Component sheet for the 2SA1925 in a 198 KB PDF, labeled as a schematic though the plain part-number name suggests a manufacturer datasheet. The 2SA prefix follows the JIS convention for PNP bipolar transistors. Use the document to verify collector, base and emitter positions, check voltage and current limits, and compare gain ranks before substituting. Diode-mode testing of the junctions with a multimeter confirms a failed part, and the package drawing helps match a replacement to the original footprint.
