Engineering Selection Recommendations

AD022-00E as Primary Substitute:

The AD022-00E is a direct functional and electrical equivalent to the AD022-00. All critical parameters—sensing thresholds, supply voltage range, output current capacity, operating temperature range, and package form factor—are identical between the two components.

Compliance and Status Advantages:

The AD022-00E carries an Active product status, ensuring ongoing manufacturer support and availability. The component is ROHS3 compliant, meeting current environmental and regulatory requirements for new designs and production runs. The AD022-00 is classified as RoHS non-compliant and obsolete, presenting long-term supply and regulatory compliance risks.

Inventory and Packaging Considerations:

The AD022-00E is available in higher inventory quantities (2100 pieces) compared to the AD022-00 (668 pieces), supporting sustained production requirements. The AD022-00E is supplied in tube packaging, which is standard for surface mount components and facilitates automated assembly processes.

Application Continuity:

Direct substitution of AD022-00E for AD022-00 maintains full electrical and mechanical compatibility. No circuit modifications, firmware adjustments, or board layout changes are required. The component operates identically within the specified parameter ranges across all supported applications.

Frequently Asked Questions (FAQ)

Q: Can AD022-00E replace AD022-00 in existing designs without modification?

A: Yes. The AD022-00E is electrically and mechanically identical to the AD022-00 across all functional parameters. No circuit changes, PCB layout modifications, or firmware updates are necessary. Direct substitution is supported.

Q: What is the primary reason to transition from AD022-00 to AD022-00E?

A: The AD022-00 is classified as obsolete, creating supply chain risk and limiting long-term availability. The AD022-00E is an active product with higher inventory levels, ROHS3 compliance, and ongoing manufacturer support, ensuring design continuity and regulatory alignment.

Q: Are the magnetic sensing thresholds identical between AD022-00 and AD022-00E?

A: Yes. Both components operate with identical trip thresholds of ±5mT and release thresholds of ±2.5mT. Omnipolar detection capability (north and south pole sensitivity) is identical.

Q: Do the supply voltage and current specifications match between these components?

A: Yes. Both components support 4.5V to 30V supply voltage range, with maximum supply current of 4.5mA and maximum output current of 20mA. Operating temperature range is identical at -40°C to 125°C.
