Engineering Selection Recommendations

The UCS2E151MHD is a qualified substitute for the URS2D151MHD in applications where the original part is specified. Both components are Active products with full RoHS3 compliance and identical mechanical interfaces.

The substitute part provides performance enhancements including a 50 V higher voltage rating (250 V vs. 200 V), extended operational lifetime (10000 hours at 105°C vs. 2000 hours at 85°C), and increased ripple current capacity. These characteristics make the UCS2E151MHD suitable for direct replacement in existing designs without PCB modification or re-qualification.

Selection between these parts should be based on application voltage requirements, thermal environment, and ripple current demands. The UCS2E151MHD is appropriate for applications requiring enhanced reliability margins or operation in elevated temperature environments.

Frequently Asked Questions (FAQ)

Q: Can the UCS2E151MHD replace the URS2D151MHD in existing designs?

A: Yes. Both parts share identical mechanical dimensions, lead spacing, and mounting configuration. No PCB layout changes are required for substitution.

Q: What are the key differences between these parts?

A: The primary differences are voltage rating (250 V vs. 200 V), operational lifetime (10000 hours at 105°C vs. 2000 hours at 85°C), and ripple current capacity. Capacitance, tolerance, and physical package remain identical.

Q: Is the higher voltage rating of the UCS2E151MHD a concern for 200 V applications?

A: No. A higher voltage-rated capacitor operates safely in lower voltage applications. The 250 V rating of the substitute provides additional design margin without affecting circuit performance.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the URS2D151MHD and UCS2E151MHD are RoHS3 compliant and REACH unaffected.

Q: What is the lead spacing for these capacitors?

A: Both parts have a lead spacing of 0.295 inches (7.50 mm), ensuring compatibility with existing PCB footprints.

Q: Can these parts be used interchangeably in high-ripple-current applications?

A: The UCS2E151MHD has superior ripple current ratings (970 mA @ 120 Hz and 1.94 A @ 100 kHz) compared to the URS2D151MHD (710 mA @ 120 Hz and 1.136 A @ 10 kHz), making it better suited for applications with elevated ripple current demands.
