Precision 2.5v reference

[bmohandes]

Hi,
I am looking for a precision 2.5V reference with low drift.
I am currently using a REF3425IDBVR from TI, but this part is very expensive and difficult to find.
Brokers are charging eye watering $25 each.
I would like to find an alternative in the same footprint with:
- SOT23-6
- 2.5V
- Initial accuracy: ±0.05%
- Temperature coefficient : 6 ppm/°C (maximum) or better
- Excellent long-term stability 25 ppm/1000 hrs

Can anyone suggest an alternative?
Thanks,
Bijan
