The first-generation AFF6 to 55, AM200 to 600, and AMD100 to 800 series were discontinued in 1994, and the production of their elements and maintenance components have also been terminated. In addition, the old elements are not interchangeable with those of the new product. Replace the product as a whole.
No, mounting is not possible. Replace each product as a whole. The case assembly of the early stage second-generation AFF2B to 22B, AM150 to 550, and AMD150 to 550 is not interchangeable with that of the later stage second-generation AFF2C to 22C, AM150C to 550C, and AMD150C to 550C. Even if the mounting screws on the body are in the same position, the element will not fit inside.
