ECW-FE2J474KA Film Capacitor Equivalent & Substitute Parts

Part Overview

The ECW-FE2J474KA is a 0.47 µF film capacitor manufactured by Panasonic Electronic Components, rated for 630V DC operation with polypropylene (PP) metallized dielectric construction. This radial through-hole component is designed for EMI/RFI suppression, high-frequency switching, and high pulse/DV/DT applications. The part maintains Active product status with full ROHS3 compliance and REACH unaffected certification. Substitute parts are identified when equivalent electrical and mechanical parameters align within the allowed specifications for this product category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECW-FE2J474KA is determined by strict alignment of the following critical parameters:

• Capacitance value: 0.47 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)
• Lead Spacing: 0.591" (15.00mm) (exact match required)
• Termination: PC Pins (exact match required)

The ECW-FE2J474K qualifies as a parametric equivalent based on matching all critical electrical and mechanical specifications. The presence of AC voltage rating (141V) in the substitute part does not disqualify it, as this parameter is supplementary to the primary DC rating specification.

Parameter Comparison

Engineering Selection Recommendations

Both the ECW-FE2J474KA and ECW-FE2J474K maintain Active product status with identical compliance certifications (ROHS3 Compliant, REACH Unaffected). Selection between these parts should be based on inventory availability and application-specific requirements. The ECW-FE2J474K currently maintains higher inventory levels (1412 Pcs vs. 804 Pcs), which may influence procurement decisions for high-volume applications. Both parts are suitable for EMI/RFI suppression, high-frequency switching, and high pulse/DV/DT applications within the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can ECW-FE2J474K be used as a direct replacement for ECW-FE2J474KA?

A: Yes. Both parts share identical capacitance (0.47 µF), tolerance (±10%), DC voltage rating (630V), dielectric material (Polypropylene metallized), operating temperature range (-40°C ~ 105°C), mounting type (Through Hole), package configuration (Radial), physical dimensions, lead spacing (15.00mm), and termination type (PC Pins). The parts are electrically and mechanically interchangeable.

Q: What is the significance of the AC voltage rating difference?

A: The ECW-FE2J474K includes an AC voltage rating specification (141V) while the ECW-FE2J474KA does not. This supplementary parameter does not affect DC circuit applications. Both parts are rated identically for 630V DC operation, which is the primary specification for this component category.

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

A: No. Both parts are identical in physical dimensions (17.50mm L x 10.00mm W), seated height (15.50mm maximum), lead spacing (15.00mm), and termination configuration (PC Pins). PCB layout and mounting requirements remain unchanged.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both ECW-FE2J474KA and ECW-FE2J474K are ROHS3 Compliant and REACH Unaffected, with identical ECCN (EAR99) and HTSUS (8532.25.0070) classifications.
