| FFF Compatibility | The part uses the identical TO-3 metal can package with the same footprint and physical pin configuration (case is Emitter, Pin 1 is Collector, Pin 2 is Base).It shares the exact physical TO-3 dimensions, construction, and metal can enclosure.While electrically and thermally identical, it is the standard industrial version and does not carry the high-reliability MIL-STD-883 military-grade screening or qualification. | Housed in a much smaller TO-39 (TO-CAN NDT) package with 3 leads instead of a 2-pin TO-3 package, requiring a PCB footprint and mechanical layout redesign.The physical form factor is a small TO-39 metal can compared to the large TO-3 metal can of the original part.Fully matches the electrical performance, protection limits, temperature limits, and MIL-STD-883 high-reliability qualification of the original part. | ||
 AI Summary | LM195K/883 by National Semiconductor: Bipolar (BJT) Transistor NPN - Darlington 42 V Through Hole TO-3-2. | The LM195K is the industrial/commercial equivalent of the queried part in the same TO-3 metal can package. It provides the exact same protective features and electrical specifications over the full -55°C to +150°C range, but lacks the military screening.
| This is a same-family sibling screened to military standards but packaged in a smaller TO-39 metal can. It is functionally and environmentally compatible, though it requires a physical board redesign.
