Hi! You can update your schematic with the correct and measured connector, connect the pins and when you're done, press the "Update PCB" button which will then delete the wrong connector and place the new connector in the PCB editor. You'll have to place it where it's supposed to be and connect the traces. And since the old one is bigger, I suppose you won't have to rearrange other parts. That is why there is a warning when using user contributed parts. Before ordering, please print the layout on a piece of paper and test it out. Do they fit? Paper is cheaper than PCB's and time. Here is a nice video by Robert Feranec about the paper PCB method: [https://www.youtube.com/watch?v=tPvSeOl5GWQ](https://www.youtube.com/watch?v=tPvSeOl5GWQ)<br> <br> Hope this helps and others please also check the PCB's on paper.

You can delete old one, and place a new one, set the prefix same as before, and then reset the component ID [https://docs.easyeda.com/en/Schematic/Reset-Component-ID/index.html](https://docs.easyeda.com/en/Schematic/Reset-Component-ID/index.html)

@UserSupport, Surely it is easier and less prone to errors to do what deskpro256 described? If the OP just replaces the Footprint, resets the prefix and the component ID in the PCB without making the same changes to the Symbol in the Schematic, the next time Update PCB... or Import Changes... is carried out, the Footprint attribute of the Schematic Symbol will overwrite the changes made to the Footprint in the PCB causing it to revert to the original.

Yes,you are right If only want to replace footprint, just need update part footprint at schematic Footprint Manager at Tools menu @andyfierman

@jared77441, All Symbols and Footprints especially those that are User Contributed should be checked for symbol pin, footprint pad and dimensional correctness against the original manufacturer's datasheets. If you already have part to hand then as deskpro256 says you can do this as a printed paper exercise or you can refer to the datasheets and check them in the Symbol and Footprint Editors in EasyEDA. There are several tools and tricks that you can use in the Footprint Editor to accurately check dimensions such as temporarily changing the measurement Units, the Grid spacing and the Origin as well as using the PCB Tools > Dimension tool  (N hotkey) and the Edit > Measure (M hotkey). There are also checklists (4) and (6) in (2) in : [https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a](https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a)<br> <br> that are to help avoid mistakes.

Thanks Much for the comments

@UserSupport, Thanks.

@jared77441, You are welcome.
