Key Parameters

Substitute Part Grouping Explanation

Substitution of the UPS2A010MDD is determined by strict equivalence across the following parameters:

• Capacitance value: 1 µF (exact match required)
• Voltage rating: 100 V (minimum acceptable)
• Tolerance: ±20% (electrical performance band)
• Lifetime rating: 2000 Hrs @ 105°C (thermal endurance specification)
• Operating temperature range: -55°C ~ 105°C (environmental compatibility)
• Polarization: Polar (circuit requirement)
• Package: Radial, Can (mechanical and electrical interface)
• Mounting: Through Hole (PCB assembly compatibility)
• Lead spacing: 0.079" (2.00mm) (footprint requirement)
• Physical dimensions: 0.197" Dia × 0.492" Height (board space constraint)

The substitute part 105KXM100M meets all these criteria and is therefore classified as a parametric equivalent.
