AA004-02 Magnetoresistive Sensor Equivalent & Substitute Parts

Part Overview

The AA004-02 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 active equivalent parts for ongoing design support and procurement continuity. The sensor operates across a sensing range of 0.5mT to 3.5mT 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 of the AA004-02 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Technology: Magnetoresistive
• Axis Configuration: Single
• Output Type: Wheatstone Bridge
• Sensing Range: 0.5mT ~ 3.5mT
• 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 AA004-02E qualifies as a direct substitute based on identical electrical specifications, mechanical packaging, and functional characteristics. The primary distinction is product status transition from obsolete to active, with improved regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The AA004-02E is the direct functional equivalent of the AA004-02 magnetoresistive sensor. Selection of AA004-02E is supported by the following engineering factors:

Product Status: The AA004-02E maintains active product status with ongoing manufacturer support, whereas the AA004-02 is classified as obsolete. This transition ensures long-term availability and supply chain continuity.

Regulatory Compliance: The AA004-02E achieves ROHS3 compliance, addressing modern regulatory requirements for electronic components. The original AA004-02 is RoHS non-compliant, which may present procurement restrictions in regulated markets.

Electrical and Mechanical Equivalence: All critical parameters—sensing range, supply voltage, operating temperature, output configuration, and package dimensions—are identical between the two parts. Pin-for-pin compatibility is maintained.

Certification Status: Both parts maintain identical REACH Unaffected and EAR99 ECCN classifications, ensuring no change in export or import regulatory treatment.

For applications currently using AA004-02, direct substitution with AA004-02E requires no circuit redesign, PCB layout modification, or firmware adjustment.

Frequently Asked Questions (FAQ)

Q: Is AA004-02E a pin-for-pin replacement for AA004-02?

A: Yes. Both components use the 8-SOIC package with identical pin configuration and electrical interface. No PCB layout changes are required.

Q: What is the primary reason to transition from AA004-02 to AA004-02E?

A: The AA004-02 is obsolete with no ongoing manufacturer support. The AA004-02E is an active product with identical electrical specifications and improved regulatory compliance (ROHS3).

Q: Are the sensing characteristics identical between AA004-02 and AA004-02E?

A: Yes. Both sensors operate across the same 0.5mT to 3.5mT sensing range, support 1V to 24V supply voltage, include temperature compensation, and function across -50°C to 125°C operating temperature.

Q: Does the packaging format differ between these parts?

A: The AA004-02E is supplied in Tube packaging, whereas the AA004-02 packaging format is not specified in available documentation. Both use the same 8-SOIC physical package for PCB mounting.

Q: What compliance advantage does AA004-02E provide?

A: The AA004-02E is ROHS3 compliant, meeting current environmental and hazardous substance restrictions. The AA004-02 is RoHS non-compliant, which may restrict use in certain regulated applications and markets.

Q: Can AA004-02 and AA004-02E be used interchangeably in existing designs?

A: Yes. Identical electrical specifications, output characteristics, and physical packaging enable direct substitution without circuit modification or performance impact.
