I tested 7 SMD "NXP" marked 612's just now (old Fluke DMM set to 200 kohm scale):

ohmmeter reading across pins 1 and 2:? 11.1k; 11.6k; 11.4k; 11.0k; 11.3k; 11.3k; 11.5k ohms.

The early NC40B kit 612s had some defective ones. An easy check we found is ohmmeter across pins 1 and 2. Good ones are in the 10-50 kohm range,? bad ones are open or much higher or much lower.
