What brand models can 2SC4672 SOT-89 UTC replace

2SC4672 SOT-89 Youshun (UTC) is an NPN transistor, and its performance parameters and packaging form make it capable of replacing similar models from other brands in certain applications. However, it should be noted that although some transistors may have similar electrical characteristics, there may be differences in their specific parameters, packaging, heat dissipation performance, and reliability. Therefore, before substitution, it is necessary to carefully compare these parameters and ensure that the selected substitute model can meet the requirements of the circuit.

The following are some brands and models that may have similar electrical characteristics to 2SC4672 SOT-89 Youshun (UTC) and could be used as alternative options (please note that these suggestions are for reference only, and specific alternatives need to be determined based on actual applications and testing):

ROHM Semiconductor's 2SC4672Q or 2SC4672T100:
These two transistors have similar electrical characteristics to 2SC4672, with NPN type, 50V collector emitter voltage, and higher current carrying capacity.
The packaging form may vary, but if it is common packaging such as MPT or TO-243, and the circuit does not have special requirements for packaging size and heat dissipation performance, they may be considered as alternative options.
Similar models of other brands:
NPN type transistors with a voltage of around 50V, produced by other semiconductor manufacturers, and with current carrying capacity and DC current gain parameters similar to 2SC4672, may also be used as alternative options.
However, due to differences in manufacturing processes, material selection, and quality control between different brands, the reliability and lifespan of these alternative models may vary. Therefore, when choosing alternative models, it is necessary to comprehensively consider factors such as their performance, price, and supplier reputation.
It should be emphasized that any alternative needs to be tested and validated in practical applications. Before substitution, it is recommended to obtain a detailed data manual for the substitute model and carefully compare its electrical characteristics, packaging form, heat dissipation performance, and other differences with 2SC4672. In addition, it is necessary to consider factors such as the production status, supply situation, and price of alternative models to ensure that the selected alternative models can meet the requirements of the circuit and have reasonable cost-effectiveness.

In summary, 2SC4672 SOT-89 Youshun (UTC) may be able to replace similar models from certain other brands, but the specific substitutability still needs to be determined based on actual application and testing. When selecting alternative models, multiple factors need to be considered comprehensively to ensure that the performance and reliability of the circuit are not affected.
