Substitute Part Grouping Explanation
Substitute components within the linear amplifier category are grouped strictly based on the following allowed parameters: amplifier type (general purpose), number of circuits (4), electrical parameters (slew rate, gain bandwidth, input bias current, input offset voltage, supply and output currents, and supply voltage range), packaging (surface mount), and compliance status. Only those parts which match or exceed these defined values, and have the same or compatible package outlines, are considered valid substitutes.
