Key Parameters

Substitute Part Grouping Explanation

Substitution of the QAP2J225KRP is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 2.2 µF (exact match required)
• Voltage Rating: 630V DC minimum (equal or higher acceptable)
• Tolerance: ±10% (equal or tighter acceptable)
• Dielectric Type: Polypropylene (PP), Metallized (required for application compatibility)
• Mounting Configuration: Through-hole axial package (physical and electrical interface requirement)
• Operating Temperature: -40°C ~ 85°C minimum range (application environment compatibility)
• Termination Style: PC Pins (PCB interface compatibility)

The MPF1634220KN from Nichicon meets all substitution criteria as an active-status alternative to the obsolete QAP2J225KRP.

Engineering Selection Recommendations

The MPF1634220KN is the recommended substitute for the obsolete QAP2J225KRP based on the following engineering criteria:

Product Status: The QAP2J225KRP is obsolete, while the MPF1634220KN maintains active manufacturing status, ensuring long-term availability and supply chain continuity.

Electrical Equivalence: Both components share identical capacitance (2.2 µF), voltage rating (630V DC), tolerance (±10%), and dielectric composition (polypropylene metallized film), ensuring direct functional replacement in high-frequency and switching applications.

Regulatory Compliance: Both parts carry identical ECCN (EAR99) and HTSUS (8532.25.0060) classifications, maintaining compliance with export and tariff requirements. The main part's ROHS3 compliance is preserved through the substitute's film capacitor construction.

Physical Interface: Axial through-hole mounting with PC pin termination is maintained, allowing direct PCB integration without layout or assembly modifications.

Thermal Performance: Operating temperature range of -40°C ~ 85°C is supported by the substitute, meeting application environmental requirements.

Frequently Asked Questions (FAQ)

Q: Can the MPF1634220KN be used as a direct replacement for the QAP2J225KRP without PCB modifications?

A: Yes. Both components are axial through-hole packages with identical pin spacing and termination style (PC Pins). No PCB layout changes are required for substitution.

Q: Are there any electrical performance differences between these two capacitors?

A: No. Both components share identical electrical specifications: 2.2 µF capacitance, 630V DC rating, ±10% tolerance, and polypropylene metallized dielectric construction. They are electrically equivalent for all specified applications.

Q: Why is the QAP2J225KRP classified as obsolete?

A: Obsolescence typically reflects manufacturer discontinuation of a product line. The MPF1634220KN represents Nichicon's current active offering for this capacitance and voltage class, ensuring ongoing availability and manufacturing support.

Q: What is the significance of the ROHS3 compliance marking on the main part?

A: ROHS3 compliance indicates the component meets Restriction of Hazardous Substances Directive requirements, restricting lead and other hazardous materials. The substitute's film capacitor construction maintains this compliance standard.

Q: Are there inventory considerations when transitioning from QAP2J225KRP to MPF1634220KN?

A: The QAP2J225KRP has 1,075 units in stock (new original), while the MPF1634220KN has 694 units available. Both represent adequate inventory for component procurement decisions.

Q: Do both parts carry the same export classification?

A: Yes. Both components are classified as EAR99 under export control regulations and share the identical HTSUS tariff code (8532.25.0060), ensuring consistent regulatory treatment in procurement and logistics.
