Substitute Part Grouping Explanation

The UCY2D680MHD3 qualifies as a direct substitute for the UCS2D680MHD based on the following critical parameters:

• Capacitance: 68 µF (identical)
• Voltage Rating: 200 V (identical)
• Tolerance: ±20% (identical)
• Operating Temperature Range: -40°C ~ 105°C (identical)
• Ripple Current @ 120 Hz: 650 mA (identical)
• Ripple Current @ 100 kHz: 1.3 A (identical)
• Lead Spacing: 0.197" (5.00 mm) (identical)
• Size / Dimension: 0.492" Dia (12.50 mm) (identical)
• Package / Case: Radial, Can (identical)
• Mounting Type: Through Hole (identical)
• Polarization: Polar (identical)

The UCY2D680MHD3 offers an extended lifetime rating of 12000 hours at 105°C compared to the 10000 hours of the UCS2D680MHD, with a reduced maximum seated height of 0.787" (20.00 mm) versus 0.846" (21.50 mm).

Parameter Comparison

Engineering Selection Recommendations

Both the UCS2D680MHD and UCY2D680MHD3 are active production parts from Nichicon with identical ROHS3 compliance and REACH unaffected status. The UCY2D680MHD3 provides extended operational lifetime (12000 hours versus 10000 hours at 105°C) and a reduced maximum seated height, making it suitable for applications with space constraints or requiring enhanced reliability margins. Both parts maintain identical electrical performance across all specified ripple current ratings and operating temperature ranges. Selection between these parts depends on application-specific requirements for component longevity and physical space availability on the printed circuit board.

Frequently Asked Questions (FAQ)

Q: Can UCY2D680MHD3 be used as a direct replacement for UCS2D680MHD?

A: Yes. Both parts share identical capacitance (68 µF), voltage rating (200 V), tolerance (±20%), operating temperature range (-40°C to 105°C), ripple current specifications, lead spacing (5.00 mm), and package configuration (radial, can, through-hole). The reduced maximum seated height of the UCY2D680MHD3 (20.00 mm versus 21.50 mm) is compatible with applications designed for the UCS2D680MHD.

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

A: The UCY2D680MHD3 offers an extended lifetime rating of 12000 hours at 105°C compared to 10000 hours for the UCS2D680MHD. Additionally, the UCY2D680MHD3 has a maximum seated height of 0.787" (20.00 mm) versus 0.846" (21.50 mm) for the UCS2D680MHD.

Q: Are both parts compliant with environmental regulations?

A: Yes. Both the UCS2D680MHD and UCY2D680MHD3 are ROHS3 compliant and REACH unaffected, meeting current environmental standards for electronic components.

Q: Will the reduced height of UCY2D680MHD3 affect circuit board layout?

A: No. The reduced maximum seated height of the UCY2D680MHD3 (20.00 mm) is a beneficial characteristic that provides additional clearance on the printed circuit board compared to the UCS2D680MHD (21.50 mm). This does not create compatibility issues and may improve board layout flexibility.

Q: Are the electrical performance characteristics identical?

A: Yes. Both parts maintain identical ripple current ratings at 120 Hz (650 mA) and 100 kHz (1.3 A), identical lead spacing (5.00 mm), and identical diameter (12.50 mm). Electrical performance in general purpose applications is equivalent.
