It can be done if absolutely necessary, but usually the circuit will not function properly unless totally redesigned to compensate for the differences between the components. This is rarely worth the trouble unless a germanium substitute is not available and the circuit MUST be repaired at any cost.
So unless you know exactly what you are doing and how to design transistor circuitry from scratch (after reverse engineering the old circuit), consider such substitutions to be impossible.
because1) knee voltage of silicon is .7V where as germanium has .3V 2)silicon breakdown take place at around 200 0C and germanium at 90 0C
yes.
What is the equivalent component to use in place sl100 transistor? ...
Elements in Group 14 on the Periodic Table have similar properties to carbon. These elements are carbon (C), silicon (Si), germanium (Ge), tin (Sn), lead (Pb), and flerovium (Fl). Each of these elements has two electrons in the outermost p orbital, the electron configuration ns2np2, and they tend to adopt oxidation sates of +4 (+2 for the heavier elements due to the inert pair effect). Silicon is most similar to carbon.

The answer will depend on what you wish to substitute in place of the inequality.
Ekasilicon is germanium['eka' is Sanskrit language for: 'first' place down under Si)Germanium was isolated in 1886, and provided the best confirmed prediction of Mendeleev's periodic table, which was built up before the discovery of Ge.(Professor Dmitri Mendeleev published the first Periodic Table of the Atomic Elements in 1869).When he proposed his periodic table, he noted some gaps in the table, and predicted that as-of-yet unknown elements existed with properties appropriate to fill those gaps.

Good that can be used in place of another good.
transistor size depends on its channel length, that is the length of the region in which a transistor act as an electron tube. the shorter the region, the lowest the resistance, the fastest the transistor, etc... so, it is always good to scale transistor size. problem is that you have to apply a 'good' electrical field in the channel, in order to drive a good 'ON' or 'OFF' state for your transistor. that's why it's not easy to scale their size.
You can substitute words which are synonyms. They can be used in place of each other.
