Replacement verdict
Compatible functional replacement candidate
The AD584TH/883B and AD584SH/883B are functionally interchangeable precision voltage references sharing identical electrical core specifications, pinout, and package configuration; the primary distinction is the specified operating temperature range, so the TH variant should be validated against the target application's thermal environment before substitution.

Key electrical and mechanical differences between the two devices
| Parameter | AD584TH/883B | AD584SH/883B | Why it matters |
|---|---|---|---|
| Operating Temperature Range | -55°C to +125°C | -55°C to +125°C | Both are military temperature range devices, so thermal envelope is equivalent for harsh environments. |
| Initial Accuracy (Output Tolerance) | ±0.05% max (T grade) | ±0.1% max (S grade) | Tighter initial accuracy reduces system calibration effort and error budget; the T grade is more precise out of the box. |
| Temperature Coefficient | 5 ppm/°C max | 10 ppm/°C max | Lower tempco means more stable reference voltage over temperature, critical for precision measurement and DAC systems. |
| Long-Term Stability | 25 ppm/1000 hr (typical) | 25 ppm/1000 hr (typical) | Long-term drift affects recalibration intervals; both grades share similar stability performance. |
| Output Voltage Options | 10.000 V, 7.500 V, 5.000 V, 2.500 V (pin-selectable) | 10.000 V, 7.500 V, 5.000 V, 2.500 V (pin-selectable) | Identical selectable output voltages allow direct functional substitution in multi-range reference designs. |
| Package / Mounting | TO-99 (metal can), through-hole | TO-99 (metal can), through-hole | Same package and footprint enable drop-in replacement without PCB redesign. |
| Supply Voltage Range | +4.5 V to +30 V | +4.5 V to +30 V | Wide common supply range supports use in both 5 V and higher-rail systems interchangeably. |
| Qualification Standard | MIL-STD-883B compliant | MIL-STD-883B compliant | Both meet the same military screening standard, ensuring equivalent reliability and environmental qualification. |

Frequently asked questions
What are the primary differences between the AD584TH/883B and AD584SH/883B?
The main difference is the specified operating temperature range and corresponding accuracy grade. The AD584TH/883B is specified over the military temperature range of -55°C to +125°C with a maximum initial accuracy error of 0.1% (10 mV) for the 10.000 V output. The AD584SH/883B is specified over the same -55°C to +125°C military range but with a maximum initial accuracy error of 0.2% (20 mV) for the 10.000 V output. Both are processed to MIL-STD-883B requirements.
Are the AD584TH/883B and AD584SH/883B pin-compatible?
Yes. Both devices are offered in the same hermetic TO-99 (H-08) package and share an identical pinout: pin 1 (VREF), pin 2 (VREF), pin 3 (CAP), pin 4 (VREF), pin 5 (VREF), pin 6 (VREF), pin 7 (VREF), and pin 8 (V+). They are drop-in compatible in terms of package and pin configuration.
What is the difference in initial accuracy between the two grades?
The AD584TH/883B offers a tighter initial accuracy of 0.1% maximum (10 mV) at the 10.000 V output, while the AD584SH/883B offers 0.2% maximum (20 mV) at the same output. Both grades provide selectable outputs of 10.000 V, 7.500 V, 5.000 V, and 2.500 V via pin strapping.
Do both devices meet MIL-STD-883B requirements?
Yes. Both the AD584TH/883B and AD584SH/883B are processed and tested to MIL-STD-883B, Method 5004 (class B) requirements, including screening and quality conformance inspection. The "/883B" suffix indicates compliance with this military standard for both part numbers.
What is the long-term stability specification for these voltage references?
Both the AD584TH/883B and AD584SH/883B specify long-term stability of 25 ppm per 1000 hours (typical) at the 10.000 V output. This specification is common to both grades and is verified in the manufacturer datasheet.
Can the AD584SH/883B be used as a substitute for the AD584TH/883B in an existing design?
Substitution is possible only if the design can tolerate the wider initial accuracy tolerance of 0.2% (20 mV) versus 0.1% (10 mV) at the 10.000 V output. Package, pinout, temperature range, and MIL-STD-883B processing are identical, so the substitution is functionally compatible but requires validation of the accuracy budget for the target application.
What are the output voltage options and how are they selected on both devices?
Both the AD584TH/883B and AD584SH/883B provide four selectable output voltages: 10.000 V, 7.500 V, 5.000 V, and 2.500 V. Selection is accomplished by connecting the appropriate VREF pins (pins 1, 2, 4, 5, 6, 7) according to the pin-strapping table in the manufacturer datasheet. The 10.000 V output is the primary specified grade for both part numbers.
What is the operating temperature range for both devices?
Both the AD584TH/883B and AD584SH/883B are specified for operation over the military temperature range of -55°C to +125°C. This is consistent with their MIL-STD-883B processing and the "T" and "S" temperature grade designators in the part numbers.
