Shruthi Buttons Source and Replacement in the US

Mouser Part Numbers:
612-TL1100 Tactile Switches http://www.mouser.com/ProductDetail/E-Switch/TL1100F160Q/?qs=sGAEpiMZZMsgGjVA3toVBMVCa577J%2bXuxKck96BmEDU%3D
612-TAC-BK Buttons for switches. http://www.mouser.com/ProductDetail/E-Switch/TACBLK/?qs=sGAEpiMZZMtaJrRyqs1cXfBJPzwqv%2byP4CVE91a6bAo%3D

I’m not familiar with this hardware. I used these part numbers from the Ambika Pioneer BOM. Mouser won’t have these until late November. I’m in the US.

Is there a replacement for Mouser?

Substitutes from Mouser

This for Black 611-F1201
This for Red 611-F1203

Different manufacturer, identical dimensions-work well.

Mouser now have both of these. Anyone know if kits sold April 2014 use F1201 or TAC-BLK? I like to order additional caps and mix with caps from kits just ordered.
