The Maxim Integrated MAX6250BESA+ is a series, buried-zener voltage reference delivering a fixed 5V output with ±0.1% initial accuracy and a temperature coefficient of 7ppm/°C.
The ±0.1% tolerance and 7ppm/°C drift define the reference's contribution to system error budget.
No official direct replacement is listed in the manufacturer's documentation. For now the part is active; if obsolescence occurs, the closest functional match would be another 5V series buried-zener reference in 8-SOIC with similar drift and noise specs — check the MAX6250 family for higher-grade (A/E) or lower-grade (C) tolerance options.
