Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AD024-00E is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Omnipolar switch function (detection of both north and south magnetic poles)
• Surface mount package format (8-MSOP)
• Operating temperature range: -40°C ~ 125°C
• Supply voltage range: 4.5V ~ 30V
• Output configuration compatible with open collector or digital output applications
• RoHS3 compliance and REACH unaffected status

Allowable Parameter Variations:

• Sensing range thresholds (trip and release points) may differ within application tolerance
• Supply current and output current specifications may vary provided they remain within system design limits
• Technology implementation (Hall Effect vs. Magnetoresistive) is permissible if functional output characteristics remain compatible

The AD024-00E-TR qualifies as a direct substitute based on matching core functional requirements, identical package specifications, and compatible electrical operating parameters.

Engineering Selection Recommendations

Primary Substitute: AD024-00E-TR

The AD024-00E-TR is the direct substitute for the discontinued AD024-00E. Both components are manufactured by NVE Corp/Sensor Products and share identical core specifications including supply voltage range (4.5V ~ 30V), operating temperature range (-40°C ~ 125°C), package format (8-MSOP), and omnipolar switch functionality.

Key Considerations for Selection:

1. Product Status: The AD024-00E is discontinued; the AD024-00E-TR maintains active product status with confirmed inventory availability (5610 pcs in stock).

2. Packaging Format: The AD024-00E-TR is supplied in tape & reel (TR) format, standard for production environments. If bulk packaging is required, consult with NVE Corp/Sensor Products for alternative packaging options.

3. Compliance Certification: Both components maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for electronic component deployment.

4. Electrical Parameter Variations: The AD024-00E-TR exhibits higher maximum supply current (6.5mA vs. 4.5mA) and output current (24mA vs. 20mA). These increases are within typical system design margins and do not preclude substitution.

5. Sensing Range Differences: The AD024-00E-TR demonstrates different trip and release thresholds (3.3mT trip, 0.5mT release vs. ±3.4mT trip, ±1.4mT release). Application-specific validation is required to confirm compatibility with magnetic field detection requirements.

6. Technology Implementation: The AD024-00E-TR utilizes magnetoresistive technology versus the Hall Effect technology of the AD024-00E. Both technologies deliver compatible digital switch output suitable for the same circuit applications.

7. Output Configuration: The AD024-00E-TR provides digital output versus open collector output on the AD024-00E. Circuit interface verification is necessary to confirm compatibility with existing pull-up resistor configurations and signal conditioning circuits.

Frequently Asked Questions (FAQ)

Q: Can the AD024-00E-TR directly replace the AD024-00E without circuit modifications?

A: The AD024-00E-TR is functionally equivalent for omnipolar magnetic switch applications. However, the output type differs (digital vs. open collector). Verify that your circuit's pull-up resistor configuration and signal conditioning are compatible with digital output logic levels. Sensing range thresholds also differ; confirm that your application tolerates the specified trip (3.3mT) and release (0.5mT) points.

Q: What is the difference between Hall Effect and Magnetoresistive technology in these components?

A: Both technologies detect magnetic field presence and generate digital switch output. Hall Effect (AD024-00E) and Magnetoresistive (AD024-00E-TR) implementations differ in internal sensing mechanism but deliver equivalent functional performance for omnipolar switch applications. Selection between technologies is determined by application-specific magnetic field characteristics and environmental factors.

Q: Are there packaging options other than tape & reel for the AD024-00E-TR?

A: The AD024-00E-TR is specified in tape & reel (TR) format. Contact NVE Corp/Sensor Products directly to inquire about alternative packaging configurations if bulk or custom packaging is required for your production process.

Q: How do the sensing range specifications differ between AD024-00E and AD024-00E-TR?

A: The AD024-00E specifies ±3.4mT trip threshold and ±1.4mT release threshold. The AD024-00E-TR specifies 3.3mT trip threshold and 0.5mT release threshold. These variations reflect different sensor implementations. Validate that your application's magnetic field strength and hysteresis requirements are compatible with the AD024-00E-TR specifications.

Q: What is the significance of the 8-MSOP package specification?

A: The 8-MSOP (8-pin Miniature Small Outline Package) with 0.118" width and 3.00mm body width is a standard surface mount package. Both the AD024-00E and AD024-00E-TR utilize identical package dimensions, ensuring PCB footprint and reflow soldering process compatibility.

Q: Are both components RoHS3 compliant?

A: Yes. Both the AD024-00E and AD024-00E-TR are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for electronic component use in regulated markets.

Q: What is the MSL (Moisture Sensitivity Level) rating, and why is it important?

A: Both components carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions. Components may be stored at standard ambient conditions without desiccant packaging or time-limited shelf life constraints, simplifying inventory management and supply chain logistics.
