AD122-00 Equivalent & Substitute Parts Reference

Part Overview

The AD122-00 is an omnipolar Hall Effect magnetic switch manufactured by NVE Corp/Sensor Products, designed for digital switching applications with open collector output. This component operates across a wide supply voltage range (4.5V to 30V) and detects magnetic fields from both north and south poles with a trip threshold of ±5mT and release threshold of ±2.5mT.

The AD122-00 carries an obsolete product status. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term production requirements for applications currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AD122-00 is determined by strict equivalence across the following critical parameters:

Functional Equivalence: The substitute part must perform omnipolar Hall Effect switching with identical trip and release thresholds (±5mT trip, ±2.5mT release).

Electrical Compatibility: Supply voltage range (4.5V ~ 30V), maximum supply current (4.5mA), maximum output current (20mA), and open collector output configuration must be maintained.

Thermal Compatibility: Operating temperature range must span -40°C to 125°C to ensure performance across all specified test conditions.

Mechanical Compatibility: The substitute must use surface mount technology with the 8-MSOP package configuration (0.118", 3.00mm width) to ensure PCB layout and assembly process compatibility.

Series Designation: Parts must belong to the AD series from NVE Corp/Sensor Products to maintain manufacturer consistency and design validation.

Substitutes are grouped based on product status and compliance certifications, which affect long-term availability and regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

AD122-00E is the direct substitute for AD122-00. Both parts are electrically and mechanically identical across all functional parameters, sensing characteristics, and thermal specifications.

The primary distinction between these parts is product status and regulatory compliance:

AD122-00 carries obsolete status, indicating discontinued manufacturing and limited long-term availability. This part is RoHS non-compliant, which may restrict use in applications subject to RoHS3 regulations.

AD122-00E maintains active product status with full ROHS3 compliance. This part is supplied in tube packaging and represents the current production equivalent. Selection of AD122-00E is appropriate for new designs, production continuity, and applications requiring regulatory compliance with modern environmental standards.

For existing designs currently using AD122-00, direct substitution with AD122-00E requires no circuit modifications, PCB layout changes, or firmware adjustments. The 8-MSOP package footprint and electrical interface remain identical.

Frequently Asked Questions (FAQ)

Q: Can AD122-00E directly replace AD122-00 in existing circuit designs?

A: Yes. AD122-00E is a direct electrical and mechanical equivalent. No circuit modifications, PCB layout changes, or design validation is required. Both parts share identical supply voltage ranges, output current ratings, sensing thresholds, and 8-MSOP package dimensions.

Q: What is the primary reason to transition from AD122-00 to AD122-00E?

A: AD122-00 is obsolete with limited inventory availability. AD122-00E is the active production part from the same manufacturer and series, ensuring long-term supply chain continuity. Additionally, AD122-00E is ROHS3 compliant, meeting current regulatory requirements for environmental and hazardous substance restrictions.

Q: Are there any differences in thermal performance between AD122-00 and AD122-00E?

A: No. Both parts operate across the identical temperature range of -40°C to 125°C and share the same thermal specifications. Operating temperature performance is equivalent.

Q: Does the tube packaging of AD122-00E affect compatibility?

A: No. Packaging format (tube versus other formats) does not affect electrical performance or PCB assembly compatibility. The 8-MSOP package configuration and component footprint remain identical.

Q: What are the critical parameters that define substitution eligibility for this part?

A: Substitution is determined by equivalence in omnipolar Hall Effect function, ±5mT trip and ±2.5mT release thresholds, 4.5V to 30V supply voltage range, 4.5mA maximum supply current, 20mA maximum output current, open collector output type, -40°C to 125°C operating temperature, and 8-MSOP surface mount package configuration.

Q: Is AD122-00E suitable for applications requiring RoHS compliance?

A: Yes. AD122-00E is ROHS3 compliant. AD122-00 is RoHS non-compliant and should not be used in applications subject to RoHS3 regulatory requirements.
