Substitute Part Grouping Explanation

Substitution of the UVR2C470MHD1TO is determined by the following critical parameters:

Electrical Compatibility: Capacitance value (47 µF) and tolerance (±20%) must remain constant. Voltage rating must be equal to or greater than 160 V to maintain circuit safety margins.

Mechanical Compatibility: Lead spacing (5.00 mm) and package diameter (12.50 mm) must match for PCB footprint compatibility. Package height variation within 0.02" (0.50 mm) is acceptable for through-hole radial mounting.

Thermal & Reliability: Operating temperature range must encompass the application's requirements. Lifetime rating at temperature determines long-term reliability; higher ratings provide extended service life.

Regulatory Compliance: RoHS3 compliance is maintained across all substitute options.

The substitute parts are grouped into two categories:

Direct Substitutes (Same Series Lineage): UVR2D470MHD1TO maintains identical electrical and thermal characteristics while offering 200 V rating.

Performance Upgrades (Enhanced Specifications): UCY and UCS series parts provide higher voltage ratings (200 V or 250 V), extended lifetime (10,000–12,000 hours at 105°C), and elevated maximum operating temperature (105°C), enabling use in more demanding thermal environments.

Engineering Selection Recommendations

For Direct Replacement (Same Thermal Profile): UVR2D470MHD1TO or UVK2D470MHD1TO are suitable when the application operates within -40°C to 85°C and requires 2000-hour lifetime at 85°C. Both maintain identical thermal and mechanical characteristics to the original UVR2C470MHD1TO while offering increased voltage margin (200 V vs. 160 V).

For Enhanced Reliability (Active Product Status): UCY2D470MHD3TO and UCS2D470MHD1TO are recommended for new designs or systems requiring extended operational life. Both provide 200 V rating, support operation to 105°C, and deliver significantly higher lifetime ratings (12,000 and 10,000 hours respectively at 105°C). These parts are classified as Active products, ensuring continued availability and manufacturing support.

For Maximum Voltage Margin: UCY2E470MHD3TO and UCS2E470MHD1TO provide 250 V rating with the same enhanced thermal and lifetime characteristics, suitable for applications with elevated voltage stress or thermal cycling requirements.

Compliance Consideration: All substitute parts maintain ROHS3 compliance. UCY series parts are REACH Affected; UCS and UVK series parts are REACH Unaffected. Select based on supply chain compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can UVR2C470MHD1TO be replaced with a higher voltage-rated part?

A: Yes. The UCY and UCS series parts rated at 200 V or 250 V are electrically compatible substitutes. Higher voltage ratings provide additional safety margin without affecting circuit function, as the capacitor will operate at the same voltage stress as the original 160 V design.

Q: What is the difference between UCY and UCS series substitutes?

A: Both series offer 47 µF capacitance with 200 V or 250 V ratings and support 105°C operation. UCY series provides 12,000-hour lifetime at 105°C; UCS series provides 10,000-hour lifetime at 105°C. Both are mechanically compatible with identical lead spacing and package diameter. UCY is REACH Affected; UCS is REACH Unaffected.

Q: Are the UCY and UCS parts physically interchangeable?

A: Yes. All substitute parts maintain 0.197" (5.00 mm) lead spacing and 0.492" (12.50 mm) package diameter. Package height varies slightly (0.846" for UCY/UCS vs. 0.866" for UVR/UVK), but this 0.020" difference is within acceptable tolerance for through-hole radial mounting on standard PCB layouts.

Q: Why is the original UVR2C470MHD1TO marked "Not For New Designs"?

A: This designation indicates the part has been superseded by newer product lines offering improved performance characteristics, such as extended lifetime and higher temperature operation. For new designs, UCY or UCS series parts are recommended.

Q: Can I use a 160 V substitute instead of upgrading to 200 V or 250 V?

A: The UVR2C470MHD1TO itself is the only 160 V option in this substitution group. If 160 V rating is required, the original part must be sourced. However, using a higher-rated substitute (200 V or 250 V) provides improved reliability margins and is the preferred engineering practice.

Q: What ripple current specifications apply to the substitute parts?

A: Ripple current capacity varies by series. UVR and UVK series (2000-hour lifetime at 85°C) support 270 mA @ 120 Hz and 432 mA @ 10 kHz. UCY and UCS series (10,000–12,000-hour lifetime at 105°C) support 490 mA @ 120 Hz and 980 mA @ 100 kHz, providing significantly higher ripple current handling.
