AD124-00 Equivalent & Substitute Parts

Part Overview

The AD124-00 is an omnipolar Hall Effect magnetic switch manufactured by NVE Corp/Sensor Products. This digital switch operates as an open collector device and detects both north and south magnetic poles within a ±3.4mT trip threshold and ±1.4mT release threshold. The AD124-00 is classified as obsolete product status, making identification of active equivalent parts essential for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD124-00 is determined by strict equivalence across the following critical parameters:

Functional Parameters:

• Hall Effect technology with omnipolar detection capability
• Sensing range thresholds: ±3.4mT trip and ±1.4mT release
• Open collector output configuration
• 20mA maximum output current

Electrical Parameters:

• Supply voltage range: 4.5V ~ 30V
• Maximum supply current: 4.5mA
• Operating temperature range: -40°C ~ 125°C

Mechanical Parameters:

• Surface mount packaging
• 8-MSOP package footprint (0.118", 3.00mm Width)

Only parts matching all these parameters across function, electrical specifications, and mechanical form factor qualify as direct substitutes for the AD124-00.

Parameter Comparison

Engineering Selection Recommendations

AD124-00E as Direct Substitute:

The AD124-00E is a direct functional and electrical equivalent to the AD124-00. Both parts share identical Hall Effect omnipolar switching characteristics, sensing thresholds, supply voltage range, output current specifications, and 8-MSOP surface mount packaging.

Product Status Consideration:

The AD124-00 carries obsolete product status, while the AD124-00E is classified as active. For new designs and production continuity, the AD124-00E is the appropriate selection.

Compliance Advantage:

The AD124-00E achieves ROHS3 compliance, whereas the AD124-00 is RoHS non-compliant. This compliance improvement aligns with current regulatory requirements for electronic components in most markets.

Packaging:

The AD124-00E is supplied in tube packaging, which is standard for surface mount components in production environments.

Frequently Asked Questions (FAQ)

Q: Can AD124-00E directly replace AD124-00 in existing designs?

A: Yes. The AD124-00E provides identical electrical performance, sensing characteristics, and mechanical compatibility. The 8-MSOP package footprint, supply voltage range (4.5V ~ 30V), output current rating (20mA), and omnipolar Hall Effect switching function are equivalent across both parts.

Q: What is the primary difference between AD124-00 and AD124-00E?

A: The AD124-00E is the active production equivalent. Key differences include product status (active vs. obsolete) and RoHS compliance (ROHS3 compliant vs. non-compliant). All functional and electrical parameters remain identical.

Q: Are there any package or pinout differences?

A: No. Both parts use the 8-MSOP package with identical 0.118" (3.00mm) width. Pinout and mechanical footprint are equivalent, enabling direct PCB layout compatibility.

Q: What sensing thresholds apply to both parts?

A: Both AD124-00 and AD124-00E operate with ±3.4mT trip threshold and ±1.4mT release threshold. These omnipolar thresholds apply to both north and south pole detection.

Q: Is the AD124-00E suitable for -40°C to 125°C operating environments?

A: Yes. The AD124-00E maintains the full -40°C to 125°C operating temperature range specified for the AD124-00, supporting industrial and automotive applications within this thermal envelope.

Q: What output configuration do these parts use?

A: Both parts feature open collector output with 20mA maximum output current. External pull-up resistor configuration is required for logic-level signal generation.
