Can't say yes to that specifically from memory but can only say I've used both with success. The Radio Shack stuff fixed my Camry's non-functioning door switches to like new operation, but I worked them on/off as I sprayed. It has a lubricate as well as cleaner. The CRC stuff has no lubricant and will evaporate dry. The CRC cleaner says; "...safely dissolve dirt, dust, grease, flux and other contaminants on contact." I guess you could spray as you plug/unplug connectors to rub/clean/wash off crud. I just thought trying to get tiny eraser into contacts would be a problem.
