REF195 Vs LT1461 drift comparison

Question

We are looking to replace the LT1461 refernce with REF195FS. Most specs are clear, however the drift is specified differently. REF195FS drift 1000hrs 1.2mV @ 125 degC. LT1461: 60 ppm/&radic;kHr specified at 30&deg;C. What would be the drift of the REF195FS at 30&deg;C after 1000hrs?

Hi AdamGoldsmith , 
 
 I looked for a data for REF195 LTD at 30&deg;C after 1000 hours but unfortunately there are no recorded test data for it. I found LT1461 characterized at 130&deg;C on DN229 (120 ppm or 0.6mV), I hope this can help with your comparison. Thanks! 
 
 Best regards,
