Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECW-FD2J394JC is determined by strict equivalence across the following critical parameters: capacitance value (0.39 µF), tolerance (±5%), DC voltage rating (630V), dielectric material (polypropylene metallized), operating temperature range (-40°C ~ 105°C), mounting type (through hole), package configuration (radial), lead spacing (15.00mm), and termination style (PC pins). The ECW-FD2J394J qualifies as a parametric equivalent substitute based on matching all these core electrical and mechanical specifications. AC voltage rating presence does not disqualify substitution when DC ratings and all other parameters remain identical.
