Analysis of two materials shows that:

The internal structure is the same, indicating that the chip structure is the same.

The chip electrical properties are all 5V, 2PF and 12A(8/20us).

The external package is different. One is SOT-23-5L and the other is SOT-143.

Find common ground in different package sizes:

The width of pins 4 and 5 of SOT-23-5L is 1.9 mm.

The width of the 3-pin and 4-pin of SOT-143 is 1.9 mm.

The width of the 2-pin and 3-pin of SOT-23-5L is 0.95, and that of the 1-pin and 2-pin is 0.95.

The width of the first leg of SOT-143 is 0.95, and the width of the first leg and the second leg is 1.92, because the width of the first leg itself is 0.95, which can span the width of the first leg and the second leg instead of SOT-23-5L.

The plastic width of SOT-23-5L is 1.6 mm.

The plastic width of SOT-143 is 1.3MM

Make up the width between pins.

Conclusion: The two packages can completely replace each other on the circuit board. No revision is needed.

Summary: Leiditech brand model SR05-02A can replace German WE brand model 824011.
