UEP0J102MPD Equivalent & Substitute Parts

Part Overview

The UEP0J102MPD is a 1000 µF, 6.3 V aluminum electrolytic capacitor in radial configuration manufactured by Nichicon. This component is rated for 1000 hours at 105°C and is designed for general-purpose applications requiring through-hole mounting. The part is marked as "Not For New Designs," indicating it has been superseded in Nichicon's product line. Finding equivalent or substitute parts is necessary for maintenance, repair, and legacy system support where original components are unavailable or inventory is depleted.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the UEP0J102MPD is determined by the following critical parameters:

• Capacitance Value: Must be 1000 µF (exact match required)
• Voltage Rating: Minimum 6.3 V; higher voltage ratings are acceptable for direct substitution
• Tolerance: ±20% (standard tolerance for general-purpose aluminum electrolytic capacitors)
• Polarization: Bi-Polar configuration
• Physical Dimensions: Lead spacing 0.197" (5.00 mm) and diameter 0.394" (10.00 mm) for PCB compatibility
• Mounting Type: Through Hole radial configuration
• Temperature Rating: Operating range -55°C ~ 105°C with 1000-hour lifetime at 105°C
• Compliance: ROHS3 compliant

The substitute part 10NXA1000MEFC10X20 (Rubycon NXA series) meets all substitution criteria with an upgraded voltage rating of 10 V, which provides additional design margin while maintaining identical physical footprint and electrical characteristics.

Engineering Selection Recommendations

The 10NXA1000MEFC10X20 (Rubycon NXA series) is a direct substitute for the UEP0J102MPD. The substitute part offers the following advantages:

• Active Product Status: The Rubycon part is in active production, ensuring long-term availability and supply chain stability compared to the Nichicon part marked "Not For New Designs."
• Voltage Upgrade: The 10 V rating provides additional safety margin over the original 6.3 V specification, reducing stress on the component in typical operating conditions.
• Identical Physical Footprint: Both parts share the same lead spacing (5.00 mm) and diameter (10.00 mm), enabling direct PCB mounting without layout modifications.
• Compliance Alignment: Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.
• Thermal Performance: Both parts maintain 1000-hour lifetime at 105°C with identical operating temperature range (-55°C ~ 105°C).

Frequently Asked Questions (FAQ)

Q: Can the 10NXA1000MEFC10X20 be used as a direct replacement for the UEP0J102MPD?

A: Yes. Both parts have identical capacitance (1000 µF), tolerance (±20%), physical dimensions (10.00 mm diameter, 5.00 mm lead spacing), and thermal ratings (1000 Hrs @ 105°C). The substitute has a higher voltage rating (10 V vs. 6.3 V), which is acceptable for direct substitution and provides additional design margin.

Q: What is the difference in ripple current handling between these parts?

A: The UEP0J102MPD handles 460 mA ripple current at 120 Hz, while the 10NXA1000MEFC10X20 handles 378 mA at 120 Hz. For applications requiring high ripple current at low frequencies, verify that the substitute's ripple current specification meets circuit requirements.

Q: Are there any physical installation differences?

A: The substitute part is 0.02" (0.50 mm) shorter in seated height (21.50 mm vs. 22.00 mm). This minor difference does not affect PCB mounting or clearance in standard through-hole applications.

Q: Why is the original part marked "Not For New Designs"?

A: This designation indicates that Nichicon has discontinued active development and promotion of the UEP series. The substitute part from Rubycon's active NXA series is recommended for new applications and ongoing production support.

Q: Are both parts compliant with current environmental standards?

A: Yes. Both the UEP0J102MPD and 10NXA1000MEFC10X20 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.
