Engineering Selection Recommendations

Both the UCS2W150MHD1TO and UCY2H150MHD1TO are active products manufactured by Nichicon and maintain ROHS3 compliance. The UCY2H150MHD1TO offers the following advantages over the main part:

Higher voltage rating (500 V vs. 450 V) provides additional safety margin in applications with voltage transients or tolerance stack-up
Extended operational lifetime (12000 Hrs vs. 10000 Hrs @ 105°C) supports longer system reliability requirements
Wider operating temperature range (-40°C to 105°C vs. -25°C to 105°C) accommodates cold-environment applications

Selection between these parts depends on application voltage requirements and thermal operating conditions. The UCS2W150MHD1TO remains suitable for standard 450 V applications. The UCY2H150MHD1TO is appropriate when higher voltage margin or extended lifetime is required.

Frequently Asked Questions (FAQ)

Q: Can the UCY2H150MHD1TO be used as a direct replacement for the UCS2W150MHD1TO on existing PCBs?

A: Yes. Both parts share identical mechanical dimensions (lead spacing, case diameter, height) and mounting type (through-hole radial). PCB footprints and assembly processes require no modification.

Q: What is the impact of the higher 500 V rating on the UCY2H150MHD1TO?

A: The higher voltage rating does not negatively affect circuit operation. In a 450 V application, the UCY2H150MHD1TO operates within its rated specifications with additional voltage margin. No circuit redesign is required.

Q: Are there differences in ripple current handling between these parts?

A: The UCY2H150MHD1TO has lower ripple current ratings (220 mA @ 120 Hz and 440 mA @ 100 kHz) compared to the UCS2W150MHD1TO (300 mA @ 120 Hz and 600 mA @ 100 kHz). Applications with high ripple current requirements should verify that the substitute part meets the circuit's ripple current specifications.

Q: What does the extended temperature range of the UCY2H150MHD1TO provide?

A: The UCY2H150MHD1TO operates from -40°C to 105°C, compared to -25°C to 105°C for the UCS2W150MHD1TO. This extended lower temperature limit supports applications in cold environments or equipment with wide ambient temperature requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both the UCS2W150MHD1TO and UCY2H150MHD1TO are ROHS3 compliant and suitable for applications with RoHS requirements.
