Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the QAP2G684JRP must satisfy the following critical parameters to ensure functional equivalence:

• Capacitance Value: 0.68 µF (exact match required)
• Voltage Rating: 400V DC minimum
• Tolerance: ±5% or tighter
• Dielectric Type: Polypropylene (PP), Metallized
• Mounting Configuration: Through-hole axial
• Termination Style: PC Pins
• Operating Temperature: -40°C to 85°C minimum range

The MPF1403680JJ from Nichicon meets these substitution criteria as a film capacitor with matching electrical specifications and through-hole axial packaging.

Parameter Comparison

Engineering Selection Recommendations

The MPF1403680JJ is classified as an active product, providing supply continuity advantages over the obsolete QAP2G684JRP. Both components share identical ECCN and HTSUS classifications, indicating equivalent regulatory treatment. The substitute maintains the same manufacturer source (Nichicon), reducing qualification complexity for system integrators.

Selection of the MPF1403680JJ should be based on confirmation that the complete electrical and mechanical specifications align with circuit requirements, particularly voltage rating, tolerance, and physical dimensions for PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can the MPF1403680JJ be used as a direct replacement for QAP2G684JRP?

A: The MPF1403680JJ is a film capacitor from Nichicon with matching 0.68 µF capacitance. Compatibility depends on verification that voltage rating, tolerance, dielectric type, and axial through-hole configuration meet circuit specifications. Complete datasheet review is required before implementation.

Q: What are the critical parameters for substitution?

A: Capacitance value (0.68 µF), DC voltage rating (400V minimum), tolerance (±5%), dielectric material (polypropylene metallized), mounting type (through-hole axial), and operating temperature range (-40°C to 85°C) must all be matched or exceeded.

Q: Why is the QAP2G684JRP listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The MPF1403680JJ, classified as active, represents the current production alternative from the same manufacturer.

Q: Are there physical dimension considerations for PCB replacement?

A: The QAP2G684JRP dimensions are 18.70mm W, 10.50mm T x 30.00mm L. Physical dimensions of the substitute must be verified against available PCB footprint space and lead spacing requirements.

Q: Do both parts share the same regulatory compliance?

A: Both components carry EAR99 ECCN classification and 8532.25.0060 HTSUS code, indicating equivalent export and tariff treatment.
