Substitute Part Grouping Explanation
Substitution eligibility is determined by the following criteria:
Direct Substitutes (Same Voltage Rating - 16V):
- UPJ1C221MPD, UPS1C221MPD, UHV1C221MED, and 16YXF220MEFC8X11.5 maintain the 16 V voltage rating with identical capacitance, tolerance, lead spacing, case diameter, and height. These parts are interchangeable at the board level.
Upgraded Substitutes (Higher Voltage Rating - 25V or 35V):
- UHD1E221MPD, UHV1E221MPD, UKA1E221MPD, and UPM1C221MPD operate at 25 V, providing voltage margin above the original 16 V specification. These are electrically compatible in circuits designed for 16 V operation.
- UHV1V221MPD and UKA1V221MPD operate at 35 V, offering additional voltage headroom. These maintain identical physical dimensions and lead spacing.
Audio-Grade Alternatives (Extended Temperature Range):
- UKA1E221MPD and UKA1V221MPD are audio-grade components with extended operating temperature range (-55°C ~ 105°C) compared to the standard -40°C ~ 105°C range.
Automotive-Grade Alternative:
- UPM1C221MPD carries AEC-Q200 qualification for automotive applications while maintaining 16 V rating and identical physical form factor.
All substitute parts share identical lead spacing (0.138"), case diameter (0.315"), and height (0.512"), ensuring direct PCB compatibility without layout modifications.

Engineering Selection Recommendations
For Direct Replacement (Same Voltage, Same Form Factor): Select UPS1C221MPD or UPJ1C221MPD for applications requiring identical electrical and mechanical specifications. Both maintain 220 µF capacitance, 16 V rating, and through-hole radial package with 0.138" lead spacing. UPJ1C221MPD offers extended lifetime (3000 hours vs. 2000 hours) and extended temperature range (-55°C to 105°C).
For Voltage-Upgraded Applications: UHD1E221MPD, UHV1E221MPD, UHV1V221MPD, UKA1E221MPD, and UKA1V221MPD are suitable where circuit design permits higher voltage ratings. These parts provide voltage margin and are electrically backward-compatible in 16 V circuits. UHV1E221MPD and UHV1V221MPD offer extended lifetime ratings (6000 hours at 105°C).
For Automotive Applications: UPM1C221MPD carries AEC-Q200 qualification and is suitable for automotive-grade designs. It maintains 16 V rating, 220 µF capacitance, and identical physical dimensions.

Frequently Asked Questions (FAQ)
Q: Can UHD1E221MPD or UHV1E221MPD replace UHC1C221MPD directly on the PCB? A: Yes. Both parts maintain identical lead spacing (0.138"), case diameter (0.315"), and height (0.512"), ensuring direct PCB compatibility. The higher voltage rating (25 V vs. 16 V) is electrically compatible in circuits designed for 16 V operation.
Q: What is the difference between UPJ1C221MPD and UPS1C221MPD? A: Both are 16 V, 220 µF radial capacitors with identical physical dimensions. UPJ1C221MPD offers 3000-hour lifetime at 105°C compared to UPS1C221MPD's 2000 hours. UPJ1C221MPD has a slightly shorter seated height (0.492" vs. 0.512"). Both support extended temperature range (-55°C ~ 105°C).
Q: Is UHV1C221MED a suitable substitute? A: UHV1C221MED maintains 16 V rating and 220 µF capacitance with identical lead spacing and case diameter. However, it has different lead spacing (0.098" vs. 0.138") and smaller case diameter (0.248" vs. 0.315"), requiring PCB layout modification. It is not a direct drop-in replacement.
Q: Why would I choose a 25 V or 35 V rated capacitor over the original 16 V part? A: Higher voltage ratings provide design margin and improved reliability in circuits with voltage transients or ripple. They are electrically compatible in 16 V applications and often offer extended lifetime ratings (up to 6000 hours at 105°C).
Q: Is UPM1C221MPD suitable for non-automotive applications? A: Yes. UPM1C221MPD is AEC-Q200 qualified for automotive use but is fully functional in general-purpose applications. It maintains 16 V rating, 220 µF capacitance, and identical form factor to the original part.
Q: What is the advantage of the Rubycon 16YXF220MEFC8X11.5? A: This part offers the highest lifetime rating (7000 hours at 105°C) among available substitutes while maintaining 16 V rating and identical physical dimensions. It is suitable for applications
