I am looking for a STAC2942B-12W wich seems to be out of production, is it equivalent to the STAC2942B, or to the STAC2942BW? thanks

Welcome, @Andrea Mazza​, to the community!

Unfortunately, you have interpreted the letter "I" as digit "1", the correct ordering code was STAC2942B-I2W.

Anyway, this particular RF transistor was discontinued a long time ago, but was also not generally available, as it was a custom device that only the customer had documentation on.
