Features: This mechanism is compatible with various brands of CD players and HiFi systems, as many manufacturers use SF-P101N lasers. 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 type. The 16-pin and 15-pin versions are not interchangeable. The SF-P101N laser mounted on this mechanism can be used in many different brands of CD players and HiFi systems. The laser model is printed on the housing of the laser. If your faulty laser is labeled SF-P101N, this mechanism may be suitable. Confirm by counting the pins on the edge connector to ensure there are 16. 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 of the CD reading mechanism are renewed.
