AA002-02 Magnetoresistive Sensor Equivalent & Substitute Parts

Part Overview

The AA002-02 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 equivalent substitute parts for ongoing design support and procurement continuity. The sensor operates across a sensing range of 0.15mT to 1.05mT with supply voltage flexibility from 1V to 24V and temperature compensation features for stable operation between -50°C and 125°C.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AA002-02 are identified based on strict electrical and mechanical parameter alignment. The substitution criteria are:

Primary Substitution Parameters:

• Technology: Magnetoresistive
• Axis Configuration: Single
• Output Type: Wheatstone Bridge
• Sensing Range: 0.15mT ~ 1.05mT
• 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 AA002-02E is identified as a direct substitute. This part maintains identical electrical specifications and mechanical packaging while offering improved product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The AA002-02E is the direct substitute for the AA002-02. Selection between these parts is determined by regulatory and procurement requirements:

AA002-02E Selection Criteria:

• Required for new designs and applications requiring ROHS3 compliance
• Recommended for long-term production continuity due to active product status
• Suitable for applications with REACH compliance requirements
• Preferred for supply chain stability with higher inventory availability (4957 Pcs vs. 1096 Pcs)

AA002-02 Retention Criteria:

• Existing designs with established qualification and validation
• Applications where RoHS non-compliance is not a constraint
• Immediate availability requirements from existing stock

Both parts are electrically and mechanically identical, with identical sensing range, supply voltage, operating temperature, and package specifications. The distinction is product lifecycle status and regulatory compliance posture.

Frequently Asked Questions (FAQ)

Q: Can AA002-02E directly replace AA002-02 in existing designs?

A: Yes. The AA002-02E maintains identical electrical specifications (sensing range 0.15mT ~ 1.05mT, supply voltage 1V ~ 24V, operating temperature -50°C ~ 125°C) and mechanical packaging (8-SOIC, 0.154" width, surface mount). No circuit modifications are required.

Q: What is the primary difference between AA002-02 and AA002-02E?

A: The AA002-02E is ROHS3 compliant and carries active product status, while the AA002-02 is obsolete and RoHS non-compliant. Both parts are functionally equivalent magnetoresistive sensors with Wheatstone bridge output and temperature compensation.

Q: Are there packaging differences between these parts?

A: Both parts use identical 8-SOIC (0.154", 3.90mm Width) surface mount packages. The AA002-02E is supplied in tube packaging, while the AA002-02 packaging specification is not detailed in available documentation.

Q: Which part should be selected for new product development?

A: The AA002-02E is the appropriate selection for new designs. It offers active product status, ROHS3 compliance, and superior inventory availability, ensuring long-term design support and regulatory alignment.

Q: Are the sensing range and temperature compensation identical?

A: Yes. Both parts operate across 0.15mT ~ 1.05mT sensing range with temperature compensation features and identical -50°C ~ 125°C operating temperature range.
