared to the original 0.689" (17.50 mm). This shorter profile may affect PCB layout compatibility. Verify clearance in your application before substitution.

Q: What is the difference between Rubycon PK and PX series at the same voltage?

A: Both series maintain identical capacitance and voltage ratings. The primary difference is operating temperature range and lifetime rating. PK series operates -40°C ~ 85°C with 2000 Hrs @ 85°C lifetime. PX series extends to -40°C ~ 105°C with 2000 Hrs @ 105°C lifetime, providing enhanced thermal performance.

Q: Is the height increase from 0.689" to 0.709" critical?

A: Height differences of 0.020" (0.50 mm) may impact PCB clearance, particularly in space-constrained designs. Verify available vertical clearance above the capacitor location before selecting parts with increased height (350PK10MEFC10X16, 350PX10MEFC10X16, 400PX10MEFCKC10X16, 450BXW10MEFR10X16).

Q: Why do some substitutes have lower ripple current ratings?

A: Ripple current capability depends on internal construction and thermal design. Lower ripple current ratings indicate reduced current-handling capacity at specified frequencies. Verify that your application's ripple current requirements do not exceed the substitute part's rating.

Q: Are all substitute parts ROHS3 compliant?

A: All listed substitute parts are ROHS3 compliant except where noted. B43821F2106M000 carries REACH Unaffected status. UCY2G100MPD has REACH Affected status. Verify compliance requirements for your specific application and regulatory jurisdiction.

Q: Can I use a 400 V or 450 V part in a 250 V circuit?

A: Yes. Higher voltage-rated capacitors are backward compatible in lower voltage applications. The capacitor will operate safely at voltages below its rating. However, verify that physical dimensions (particularly height) accommodate your PCB layout.

Q: What does "Not For New Designs" mean?

A: This designation indicates the manufacturer has discontinued active support for the part. While existing inventory may be available, the part is not recommended for new product development. Transition to Active status alternatives such as UVR2E100MPD1AA or upgrade options for long-term supply assurance.
