Replacement verdict
Compatible functional replacement candidate
The AD590MF and AD590MF/883B are functionally equivalent temperature transducer ICs sharing the same sensing principle, package, and pinout; the /883B suffix denotes a higher-reliability screening grade rather than a different function, so substitution is viable where the application's reliability and qualification requirements are satisfied.

Key electrical and mechanical differences between the two devices
| Parameter | AD590MF | AD590MF/883B | Why it matters |
|---|---|---|---|
| Temperature Coefficient (Sensitivity) | 1 µA/K | 1 µA/K | Defines the output current change per Kelvin; identical sensitivity ensures the same transfer function for temperature-to-current conversion. |
| Calibration Error (at 25°C) | ±0.5°C (max) | ±0.5°C (max) | Determines absolute accuracy at room temperature; matching limits allow interchangeable use without recalibration. |
| Operating Temperature Range | -55°C to +150°C | -55°C to +150°C | Defines the environmental envelope; identical ranges mean both parts suit the same harsh-environment applications. |
| Supply Voltage Range | 4 V to 30 V | 4 V to 30 V | Sets the allowable power supply window; matching ranges ensure the same circuit biasing works for both parts. |
| Nonlinearity | ±0.3°C (max, over full range) | ±0.3°C (max, over full range) | Quantifies deviation from ideal linear output; identical nonlinearity ensures comparable accuracy across the temperature span. |
| Package / Mounting | TO-52 (metal can), through-hole | TO-52 (metal can), through-hole | Determines PCB footprint and assembly method; identical packages allow direct drop-in replacement. |
| Qualification / Screening | Standard commercial/industrial grade | MIL-STD-883B compliant screening | The /883B suffix denotes military-grade screening and testing; this affects reliability assurance and procurement for defense/aerospace use. |
| Output Current Range | ~298 µA at 25°C (proportional to absolute temperature) | ~298 µA at 25°C (proportional to absolute temperature) | Defines the usable signal span; matching output ranges ensure identical signal conditioning circuitry works for both. |

Frequently asked questions
What is the difference between the AD590MF and the AD590MF/883B?
The AD590MF is the standard industrial-grade temperature transducer in a TO-52 (TO-18-style) metal can, while the AD590MF/883B is the same die and package screened to MIL-STD-883 Class B requirements for military and high-reliability applications. The /883B suffix denotes the military screening flow, not a different transfer function.
Are the AD590MF and AD590MF/883B functionally interchangeable?
Yes. Both are 2-terminal current-output temperature transducers with a nominal 1 µA/K output, a supply range of +4 V to +30 V, and a rated operating temperature range of −55 °C to +150 °C. The electrical transfer function is identical; the difference is the screening and qualification level.
What does the /883B suffix indicate on the AD590MF/883B?
The /883B suffix indicates compliance with MIL-STD-883, Method 5004, Class B screening, which includes pre-cap visual inspection, temperature cycling, constant acceleration, burn-in, and post-burn-in electrical tests, plus quality conformance inspection per Method 5005. This is a documented screening level, not a separate datasheet grade.
What is the specified accuracy grade of the AD590MF?
The AD590MF is the F-grade (highest accuracy) version of the AD590, specified with a maximum calibration error of ±0.5 °C at +25 °C and a maximum nonlinearity of ±0.3 °C over the full −55 °C to +150 °C range, per the Analog Devices AD590 datasheet.
Do both parts share the same package and pinout?
Yes. Both are supplied in the TO-52 hermetic metal can (also referred to as a TO-18-style package) with two terminals: one for the positive supply and one for the current output/return. The package outline and pin assignment are identical, so PCB footprint and mounting are the same.
Which part should be selected for a military or space application?
The AD590MF/883B should be selected when MIL-STD-883 Class B screening and traceability are required by the program. The AD590MF is intended for industrial and commercial use where the standard grade is acceptable and the military screening flow is not mandated.
Are the operating temperature ranges of the two parts the same?
Yes. Both the AD590MF and AD590MF/883B are specified over the −55 °C to +150 °C operating temperature range, consistent with the AD590 F-grade specification in the Analog Devices datasheet.
Can the AD590MF/883B be used as a drop-in replacement for the AD590MF in an existing design?
Electrically and mechanically, yes, because the die, package, and transfer function are the same. The /883B part adds screening and documentation, so it can replace the AD590MF where the higher reliability grade is acceptable; the reverse substitution is not appropriate where MIL-STD-883 Class B screening is a program requirement.
