Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the QAP2E684KRP are determined by strict equivalence across the following critical parameters:

• Capacitance Value: 0.68 µF (exact match required)
• Tolerance: ±10% (acceptable range for electrical performance)
• Voltage Rating: 250V DC (minimum requirement for circuit safety and reliability)
• Dielectric Material: Polypropylene (PP), Metallized (determines frequency response and application suitability)
• Mounting Type: Through Hole (physical board compatibility)
• Package Configuration: Axial (footprint and lead spacing compatibility)
• Operating Temperature: -40°C ~ 85°C (thermal performance envelope)

Substitute parts must maintain compliance with RoHS3 and REACH requirements to ensure regulatory alignment with the original component.

Parameter Comparison

Engineering Selection Recommendations

The MPF1253680KG is a direct substitute for the QAP2E684KRP based on electrical and mechanical parameter equivalence. Both components are manufactured by Nichicon and share identical capacitance, tolerance, voltage rating, dielectric material type, mounting configuration, and package format.

The primary advantage of selecting the MPF1253680KG is its active product status, which ensures ongoing availability and supply chain continuity compared to the obsolete QAP2E684KRP. Both components maintain compliance with EAR99 export classification and HTSUS tariff code 8532.25.0060, supporting consistent regulatory and procurement workflows.

The substitute part is suitable for direct replacement in applications requiring 0.68 µF, 250V DC film capacitors in axial through-hole configurations, particularly in high-frequency and switching circuit designs operating within the -40°C to 85°C temperature range.

Frequently Asked Questions (FAQ)

Q: Can the MPF1253680KG be used as a direct replacement for the QAP2E684KRP?

A: Yes. Both components share identical electrical specifications (0.68 µF, ±10%, 250V DC) and physical configuration (axial through-hole package). The MPF1253680KG is manufactured by the same supplier and is electrically and mechanically compatible.

Q: What is the primary reason to switch from QAP2E684KRP to MPF1253680KG?

A: The QAP2E684KRP is classified as obsolete, while the MPF1253680KG maintains active product status. This ensures reliable component availability for current and future production requirements.

Q: Are there any physical dimension differences between these parts?

A: Physical dimensions are not specified for the MPF1253680KG in the provided data. Verification of mechanical compatibility, including lead spacing and package dimensions, is necessary before board-level integration.

Q: Do both parts meet the same regulatory requirements?

A: Both components are classified under ECCN EAR99 and HTSUS code 8532.25.0060. The QAP2E684KRP is confirmed ROHS3 compliant. Regulatory compliance documentation for the MPF1253680KG should be obtained from the manufacturer to confirm equivalent status.

Q: Can these capacitors be used interchangeably in all circuit applications?

A: Substitution is valid for applications requiring 0.68 µF, 250V DC film capacitors in through-hole axial configurations. Circuit-specific performance requirements, such as frequency response, ESR, or temperature coefficient characteristics, should be evaluated against manufacturer datasheets if available.
