Substitute Part Grouping Explanation

Substitution eligibility for the ECW-FD2W474KC is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 0.47 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating - DC: 450V (exact match required)
• Dielectric Material: Polypropylene (PP), Metallized (exact match required)
• Operating Temperature Range: -40°C ~ 110°C (exact match required)

Mechanical Parameters:

• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Size / Dimension: 0.689" L x 0.228" W / 17.50mm x 5.80mm (exact match required)
• Height - Seated (Max): 0.354" / 9.00mm (exact match required)
• Lead Spacing: 0.591" / 15.00mm (exact match required)
• Termination: PC Pins (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)
• Manufacturer: Panasonic Electronic Components (same manufacturer preferred)
• Series: ECW-F(D) (same series preferred)

The substitute part ECW-FD2W474K meets all electrical and mechanical equivalence criteria, with the addition of an AC voltage rating specification (84V AC) not present in the main part specification.

Parameter Comparison

Engineering Selection Recommendations

Both the ECW-FD2W474KC and ECW-FD2W474K are Active products manufactured by Panasonic Electronic Components within the ECW-F(D) series. Both parts maintain ROHS3 compliance and REACH unaffected certification status, meeting current regulatory requirements for electronic component deployment.

The ECW-FD2W474K substitute part demonstrates complete electrical and mechanical equivalence to the main part across all specified parameters. The addition of an AC voltage rating (84V) in the substitute part specification does not diminish its suitability for DC-rated applications and represents an expanded operational envelope.

Selection between these parts is based on availability and inventory status. The ECW-FD2W474K maintains significantly higher inventory levels (108,721 pcs) compared to the ECW-FD2W474KC (2,021 pcs), making it the preferred choice for procurement when supply chain continuity is a consideration.

Frequently Asked Questions (FAQ)

Q: Can ECW-FD2W474K be used as a direct replacement for ECW-FD2W474KC?

A: Yes. The ECW-FD2W474K meets all electrical and mechanical equivalence criteria for the ECW-FD2W474KC. Both parts share identical capacitance (0.47 µF), tolerance (±10%), DC voltage rating (450V), dielectric material (polypropylene metallized), operating temperature range (-40°C ~ 110°C), and physical dimensions (0.689" L x 0.228" W, 15.00mm lead spacing). Direct substitution is supported without circuit modification.

Q: What determines whether a part qualifies as a substitute for ECW-FD2W474KC?

A: Substitution eligibility requires exact equivalence across capacitance value, tolerance, DC voltage rating, dielectric material type, operating temperature range, mounting type (through hole), package style (radial), physical dimensions, lead spacing, termination type (PC pins), and RoHS compliance status. All parameters must match the original specification.

Q: Does the AC voltage rating on ECW-FD2W474K affect its use in DC applications?

A: No. The AC voltage rating (84V) specified on ECW-FD2W474K is an additional parameter that does not affect DC circuit performance. The part maintains the same 450V DC rating as the main part and operates identically in DC-rated applications.

Q: Are both parts suitable for EMI/RFI suppression applications?

A: Yes. Both ECW-FD2W474KC and ECW-FD2W474K are specified for EMI/RFI suppression, high-frequency switching, and high pulse/DV/DT applications. Application suitability is identical between the two parts.

Q: What is the physical footprint compatibility between these parts?

A: Both parts are identical in physical footprint. The radial package dimensions (0.689" L x 0.228" W / 17.50mm x 5.80mm), seated height (0.354" / 9.00mm), and lead spacing (0.591" / 15.00mm) are equivalent, ensuring PCB layout compatibility without modification.

Q: Do both parts meet current regulatory compliance requirements?

A: Yes. Both ECW-FD2W474KC and ECW-FD2W474K maintain ROHS3 compliance and REACH unaffected certification status, meeting current regulatory requirements for electronic component deployment in regulated markets.
