Cross-reference sheet listing equivalents for diodes, bridge rectifiers and transistors, originally prepared as an Excel table and saved to PDF, despite being filed here as a schematic. At 599 KB it is a lookup table, not a circuit. Technicians use such lists to find a substitute when an original part is obsolete or hard to source. Always confirm a suggested replacement against both datasheets, checking voltage, current, gain, pinout and package. Equivalence tables sometimes ignore switching speed or power ratings.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @pdf_servicemanual. Enginerys does not host this file.
