Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECE-T2WP821FA is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 820 µF (exact match required)
• Voltage Rating: 450 V (minimum acceptable rating)
• Tolerance: ±20% (electrical performance tolerance)
• ESR Specification: 243 mOhm @ 120 Hz (electrical performance characteristic)
• Lifetime Rating: 3000 Hrs @ 85°C (reliability specification)
• Operating Temperature Range: -25°C ~ 85°C (environmental compatibility)
• Package Type: Radial, Can - Snap-In - 4 Lead (mechanical and electrical interface)
• Physical Dimensions: 1.575" Dia (40.00 mm) and 2.480" Height (63.00 mm) (board layout compatibility)
• Mounting Type: Through Hole (assembly process compatibility)

Substitute parts must match all parameters listed above to ensure functional and mechanical interchangeability without circuit redesign or board modification.
