Search for "Towers International Transistor Selector PDF" or "ECG Replacement Guide PDF" – these are scanned versions of the classic books, ideal for workshops without internet.
There is rarely a "perfect" equivalent. You are looking for a component that is "good enough" to work in that specific application.
Many books group transistors into families (e.g., "Small Signal Low Noise," "Switching," "Power Darlington"). Never substitute a power transistor (e.g., 2N3055) for a small-signal device (e.g., 2N3904) even if the book lists them under the same number. Read the category heading.
