    Hi, I am attempting to build a small circuit for automotive testing for an engine swap I am working on, and I need a little help.

    I need a comparator and I was told I need a lm311n and I ordered a lm311p not realizing they may or may not be different.

    Here is what I want to make. http://www.autospeed.com/cms/article.html?&A=1716

    Will using the lm311p be okay?

    Hi there
    Welcome to the forums :)

    you shouldn't find any difference between the 2 different suffix letters
    it usually refers to a style of packaging ... plastic, ceramic, metal etc

    cheers
    Dave
