Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AD123-00 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Omnipolar switch function with Hall Effect technology
• Sensing range: ±10mT trip threshold and ±6.5mT release threshold
• Supply voltage range: 4.5V ~ 30V
• Maximum supply current: 4.5mA
• Maximum output current: 20mA
• Open collector output configuration

Mechanical & Environmental Parameters:

• Surface mount technology
• 8-MSOP package footprint (0.118", 3.00mm width)
• Operating temperature range: -40°C ~ 125°C

Compliance Parameters:

• REACH unaffected status
• ECCN classification: EAR99
• HTSUS code: 8542.39.0001

Parts meeting all these criteria are classified as direct substitutes. Variations in product status (active vs. obsolete) and RoHS compliance do not affect functional substitutability but influence procurement and regulatory considerations.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Production Continuity:

The AD123-00E is the direct functional equivalent of the obsolete AD123-00. Both components share identical electrical specifications, sensing characteristics, and mechanical form factors. Selection of AD123-00E is appropriate for:

• Replacement of obsolete AD123-00 inventory in active production
• New design implementations requiring omnipolar Hall Effect magnetic switching
• Applications within the -40°C ~ 125°C operating range with 4.5V ~ 30V supply voltage

Compliance Considerations:

The AD123-00E provides improved regulatory compliance through ROHS3 certification, whereas the original AD123-00 is RoHS non-compliant. Both parts maintain REACH unaffected status and EAR99 ECCN classification. Organizations subject to RoHS requirements should prioritize AD123-00E for new procurement.

Packaging and Inventory:

AD123-00E is supplied in tube packaging, differing from the unspecified packaging of the original part. Current inventory availability is 843 pieces for AD123-00E, supporting immediate procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can AD123-00E directly replace AD123-00 in existing circuit designs?

A: Yes. The AD123-00E provides identical electrical performance, sensing thresholds, output characteristics, and package footprint. No circuit modifications are required for substitution.

Q: What is the primary reason for identifying substitute parts for AD123-00?
