Substitute Part Grouping Explanation

Substitution of the ECW-FE2W104PD is determined by strict equivalence across the following critical parameters:

• Capacitance value: 0.1 µF
• Tolerance specification: ±5%
• Voltage ratings: 450V DC / 84V AC
• Dielectric material: Polypropylene (PP), Metallized
• Operating temperature range: -40°C ~ 105°C
• Mounting configuration: Through Hole Radial
• Lead spacing: 0.591" (15.00mm)
• Termination type: PC Pins
• Compliance certifications: ROHS3 Compliant

The ECW-FE2W104P5 meets all these parameters and is classified as a parametric equivalent. Both parts belong to the ECWFE series and maintain identical electrical and mechanical specifications.
