AD104-00 Omnipolar Hall Effect Magnetic Switch - Equivalent & Substitute Parts

Part Overview

The AD104-00 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 device operates across a wide supply voltage range of 4.5V to 30V with a maximum supply current of 4.5mA and output current capability of 20mA. The AD104-00 is classified as obsolete, making identification of active equivalent parts essential for new designs and ongoing production requirements. The substitute part AD104-00E provides functional continuity with improved compliance status.

Substitute Part Grouping Explanation

Substitution of the AD104-00 with the AD104-00E is based on strict electrical and mechanical parameter equivalence. Both parts maintain identical specifications across all critical functional parameters:

Electrical Equivalence Criteria:

• Hall effect omnipolar switching technology
• Identical sensing range thresholds (±2.5mT trip, ±1.1mT release)
• Matching supply voltage range (4.5V ~ 30V)
• Identical supply current specification (4.5mA maximum)
• Matching output current capability (20mA maximum)
• Open collector output configuration
• Identical operating temperature range (-40°C ~ 125°C)

Mechanical Equivalence Criteria:

• Surface mount technology
• 8-MSOP package configuration
• 8-TSSOP package compatibility
• 0.118" width, 3.00mm standard dimensions

The AD104-00E differs from the AD104-00 only in product status (Active versus Obsolete) and compliance certifications (RoHS3 Compliant versus RoHS non-compliant), with no functional or electrical parameter variations.

Parameter Comparison

Engineering Selection Recommendations

The AD104-00E is the direct functional equivalent of the AD104-00 with complete electrical and mechanical parameter alignment. Selection between these parts should be based on the following criteria:

For New Designs and Production: Use AD104-00E. This part carries Active product status, ensuring long-term availability and supply chain continuity. The RoHS3 compliance certification meets current environmental and regulatory requirements for electronic components in most jurisdictions.

For Legacy System Maintenance: The AD104-00 remains functionally equivalent to AD104-00E. However, sourcing of the obsolete AD104-00 is subject to inventory availability constraints. Transition to AD104-00E is recommended to eliminate supply risk.

Compliance Considerations: The AD104-00E meets RoHS3 compliance standards, while the AD104-00 does not. Both parts maintain REACH Unaffected status and EAR99 export classification. Organizations subject to RoHS compliance mandates should prioritize AD104-00E for all new applications.

Packaging and Inventory: AD104-00E is supplied in Tube packaging with 709 pieces currently in stock. The AD104-00 is available in 676 pieces but carries obsolete status. Packaging format differences do not affect functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can AD104-00E be used as a direct replacement for AD104-00 in existing designs?

A: Yes. The AD104-00E provides complete functional equivalence with identical electrical specifications, sensing thresholds, supply voltage range, output current capability, operating temperature range, and surface mount package configuration. No circuit modifications are required.

Q: What is the primary difference between AD104-00 and AD104-00E?

A: The AD104-00E is the active production equivalent of the obsolete AD104-00. Both parts are electrically and mechanically identical. The AD104-00E carries RoHS3 compliance certification, while the AD104-00 does not. The AD104-00E is supplied in Tube packaging.

Q: Are there any package compatibility issues when substituting AD104-00 with AD104-00E?

A: No. Both parts use the 8-MSOP surface mount package with identical 0.118" width and 3.00mm standard dimensions. PCB footprints and assembly processes remain unchanged.

Q: Does the AD104-00E maintain the same sensing range specifications?

A: Yes. The AD104-00E maintains identical trip threshold (±2.5mT) and release threshold (±1.1mT) specifications. Omnipolar detection of north and south magnetic poles is unchanged.

Q: What is the supply voltage compatibility range for both parts?

A: Both AD104-00 and AD104-00E operate across 4.5V to 30V supply voltage range with maximum supply current of 4.5mA and maximum output current of 20mA.

Q: Is RoHS compliance a factor in selecting between these parts?

A: RoHS compliance becomes a factor only if your application or regulatory jurisdiction mandates it. The AD104-00E meets RoHS3 requirements, while the AD104-00 does not. For new designs and production, AD104-00E is the recommended choice.

Q: What is the operating temperature range for these components?

A: Both parts operate across -40°C to 125°C ambient temperature range, suitable for industrial and automotive applications.

Q: Are there any differences in output configuration between these parts?

A: No. Both parts feature open collector output configuration with identical 20mA maximum output current capability.
