Datasheet for the 5HP01N part in PDF form, about 27 KB. No device or motherboard is named; the code with an N ending appears to be a package variant of the 5HP01 series.

Combined datasheet PDF of 210 KB covering the 4N25 to 4N28 and 4N35 to 4N37 optocouplers, although indexed as a schematic.

Compact 38 KB PDF datasheet for the 2SD2142K, an NPN transistor named in the Japanese JIS scheme, where the trailing letter marks a specific package or variant.

The 2SD1879 is documented in this 94.5 KB PDF, indexed as a schematic yet most likely a manufacturer datasheet for the part.

The 3SK219 is covered by this compact PDF of roughly 30 KB, indexed as a schematic but by its name a part datasheet.

A 41.8 KB PDF named for the 2SD2457 with an E tag, filed as a schematic. By the JIS scheme, 2SD marks an NPN bipolar transistor, so expect a component reference rather…

Listed as a schematic, the 307 KB PDF titled 2SK118 is by name a component datasheet for a Japanese JIS-numbered device.

Named for the 2SK2824 transistor, this 305 KB PDF is indexed as a schematic but is most likely a single-part datasheet.
