• Capacitance Value: 4.7 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating: 35 V (exact match required)
• Type: Conformal Coated (exact match required)
• ESR: 3 Ohm (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Physical Dimensions: 0.217" Dia (5.50mm), Height 0.402" (10.20mm), Lead Spacing 0.200" (5.08mm) (exact match required)
• Series: T356, UltraDip II (exact match required)

The T356E475K035AT meets all substitution criteria and is classified as a direct equivalent within the same manufacturer series.
