Replacement verdict
Compatible functional replacement candidate
The AD584SH and AD584SH/883B are functionally equivalent precision voltage references sharing the same core architecture, package, and pinout; the /883B suffix denotes compliance with MIL-STD-883 screening and qualification rather than a change in electrical function. The primary differentiator is the military-grade screening and qualification flow, which must be validated against the target application's reliability and procurement requirements before substitution.

Key electrical and mechanical differences between the two devices
| Parameter | AD584SH | AD584SH/883B | Why it matters |
|---|---|---|---|
| Manufacturer Part Number | AD584SH | AD584SH/883B | The /883B suffix denotes a military-grade screening variant, so the exact ordering code determines the qualification level received. |
| Qualification / Screening | Standard industrial/military grade | MIL-STD-883 Method 5004 Class B screened | The 883B version is screened to MIL-STD-883, which is required for defense and high-reliability applications; the base SH part is not. |
| 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 mean the parts are functionally interchangeable in a given circuit design. |
| Initial Accuracy (10 V output) | ±5 mV max | ±5 mV max | Matching initial accuracy confirms both parts meet the same reference tolerance for precision measurement circuits. |
| Temperature Coefficient | 5 ppm/°C max | 5 ppm/°C max | Identical tempco ensures comparable drift performance over temperature, critical for stable voltage references. |
| Package | TO-99 (metal can), 8-pin | TO-99 (metal can), 8-pin | Same package and pinout allow direct drop-in replacement on an existing PCB footprint. |
| Operating Temperature Range | -55 °C to +125 °C | -55 °C to +125 °C | Matching extended temperature range confirms both parts are suitable for the same harsh-environment applications. |
| Supply Voltage Range | +4.5 V to +30 V | +4.5 V to +30 V | Identical supply range means the same power rail can drive either part without redesign. |
| Output Current Capability | 10 mA source / 5 mA sink | 10 mA source / 5 mA sink | Same drive capability ensures equivalent load-handling behavior in the target circuit. |

Frequently asked questions
What is the difference between the AD584SH and AD584SH/883B?
The AD584SH is the standard industrial-grade version of the AD584 precision voltage reference in a TO-99 hermetic metal can, while the AD584SH/883B is the same die and package screened to MIL-STD-883 Class B (883B) military qualification requirements. The /883B suffix denotes additional screening and quality conformance testing rather than a different functional specification.
Are the electrical specifications of the AD584SH and AD584SH/883B identical?
Both parts share the same core AD584 electrical specifications, including four pin-programmable output voltages of 10.000 V, 7.500 V, 5.000 V, and 2.500 V, low output drift, and the same operating temperature range of -55°C to +125°C for the H-grade package. The /883B version adds military screening and quality conformance inspection per MIL-STD-883 rather than changing the datasheet electrical limits.
Can the AD584SH/883B be used as a drop-in replacement for the AD584SH?
Functionally and pinout-wise, both are the same AD584 device in the same TO-99 package, so they are interchangeable in terms of electrical function and footprint. However, the /883B part carries military screening documentation and is typically used where MIL-STD-883 compliance is required, so substitution should be validated against the program's quality and documentation requirements.
What does the /883B suffix indicate on the AD584SH/883B?
The /883B suffix indicates the device has been processed and screened in accordance with MIL-STD-883, Class B requirements, which include additional burn-in, temperature cycling, and quality conformance inspection steps beyond standard commercial or industrial screening. This makes the part suitable for military and high-reliability applications requiring documented 883B compliance.
What package do the AD584SH and AD584SH/883B use?
Both the AD584SH and AD584SH/883B are supplied in a hermetic TO-99 metal can package (H-grade), which provides a sealed metal enclosure suitable for the extended -55°C to +125°C operating temperature range. The package and pinout are identical between the two variants.
What output voltages can the AD584SH and AD584SH/883B provide?
Both devices are pin-programmable precision voltage references offering four output voltages: 10.000 V, 7.500 V, 5.000 V, and 2.500 V, selected by connecting the appropriate programming pins. The reference is based on a buried Zener diode for low noise and long-term stability.
Which part should be selected for a military or high-reliability program?
For programs requiring MIL-STD-883 Class B screening and documented quality conformance, the AD584SH/883B should be selected. The standard AD584SH is appropriate for industrial and commercial applications where 883B screening documentation is not required, since both share the same electrical function and TO-99 package.
