) matching, making it excellent for audio driver stages requiring high fidelity.
The only practical way to adapt an ECB transistor for an EBC PCB footprint is to carefully cross the base and collector legs, commonly known as "leg twisting". As shown in the example for replacing 2SC1124 with KSC2690A, you need to cross them in an "X" pattern and insulate the leads with heat shrink tubing to prevent shorts when crossing. c1124 transistor datasheet better
If you are working with high-fidelity audio or require a faster transistor, the (or its higher voltage sibling, the Go to product viewer dialog for this item. ) is an outstanding choice. Voltage Rating: 200 V ( VCEOcap V sub cap C cap E cap O end-sub Current Rating: 0.1 A (100 mA) Power Dissipation: 1.2 W Transition Frequency ( fTf sub cap T ): 150 MHz Verdict: Because the ICcap I sub cap C is much lower than the Go to product viewer dialog for this item. , you should only use the Go to product viewer dialog for this item. ) matching, making it excellent for audio driver
Use the or "Translated" option. Look for the datasheet uploaded by Hitachi from 1983 – it has the clearest SOA graph. If you are working with high-fidelity audio or
Since "better" can mean different things depending on your goal (repairing vintage gear vs. a modern upgrade), here is a breakdown of the datasheet specs and the best modern replacements.
