Replacement verdict
Compatible functional replacement candidate
The AD584TH/883B and AD584JH are functionally compatible precision voltage references sharing the same core architecture, output voltage options, and package footprint, making them viable substitutes in most designs. The primary distinction lies in operating temperature range and screening grade, where the TH/883B variant is specified for the full military temperature range while the JH variant is characterized for commercial temperature operation. Designers should validate thermal margin and long-term stability requirements against the target application before substituting the commercial-grade device for the military-grade part.

Key electrical and mechanical differences between the two devices
| Parameter | AD584TH/883B | AD584JH | Why it matters |
|---|---|---|---|
| Operating Temperature Range | -55°C to +125°C | 0°C to +70°C | The military-grade TH/883B variant supports full military temperature operation, while the JH commercial grade is limited to commercial ranges; this affects suitability for harsh environments. |
| Grade / Screening | Military grade, 883B screened (MIL-STD-883) | Commercial grade | 883B screening ensures enhanced reliability and testing for aerospace/defense use; the commercial part lacks this screening and is intended for benign environments. |
| Package / Case | TO-99 (metal can), 8-pin | TO-99 (metal can), 8-pin | Both use the same hermetic TO-99 metal can package, so footprint and mounting are compatible for direct board replacement. |
| Initial Accuracy (Output Tolerance) | ±0.05% max (grade T) | ±0.1% max (grade J) | Tighter initial accuracy reduces system calibration effort and error budget; the TH/883B grade offers better guaranteed accuracy than the J grade. |
| Temperature Coefficient | Lower tempco (T grade, tighter spec) | Higher tempco (J grade) | Lower temperature coefficient maintains output stability over temperature, critical for precision references in wide-temperature applications. |
| Output Voltage Options | Pin-programmable: 10.000 V, 7.500 V, 5.000 V, 2.500 V | Pin-programmable: 10.000 V, 7.500 V, 5.000 V, 2.500 V | Identical selectable output voltages mean the parts are functionally interchangeable in terms of reference levels provided. |
| Supply Voltage Range | Up to +30 V input | Up to +30 V input | Same maximum supply voltage allows use in the same circuit rails without redesign. |
| Long-Term Stability | Specified long-term drift (premium grade) | Specified long-term drift (standard grade) | Long-term stability affects recalibration intervals; premium grades typically guarantee tighter drift over time. |

Frequently asked questions
What are the key differences between the AD584TH/883B and the AD584JH?
The AD584TH/883B is the military-grade version of the AD584 voltage reference, processed to MIL-STD-883B screening requirements and specified over the full −55°C to +125°C operating temperature range. The AD584JH is the commercial/industrial grade version specified over 0°C to +70°C. Both are pin-compatible precision 10 V references in a TO-99 metal can package, but they differ in temperature screening, guaranteed specifications over temperature, and qualification level.
Are the AD584TH/883B and AD584JH electrically and functionally interchangeable?
Functionally, both devices provide a pin-programmable output of 10.000 V, 7.500 V, 5.000 V, or 2.500 V and share the same TO-99 pinout and internal architecture. However, they are not fully interchangeable in all applications because the TH/883B guarantees its specifications over the extended −55°C to +125°C range, while the JH guarantees specifications only over 0°C to +70°C. Substitution in the reverse direction (JH in place of TH/883B) is not valid for military or wide-temperature applications.
What is the difference in temperature grade and screening between the two versions?
The AD584TH/883B is specified over −55°C to +125°C and is screened per MIL-STD-883B, including burn-in and other military screening tests. The AD584JH is specified over 0°C to +70°C and receives standard commercial processing. The TH/883B suffix indicates the military temperature grade and 883B screening, while the JH suffix indicates the commercial temperature grade in a TO-99 package.
Do both parts use the same package and pin configuration?
Yes. Both the AD584TH/883B and AD584JH are supplied in the TO-99 hermetic metal can package with the same pinout, allowing the same PCB footprint and socket. The difference lies in the temperature grade and screening level, not in the package outline or pin functions.
What output voltage options do the AD584TH/883B and AD584JH support?
Both devices are pin-programmable to provide 10.000 V, 7.500 V, 5.000 V, or 2.500 V outputs. The output voltage is selected by connecting the appropriate pin, and both grades share the same programming scheme and internal reference architecture.
Can the AD584JH be used as a drop-in replacement for the AD584TH/883B in a military design?
No. The AD584JH is only specified over 0°C to +70°C and is not screened to MIL-STD-883B, so it does not meet the temperature range or screening requirements of the AD584TH/883B. For military or extended-temperature applications, the TH/883B grade must be used to maintain guaranteed performance over −55°C to +125°C.
Which grade should be selected for an industrial application versus a military application?
For industrial or commercial applications operating within 0°C to +70°C, the AD584JH is the appropriate grade. For military, aerospace, or applications requiring guaranteed performance over −55°C to +125°C and MIL-STD-883B screening, the AD584TH/883B should be selected. The choice depends on the required temperature range and qualification level rather than on differences in basic electrical function.
