Resistor placement in a circuit. Are these examples OK?

    I have a circuit that I am trying to build again but in a surface mount configuration. I have a section or two that I need to jump to get this to work the way it is laid out. I saw the way resistors were laid out on this pre-biased transistor and it made me think.

    Part of the circuit is shown in the diagram below as Figure A. This is correct and working the way it is.

    {Look at R3 - these are the only changes between figure A,B,C and D}

    I would like to know if the figures B, C and D are acceptable also? It was not until I saw the data sheet above that raised these questions. This would solve a minor problem if and only if this is a correct way to accomplish what is in Figure A. I will try this again with the pre-biased transistors but this question is two basic in nature to ignore and not learn from.


    Thanks for and wisdom and feedback!

    They are the same thing....unless very high frequencies are involved.
    For switching below GHz. No problem
