AD020-00 Equivalent & Substitute Parts

Part Overview

The AD020-00 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. The AD020-00 is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The active equivalent AD020-00E provides functional continuity while offering improved compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD020-00 is determined by strict equivalence across the following critical parameters:

Functional Parameters: Omnipolar switch function with Hall Effect technology detecting both north and south magnetic poles.

Electrical Parameters: Supply voltage range 4.5V ~ 30V, maximum supply current 4.5mA, maximum output current 20mA, and open collector output configuration.

Sensing Parameters: Trip threshold ±3.4mT and release threshold ±1.4mT.

Thermal Parameters: Operating temperature range -40°C ~ 125°C.

Mechanical Parameters: Surface mount technology with 8-MSOP package (0.118", 3.00mm Width).

The AD020-00E qualifies as a direct substitute because it maintains identical electrical, sensing, thermal, and mechanical specifications while offering active product status and improved regulatory compliance.

Engineering Selection Recommendations

Primary Selection: AD020-00E is the recommended substitute for AD020-00 applications. This selection is based on the following engineering criteria:

Product Status: The AD020-00E maintains active product status, ensuring long-term availability and continued manufacturer support. The AD020-00 is obsolete and subject to discontinuation.

Regulatory Compliance: The AD020-00E is ROHS3 compliant, meeting current environmental and safety standards required in most markets. The AD020-00 is RoHS non-compliant and may not satisfy procurement requirements for new designs.

Functional Equivalence: Both parts maintain identical electrical specifications, sensing thresholds, thermal operating range, and mechanical package configuration. Direct pin-for-pin and functional compatibility is confirmed.

Supply Chain Continuity: The AD020-00E has 983 pieces in stock compared to 865 pieces for the AD020-00, providing improved availability for production requirements.

Frequently Asked Questions (FAQ)

Q: Can AD020-00E replace AD020-00 in existing designs?

A: Yes. The AD020-00E is a direct functional and electrical equivalent. Both parts share identical supply voltage (4.5V ~ 30V), output current (20mA maximum), sensing thresholds (±3.4mT trip, ±1.4mT release), operating temperature range (-40°C ~ 125°C), and 8-MSOP package configuration. No circuit modifications are required.

Q: What is the difference between AD020-00 and AD020-00E?

A: The primary differences are product status and regulatory compliance. AD020-00E is an active product with ROHS3 compliance, while AD020-00 is obsolete and RoHS non-compliant. All electrical and mechanical specifications are identical.

Q: Are there any package differences between these parts?

A: Both parts use the 8-MSOP package (0.118", 3.00mm Width). The AD020-00E is supplied in tube packaging, while the AD020-00 packaging is not specified. This does not affect electrical or mechanical compatibility.

Q: What is the omnipolar sensing capability?

A: Both parts detect magnetic fields from both north and south poles. The trip threshold is ±3.4mT, and the release threshold is ±1.4mT. This allows the switch to activate regardless of magnetic pole orientation.

Q: Are these parts suitable for -40°C to 125°C applications?

A: Yes. Both AD020-00 and AD020-00E are rated for -40°C ~ 125°C operating temperature range, making them suitable for industrial and automotive applications requiring extended thermal performance.

Q: What is the maximum output current for these switches?

A: The maximum output current is 20mA for both parts. The open collector output configuration allows direct interface with logic circuits and microcontroller inputs.
