-The [https://www.sphere.bc.ca/oldsite/test/tekequiv.html Sphere Tek cross-reference] indicates that 2N4249 is equivalent.
+RPR: [[Media:Tek RPR 151- Transistors.pdf|Tektronix RPR for 151- Transistors]], pg 456
-Additional searching on the internet finds various sites stating that this Tek P/N is NSN 5961-00-246-2427. Searching that number will lead to 2N4249 (same number as Sphere provides) as well as 2N4429 (note the similarity - likely a transposition). The latter is incorrect, as that is an NPN RF power transistor and not in TO-106 package.
