Substitute Part Grouping Explanation

Substitution of the UVY2A331MHD1TO is determined by strict equivalence across the following critical parameters:

• Capacitance value: 330 µF (exact match required)
• Rated voltage: 100 V (exact match required)
• Tolerance: ±20% (exact match required)
• Thermal rating: 2000 Hrs @ 105°C (exact match required)
• Operating temperature range: -55°C ~ 105°C (exact match required)
• Ripple current specifications: 540 mA @ 120 Hz and 810 mA @ 10 kHz (exact match required)
• Package configuration: Radial, Can with 0.197" (5.00 mm) lead spacing (exact match required)
• Mounting type: Through Hole (exact match required)
• Compliance: ROHS3 Compliant (exact match required)

The UVZ2A331MHD1TO meets all substitution criteria as a parametric equivalent from the same manufacturer.
