UEP1C221MPD Equivalent & Substitute Parts

Part Overview

The UEP1C221MPD is a 220 µF, 16 V aluminum electrolytic capacitor in radial configuration manufactured by Nichicon. This component is classified as Not For New Designs, indicating it has been superseded in Nichicon's product portfolio. The part delivers 1000 hours of operational life at 105°C and is suitable for general-purpose applications requiring through-hole mounting.

Finding equivalent or substitute parts becomes necessary when the original UEP1C221MPD reaches end-of-life status, inventory depletion, or when design flexibility permits selection of functionally compatible alternatives that meet or exceed the original specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the UEP1C221MPD is determined by strict equivalence in the following parameters:

• Capacitance Value: 220 µF (exact match required)
• Tolerance: ±20% (matching tolerance band)
• Polarization: Bi-Polar configuration
• Lead Spacing: 0.197" (5.00 mm) for PCB compatibility
• Package Dimensions: 0.394" Dia × 0.551" Height (10.00 mm × 14.00 mm) for mechanical fit
• Mounting Type: Through Hole radial configuration
• Operating Temperature Range: -55°C ~ 105°C minimum
• Lifetime Rating: 1000 Hrs @ 105°C minimum

The substitute part 25NXA220MEFC10X12.5 meets all these criteria. The rated voltage of 25 V on the substitute exceeds the original 16 V specification, providing enhanced voltage margin without affecting form factor or electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 25NXA220MEFC10X12.5 from Rubycon is a direct functional substitute for the UEP1C221MPD. The substitute part carries Active product status, ensuring continued availability and supply chain stability compared to the Not For New Designs status of the original part.

Both components maintain ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for equivalent applications. The higher voltage rating (25 V vs. 16 V) on the substitute provides additional design margin without introducing mechanical or electrical incompatibility.

Selection of the substitute part is appropriate for applications where the original UEP1C221MPD is no longer available or where design refresh permits component modernization while maintaining circuit performance.

Frequently Asked Questions (FAQ)

Q: Can the 25NXA220MEFC10X12.5 be used as a direct replacement for the UEP1C221MPD?

A: Yes. Both parts share identical capacitance (220 µF), tolerance (±20%), physical dimensions (10.00 mm diameter × 14.00 mm height), lead spacing (5.00 mm), and operating temperature range (-55°C ~ 105°C). The substitute's 25 V rating exceeds the original 16 V specification, providing enhanced voltage margin.

Q: Are there any mechanical compatibility concerns?

A: No. Both components use identical radial, can-style packaging with matching lead spacing and seated height. PCB footprints and mounting procedures remain unchanged.

Q: What is the significance of the higher voltage rating on the substitute?

A: The 25 V rating on the 25NXA220MEFC10X12.5 provides additional voltage headroom in the circuit. This does not affect capacitance value or physical form factor and is compatible with circuits designed for 16 V operation.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the UEP1C221MPD and 25NXA220MEFC10X12.5 are ROHS3 compliant and REACH Unaffected, satisfying equivalent regulatory requirements.

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

A: This designation indicates the UEP1C221MPD has been superseded in Nichicon's product line. For new designs or component refresh cycles, the Rubycon substitute offers equivalent functionality with Active product status and assured long-term availability.
