Substitute Part Grouping Explanation

Substitution of the MMP6P47K is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in capacitance value, voltage ratings, dielectric composition, temperature operating range, physical dimensions, and termination type to ensure direct compatibility in circuit applications without circuit redesign or board layout modification.

The following parameters establish substitution validity:

• Capacitance: 0.47 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating - DC: 630V (exact match required)
• Voltage Rating - AC: 250V (exact match required)
• Dielectric Material: Polyester, Metallized (exact match required)
• Operating Temperature: -55°C to 125°C (exact match required)
• Package Type: Axial (exact match required)
• Physical Dimensions: 17.50mm × 12.00mm × 35.00mm (exact match required)
• Termination: PC Pins (exact match required)
