Engineering Selection Recommendations

For Direct PCB Replacement (Preferred): UCS2W220MHD is the manufacturer-recommended substitute. It maintains identical lead spacing (0.295" / 7.50mm) and case diameter (0.630" / 16.00mm) as the original UPJ2F220MHD, enabling direct PCB mounting without layout modifications. This part carries Active product status with ROHS3 compliance, 450 V voltage rating (exceeding the original 315 V), and extended lifetime of 10000 hours at 105°C. Operating temperature range is -25°C to 105°C, which covers the original -40°C minimum with a 15°C reduction in cold-temperature capability.

For Enhanced Reliability: 226KFM450M from Cornell Dubilier / Illinois Capacitor provides equivalent electrical performance with Active product status, 450 V rating, and 10000-hour lifetime. This part maintains the original lead spacing and case diameter with full -40°C to 105°C operating range. Height is 1.063" (27.00mm), representing a 0.020" (0.50mm) increase over the original. ROHS3 compliance and EAR99 classification are maintained.

For Voltage-Matched Substitution: UPJ2V220MHD1TN maintains the original 22 µF capacitance, ±20% tolerance, and identical physical dimensions (lead spacing, case diameter, height). Voltage rating increases to 350 V with equivalent -40°C to 105°C operating range. Product status is Not For New Designs; this option is suitable for legacy system support where voltage margin improvement is desired without changing physical footprint.

For Compact Form Factor: UPW2F220MHD and UVZ2F220MHD offer reduced physical dimensions (0.197" lead spacing, 0.492" case diameter) while maintaining 315 V rating and -40°C to 105°C operating range. These options require PCB layout modification due to different lead spacing and case size. UPW2F220MHD provides 7000-hour lifetime; UVZ2F220MHD provides 2000-hour lifetime. Both carry Obsolete or Not For New Designs status.

Frequently Asked Questions (FAQ)

Q: Can UCS2W220MHD directly replace UPJ2F220MHD without PCB modification? A: Yes. Both parts share identical lead spacing (0.295" / 7.50mm) and case diameter (0.630" / 16.00mm). The UCS2W220MHD is 0.197" (5.00mm) shorter in height, which presents no compatibility issue for through-hole mounting. No PCB layout changes are required.

Q: What is the primary advantage of UCS2W220MHD over the original UPJ2F220MHD? A: UCS2W220MHD offers three improvements: Active product status (versus Obsolete), doubled lifetime rating (10000 hours versus 5000 hours at 105°C), and higher voltage rating (450 V versus 315 V). These enhancements provide better long-term availability and system reliability.

Q: Does UCS2W220MHD operate at -40°C like the original part? A: UCS2W220MHD operates from -25°C to 105°C, compared to the original -40°C to 105°C range. The lower temperature limit is 15°C higher. For applications requiring -40°C operation, UPJ2V220MHD1TN or 226KFM450M maintain the full -40°C to 105°C range.

Q: Why do UPW2F220MHD and UVZ2F220MHD have different lead spacing? A: These parts use 0.197" (5.00mm) lead spacing versus the original 0.295" (7.50mm). This represents a different mechanical design series within Nichicon's product line. PCB footprint modification is required for these substitutes.

Q: Is 226KFM450M from a different manufacturer compatible? A: Yes. 226KFM450M from Cornell Dubilier / Illinois Capacitor meets all electrical and mechanical compatibility criteria: 22 µF capacitance, ±20% tolerance, 450 V rating, -40°C to 105°C operating range, identical lead spacing and case diameter, and ROHS3 compliance. Cross-manufacturer substitution is valid when specifications align.

Q: What does "Not For New Designs" product status mean? A: Parts marked "Not For New Designs" are still manufactured and available but are not recommended for new product development. They are suitable for legacy system support, repair, and replacement applications where the specific part number is already in use.

Q: Can I use a substitute with higher voltage rating in a 315 V circuit? A: Yes. A capacitor rated for 450 V can be used in a 315 V circuit. Higher voltage rating provides additional safety margin and does not degrade performance. The capacitor will operate within its rated specifications.

Q: Does the height difference between substitutes affect circuit performance? A: Height differences do not affect electrical performance. Physical height is a mechanical consideration for PCB assembly, component clearance, and enclosure fit. Verify that the substitute height accommodates your mechanical constraints.
