    Hi
    I have a query regarding resistor dynamics. I am cloning an open source circuit (OpenBCI Cyton board) but for some reason mouser decided to not ship 14 resistors of single model.
    The original component's mfg no is MCS04020C1001FE000. It is a thin film SMD has a 1/16 Watt and 50 Volt rating with 0402 packaging.

    1. Can it be replaced by a 1/4 Watt 200 volt resistor? Do Voltage and wattage play an important role in determining the behavior of resistor in circuit?
    2. If I use 0805 or 1206 packaging then can the resistor short circuit (touch different paths) or cause issues?

    Thanks in advance!!

    1. As long as the size fits (0402) and the power rating (voltage, wattage) is higher than the originally requested one a replacement is fine. Otoh 0402 with 1/4 W and 200 V? I doubt this exists.
    2. Impossible to say without knowing the layout. There may or may not be parts near that pose a risk of short circuit.

    Mouser offers more than 20 different types of 1 kΩ 0402 resistors. you can use any of them, not only the originally requested NCS series.

    Thanks for the advice Harald. I will try to get some appropriate resistors locally. Mouser is not an option anymore as shipping takes a lott of time!
