Figure 9: Typical configuration for a drop-in replacement
As shown in the red block above, Pin 1, 5, 11 and 15 are VDD pins in KT0803 that are
required to be connected to a decoupling capacitor. These four pins are GND pins in
KT0803K. Customers can replace the decoupling capacitor of a 0-ohm resister without
PCB board change.
