Substitute Part Grouping Explanation

Substitution of the QAP2G684KRP is determined by strict equivalence across the following critical parameters:

• Capacitance value: 0.68 µF
• Tolerance: ±10%
• Voltage rating: 400V DC minimum
• Dielectric type: Polypropylene (PP), Metallized
• Mounting configuration: Through-hole axial
• Termination style: PC pins
• Operating temperature range: -40°C to 85°C minimum

The Nichicon MPF1403680KJ meets all specified electrical and mechanical requirements for direct substitution. Both parts share identical capacitance, voltage rating, dielectric composition, and package configuration, ensuring functional compatibility in the target application.

Parameter Comparison

Engineering Selection Recommendations
