Unless someone knows better, I would suspect they're identical to OEM.

It seems that one thing that often leads to failure is draining the oil with the key turned on. The sensor was not meant to be entirely dry. Draining the sump with the sensor powered up burns out the sensor.

Reading the threads on this board, I do note that a suspicious number of these sensors fail soon after someone has an oil change performed somewhere.

I really feel bad for E90 owners who don't have a dipstick as a backup.
