Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECW-FD2W564KC is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 0.56 µF (exact match required)
• Tolerance: ±10% (exact match required)
• DC voltage rating: 450V (exact match required)
• Dielectric material: Polypropylene (PP), Metallized (exact match required)

Mechanical Parameters:

• Mounting type: Through Hole (exact match required)
• Package type: Radial (exact match required)
• Physical dimensions: 0.689" L x 0.244" W / 17.50mm x 6.20mm (exact match required)
• Height seated: 0.370" / 9.40mm (exact match required)
• Lead spacing: 0.591" / 15.00mm (exact match required)
• Termination: PC Pins (exact match required)

Environmental & Compliance Parameters:

• Operating temperature range: -40°C ~ 110°C (exact match required)
• RoHS3 Compliance (required)
• REACH Unaffected status (required)

The ECW-FD2W564K qualifies as a parametric equivalent based on full alignment with all critical electrical, mechanical, and compliance parameters. The AC voltage rating specification present in the substitute part does not affect DC-primary application compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (ECW-FD2W564KC): The ECW-FD2W564KC is the specified component for applications requiring the exact part number designation. This part maintains Active product status with established supply availability. ROHS3 compliance and REACH Unaffected status confirm regulatory alignment for industrial and commercial applications.

Substitute Part Selection (ECW-FD2W564K): The ECW-FD2W564K is a direct parametric equivalent suitable for applications where the primary part is unavailable or where extended lead times present supply chain constraints. This substitute maintains identical electrical performance, mechanical compatibility, and regulatory compliance. The substitute part demonstrates higher current inventory levels (1906 units versus 990 units), providing improved availability for time-sensitive procurement scenarios. Both parts are manufactured by Panasonic Electronic Components within the ECW-F(D) series and are classified as Active products.

Compliance Verification: Both parts satisfy ROHS3 Compliance and REACH Unaffected requirements. Selection between the primary and substitute part does not introduce regulatory compliance risk for applications within the specified operating temperature range (-40°C ~ 110°C) and voltage specifications (450V DC).

Frequently Asked Questions (FAQ)

Q: Can ECW-FD2W564K be used as a direct replacement for ECW-FD2W564KC?

A: Yes. The ECW-FD2W564K is a parametric equivalent with identical capacitance (0.56 µF), tolerance (±10%), DC voltage rating (450V), dielectric material (polypropylene metallized), physical dimensions, lead spacing, and operating temperature range. Both parts are through-hole radial components with PC pin termination and identical mechanical footprints.

Q: What is the difference between ECW-FD2W564KC and ECW-FD2W564K?

A: The primary difference is the AC voltage rating specification. The ECW-FD2W564K includes an AC voltage rating of 84V, while the ECW-FD2W564KC does not specify an AC rating. For DC-primary applications, this difference does not affect functional compatibility. Both parts share identical DC voltage ratings (450V) and all mechanical parameters.

Q: Are there any PCB layout considerations when substituting these parts?

A: No. Both parts maintain identical physical dimensions (0.689" L x 0.244" W), height (0.370"), and lead spacing (0.591" / 15.00mm). PCB footprints, mounting holes, and component spacing remain unchanged between the primary and substitute part.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both ECW-FD2W564KC and ECW-FD2W564K are ROHS3 Compliant and REACH Unaffected. Regulatory compliance is maintained across both parts for applications requiring these certifications.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should be based on current inventory availability, supplier lead times, and procurement preferences. Both parts are Active products manufactured by Panasonic Electronic Components and provide equivalent electrical and mechanical performance.

Q: Are these parts suitable for high-frequency and switching applications?

A: Yes. Both parts are specified for EMI/RFI suppression, high-frequency switching, and high pulse/DV/DT applications. The polypropylene metallized dielectric construction supports these application requirements across the full operating temperature range (-40°C ~ 110°C).
