I don't understand your question.
Do you know what the things that you posted are?
The first one:
? ?"R6=2.42E-03 C6=1.21E-03 R5=2.95E-02? C5=6.20E-05 R4=2.03E-01? C4=2.69E-03 R3=2.34E-01? C3=3.21E-02 R2=5.94E-02? C2=1.81E-01 R1=2.47E-03? C1=8.25E-08"
is a list of resistor and capacitor values.? But there is nothing to show how they are connected.? Where did you get that from?
The second one:
? ?"CTHERM1 TH 6 7.5e-3 ? ?? ? CTHERM2 6 5 8.0e-3? ? ?? CTHERM3 5 4 9.0e-3? ? ?? CTHERM4 4 3 2.4e-2? ? ?? CTHERM5 3 2 3.4e-2? ? ?? CTHERM6 2 TL 6.5e-2? ? ?? RTHERM1 TH 6 3.1e-4? ? ?? RTHERM2 6 5 2.5e-3? ? ?? RTHERM3 5 4 2.2e-2? ?? ? RTHERM4 4 3 8.1e-2? ? ?? RTHERM5 3 2 1.35e-1? ? RTHERM6 2 TL 1.5e-1"
is a SPICE subcircuit.? It has both the values (e.g., 7.5e-3) and how they are interconnected.
Both methods use a SPICE circuit to represent the thermal characteristics of something.? How it gets used, well that depends on what the other devices are in your SPICE circuit.
If you want to understand the differences between the two methods, you could look at the step response of each circuit.? They might be similar, even if the values of the R's and C's within them, are not the same.
I can't answer your question because there is no clear question.
