Notes
- KHS-400R seems to be a rebadged Sanyo SF-HD7 with a different plastic cap to remove the "HD7" labelling present on the SF-HD7; they are completely interchangeable
- KHS-400B and KHS-400C are electrically compatible, but differ in thickness of the base, making them mechanically incompatible (putting a KHS-400C in place of a KHS-400B will seem to work at first, but the flex cable will bend heavily once the laser reaches the outer area while moving)
- KHS-400C and KHS-400R / SF-HD7 are mechanically fully compatible, but require different calibration data for MechaCon
- There are 2 different lens assemblies for KHS-400B, which require different calibration data for MechaCon: T487 (white ring around lens) and T609K (yellow ring around lens). Some early T609K have a white ring around the lens. These lasers have a violet marking at the adjustment screw.
- KHS-400B (with T487 lens assembly) can fully replace KHS-400A, but not vice versa (mechanical reasons). KHS-400B with T609K can also be used, but requires different calibration data for MechaCon.
- PSX consoles always have 2 lasers: One KHS-400C (for PS2 games only) and KWS-200A (XPD-001 motherboard) or SF-DB11 (XPD-005 motherboard). Every disc will first be detected by the KWS-200A / SF-DB11, so if this laser is broken, the console also won't read PS2 games, since the KHS-400C only becomes active once a PS2 game has been detected
- The drive mechanisms of earlier and later PSX consoles are completely different (except the KHS-400C), so you can't replace a KWS-200A with a SF-DB11 (same goes for vice versa)
