• Voltage Rating: 450 V (exact match required)
• Tolerance: ±20% (exact match required)
• ESR @ 100Hz: 31 mOhm (exact match required)
• Lifetime @ 85°C: 20000 Hrs (exact match required)
• Ripple Current @ 100 Hz: 17.9 A (exact match required)
• Ripple Current @ 10 kHz: 25.3 A (exact match required)

Mechanical Parameters:

• Lead Spacing: 31.80 mm (exact match required)
• Diameter: 77.00 mm (exact match required)
• Height - Seated (Max): 148.00 mm (exact match required)
• Package Type: Radial, Can - Screw Terminals (exact match required)
• Mounting Type: Chassis Mount (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)
• Polarization: Polar (exact match required)

The substitute part ALS70A752NP450 meets all specified criteria and is therefore classified as a parametric equivalent.
