If you'd like, I can also generate a (common types like 2N3904, BC548, A1015, C1815, TIP31C, IRFZ44N, etc.) formatted for a book or spreadsheet. Would that help?

For over half a century, the "transistor equivalent book" has been the silent hero of repair shops, hobbyist workbenches, and engineering labs. When a vintage Germanium transistor in a 1960s radio fails, or an obsolete Japanese silicon part in a 1980s amplifier goes up in smoke, these books provide the lifeline: a modern or alternative component that will work seamlessly in its place. These are excellent for fieldwork
Several paid and free apps (e.g., "Transistor Database," "Electronics ToolKit") have digitized old Towers and ECG databases. These are excellent for fieldwork. Search for "all transistor equivalent book app" in your app store.
) : The substitute must be able to handle at least as much current as the part it is replacing. Original Transistor Common Equivalents MPSA42 2N3904, BC547, KST42, or MMBTA42 BC547 2N3904, 2N2222 (Note: check pinouts) SMD Types Often have a 2N or BC series "conventional" equivalent
