AAH002-02 Equivalent & Substitute Parts

Part Overview

The AAH002-02 is a magnetoresistive sensor featuring a Wheatstone bridge output configuration in an 8-SOIC surface mount package. This single-axis magnetic sensor is designed for applications requiring detection within the 0.06mT to 0.3mT sensing range with temperature compensation across the -50°C to 150°C operating window. The part is manufactured by NVE Corp/Sensor Products and operates across a 1V to 12V supply voltage range.

The AAH002-02 carries an obsolete product status, making identification of equivalent substitutes necessary for ongoing design support, maintenance, and new production requirements. Substitute parts must maintain identical electrical performance characteristics, mechanical compatibility, and functional output specifications to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AAH002-02 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Technology: Magnetoresistive
• Axis Configuration: Single
• Output Type: Wheatstone Bridge
• Sensing Range: 0.06mT ~ 0.3mT
• Supply Voltage Range: 1V ~ 12V
• Operating Temperature Range: -50°C ~ 150°C (TA)
• Package Type: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Temperature Compensation: Required

The AAH002-02E qualifies as a direct substitute based on complete parameter alignment across all electrical and mechanical specifications. The primary distinction between the main part and its substitute relates to product status classification and packaging format, with the substitute offering active product status and improved regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The AAH002-02E serves as the direct functional equivalent to the obsolete AAH002-02 magnetoresistive sensor. Selection of the AAH002-02E is supported by the following engineering considerations:

Product Status: The AAH002-02E maintains active product status, ensuring continued availability and manufacturer support. The AAH002-02 is classified as obsolete, limiting future procurement options and technical resources.

Regulatory Compliance: The AAH002-02E achieves ROHS3 compliance, meeting current environmental and hazardous substance restrictions. The AAH002-02 is non-compliant with RoHS requirements, presenting potential regulatory constraints for new designs and applications subject to RoHS directives.

Electrical and Mechanical Equivalence: All critical parameters—including magnetoresistive technology, single-axis configuration, Wheatstone bridge output, 0.06mT to 0.3mT sensing range, 1V to 12V supply voltage, -50°C to 150°C operating temperature, and 8-SOIC surface mount package—are identical between both parts.

Packaging Availability: The AAH002-02E is supplied in tube packaging format, providing standard handling and storage compatibility with modern component management systems.

Frequently Asked Questions (FAQ)

Q: Can the AAH002-02E be used as a direct replacement for the AAH002-02 in existing designs?

A: Yes. The AAH002-02E is electrically and mechanically equivalent to the AAH002-02 across all specified parameters. Both parts feature identical magnetoresistive technology, Wheatstone bridge output, sensing range, supply voltage, operating temperature, and 8-SOIC package configuration. Direct substitution is supported without circuit modification.

Q: What is the primary difference between the AAH002-02 and AAH002-02E?

A: The primary differences are product status and regulatory compliance. The AAH002-02 is obsolete and RoHS non-compliant, while the AAH002-02E is active and ROHS3 compliant. The AAH002-02E is supplied in tube packaging. All electrical and mechanical specifications remain identical.

Q: Are there any compatibility concerns with the 8-SOIC package between these parts?

A: No. Both parts use the identical 8-SOIC package configuration with 0.154" (3.90mm) width. PCB footprints, solder pad layouts, and mounting procedures are fully compatible.

Q: Does the AAH002-02E maintain the same temperature compensation feature?

A: Yes. The AAH002-02E includes temperature compensation across the full -50°C to 150°C operating range, identical to the AAH002-02.

Q: What is the sensing range for both parts?

A: Both the AAH002-02 and AAH002-02E operate within a 0.06mT to 0.3mT sensing range with identical sensitivity characteristics.

Q: Are there any supply voltage differences between these parts?

A: No. Both parts operate across the identical 1V to 12V supply voltage range, providing equivalent flexibility for various power supply configurations.

Q: Why should the AAH002-02E be selected for new designs?

A: The AAH002-02E should be selected for new designs due to its active product status, ROHS3 compliance, and continued manufacturer support. The AAH002-02 is obsolete and presents long-term availability and regulatory risks.
