Compatibility and Form Factor

This Toshiba C675D-S7101 module is an M.2 Wi-Fi adapter built for the 17.3-inch Satellite C675D series. It uses the RTL-8188CE chipset and carries part numbers PA3839U-1MPC and ER. The card installs directly into the notebook's M.2 slot to restore native wireless networking.

Who This Suits and Who Should Look Elsewhere

The adapter fits owners of the specific C675D-S7101 chassis who need a direct replacement for a failed or missing wireless card. Builders working on other laptop models, different screen sizes, or desktop motherboards cannot use this module because the keying, antenna placement and firmware are tailored to this single platform.

Deciding Specification — M.2 Keying and Chipset

The single detail that decides fitment is the M.2 interface paired with the RTL-8188CE controller. Only systems wired for this exact keying and chipset will recognise the card, so verify the service manual before purchase.
