AD004-00 Omnipolar Hall Effect Magnetic Switch Equivalent & Substitute Parts

Part Overview

The AD004-00 is a digital omnipolar Hall effect magnetic switch manufactured by NVE Corp/Sensor Products. This component functions as an open collector switch, detecting both north and south magnetic poles within a ±2.5mT trip threshold and ±1.1mT release threshold. The AD004-00 is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity. The substitute part AD004-00E provides functional and electrical equivalence while maintaining active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD004-00 with the AD004-00E is based on strict electrical and mechanical parameter equivalence. Both parts share identical specifications across all critical functional parameters:

Key Substitution Criteria:

• Hall effect omnipolar switching technology with identical polarization (North Pole, South Pole detection)
• Identical sensing thresholds: ±2.5mT trip and ±1.1mT release
• Identical supply voltage range: 4.5V to 30V
• Identical maximum supply current: 4.5mA
• Identical maximum output current: 20mA
• Identical open collector output configuration
• Identical operating temperature range: -40°C to 125°C
• Identical surface mount package: 8-MSOP with 0.118" (3.00mm) width
• Identical pinout and electrical interface

The primary distinction between these parts is product status and regulatory compliance, not electrical or mechanical function.

Engineering Selection Recommendations

For New Designs and Procurement: The AD004-00E is the appropriate selection for all applications requiring an omnipolar Hall effect magnetic switch with the specified electrical and mechanical parameters. This part maintains active product status with NVE Corp/Sensor Products, ensuring long-term availability and supply chain stability.

For Regulatory Compliance: The AD004-00E carries ROHS3 compliance certification, meeting current environmental and hazardous substance restrictions. The original AD004-00 is RoHS non-compliant and should not be selected for applications subject to RoHS directives or equivalent regulatory frameworks.

For Existing Designs Using AD004-00: Direct substitution with AD004-00E is electrically and mechanically valid. No circuit modifications, PCB layout changes, or firmware adjustments are required. The identical electrical interface, pinout, and performance characteristics ensure drop-in compatibility.

Packaging Consideration: The AD004-00E is supplied in tube packaging, which is standard for active production components. Original AD004-00 packaging specifications were not provided in available documentation.

Frequently Asked Questions (FAQ)

Q: Can AD004-00E directly replace AD004-00 in existing circuit designs?

A: Yes. The AD004-00E provides complete electrical and mechanical equivalence to the AD004-00. Identical supply voltage range (4.5V to 30V), output current capability (20mA maximum), sensing thresholds (±2.5mT trip, ±1.1mT release), operating temperature range (-40°C to 125°C), and 8-MSOP surface mount package ensure direct substitution without circuit modifications.

Q: What is the primary reason to transition from AD004-00 to AD004-00E?

A: The AD004-00 is classified as obsolete, creating procurement and long-term supply risks. The AD004-00E maintains active product status with NVE Corp/Sensor Products, providing reliable availability. Additionally, AD004-00E carries ROHS3 compliance certification, while the original AD004-00 is RoHS non-compliant.

Q: Are the pinout and PCB footprints identical between these parts?

A: Yes. Both parts use the 8-MSOP package with identical dimensions (0.118" or 3.00mm width). PCB footprints, land patterns, and pinout configurations are identical, requiring no layout modifications.

Q: What are the critical sensing parameters that define substitution eligibility?

A: Substitution is valid only when the following parameters match: Hall effect omnipolar technology, ±2.5mT trip threshold, ±1.1mT release threshold, and North Pole/South Pole polarization detection. The AD004-00E meets all these criteria.

Q: Does the AD004-00E have different electrical performance characteristics?

A: No. The AD004-00E maintains identical electrical specifications: 4.5V to 30V supply voltage, 4.5mA maximum supply current, 20mA maximum output current, open collector output configuration, and -40°C to 125°C operating temperature range.

Q: Is RoHS compliance a functional requirement or a regulatory requirement?

A: RoHS compliance is a regulatory requirement determined by application jurisdiction and customer specifications. The AD004-00E provides ROHS3 compliance for applications subject to these restrictions. The non-compliant AD004-00 may not be acceptable for regulated markets or customers with mandatory RoHS requirements.
