AAH004-00 Magnetoresistive Sensor Equivalent & Substitute Parts

Part Overview

The AAH004-00 is a magnetoresistive sensor manufactured by NVE Corp/Sensor Products, designed as a single-axis Wheatstone bridge output device in an 8-MSOP 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 0.15mT to 0.75mT with supply voltage flexibility from 1V to 12V and includes temperature compensation across an operating range of -50°C to 150°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AAH004-00 is determined by strict equivalence across the following critical parameters:

• Technology: Magnetoresistive
• Axis Configuration: Single axis
• Output Type: Wheatstone Bridge
• Sensing Range: 0.15mT ~ 0.75mT
• Supply Voltage Range: 1V ~ 12V
• Operating Temperature Range: -50°C ~ 150°C
• Package Type: 8-MSOP surface mount
• Physical Dimensions: 8-TSSOP, 8-MSOP (0.118", 3.00mm Width)
• Features: Temperature Compensated

The AAH004-00E qualifies as a direct substitute based on complete alignment with all specified electrical and mechanical parameters. The primary distinction between the main part and its substitute relates to product status and regulatory compliance, not functional performance.

Parameter Comparison

Engineering Selection Recommendations

The AAH004-00E serves as the direct functional equivalent to the obsolete AAH004-00 magnetoresistive sensor. Selection between these parts is determined by regulatory and procurement requirements rather than electrical or mechanical performance differences.

For applications requiring RoHS3 compliance: The AAH004-00E is the appropriate selection, as it meets ROHS3 compliance standards while the AAH004-00 is RoHS non-compliant.

For applications with no RoHS compliance mandate: Either part satisfies the functional requirements, provided supply chain availability is confirmed.

For new designs: The AAH004-00E is the preferred choice due to its active product status, ensuring long-term availability and manufacturing support.

Both parts maintain identical REACH status (REACH Unaffected), ECCN classification (EAR99), and HTSUS code (8542.39.0001). Moisture sensitivity level is equivalent at MSL 1 (Unlimited) for both variants.

Frequently Asked Questions (FAQ)

Q: Can the AAH004-00E be used as a direct replacement for the AAH004-00 in existing designs?

A: Yes. The AAH004-00E is electrically and mechanically identical to the AAH004-00 across all functional parameters: sensing range, supply voltage, operating temperature, output type, and package configuration. Pin-to-pin compatibility is maintained.

Q: What is the primary reason to transition from AAH004-00 to AAH004-00E?

A: The AAH004-00 is classified as obsolete, while the AAH004-00E maintains active product status. This ensures continued manufacturing availability, supply chain stability, and long-term procurement viability. Additionally, the AAH004-00E achieves ROHS3 compliance, whereas the AAH004-00 does not.

Q: Are there differences in the Wheatstone bridge output characteristics between these parts?

A: No. Both the AAH004-00 and AAH004-00E employ identical Wheatstone bridge output architecture with temperature compensation across the -50°C to 150°C operating range.

Q: Does packaging differ between the two parts?

A: The AAH004-00E is supplied in tube packaging, while the AAH004-00 packaging specification is not provided. Both use the same 8-MSOP surface mount package with 0.118" (3.00mm) width. Verify packaging requirements for your specific assembly process.

Q: Are both parts suitable for the 0.15mT to 0.75mT sensing range application?

A: Yes. Both parts are specified for identical sensing range operation from 0.15mT to 0.75mT and support the same 1V to 12V supply voltage range.

Q: What is the moisture sensitivity level for these sensors?

A: Both the AAH004-00 and AAH004-00E are rated at MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
