Substitute Part Grouping Explanation

Substitution for the ECW-FD2J824KC is determined by strict equivalence across the following critical parameters:

• Capacitance value: 0.82 µF
• Capacitance tolerance: ±10%
• DC voltage rating: 630V minimum
• Dielectric type: Polypropylene (PP), Metallized
• Operating temperature range: -40°C ~ 105°C
• Mounting configuration: Through Hole, Radial
• Physical dimensions: 0.701" L x 0.402" W (17.80mm x 10.20mm)
• Lead spacing: 0.591" (15.00mm)
• Termination style: PC Pins

The substitute part ECW-FD2J824K meets all these criteria and belongs to the same ECW-F(D) series from Panasonic Electronic Components. Both parts are ROHS3 compliant and share identical mechanical and electrical specifications within the allowed parameter tolerance.

Parameter Comparison

Engineering Selection Recommendations

Both ECW-FD2J824KC and ECW-FD2J824K are active production parts from Panasonic Electronic Components with full ROHS3 compliance and REACH unaffected status. The substitute part ECW-FD2J824K provides higher inventory availability (1828 units versus 778 units) while maintaining identical DC voltage rating, capacitance value, tolerance, dielectric material, physical dimensions, and thermal operating range. Both parts are suitable for EMI/RFI suppression, high-frequency switching, and high pulse applications. Selection between these parts should be based on procurement lead time, inventory requirements, and application-specific AC voltage considerations.

Frequently Asked Questions (FAQ)

Q: Can ECW-FD2J824K replace ECW-FD2J824KC in all applications?

A: Yes, for applications where AC voltage rating is not a critical specification. Both parts share identical DC voltage rating (630V), capacitance (0.82 µF), tolerance (±10%), dielectric material (Polypropylene metallized), operating temperature range (-40°C ~ 105°C), and physical dimensions. The substitute part specifies an AC voltage rating of 141V, while the main part does not specify AC voltage. If your application requires AC voltage operation, confirm that 141V AC is sufficient for your circuit requirements.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts have identical dimensions: 0.701" L x 0.402" W (17.80mm x 10.20mm), maximum seated height of 0.654" (16.60mm), and lead spacing of 0.591" (15.00mm). Both use radial through-hole mounting with PC pin termination, ensuring direct mechanical and electrical compatibility on PCBs designed for either part.

Q: What is the difference between ECW-FD2J824KC and ECW-FD2J824K?

A: The primary difference is the AC voltage rating specification. ECW-FD2J824K specifies 141V AC, while ECW-FD2J824KC does not specify an AC rating. All other electrical and mechanical parameters are identical. Both parts belong to the same ECW-F(D) series and are manufactured by Panasonic Electronic Components.

Q: Are both parts RoHS compliant?

A: Yes. Both ECW-FD2J824KC and ECW-FD2J824K are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: Which part should I select for new designs?

A: Selection should be based on application requirements and procurement strategy. ECW-FD2J824K offers higher inventory availability (1828 units in stock) compared to ECW-FD2J824KC (778 units in stock). If AC voltage operation is required, confirm that the 141V AC rating of ECW-FD2J824K meets your circuit specifications. Both parts are active production items suitable for long-term design implementation.
