AA004-00 Magnetoresistive Sensor Equivalent & Substitute Parts

Part Overview

The AA004-00 is a magnetoresistive sensor manufactured by NVE Corp/Sensor Products, designed as a single-axis Wheatstone bridge output magnetic sensor in an 8-MSOP surface mount package. This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support, maintenance, and production continuity. The sensor operates across a wide supply voltage range (1V to 24V) with temperature compensation and is suitable for applications requiring magnetic field detection in the 0.5mT to 3.5mT sensing range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AA004-00 is determined by strict equivalence across the following critical parameters:

Technology & Functional Parameters:

• Magnetoresistive technology (required for signal conditioning and output characteristics)
• Single-axis configuration (determines sensing capability)
• Wheatstone bridge output topology (defines signal processing compatibility)
• Sensing range 0.5mT ~ 3.5mT (establishes magnetic field detection capability)

Electrical Parameters:

• Supply voltage range 1V ~ 24V (ensures power supply compatibility)
• Operating temperature range -50°C ~ 125°C (defines thermal operating envelope)
• Temperature compensation feature (maintains performance stability)

Mechanical & Packaging Parameters:

• 8-MSOP package / 8-TSSOP case (0.118", 3.00mm Width) (ensures PCB footprint and assembly compatibility)
• Surface mount mounting type (defines assembly process compatibility)

Compliance Parameters:

• Moisture Sensitivity Level 1 (Unlimited) (establishes storage and handling requirements)

Substitute parts must match all parameters listed above. Variations in RoHS compliance or product status do not disqualify substitution when all functional and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

AA004-00E and AA004-00ETR are direct functional equivalents to the AA004-00. Both substitute parts maintain identical magnetoresistive sensor specifications, single-axis configuration, Wheatstone bridge output topology, sensing range, supply voltage range, operating temperature range, and temperature compensation features. Package and mounting specifications are identical, ensuring PCB footprint compatibility without design modification.

Compliance Consideration: The substitute parts AA004-00E and AA004-00ETR are ROHS3 compliant, whereas the main part AA004-00 is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the substitute parts provide compliance alignment. For legacy systems or applications without RoHS mandates, both compliant and non-compliant variants are functionally interchangeable.

Product Status: The main part AA004-00 is classified as obsolete. The substitute parts AA004-00E and AA004-00ETR are discontinued at DiGi Electronics but remain available through alternative distribution channels. Selection between these variants should be based on supply chain availability and regulatory compliance requirements specific to the application.

Frequently Asked Questions (FAQ)

Q: Can AA004-00E or AA004-00ETR be used as direct replacements for AA004-00 without circuit modification?

A: Yes. Both substitute parts are functionally equivalent across all critical parameters: magnetoresistive technology, single-axis configuration, Wheatstone bridge output, 0.5mT to 3.5mT sensing range, 1V to 24V supply voltage, -50°C to 125°C operating temperature, temperature compensation, and 8-MSOP package. No circuit modification is required.

Q: What is the difference between AA004-00E and AA004-00ETR?

A: Both parts are manufactured by NVE Corp/Sensor Products and share identical functional and mechanical specifications. The designation suffix "TR" typically indicates tape-and-reel packaging format, whereas "E" indicates standard packaging. Electrical and performance characteristics are equivalent.

Q: Does the RoHS compliance difference between AA004-00 and its substitutes affect compatibility?

A: RoHS compliance status does not affect electrical or mechanical compatibility. The difference reflects manufacturing process and material composition changes. For applications subject to RoHS regulations (EU Directive 2011/65/EU or equivalent), the ROHS3-compliant substitutes AA004-00E and AA004-00ETR are required. For applications without RoHS mandates, both compliant and non-compliant variants are functionally interchangeable.

Q: Are there any parameter differences that would prevent substitution?

A: No. All parameters that determine substitution eligibility—technology, axis configuration, output type, sensing range, supply voltage, operating temperature, features, package, and mounting type—are identical across the main part and substitute parts.

Q: What is the Moisture Sensitivity Level (MSL) significance for these parts?

A: MSL 1 (Unlimited) indicates these components have unlimited shelf life under standard storage conditions and do not require special moisture control during storage or handling. This applies uniformly to AA004-00, AA004-00E, and AA004-00ETR.
