Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECW-FD2W824KC is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 0.82 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)
• Lead spacing: 0.591" / 15.00mm (exact match required)
• Termination style: PC Pins (exact match required)

Environmental & Compliance Parameters:

• Operating temperature range: -40°C ~ 110°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

The substitute part ECW-FD2W824K meets all critical electrical, mechanical, and compliance parameters. The addition of AC voltage rating (84V) in the substitute part does not disqualify substitution, as this parameter is supplementary to the primary DC rating specification.

Parameter Comparison

Engineering Selection Recommendations

Both the ECW-FD2W824KC and ECW-FD2W824K are Active products manufactured by Panasonic Electronic Components within the ECW-F(D) series. Selection between these parts is based on availability and supply chain requirements, as they are electrically and mechanically equivalent.

ECW-FD2W824KC is suitable for applications requiring the primary specification set with 1037 pieces currently in stock.

ECW-FD2W824K provides an equivalent alternative with 2281 pieces in stock, offering greater availability. This substitute part includes an AC voltage rating specification (84V) not present in the main part specification, which does not restrict its use in DC-primary applications.

Both parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment for industrial and commercial applications. Selection should be based on procurement lead time, inventory position, and supply chain logistics.

Frequently Asked Questions (FAQ)

Q: Can ECW-FD2W824K be used as a direct replacement for ECW-FD2W824KC?

A: Yes. The ECW-FD2W824K meets all critical electrical parameters (0.82 µF capacitance, ±10% tolerance, 450V DC rating), mechanical specifications (radial through-hole package, 15.00mm lead spacing), and environmental ratings (-40°C ~ 110°C operating range). Both parts are ROHS3 compliant and manufactured by Panasonic Electronic Components within the same ECW-F(D) series.

Q: What is the significance of the AC voltage rating in the substitute part?

A: The ECW-FD2W824K includes an AC voltage rating of 84V, which is supplementary information not specified in the ECW-FD2W824KC datasheet. This additional parameter does not affect substitution eligibility for DC-primary applications and may provide additional application flexibility.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts share identical dimensions: 0.689" L x 0.283" W (17.50mm x 7.20mm) body size, 0.409" (10.40mm) maximum seated height, and 0.591" (15.00mm) lead spacing. PCB layout and mechanical mounting are fully compatible.

Q: Do both parts support the same applications?

A: Yes. Both the ECW-FD2W824KC and ECW-FD2W824K are rated for EMI/RFI suppression, high-frequency switching, and high pulse/DV/DT applications with identical operating temperature ranges and dielectric materials.

Q: What is the difference in inventory availability?

A: The ECW-FD2W824KC has 1037 pieces in stock, while the ECW-FD2W824K has 2281 pieces available. The substitute part offers greater inventory depth for supply chain continuity.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH Unaffected, and classified under ECCN EAR99. Regulatory and environmental compliance status is identical.
