There is a new SOT-23 Case 318-08 in Table 6 on page 278 which lists MMBF0202PLT1. The Motorola might possibly know the difference and might provide the right answer to you. Traditional Motorola substitutes/replacements are not available and posted discontinued devices do not include your transistor. [sig][/sig]
