ECW-FD2J564KC Film Capacitor Equivalent & Substitute Parts

Part Overview

The ECW-FD2J564KC 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 1044 units in stock and maintains ROHS3 compliance and REACH unaffected status. Equivalent substitute parts may be required due to inventory constraints, regional availability, or procurement lead time considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECW-FD2J564KC is determined by strict equivalence across the following critical parameters:

• Capacitance value: 0.56 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating - DC: 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 / Case: Radial (exact match required)
• Physical dimensions and lead spacing (exact match required for PCB compatibility)
• Termination type: PC Pins (exact match required)

The ECW-FD2J564K qualifies as a parametric equivalent substitute based on matching all critical electrical and mechanical parameters. The presence of AC voltage rating (141V) in the substitute part does not disqualify it, as this parameter is not specified in the main part and does not conflict with DC-only operation requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the ECW-FD2J564KC and ECW-FD2J564K are active production parts from Panasonic Electronic Components with identical compliance certifications (ROHS3 Compliant, REACH Unaffected). Selection between these parts should be based on:

• Inventory availability and procurement lead times
• Regional supplier stock levels
• Cost considerations where applicable
• Existing supply chain relationships

Both parts meet all regulatory and environmental compliance requirements for deployment in equivalent applications. The ECW-FD2J564K carries an additional AC voltage rating specification (141V) not present in the main part specification, which does not impact DC-only circuit applications.

Frequently Asked Questions (FAQ)

Q: Can ECW-FD2J564K be used as a direct replacement for ECW-FD2J564KC?

A: Yes. Both parts share identical electrical specifications (0.56 µF, ±10%, 630V DC), dielectric material (polypropylene metallized), operating temperature range (-40°C ~ 105°C), and mechanical dimensions (0.701" L x 0.331" W, 15.00mm lead spacing). Both are radial through-hole components with PC pin termination and identical series designation (ECW-F(D)).

Q: Are there any physical compatibility concerns when substituting these parts?

A: No. The parts are mechanically identical with matching dimensions, lead spacing, and mounting type. PCB layout and footprint requirements remain unchanged.

Q: Do both parts meet the same compliance standards?

A: Yes. Both ECW-FD2J564KC and ECW-FD2J564K are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements.

Q: What is the significance of the AC voltage rating on the ECW-FD2J564K?

A: The ECW-FD2J564K includes an AC voltage rating specification (141V) that is not listed for the ECW-FD2J564KC. This additional specification does not restrict DC-only applications and does not affect substitution eligibility for circuits operating at 630V DC.

Q: Are both parts currently in production?

A: Yes. Both parts maintain active product status with Panasonic Electronic Components. Current inventory levels are 1044 units (ECW-FD2J564KC) and 1013 units (ECW-FD2J564K).
