ECW-FD2J564JC Film Capacitor Equivalent & Substitute Parts

Part Overview

The ECW-FD2J564JC is a 0.56 µF film capacitor manufactured by Panasonic Electronic Components, rated for 630V DC operation with polypropylene (PP) metallized dielectric. This radial through-hole component is designed for EMI/RFI suppression, high-frequency switching, and high pulse/DV/DT applications. The part is currently active in production with 1165 units in stock and maintains ROHS3 compliance and REACH unaffected status. Identifying equivalent and substitute parts is necessary for supply chain continuity, inventory optimization, and design flexibility across manufacturing environments.

Substitute Part Grouping Explanation

Substitution eligibility for the ECW-FD2J564JC is determined by strict equivalence across the following critical parameters:

• Capacitance value: 0.56 µF (exact match required)
• Tolerance: ±5% (exact match required)
• DC voltage rating: 630V (exact match required)
• Dielectric material: Polypropylene (PP), Metallized (exact match required)
• Operating temperature range: -40°C ~ 105°C (exact match required)
• Mounting type: Through Hole (exact match required)
• Package configuration: Radial (exact match required)
• Physical dimensions and lead spacing: 0.701" L x 0.331" W, 0.591" lead spacing (exact match required)
• Termination type: PC Pins (exact match required)

The substitute part ECW-FD2J564J meets all these criteria and is therefore classified as a parametric equivalent. The addition of AC voltage rating specification (141V) in the substitute part does not disqualify it from equivalence, as this parameter is supplementary to the primary DC rating and does not alter the core electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the ECW-FD2J564JC and ECW-FD2J564J are active production parts from Panasonic Electronic Components within the ECW-F(D) series. Both maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing standards. The substitute part ECW-FD2J564J is electrically and mechanically interchangeable with the main part across all specified parameters. Selection between these parts may be based on inventory availability, lead time, or supply chain logistics, as both deliver identical functional performance in applications requiring 0.56 µF, 630V DC film capacitor functionality.

Frequently Asked Questions (FAQ)

Q: Can ECW-FD2J564J be used as a direct replacement for ECW-FD2J564JC?

A: Yes. Both parts are parametric equivalents sharing identical capacitance (0.56 µF), tolerance (±5%), DC voltage rating (630V), dielectric material (polypropylene metallized), operating temperature range (-40°C ~ 105°C), mounting type (through hole), package configuration (radial), physical dimensions (0.701" L x 0.331" W), lead spacing (0.591"), and termination type (PC pins). No circuit modifications or PCB layout changes are required.

Q: What is the significance of the AC voltage rating difference?

A: The ECW-FD2J564J includes an AC voltage rating specification of 141V, while the ECW-FD2J564JC does not specify an AC rating. This supplementary parameter does not affect DC circuit compatibility or performance. Both parts are rated identically for DC operation at 630V, which is the primary design criterion for most industrial and switching applications.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts maintain identical RoHS3 compliance and REACH unaffected status. Both are manufactured by Panasonic Electronic Components and belong to the same ECW-F(D) series with matching base product number ECW-FD.

Q: What applications are these capacitors suitable for?

A: Both parts are specified for EMI/RFI suppression, high-frequency switching, and high pulse/DV/DT applications. The 630V DC rating and polypropylene metallized dielectric make these components suitable for power conditioning, filtering, and transient suppression in industrial control systems, switching power supplies, and high-voltage DC circuits.

Q: Are the physical dimensions identical for PCB mounting?

A: Yes. Both parts share identical dimensions (0.701" L x 0.331" W / 17.80mm x 8.40mm), maximum seated height (0.583" / 14.80mm), and lead spacing (0.591" / 15.00mm). PCB footprints and mounting holes require no modification when substituting between these parts.
