Features: This mechanism is compatible with various brands of CD players and HiFi systems, as many manufacturers use the SF-P101N laser. Please note that there are two versions of the SF-P101N laser: one with 16 pins on the laser ribbon connector and another with 15 pins. The 16-pin version is provided here, as it is the most common. The 16-pin and 15-pin versions are not interchangeable. The SF-P101N laser installed on this mechanism is suitable for use in multiple brands of CD players and HiFi systems. The laser model number is printed on the laser housing. If your original laser is labeled SF-P101N, this mechanism is compatible. Confirm by checking that the edge connector has 16 pins. If your CD player or HiFi system uses an SF-P101N laser, replacing the entire mechanism can provide an effective repair, as all moving parts in the CD reading assembly are renewed.
