AD590MH Temperature Sensor - Equivalent & Substitute Parts

Part Overview

The AD590MH is an analog temperature sensor manufactured by Analog Devices Inc., designed for local temperature measurement across a range of -55°C to 150°C. This component operates as a precision current output device with supply voltage requirements between 4V and 30V. The AD590MH is classified as an active product with full RoHS3 compliance and REACH unaffected status, making it suitable for modern industrial and commercial applications requiring reliable thermal monitoring.

Substitute parts become necessary when addressing inventory constraints, lead time requirements, or specific packaging preferences while maintaining functional compatibility within defined electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AD590MH is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Sensor Type: Analog, Local
• Output Type: Analog Current
• Voltage Supply Range: 4V ~ 30V
• Package / Case: TO-206AC, TO-52-3 Metal Can
• Mounting Type: Through Hole
• Base Product Number: AD590

Allowable Variation Parameters:

• Sensing Temperature Range: May differ within operational limits
• Accuracy: May vary based on application requirements
• Packaging Format: Bulk or Box acceptable

The AD590JH qualifies as a substitute part for the AD590MH based on shared electrical characteristics, identical package specifications, and common base product lineage within the AD590 series.

Parameter Comparison

Engineering Selection Recommendations

Both the AD590MH and AD590JH are active products with full RoHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing standards.

AD590MH Selection Criteria:

• Applications requiring sensing temperature range of -55°C to 150°C
• Systems demanding accuracy of ±0.5°C at 25°C test condition
• Packaged in Box format for controlled inventory management

AD590JH Selection Criteria:

• Applications with sensing temperature requirements within -40°C to 125°C range
• Systems where accuracy tolerance of ±5°C at 25°C is acceptable
• Bulk packaging format suitable for high-volume production environments
• Scenarios where extended inventory availability is prioritized

Both parts share identical electrical supply requirements (4V ~ 30V), output characteristics (Analog Current), and physical package specifications (TO-52-3 Metal Can, Through Hole mounting), enabling direct functional substitution within the defined parameter constraints.

Frequently Asked Questions (FAQ)

Q: Can AD590JH replace AD590MH in all applications?

A: AD590JH functions as a substitute only when the application's temperature sensing range requirement falls within -40°C to 125°C and accuracy tolerance of ±5°C is acceptable. Applications requiring the full -55°C to 150°C range or ±0.5°C accuracy must use AD590MH.

Q: Are the package specifications identical between AD590MH and AD590JH?

A: Yes. Both parts use TO-206AC and TO-52-3 Metal Can packages with Through Hole mounting type, ensuring mechanical and electrical compatibility at the board level.

Q: What is the difference between Box and Bulk packaging?

A: Box packaging provides individual component protection and controlled quantities suitable for smaller production runs. Bulk packaging offers higher unit quantities per container, optimizing cost per unit for large-volume manufacturing operations. Electrical and mechanical specifications remain identical regardless of packaging format.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both AD590MH and AD590JH are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component manufacturing and distribution.

Q: What supply voltage range is required for both sensors?

A: Both AD590MH and AD590JH require a supply voltage between 4V and 30V, enabling compatibility with standard industrial power supply configurations.
