Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UCS2D680MHD1TO is determined by strict equivalence across the following critical parameters:

• Capacitance: 68 µF (exact match required)
• Voltage Rating: 200 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Lead Spacing: 0.197" (5.00 mm) (exact match required)
• Physical Dimensions: 0.492" Dia × 0.846" Height (exact match required)
• Mounting Type: Through Hole, Radial configuration (exact match required)
• Package / Case: Radial, Can (exact match required)

The UCY2D680MHD3TO qualifies as a direct substitute based on full alignment with these parameters. The substitute part demonstrates enhanced operational characteristics through an extended lifetime rating of 12000 hours at 105°C compared to the original 10000 hours, while maintaining identical electrical specifications and mechanical compatibility.
