Leiditech SR05-02A can replace Germany WE 824011 Germany WE P/N 824011, Features as below: Package: SOT-23-5L Voltage: 5v Low Capacitance; 2PF@ IPP: 12A (8/20us) Internal Diagram: Package size picture: Leiditech P/N SR05-02A ,features as below: Package: SOT-143 Voltage: 5v Capacitance:2pf IPP:12A (8/20us) Internal diagram: Package size diagram: Analysis Leiditech SR05-02A and WE 824011, we can find: 1.Internal diagrams are the same, know the chips are the same. 2. The electrical properties both are 5v, 2pf, 12A (8/20us) 3. The packages are different: WE 824011 is SOT-23-5L, Leiditech SR05-02A is SOT-143. Analysis SOT-23-5L and SR05-02A,we can fine same pints, as below: 1. SOT-23-5L: the width between 4th pin and 15th is 1.9mm SOT-143: the width between 3rd pin and 4th is 1.9mm 2. SOT-23-5L: the width between 2nd pin and the 3rd pin is 0.95, the width between 2nd pin and 2nd pin is 0.95 SOT-143: the width of 1st pin is 0.95,the width between 1th and 2nd pin is 1.92.the width is 0.95 for 1st itself, so it can across and replace SOT-23-5L 1st and 2nd pins. 3. SOT-23-5L’s width for the plastic itself is 1.6mm SOT-143’s width for the plastic itself is 1.3mm Can make up the width for the pins Conclusion: SOT-23-5L and SR05-02A can replaced by each other without change the PCB ,Leiditech SR05-02A can replace Germany WE 824011
