Substitute Part Grouping Explanation

Substitution of the UVZ1C333MRD is determined by strict equivalence across the following electrical and mechanical parameters:

• Capacitance Value: 33000 µF (exact match required)
• Voltage Rating: 16 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime Rating: 2000 Hrs @ 105°C (exact match required)
• Operating Temperature Range: -55°C ~ 105°C (exact match required)
• Ripple Current Specifications: 3.45 A @ 120 Hz and 3.9675 A @ 10 kHz (exact match required)
• Physical Dimensions: 0.984" Dia (25.00 mm), Height 2.047" (52.00 mm), Lead Spacing 0.492" (12.50 mm) (exact match required)
• Package Type: Radial, Can, Through Hole (exact match required)
• Polarization: Polar (exact match required)
• Compliance: ROHS3 Compliant, REACH Unaffected (exact match required)

The UVY1C333MRD meets all substitution criteria as a parametric equivalent to the UVZ1C333MRD.
