Substitute Part Grouping Explanation

Substitution eligibility for the ECW-FE2W474PA is determined by strict equivalence across the following critical parameters:

• Capacitance value: 0.47 µF
• Tolerance specification: ±5%
• Voltage rating: 450V DC
• Dielectric type: Polypropylene (PP), Metallized
• Operating temperature range: -40°C ~ 105°C
• Mounting configuration: Through Hole, Radial
• Lead spacing: 0.394" (10.00mm)
• Physical dimensions: 0.512" L x 0.276" W (13.00mm x 7.00mm)
• Termination type: PC Pins

The ECW-FE2W474P1 meets all specified parameters and belongs to the same ECWFE series, qualifying as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the ECW-FE2W474PA and ECW-FE2W474P1 are active production components manufactured by Panasonic Electronic Components within the ECWFE series. Both parts maintain identical electrical specifications, mechanical dimensions, and compliance certifications (ROHS3 Compliant, REACH Unaffected). Selection between these parts may be based on inventory availability and procurement lead times, as they are functionally interchangeable for all specified applications including EMI/RFI suppression, high-frequency switching, and high pulse/DV/DT circuits.
