Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ECW-FG70155KA are identified through parametric equivalence. The substitution logic is based on the following critical parameters that must match exactly:

• Capacitance Value: 1.5 µF (no tolerance variation)
• Voltage Rating: 700V DC (minimum requirement)
• Dielectric Type: Polypropylene (PP), Metallized
• Mounting Configuration: Through Hole, Radial package
• Physical Footprint: 31.50mm L x 10.50mm W with 27.50mm lead spacing
• Termination: PC Pins
• Operating Temperature Range: -40°C ~ 110°C
• Compliance Standards: AEC-Q200, ROHS3

Parts meeting all these parameters are classified as direct parametric equivalents and may be substituted without circuit redesign or board layout modification.
