Engineering Selection Recommendations

UCY2D820MHD1TO is a direct electrical substitute for the UPT2D820MHD1TO. Both parts maintain identical capacitance, voltage rating, tolerance, and physical dimensions. The UCY2D820MHD1TO offers extended operational lifetime (12000 Hrs @ 105°C versus 5000 Hrs), expanded operating temperature range (-40°C to 105°C versus -25°C to 105°C), and increased ripple current capability. Both parts are ROHS3 compliant and active in production. The UCY2D820MHD1TO is suitable for direct replacement in applications where the original part is specified.

UCY2E820MHD9TO is an upgraded substitute with a higher voltage rating of 250 V compared to the 200 V rating of the UPT2D820MHD1TO. This part maintains the same capacitance, tolerance, and physical form factor. The UCY2E820MHD9TO provides 12000 hours lifetime at 105°C and an expanded operating temperature range. Selection of this part is appropriate for applications requiring higher voltage margin or where 250 V rated components are preferred for system reliability. Both parts are ROHS3 compliant and active in production.

Frequently Asked Questions (FAQ)

Q: Can UCY2D820MHD1TO be used as a direct replacement for UPT2D820MHD1TO?

A: Yes. Both parts have identical capacitance (82 µF), voltage rating (200 V), tolerance (±20%), lead spacing (5.00mm), case diameter (12.50mm), and mounting type (through hole radial). The UCY2D820MHD1TO offers improved lifetime and temperature range specifications.

Q: What is the difference between UCY2D820MHD1TO and UCY2E820MHD9TO?

A: The primary difference is voltage rating. UCY2D820MHD1TO is rated at 200 V, while UCY2E820MHD9TO is rated at 250 V. Both have identical capacitance, tolerance, physical dimensions, and lead spacing. The 250 V rating of UCY2E820MHD9TO provides higher voltage margin in the same package.

Q: Are the physical dimensions identical across all three parts?

A: Lead spacing and case diameter are identical (5.00mm and 12.50mm respectively). Height differs slightly: UPT2D820MHD1TO is 27.00mm maximum, while both UCY substitutes are 26.50mm maximum. This 0.50mm difference is within typical PCB layout tolerances for through-hole components.

Q: Do all parts meet RoHS compliance requirements?

A: Yes. UPT2D820MHD1TO, UCY2D820MHD1TO, and UCY2E820MHD9TO are all ROHS3 compliant.

Q: What is the operating temperature range for each part?

A: UPT2D820MHD1TO operates from -25°C to 105°C. Both UCY substitutes operate from -40°C to 105°C, providing extended low-temperature capability.

Q: Which substitute should be selected for maximum ripple current handling?

A: UCY2D820MHD1TO provides the highest ripple current capability at 645 mA @ 120 Hz and 1.29 A @ 100 kHz. UCY2E820MHD9TO provides 615 mA @ 120 Hz and 1.23 A @ 100 kHz. Both exceed the original part's 410 mA @ 120 Hz specification.
