Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECW-FD2W225KC is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 2.2 µF (exact match required)
• Tolerance: ±10% (exact match required)
• DC voltage rating: 450V (minimum requirement; higher ratings acceptable)
• Dielectric material: Polypropylene (PP), Metallized (exact match required)
• Operating temperature range: -40°C ~ 110°C (minimum requirement)

Mechanical Parameters:

• Mounting type: Through Hole (exact match required)
• Package configuration: Radial (exact match required)
• Lead spacing: 0.591" / 15.00mm (exact match required)
• Height seated maximum: 0.563" / 14.30mm (exact match required)
• Termination: PC Pins (exact match required)

Compliance Parameters:

• RoHS3 Compliant status (required)
• Product Status: Active (required)

The ECW-FD2W225K qualifies as a parametric equivalent based on matching all electrical, mechanical, and compliance criteria. The presence of AC voltage rating specification in the substitute part does not alter DC circuit compatibility when all other parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the ECW-FD2W225KC and ECW-FD2W225K maintain Active product status with full RoHS3 compliance and REACH unaffected designation, ensuring regulatory compliance for current and future applications. Selection between these parts is based on inventory availability and procurement lead time considerations, as electrical and mechanical parameters are equivalent.

The ECW-FD2W225KC is suitable for applications where current stock availability is prioritized. The ECW-FD2W225K provides an alternative with significantly higher inventory levels (56,059 pieces versus 760 pieces), enabling expedited procurement for high-volume production requirements or time-sensitive applications.

Both parts are constructed from identical dielectric material (polypropylene metallized) and operate within the same temperature range (-40°C ~ 110°C), ensuring consistent performance in EMI/RFI suppression, high-frequency switching, and high pulse applications. The radial through-hole configuration with PC pin termination and 15.00mm lead spacing ensures direct mechanical and electrical compatibility with existing PCB layouts designed for either part number.

Frequently Asked Questions (FAQ)

Q: Can ECW-FD2W225K be used as a direct replacement for ECW-FD2W225KC in existing circuit designs?

A: Yes. The ECW-FD2W225K is electrically and mechanically equivalent to the ECW-FD2W225KC. Both parts share identical capacitance (2.2 µF), tolerance (±10%), DC voltage rating (450V), dielectric material (polypropylene metallized), operating temperature range (-40°C ~ 110°C), and physical dimensions. The radial through-hole configuration with 15.00mm lead spacing and PC pin termination ensures direct PCB compatibility without layout modifications.

Q: What is the significance of the AC voltage rating specification in the ECW-FD2W225K?

A: The ECW-FD2W225K includes an AC voltage rating of 84V in its specification, whereas the ECW-FD2W225KC does not specify an AC rating. This additional specification does not affect DC circuit operation. Both parts are rated for 450V DC operation and are suitable for applications requiring DC voltage suppression, EMI/RFI filtering, and high-pulse performance.

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

A: No. Both the ECW-FD2W225KC and ECW-FD2W225K are ROHS3 compliant and REACH unaffected. Both maintain Active product status and are suitable for applications requiring current regulatory compliance standards.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by equivalence across capacitance value (2.2 µF), tolerance (±10%), DC voltage rating (450V), dielectric material (polypropylene metallized), operating temperature range (-40°C ~ 110°C), mounting type (through hole), package configuration (radial), lead spacing (15.00mm), physical dimensions, and termination type (PC pins). All parameters must match exactly for direct substitution.

Q: Which part should be selected for high-volume production?

A: The ECW-FD2W225K is recommended for high-volume production due to significantly higher inventory availability (56,059 pieces compared to 760 pieces for the ECW-FD2W225KC). This inventory level enables expedited procurement and reduces lead time risk for large-scale manufacturing operations.

Q: Are these parts suitable for both AC and DC applications?

A: These parts are primarily specified for DC applications with 450V DC rating. The ECW-FD2W225K includes an additional AC voltage rating of 84V. For applications requiring AC voltage operation, the ECW-FD2W225K specification should be referenced. Both parts are suitable for EMI/RFI suppression, high-frequency switching, and high-pulse applications where DC voltage transient control is required.
