Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AD590KF is determined by strict alignment across the following critical parameters:

• Sensor Type & Output: Analog current output for local temperature measurement
• Temperature Range: -55°C to 150°C operating and sensing range
• Accuracy Specification: ±2.5°C at 25°C test condition
• Supply Voltage: 4V to 30V operating range
• Package & Mounting: 2-CeramicFlatPack surface mount configuration
• Electrical Equivalence: Identical functional output characteristics and signal conditioning

The AD590KF/883B qualifies as a direct substitute based on matching all electrical specifications, temperature range, accuracy, supply voltage, and physical packaging. Differences in compliance certifications do not affect functional interchangeability for applications where such certifications are not mandated.

Parameter Comparison

Engineering Selection Recommendations

The AD590KF and AD590KF/883B are electrically and mechanically equivalent temperature sensors. Selection between these parts depends on regulatory and compliance requirements specific to the application:

AD590KF is the appropriate choice for applications requiring ROHS3 compliance certification or where regulatory mandates restrict the use of non-compliant components.

AD590KF/883B is functionally identical and suitable for applications where RoHS compliance is not a requirement. This variant maintains full electrical equivalence, identical temperature measurement accuracy, and compatible packaging.

Both parts share identical inventory status classifications and REACH compliance status. The choice between them is determined solely by compliance certification requirements, not by functional performance or electrical characteristics.

Frequently Asked Questions (FAQ)

Q: Can AD590KF/883B be used as a direct replacement for AD590KF in all applications?

A: The AD590KF/883B is electrically and mechanically equivalent to the AD590KF. Substitution is valid for applications where RoHS3 compliance is not mandated. If your application or end-market requires RoHS3 certification, the AD590KF must be used.

Q: What is the difference between these two part numbers?

A: Both parts are identical analog temperature sensors with the same electrical specifications, temperature range (-55°C to 150°C), accuracy (±2.5°C), and 2-CeramicFlatPack surface mount packaging. The primary difference is RoHS compliance status: AD590KF is ROHS3 compliant, while AD590KF/883B is not.

Q: Are the package dimensions identical between AD590KF and AD590KF/883B?

A: Yes. Both components use the 2-CFlatPack ceramic flat package with identical surface mount configuration and footprint.

Q: What supply voltage range do these sensors require?

A: Both the AD590KF and AD590KF/883B operate with a supply voltage range of 4V to 30V.

Q: What is the temperature measurement accuracy of these sensors?

A: Both sensors provide ±2.5°C accuracy at a 25°C test condition across the full -55°C to 150°C operating range.

Q: Can these sensors be used interchangeably in PCB designs?

A: Yes. Both parts share identical electrical characteristics, output type (analog current), and 2-CeramicFlatPack surface mount packaging, making them mechanically and electrically interchangeable at the PCB level.
