UPX1C221MPD Equivalent & Substitute Parts

Part Overview

The UPX1C221MPD is a 220 µF, 16 V aluminum electrolytic capacitor in radial through-hole configuration, manufactured by Nichicon under the UPX series. This component is rated for 20,000 hours at 105°C and is designed for general-purpose applications requiring stable capacitance and reliable performance across industrial temperature ranges.

The UPX1C221MPD is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for systems utilizing this component.

Substitute Part Grouping Explanation

Substitution of the UPX1C221MPD is determined by the following critical parameters:

Capacitance Value: 220 µF (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Mounting Type: Through Hole (exact match required)
Package Type: Radial, Can (exact match required)
Physical Dimensions: Lead spacing 0.197" (5.00 mm), diameter 0.394" (10.00 mm), height 0.689" (17.50 mm) (exact match required for PCB compatibility)
Operating Temperature Range: -55°C to 105°C (exact match required)
Voltage Rating: 16 V minimum (equal or higher voltage rating is acceptable)

The RF1H221MP51016E qualifies as a substitute because it matches all critical mechanical and electrical parameters. The substitute part features a higher voltage rating (50 V vs. 16 V), which is permissible in substitution applications as higher-rated components operate safely at lower voltages.

Engineering Selection Recommendations

The RF1H221MP51016E is a direct mechanical and electrical substitute for the obsolete UPX1C221MPD. Both components are ROHS3 compliant and operate across the identical temperature range. The substitute part is currently in active production status, ensuring long-term availability and supply chain stability.

The RF1H221MP51016E features a higher voltage rating (50 V) and improved ripple current handling capability at high frequencies (1.37 A vs. 504 mA at 100 kHz). These characteristics provide enhanced performance margins in the target application. The substitute part has a lower rated lifetime at 105°C (10,000 hours vs. 20,000 hours); this difference should be evaluated against the specific thermal and operational profile of the application.

Both components share identical physical dimensions and lead spacing, ensuring direct PCB compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the RF1H221MP51016E be used as a direct replacement for the UPX1C221MPD?

A: Yes. Both components have identical capacitance (220 µF), tolerance (±20%), voltage rating compatibility (50 V rated vs. 16 V required), physical dimensions, lead spacing, and mounting configuration. PCB layout and component placement require no modification.

Q: Why does the substitute part have a higher voltage rating?

A: Higher voltage-rated capacitors operate safely at lower voltages. The 50 V rating of the RF1H221MP51016E provides additional performance margin and is acceptable for applications requiring 16 V operation.

Q: What is the difference in lifetime specifications?

A: The UPX1C221MPD is rated for 20,000 hours at 105°C, while the RF1H221MP51016E is rated for 10,000 hours at 105°C. The application's thermal profile and expected operational duration should be evaluated to determine if this difference impacts system reliability requirements.

Q: Are there packaging differences between these parts?

A: The UPX1C221MPD is supplied in bulk packaging, while the RF1H221MP51016E is supplied in cut tape (CT) packaging. Both are through-hole components with identical physical form factors.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the UPX1C221MPD and RF1H221MP51016E are ROHS3 compliant and carry EAR99 ECCN classification.
