AA003-02 Magnetoresistive Sensor Equivalent & Substitute Parts

Part Overview

The AA003-02 is a magnetoresistive sensor manufactured by NVE Corp/Sensor Products, designed as a single-axis Wheatstone bridge output magnetic sensor in an 8-SOIC surface mount package. This component is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and procurement continuity. The sensor operates across a sensing range of 0.2mT to 1.4mT with supply voltage flexibility from 1V to 24V and temperature compensation features suitable for industrial applications spanning -50°C to 125°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AA003-02 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Technology: Magnetoresistive
• Axis Configuration: Single
• Output Type: Wheatstone Bridge
• Sensing Range: 0.2mT ~ 1.4mT
• Voltage - Supply: 1V ~ 24V
• Operating Temperature: -50°C ~ 125°C (TA)
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Features: Temperature Compensated

The AA003-02E qualifies as a direct substitute based on complete alignment with all mandatory parameters. The primary distinction is product status transition from obsolete to active, coupled with packaging format change from unspecified to tube packaging and improved RoHS compliance status.

Engineering Selection Recommendations

The AA003-02E is the direct functional equivalent of the AA003-02 magnetoresistive sensor. Selection of AA003-02E is supported by the following engineering factors:

Product Status: The AA003-02E maintains active product status, ensuring continued manufacturer support, availability, and technical documentation access. The AA003-02 is classified as obsolete, creating long-term supply chain risk.

Regulatory Compliance: The AA003-02E achieves ROHS3 compliance, whereas the AA003-02 is RoHS non-compliant. For applications subject to RoHS directives or customer compliance requirements, AA003-02E satisfies regulatory obligations.

Electrical and Mechanical Equivalence: All functional parameters—sensing range, supply voltage, operating temperature, output configuration, and package dimensions—are identical between the two parts. Pin-to-pin compatibility and circuit-level integration are preserved.

Packaging: AA003-02E is supplied in tube packaging, a standard format for automated assembly and inventory management, compared to the unspecified packaging of AA003-02.

Frequently Asked Questions (FAQ)

Q: Can AA003-02E be used as a direct replacement for AA003-02 in existing designs?

A: Yes. The AA003-02E is electrically and mechanically equivalent to AA003-02. All functional parameters, including sensing range (0.2mT ~ 1.4mT), supply voltage (1V ~ 24V), operating temperature (-50°C ~ 125°C), output type (Wheatstone Bridge), and 8-SOIC package dimensions are identical. No circuit modifications are required.

Q: What is the primary reason to transition from AA003-02 to AA003-02E?

A: The AA003-02 is obsolete, creating procurement and support discontinuity. The AA003-02E is an active product with ongoing manufacturer support. Additionally, AA003-02E achieves ROHS3 compliance, addressing regulatory requirements not met by the AA003-02.

Q: Are the pin configurations identical between AA003-02 and AA003-02E?

A: Yes. Both parts use the 8-SOIC package with identical pin assignments. PCB layouts and connector designs require no modification.

Q: Does packaging format affect electrical performance?

A: No. The tube packaging of AA003-02E is a handling and logistics format. Electrical specifications, performance characteristics, and functional behavior are unaffected by packaging format.

Q: Is the AA003-02E suitable for temperature-compensated applications?

A: Yes. The AA003-02E includes temperature compensation features identical to the AA003-02, maintaining sensor accuracy across the -50°C to 125°C operating range.

Q: What is the sensing range of the AA003-02E?

A: The sensing range is 0.2mT to 1.4mT, identical to the AA003-02. This range is suitable for applications requiring detection of magnetic fields within this specification.
