Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the A17201LUAA-I2 is determined by strict equivalence across the following critical parameters:

• Hall Effect technology implementation
• Sensing range specification (1.74mT Trip, -1.74mT Release)
• Supply voltage range (4.6V ~ 24V)
• Maximum supply current (16mA)
• Current source output type
• Operating temperature range (-40°C ~ 150°C)
• Through hole mounting configuration
• 3-SSIP package form factor
• Temperature compensation feature
• RoHS3 compliance status

The A17201LUAA-I1 meets all substitution criteria as an active product variant within the same base product family (A17201), maintaining identical electrical and mechanical specifications while offering improved availability.

Parameter Comparison

Engineering Selection Recommendations

The A17201LUAA-I1 is the direct substitute for the obsolete A17201LUAA-I2. Both components share identical electrical specifications, sensing characteristics, and mechanical form factors. The primary distinction is product status: the A17201LUAA-I1 maintains active production status with current inventory availability, while the A17201LUAA-I2 is obsolete.

Selection of the A17201LUAA-I1 is supported by:

• Identical Hall Effect sensing range and trip/release thresholds
• Matching supply voltage and current specifications
• Equivalent temperature compensation and operating range
• Identical 3-SSIP package configuration for direct PCB compatibility
• ROHS3 compliance maintained across both variants
• Active manufacturing status ensuring long-term supply chain continuity

Frequently Asked Questions (FAQ)

Q: Can the A17201LUAA-I1 be used as a direct replacement for the A17201LUAA-I2?

A: Yes. The A17201LUAA-I1 is electrically and mechanically equivalent to the A17201LUAA-I2. Both components feature identical Hall Effect sensing specifications, supply voltage ranges (4.6V ~ 24V), current source output characteristics, and 3-SSIP package form factors. The primary difference is product status: the A17201LUAA-I1 is active production while the A17201LUAA-I2 is obsolete.

Q: Are there any package compatibility considerations?

A: Both the A17201LUAA-I2 and A17201LUAA-I1 use the 3-SSIP package with through-hole mounting. PCB footprints and mounting requirements are identical. The A17201LUAA-I1 is available in Tape & Reel (TR) packaging for automated assembly, while the A17201LUAA-I2 standard packaging is no longer produced.

Q: What sensing range specifications must be matched for substitution?

A: The critical sensing specification is 1.74mT trip threshold and -1.74mT release threshold. Any substitute component must maintain these exact magnetic field detection parameters to ensure functional equivalence in the application circuit.

Q: Are compliance certifications maintained in the substitute part?

A: Yes. The A17201LUAA-I1 maintains ROHS3 compliance and REACH unaffected status identical to the A17201LUAA-I2, ensuring regulatory requirements are satisfied in both new designs and legacy system replacements.

Q: What is the temperature compensation feature and is it present in both parts?

A: Temperature compensation is a feature that maintains consistent sensor performance across the -40°C to 150°C operating range. Both the A17201LUAA-I2 and A17201LUAA-I1 include this feature, ensuring stable magnetic field detection across the full specified temperature envelope.
