The Fairchild S035928  (P/N 151-0342-00) is a PNP Si small signal transistor.

Package: TO-106

NSN: 5961-00-246-2427

RPR: Tektronix RPR for 151- Transistors page 456

Equivalents

The Sphere Tek cross-reference indicates that 2N4249 is equivalent.

Additional searching on the internet for the NSN will lead to 2N4249 (same number as Sphere provides) as well as 2N4429 (note the similarity - likely a transposition). The latter is definitely incorrect, as that is an NPN RF power transistor and not in TO-106 package.

Specs

Exact specs of the 151-0342-00 are unknown; the 2N4249 is 60V, 0.1A, hFE 100-300.
