Substitute Part Grouping Explanation

Substitution eligibility for the B43540B9477M080 is determined by strict alignment of the following critical parameters:

• Capacitance value: 470 µF (exact match required)
• Voltage rating: 400 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package type: Radial, Can - Snap-In (exact match required)
• Mounting type: Through Hole (exact match required)
• Lead spacing: 0.394" (10.00 mm) (exact match required)
• Physical dimensions: 1.378" Dia (35.00 mm) and compatible height (max 1.858")
• Operating temperature range: -40°C ~ 85°C (exact match required)
• Polarization: Polar (exact match required)

The B43501A9477M002 qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. Variations in ESR, ripple current, impedance, and height within tolerance do not preclude substitution when all primary parameters align.
