Target Device & Purpose

This Broadcom BCM4331 wireless card combines 802.11n Wi‑Fi and Bluetooth in a single module. It uses a 12+6 pin interface and is built for MacBook Pro models A1398 and A1425 released in 2012 and 2013. The part replaces Apple service numbers 607‑8356, 607‑9689 and 607‑9690.

Who It Suits & Who Should Look Elsewhere

Owners of the listed MacBook Pros needing a direct‑fit replacement for a failed AirPort/Bluetooth card will find the correct connector and firmware compatibility here. Buyers whose laptops use a different pin layout, a newer Wi‑Fi standard, or a non‑Apple form factor cannot use this module.

Deciding Specification

The 12+6 pin connector and BCM4331 chipset determine fit; only systems designed for this exact interface and the supported Apple model numbers will recognise and drive the card.

Questions about this item

How do I install the 12+6Pin interface card into a MacBook Pro A1398?

Power down the laptop, remove the bottom case, disconnect the battery, then seat the 12+6Pin connector firmly into the AirPort slot until it clicks; the step most people miss is reconnecting the three antenna cables to the correct numbered posts.

What maintenance will the BCM94331 module need over time?

No scheduled maintenance is required; if wireless throughput drops below the 433 Mbps link rate or Bluetooth becomes unreliable, the module itself would be replaced rather than serviced.

What thermal limit appears first during sustained 802.11N traffic?

The card throttles when its internal temperature reaches the vendor-defined trip point, reducing the 433 Mbps PHY rate to protect the Broadcom BCM4331 silicon.
