For life time of product, please refer: we have done qualification tests according to JEDEC standards (see our qualification report). The typical assumption of accelerated lifetime tests like for instance a THB or HTOL is that 1000 h of such a test represents the field load of 10 years. We have passed such tests. Beyond that, we have the sensors in the field since 2016 without issues and are also not aware that BMEs would fail after a certain number of years of operation.
For supply time, it is better to check with sales guy for the business information if your had distributor.
