Replacement verdict
Compatible functional replacement candidate
The AD584SH and AD584TH/883B are functionally interchangeable precision voltage references sharing the same core architecture, package, and pinout, with the TH/883B variant offering a tighter temperature-coefficient grade and military screening. Designers can substitute between them where the tighter drift specification of the TH/883B is not mandatory, but should confirm grade-dependent accuracy tolerances against the target application before committing to a drop-in swap.

Key electrical and mechanical differences between the two devices
| Parameter | AD584SH | AD584TH/883B | Why it matters |
|---|---|---|---|
| Initial Accuracy (Output Voltage Tolerance) | ±5 mV max (at 10.000 V) | ±2.5 mV max (at 10.000 V) | Tighter initial tolerance means the reference output is closer to nominal without trimming, directly affecting system calibration accuracy. |
| Temperature Coefficient | 5 ppm/°C max | 5 ppm/°C max | Drift over temperature determines reference stability in precision measurement and data acquisition over the operating range. |
| Operating Temperature Range | -55°C to +125°C | -55°C to +125°C | The rated temperature span defines where the specified accuracy and drift limits are guaranteed, critical for military and industrial use. |
| Qualification / Screening | Standard industrial/military grade | MIL-STD-883B compliant screening | 883B screening ensures lot-level reliability testing and traceability required for defense and aerospace applications. |
| Package | TO-99 (metal can), 8-pin | TO-99 (metal can), 8-pin | Package and pinout determine board footprint and thermal behavior; identical packages allow drop-in substitution. |
| Output Voltage Options | Pin-selectable 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 | Multiple selectable outputs let one part serve several reference levels, simplifying inventory and design reuse. |
| Long-Term Stability | 25 ppm/1000 hr (typical) | 25 ppm/1000 hr (typical) | Long-term drift affects recalibration intervals and lifetime accuracy of the reference in fielded equipment. |
| Supply Voltage Range | +4.5 V to +30 V | +4.5 V to +30 V | Wide supply range allows operation from various rails and improves compatibility with existing system power architectures. |

Frequently asked questions
What are the key differences between the AD584SH and AD584TH/883B?
Both are precision voltage references in the AD584 family, but they differ in grade and screening. The AD584SH is specified for the extended industrial/military temperature range of −55°C to +125°C in a TO-99 hermetic package, while the AD584TH/883B is a military-grade device screened to MIL-STD-883 Class B requirements, also in a TO-99 package, with guaranteed performance over the −55°C to +125°C range. The /883B suffix indicates compliance with MIL-STD-883 screening and test methods, which the SH grade does not carry.
Are the AD584SH and AD584TH/883B pin-compatible?
Yes. Both devices are offered in the same TO-99 (H) hermetic package with the same pinout, so they are pin-compatible and can be interchanged on an existing PCB footprint. Electrical substitution still requires verifying that the grade-specific specifications meet the application requirements.
What output voltage options do the AD584SH and AD584TH/883B provide?
The AD584 is a pin-programmable precision voltage reference that provides four output voltages: 10.000 V, 7.500 V, 5.000 V, and 2.500 V, selected by connecting the appropriate pins. Both the SH and TH/883B grades support these same four output settings.
What is the significance of the /883B suffix on the AD584TH/883B?
The /883B suffix indicates that the device has been processed and screened in accordance with MIL-STD-883, Method 5004, Class B requirements, including burn-in, temperature cycling, and other reliability screening steps. This makes it suitable for military and high-reliability applications where documented screening and traceability are required. The AD584SH does not carry this MIL-STD-883 Class B screening designation.
What is the operating temperature range for both devices?
Both the AD584SH and AD584TH/883B are specified for operation over the −55°C to +125°C temperature range, making them suitable for military and extended-temperature applications. This is in contrast to commercial and industrial grades of the AD584, which have narrower specified ranges.
Can the AD584SH be used as a drop-in replacement for the AD584TH/883B in a military application?
Functionally and pin-wise, yes, since both are TO-99 devices with the same pinout and output options. However, for military or high-reliability programs that require MIL-STD-883 Class B screening documentation, the AD584TH/883B should be retained, because the AD584SH does not carry the /883B screening qualification. The substitution should be approved against the program's reliability and procurement requirements.
What package type do the AD584SH and AD584TH/883B use?
Both devices are supplied in the TO-99 (H) hermetic metal-can package, which provides environmental protection and is suitable for military and high-reliability applications. The hermetic package helps ensure long-term stability and reliability in harsh environments.
