I ordered the part from parts4repair (Samsung Galaxy Note Charger Port Module , MBRPSS534) and it showed up after two weeks. The new part fixed the reception but unfortunately it did not charge the battery. I contacted the seller and they sent out a replacement part free of charge. The new one only took 5 or 6 days to arrive, but I think it was more a coincidence than premium shipping. Anyway, the new part worked just fine, both reception and charging.
So in a nutshell - even parts4repair seem to have issues with QA, but still I'm happy to recommend them as a seller because of their excellent customer service.
