Engineering Selection Recommendations

Both the Nichicon UCS2E470MHD and UCY2E470MHD3 are active production parts with full RoHS3 compliance. The UCY2E470MHD3 provides an extended operational lifetime of 12,000 hours at 105°C versus 10,000 hours for the UCS2E470MHD, while maintaining identical electrical performance and mechanical form factor. Selection between these parts depends on application lifetime requirements and design margin considerations. Both parts are suitable for general-purpose applications requiring 47 µF, 250 V aluminum electrolytic capacitors in through-hole radial configuration.

Frequently Asked Questions (FAQ)

Q: Can the UCY2E470MHD3 be used as a direct replacement for the UCS2E470MHD?

A: Yes. The UCY2E470MHD3 maintains identical capacitance, voltage rating, tolerance, lead spacing, case diameter, height, and mounting configuration. Both parts are through-hole radial cans with 47 µF capacitance and 250 V rating. The substitute part offers extended lifetime at rated temperature.

Q: What is the primary difference between these two parts?

A: The lifetime rating at 105°C differs: UCS2E470MHD is rated for 10,000 hours, while UCY2E470MHD3 is rated for 12,000 hours. All other electrical and mechanical parameters are identical.

Q: Are there any compliance differences between the main part and substitute?

A: Both parts are RoHS3 compliant and carry EAR99 ECCN classification. The UCY2E470MHD3 is REACH Affected, while the UCS2E470MHD is REACH Unaffected. Verify REACH compliance requirements for your specific application and region.

Q: Will the substitute part fit in the same PCB footprint?

A: Yes. Both parts have identical lead spacing of 0.197" (5.00 mm), case diameter of 0.492" (12.50 mm), and seated height of 0.846" (21.50 mm). No PCB layout modifications are required.

Q: What ripple current specifications apply to both parts?

A: Both the UCS2E470MHD and UCY2E470MHD3 are rated for 490 mA ripple current at 120 Hz and 980 mA ripple current at 100 kHz.
