Substitute Part Grouping Explanation

Substitution eligibility for the UVK2C680MHD1TO is determined by the following critical parameters:

Capacitance: Must be 68 µF (exact match required)
Voltage Rating: Minimum 160 V (equal or higher acceptable)
Tolerance: ±20% (as specified)
Polarization: Polar (required)
Package Type: Radial, Can (mechanical compatibility)
Lead Spacing: 0.197" (5.00 mm) (PCB layout compatibility)

Engineering Selection Recommendations

UCS2C680MHD1TO (160 V variant): This part provides a direct upgrade path from the UVK2C680MHD1TO while maintaining the same 160 V voltage rating. The UCS series is Active and REACH Unaffected, offering extended lifetime (10000 Hrs @ 105°C) and expanded operating temperature range (-40°C to 105°C). This option is suitable for designs requiring compliance with REACH regulations without voltage rating changes.

UCS2D680MHD1TO (200 V variant): This part offers both voltage margin improvement (200 V rating) and enhanced reliability characteristics. The UCS series Active status and REACH Unaffected compliance make it appropriate for applications where additional voltage headroom is beneficial. The 10000-hour lifetime at 105°C provides significant reliability improvement over the original part.

UCY2C680MHD3TO (160 V variant): This part delivers the highest lifetime rating (12000 Hrs @ 105°C) while maintaining the 160 V voltage specification. The UCY series is Active but REACH Affected. This option is optimal for applications prioritizing extended operational life and maximum temperature capability.

UCY2D680MHD3TO (200 V variant): This part combines the highest lifetime rating (12000 Hrs @ 105°C) with elevated voltage rating (200 V). The UCY series Active status and REACH Affected compliance make it suitable for demanding applications requiring both voltage margin and extended service life.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a higher voltage rating than the original UVK2C680MHD1TO?

A: Yes. A higher voltage rating (200 V instead of 160 V) is electrically compatible and provides additional safety margin. The substitute parts UCS2D680MHD1TO and UCY2D680MHD3TO both offer 200 V ratings and maintain all other critical parameters including capacitance, tolerance, package type, and lead spacing.

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

A: Both series are Active alternatives to the obsolete UVK series. The primary difference is lifetime rating: UCS series provides 10000 hours at 105°C, while UCY series provides 12000 hours at 105°C. Both offer extended operating temperature ranges (-40°C to 105°C) compared to the original part (-40°C to 85°C).

Q: Are all substitute parts mechanically compatible with the original PCB layout?

A: Yes. All substitute parts maintain identical lead spacing (0.197" / 5.00 mm), diameter (0.492" / 12.50 mm), and Through Hole mounting type. The maximum seated height of substitute parts (0.846" / 21.50 mm) is slightly less than the original (0.866" / 22.00 mm), ensuring mechanical compatibility without clearance issues.

Q: What is the significance of REACH status in the comparison?

A: REACH Unaffected status (UCS series) indicates the part is not subject to REACH regulatory restrictions. REACH Affected status (UCY series) indicates the part may contain substances of concern under REACH regulations. Selection depends on application regulatory requirements and supply chain compliance obligations.

Q: Can I substitute the UVK2C680MHD1TO with a part having different capacitance or tolerance values?

A: No. Capacitance and tolerance are critical electrical parameters. All listed substitutes maintain 68 µF capacitance and ±20% tolerance to ensure functional equivalence in the circuit.
