I have a schematic for a timer circuit I have everything I need
exept a U1 555 timer but I do have a TLC 555 timer can I switch
the U1 555 timer for the TLC 555 timer?

That's a link to a file on your hard drive, which we can't see. You need to either:
1. Use the "Go Advanced" button, then click "Manage Attachments" in the message editor to attach the picture (as a clickable thumbnail) to your post, or
2. Create an album ("My Account"--> "My Albums"), upload the picture to an album from your hard drive, then paste a link to the picture (on this site, not your hard drive) into your post.
On your schematic, U1 is the '555' it's not a special kind. See you have R1, R2 and R3? Which are all resistors. If there were more than one 'chip' they would be named U2, U3 etc. .
The TLC555 will work OK at 3V, to suit your relay.
Be sure to add a diode across the relay coil to protect the 555 from the relays back EMF, do you know how to do that.?

In addition, you should remember that a TLC555 is a CMOS device and can be destroyed with stray static. I have killed a few myself by accidentaly touching them while not protected. A more robust 555 timer would be better.
