AAL002-02 Magnetoresistive Sensor Equivalent & Substitute Parts

Part Overview

The AAL002-02 is a magnetoresistive sensor featuring a Wheatstone bridge output configuration, manufactured by NVE Corp/Sensor Products. This single-axis magnetic sensor is designed for applications requiring detection of magnetic fields within the 0.15mT to 1.05mT sensing range. The device operates across a wide supply voltage range of 1V to 25V and maintains temperature compensation across the -50°C to 150°C operating window.

The AAL002-02 carries an obsolete product status. Locating equivalent substitute parts is necessary to ensure continued availability for new designs, production continuity, and long-term system support. The substitute part identified maintains identical electrical and mechanical specifications while offering active product status and improved compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AAL002-02 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Magnetoresistive technology platform
• Single-axis sensing configuration
• Wheatstone bridge output topology
• Identical sensing range: 0.15mT ~ 1.05mT
• Matching supply voltage range: 1V ~ 25V
• Equivalent operating temperature range: -50°C ~ 150°C

Mechanical Equivalence Criteria:

• 8-SOIC package format with 0.154" (3.90mm) width
• Surface mount mounting type
• Temperature compensation feature

The AAL002-02E qualifies as a direct substitute based on complete alignment with all electrical and mechanical parameters listed above. The primary distinction between the main part and substitute is product status and packaging format, with the substitute offering active availability and enhanced regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Production Continuity:

The AAL002-02E is the appropriate selection for applications currently specified with the AAL002-02. The substitute part maintains complete electrical and mechanical compatibility while offering the advantage of active product status, ensuring long-term availability and supply chain stability.

Compliance Considerations:

The AAL002-02E provides ROHS3 compliance, whereas the original AAL002-02 is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements mandating RoHS compliance, the AAL002-02E satisfies these regulatory requirements without modification to circuit design or board layout.

Packaging and Logistics:

The AAL002-02E is supplied in tube packaging, compared to bulk packaging for the AAL002-02. This difference affects component handling and automated assembly processes but does not impact electrical or mechanical performance. Tube packaging is standard for active production components and supports standard pick-and-place assembly equipment.

Supply Chain Status:

With 1098 pieces in current inventory and active product status, the AAL002-02E provides reliable long-term availability. The obsolete status of the AAL002-02 indicates limited remaining stock and no future manufacturing, making transition to the AAL002-02E necessary for sustained production.

Frequently Asked Questions (FAQ)

Q: Can the AAL002-02E be used as a direct replacement for the AAL002-02 in existing designs?

A: Yes. The AAL002-02E is electrically and mechanically identical to the AAL002-02 across all specified parameters. No circuit modifications, PCB layout changes, or firmware adjustments are required. The substitute part operates within identical voltage ranges, temperature ranges, and sensing specifications.

Q: What is the difference between the AAL002-02 and AAL002-02E?

A: The primary differences are product status and packaging format. The AAL002-02E is an active product with current manufacturing support, while the AAL002-02 is obsolete. The AAL002-02E is supplied in tube packaging for automated assembly, whereas the AAL002-02 was supplied in bulk format. The AAL002-02E also provides ROHS3 compliance compared to the non-compliant AAL002-02.

Q: Are there any performance differences between these parts?

A: No. Both parts utilize identical magnetoresistive technology, feature the same Wheatstone bridge output configuration, and operate across the same sensing range (0.15mT ~ 1.05mT), supply voltage range (1V ~ 25V), and temperature range (-50°C ~ 150°C). Temperature compensation is present in both versions.

Q: What is the 8-SOIC package specification?

A: The 8-SOIC package is a surface-mount integrated circuit package with 8 pins, measuring 0.154 inches (3.90mm) in width. This package format is standard for small-signal analog sensors and is compatible with standard PCB assembly equipment and design practices.

Q: Why is the AAL002-02 listed as obsolete?

A: Obsolete status indicates that the manufacturer has discontinued production and will not manufacture additional units. Existing inventory may be available from distributors, but supply is limited and will eventually be exhausted. The AAL002-02E represents the active replacement product line.

Q: Is the tube packaging compatible with my assembly process?

A: Tube packaging is the standard format for active production components and is compatible with automated pick-and-place assembly equipment used in modern PCB manufacturing. If your assembly process requires bulk packaging, contact your distributor regarding packaging options or consider reel packaging alternatives if available.

Q: What certifications apply to the AAL002-02E?

A: The AAL002-02E is ROHS3 compliant and REACH unaffected. Both the original AAL002-02 and substitute AAL002-02E share the same ECCN (EAR99) and HTSUS (8542.39.0001) classifications. Moisture sensitivity level is MSL 1 (Unlimited) for both parts.

Q: Can I mix AAL002-02 and AAL002-02E components in the same production batch?

A: Yes. Since the parts are electrically and mechanically identical, they can be used interchangeably in the same circuit and PCB design. However, for traceability and supply chain management, it is recommended to standardize on the AAL002-02E for all new production to ensure consistent availability and compliance status.
