Practical Tips for Non-Direct Replacement

Double-check pin numbering to avoid miswiring.

Adjust external PCB components to suit the replacement IC’s characteristics.

Match power supply voltage; if it differs, adjust accordingly.

Measure IC’s static working current post-replacement for normal values; significant differences may indicate self-oscillation.

Match input and output impedance to the original PCB circuit.

Maintain tidy external leads and avoid crossings to prevent high-frequency oscillation.
