This 24V 30A alternator (OEM ref. 600-821-6190 / Denso 033000-56580) is an aftermarket replacement designed for Komatsu equipment using S6D95 / SAA6D95 engine arrangements, commonly referenced for PC200-6 and also seen in listings for PC200-5 / PC220-6 depending on machine configuration and serial breaks. 

Why part numbers may vary (important for PC200-6)

Even with the same engine family, alternators can differ by pulley/belt grooves (e.g., 8PK vs other layouts), bracket mounting, and wiring plug/terminal orientation. 

On your own alternator list, 600-821-6190 is also associated with 0-33000-6580 / 8PK in some catalog references, which is why we recommend confirming the belt/pulley style before ordering.
