This is a genuine Tyco Electronics relay. Not a counterfeit Hongfa relay marked as a Tyco. Look for the correct pattern on the bottom cover. Fake parts are potted. You can clearly see the difference. 

Not remarked Honfa relays.
Look for the crosshatched pattern on the bottom. Counterfeit parts do not have the crosshatch, but, are liquid epoxy potted. For reference look at the back of the Hongfa JQC-16F-012-2ZST. Counterfeit parts will look identical to the Hongfa on the bottom.
This auction is for four Tyco V23084-C2001-A303 relays commonly used to control the door locks and rear power windows in various BMWs.
