Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ECW-FG2J225QA are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

Capacitance value of 2.2 µF with ±10% tolerance ensures functional equivalence in circuit operation. Voltage ratings of 630V DC and 141V AC must be maintained to preserve circuit safety margins and reliability. Dielectric material specification (Polypropylene, Metallized) determines frequency response and performance characteristics. Operating temperature range of -40°C ~ 110°C must be supported for automotive and high-temperature applications. Mounting configuration (Through Hole, Radial) and lead spacing of 0.886" (22.50mm) ensure mechanical compatibility with existing PCB layouts. AEC-Q200 automotive qualification and ROHS3 compliance must be retained for regulated applications.
