PDF of 363 KB for the 2SK192A, listed among schematics but named after a single JIS part, with an A suffix that the name explicitly includes. In Japanese numbering, 2SK covers N-channel field-effect transistors. Use the document to read the pinout, package drawing and ratings, and to see how the suffixed version is specified. When substituting, make sure the replacement matches the suffix variant or exceeds its limits, and observe antistatic precautions while handling the new transistor.
