Substitute Part Grouping Explanation
Substitution for the UPB1C221MPD is determined by strict adherence to the following electrical and mechanical parameters:
Primary Substitution Criteria:
- Capacitance: 220 µF (exact match required)
- Tolerance: ±20% (exact match required)
- Voltage Rating: 16 V minimum (equal or higher voltage acceptable)
- Polarization: Polar (exact match required)
- Mounting Type: Through Hole (exact match required)
- Package Type: Radial, Can (exact match required)
- Lead Spacing: 0.138" (4.60mm) (exact match required for direct substitution)
- Case Diameter: 0.315" (8.00mm) (exact match required for direct substitution)
- Height: 0.512" (13.00mm) (exact match required for direct substitution)
Secondary Considerations:
- Lifetime @ 105°C: 5000 hours minimum acceptable
- Operating Temperature Range: -40°C ~ 105°C (exact match required)
- Ripple Current Ratings: Must meet or exceed specified values
Substitute parts are categorized as follows:
Direct Substitutes: Identical electrical specifications and physical dimensions. Lead spacing, case diameter, and height match exactly, enabling drop-in replacement without PCB modification.
Upgrade Substitutes: Higher voltage rating (25 V or 35 V) with identical capacitance, tolerance, and physical dimensions. Suitable for applications where voltage headroom is beneficial. All other parameters remain compatible.
Similar Substitutes: Matching capacitance, tolerance, and voltage rating with variations in physical dimensions (lead spacing, case diameter, or height). Require PCB layout verification before implementation.

Engineering Selection Recommendations
Direct Substitution (No PCB Modification Required):
The 16YXM220MEFR8X11.5 from Rubycon is the preferred direct substitute. It maintains identical electrical specifications (220 µF, 16 V, ±20% tolerance) and physical dimensions (lead spacing 0.138", case diameter 0.315", height 0.512"). The part carries Active product status and ROHS3 compliance, with an extended lifetime of 10000 hours at 105°C compared to the original 5000 hours. This part enables drop-in replacement without PCB layout changes.
The 16YXF220MEFC8X11.5 from Rubycon is an alternative direct substitute with identical dimensions and electrical specifications. It carries Not For New Designs status but offers 7000 hours lifetime at 105°C and ROHS3 compliance.
Upgrade Substitution (Same Physical Footprint, Higher Voltage Rating):
For applications requiring increased voltage margin, the following parts maintain identical physical dimensions while providing higher voltage ratings:
- UHV1E221MPD (Nichicon, 25 V): 6000 hours lifetime, ROHS3 compliant
- UHV1V221MPD (Nichicon, 35 V): 6000 hours lifetime, ROHS3 compliant
- 227KBM025M (Cornell Dubilier, 25 V): 7000 hours lifetime, ROHS3 compliant, Active status
- 25YXF220MEFC8X11.5 (Rubycon, 25 V): 7000 hours lifetime, ROHS3 compliant
- 35YXJ220M8X11.5 (Rubycon, 35 V): 7000 hours lifetime, ROHS3 compliant, Active status
- 35YXJ220MCA8X11.5 (Rubycon, 35 V): 7000 hours lifetime, ROHS3 compliant, Active status
These parts are suitable for direct PCB substitution when higher voltage headroom is desired or when the original 16 V rating is marginal for the application.
Similar Substitution (Requires PCB Layout Verification):
The UHV1C221MED (Nichicon, 16 V) and UKL1C221MPDANA (Nichicon, 16 V) match electrical specifications but feature different physical dimensions. These require PCB layout verification before implementation due to variations in lead spacing, case diameter, and height.
Frequently Asked Questions (FAQ)
Q: Can I use a 25 V or 35 V rated capacitor in place of the 16 V UPB1C221MPD?
A: Yes. Higher voltage-rated capacitors with identical capacitance, tolerance, and physical dimensions are suitable substitutes. The 25 V and 35 V variants maintain the same 220 µF capacitance and ±20% tolerance, with identical lead spacing (0.138"), case diameter (0.315"), and height (0.512"). Higher voltage ratings provide additional safety margin in the circuit.
Q: What is the difference between direct and upgrade substitutes?
A: Direct substitutes match all electrical and physical parameters of the original part, including voltage rating. Upgrade substitutes maintain identical capacitance, tolerance, and physical dimensions but feature higher voltage ratings (25 V or 35 V instead of 16 V). Both types are compatible with the original PCB layout.
Q: Why do some substitute parts have different lead spacing or case dimensions?
A: Physical dimension variations (lead spacing, case diameter, height) reflect different product series or manufacturing standards. Parts with different dimensions require PCB layout verification to confirm compatibility with existing through-hole pad spacing and clearance requirements.
Q: What does "Not For New Designs" product status mean?
A: Parts marked "Not For New Designs" are still available and functional but are not recommended for new product development. They may be used for maintenance, repair, or legacy system support. For new designs, parts with Active status are preferred.
Q: Are all substitute parts ROHS3 compliant?
A: The original UPB1C221MPD is REACH Unaffected. Most substitute parts listed carry ROHS3 compliance. Verify compliance requirements for your specific application before selection.
Q: What is the significance of lifetime ratings (5000 Hrs, 6000 Hrs, 7000 Hrs, 10000 Hrs)?
A: Lifetime ratings indicate the expected operational duration at maximum rated temperature (105°C) before capacitance degradation reaches specified limits. Higher lifetime ratings indicate greater reliability and longer service life under thermal stress. The original part specifies 5000 hours; substitutes with equal or higher ratings are acceptable.
Q: Can I substitute a part with different ripple current ratings?
A: Ripple current ratings must meet or exceed the application requirements. Substitutes with higher ripple current ratings provide additional margin for AC current handling. Verify that the substitute part's ripple current specifications match or exceed the circuit requirements.
