Searching for Transistor chips

Hello Guys.

I was able to change my CPU on this board but one stupid thing was happen:

I cant lift up the CPU with my mini Vakuum Sucker.

So there fell apart some pieces and now i need to replace the (TSP)51619 which controlls the Power of the DDR3L Memory. but byside of this are some tiny black

"Transistors"?

And there is no Water on the Board. it is only Pattex Glue to save the other componets from falling appart.

Klaus Iwik these components are not transistors. Those are all resistors.

Reference designator R7611 is a 35.7K ohm 1/20W 1% resistor in a 201 package

Reference designator R7614 is a 14.7K ohm 1/20W 1% resistor in a 201 package

Reference designator R7613 is a 47.5K ohm 1/20W 1% resistor in a 201 package

Reference designator R7613 is a 100 ohm 1/20W 5% resistor in a 201 package

@luckylastone depends on where you are located. I get mine from Mouser.com Digikey.com as well as multiple other common sources. Just checked Mouser and they do carry all of them. Careful so, shipping is expensive ;-)
