UCS2G100MPD Equivalent & Substitute Parts

Part Overview

The UCS2G100MPD is a 10 µF, 400 V aluminum electrolytic capacitor in radial through-hole configuration, manufactured by Nichicon. This component is rated for 8000 hours at 105°C and is designed for general-purpose applications requiring reliable energy storage and filtering in power supply circuits. The part maintains Active product status with full RoHS3 compliance and REACH unaffected certification. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, application upgrades, or design optimization needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UCS2G100MPD is determined by strict adherence to the following electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Capacitance value must equal 10 µF
• Tolerance must be ±20%
• Voltage rating must be equal to or greater than 400 V
• Operating temperature range must encompass -40°C ~ 105°C
• Polarization must remain Polar

Mechanical Compatibility Criteria:

• Lead spacing must equal 0.197" (5.00mm)
• Diameter must equal 0.394" (10.00mm)
• Height must not exceed 0.846" (21.50mm)
• Mounting type must be Through Hole
• Package configuration must be Radial, Can

Compliance Requirements:

• RoHS3 compliance mandatory
• REACH unaffected status required

The EKXF451ELL100MJ20S from Chemi-Con meets all substitution criteria with identical capacitance, tolerance, mechanical dimensions, and lead spacing. The higher voltage rating (450 V vs. 400 V) and extended lifetime (20000 Hrs vs. 8000 Hrs @ 105°C) provide enhanced performance margins while maintaining full backward compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the UCS2G100MPD and EKXF451ELL100MJ20S maintain Active product status with full RoHS3 compliance and REACH unaffected certification, ensuring regulatory compliance for current and future applications. The EKXF451ELL100MJ20S is electrically and mechanically interchangeable with the UCS2G100MPD in all through-hole PCB applications requiring 10 µF capacitance at 400 V or lower operating voltages. The substitute part's higher voltage rating and extended thermal lifetime provide additional performance margin without introducing any compatibility constraints. Component selection should be based on availability, lead time requirements, and inventory management objectives.

Frequently Asked Questions (FAQ)

Q: Can the EKXF451ELL100MJ20S replace the UCS2G100MPD in existing designs?

A: Yes. The EKXF451ELL100MJ20S is mechanically and electrically compatible. Identical lead spacing (5.00mm), diameter (10.00mm), height (21.50mm), and mounting configuration ensure direct PCB compatibility. The higher voltage rating (450 V) and extended lifetime (20000 Hrs @ 105°C) do not create any reverse compatibility issues.

Q: What are the key differences between these two parts?

A: The primary differences are voltage rating (400 V vs. 450 V) and thermal lifetime (8000 Hrs vs. 20000 Hrs @ 105°C). Both parts share identical capacitance (10 µF), tolerance (±20%), operating temperature range (-40°C ~ 105°C), and mechanical dimensions.

Q: Are both parts suitable for the same applications?

A: Yes. Both parts are rated for general-purpose applications and maintain identical electrical specifications for capacitance, tolerance, and operating temperature. The EKXF451ELL100MJ20S provides enhanced performance margins through higher voltage and extended lifetime ratings.

Q: Do these parts require different PCB footprints?

A: No. Both parts use identical lead spacing (5.00mm) and radial through-hole configuration, requiring no PCB layout modifications for substitution.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the UCS2G100MPD and EKXF451ELL100MJ20S are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.
