PC817 The difference between PC 817 and EL817
The main difference between the PC817 and the EL817 is that the manufacturers are different, but their parameters are the same. The following is a detailed explanation of the differences between PC817 and EL817: Manufacturer: PC817: Made by Sharp, Japan. EL817: Although specific manufacturers may vary by brand or series, in this context, the EL817 and the PC817 have the same parameters, implying that they may belong to the same performance level or category, but are produced by different manufacturers.
The EL817 and EL817C are closer relative to the PC817 when interchanged. The following is a specific analysis: Based on chip design: EL817 and EL817C: They are both based on the same chip design, so they are closer in terms of electrical characteristics and performance. PC817: Although the functions are similar, they may be based on different chip designs, resulting in differences in parameter specifications and performance characteristics from the EL817 and EL817C.
The same, they are all optocouplers. PC817 is relatively common, and EL817 is produced by Taiwan Yiguang. PC and EL are the shortcodes of their R & D company. For example, there is a power amplifier chip called LM4871 and an XPT4871 developed in Shenzhen. The two are completely universal. An optical coupler (OC) is also known as an optoisolator or optocoupler, referred to as optocoupler.
The PC817 is a photocoupler manufactured by Sharp, Japan, and its parameters are the same as those of the EL817. In the midst of the domestic manufacturing downturn, many factories are seeking ways to reduce costs while maintaining product quality. Among them, Taiwan Yiguang's optocoupler has begun to be widely used to replace the PC817 because its price is about 30% cheaper than the PC817. After returning visits to customers, the feedback from customers using Taiwan Yiguang Optocoupler was good, with a favorable rating of 100%.
If interchanges are needed, they should be matched according to specific parameter specifications. For example, the maximum working voltage, output type, response time and other parameters of these three components are slightly different, so they can be selected according to needs. Overall, the EL817 and EL817C are closer than the PC817 because they are both designed based on the same chip. However, no matter which optocoupler is selected, it is necessary to confirm whether its parameters meet the circuit design requirements, and pay attention to whether the pin arrangement and packaging of the device are consistent with the original device.
Features of MOC3021: Suitable for isolation and control of AC circuits, and has the characteristics of high voltage resistance, high insulation resistance, low driving current, etc. Application: Widely used in occasions requiring AC circuit isolation and control, such as power transformers, power switches and other equipment. Features of PC817: It has the characteristics of high-speed switching, low power consumption, and high withstand voltage. Application: Power control, communication equipment and other fields are favored for their high-speed switching and low power consumption characteristics.
EL 817 for pc817
The main difference between the PC817 and the EL817 is that the manufacturers are different, but their parameters are the same. The following is a detailed explanation of the differences between PC817 and EL817: Manufacturer: PC817: Made by Sharp, Japan. EL817: Although specific manufacturers may vary by brand or series, in this context, the EL817 and the PC817 have the same parameters, implying that they may belong to the same performance level or category, but are produced by different manufacturers.
Whenever possible, the EL817 or EL817C is preferred for interchanges because they are based on the same chip design and are closer in terms of electrical characteristics and performance. To sum up, the EL817 and EL817C are closer to the PC817 when interchanged, but the specific selection still needs to be comprehensively considered based on the circuit design requirements and the device's parameter specifications.
The same, they are all optocouplers. PC817 is relatively common, and EL817 is produced by Taiwan Yiguang. PC and EL are the shortcodes of their R & D company. For example, there is a power amplifier chip called LM4871 and an XPT4871 developed in Shenzhen. The two are completely universal. An optical coupler (OC) is also known as an optoisolator or optocoupler, referred to as optocoupler.
The EL81 EL817C and PC817 are three different brands of optocouplers. Although they have similar functions, there may be some differences in pin layout, parameter specifications and performance characteristics. If interchanges are needed, they should be matched according to specific parameter specifications. For example, the maximum working voltage, output type, response time and other parameters of these three components are slightly different, so they can be selected according to needs.
Differences between pc 817b and el 817b
The core difference between PC817B and EL817B lies in the differences in brand and current transfer ratio (CTR), resulting in differences in application scenarios and prices. They are fully pin and package compatible, but the PC 817B has better performance and higher price, and the EL 817B has more cost advantages. Brand and origin PC817B is an original product from Sharp in Japan; EL817B is a replacement model produced by Everlight in China Taiwan.
The EL81 EL817C and PC817 are three different brands of optocouplers. Although they have similar functions, there may be some differences in pin layout, parameter specifications and performance characteristics. If interchanges are needed, they should be matched according to specific parameter specifications. For example, the maximum working voltage, output type, response time and other parameters of these three components are slightly different, so they can be selected according to needs.
