Substitute Part Grouping Explanation

Substitution eligibility for the A1183EUA-T is determined by strict alignment across the following critical parameters:

• Sensor Technology: Hall Effect unipolar switch function
• Polarization: South Pole detection capability
• Output Configuration: Current source output type
• Package Format: 3-SSIP through-hole mounting
• Electrical Compatibility: Supply voltage range and maximum supply current ratings
• Operating Temperature Range: Functional performance across specified thermal envelope
• Automotive Compliance: AEC-Q100 qualification and ROHS3 compliance

The A1193LUA-T meets all substitution criteria as an active, manufacturer-recommended equivalent from Allegro MicroSystems within the same product family.

Parameter Comparison

Engineering Selection Recommendations

The A1193LUA-T is the direct manufacturer-recommended substitute for the obsolete A1183EUA-T. Both components share identical functional specifications, sensor technology, output configuration, and automotive-grade qualifications. The A1193LUA-T maintains full AEC-Q100 certification and ROHS3 compliance, ensuring regulatory and quality standards alignment.

Key differences in electrical performance are favorable for most applications: the A1193LUA-T operates across an extended temperature range (-40°C to 150°C versus -40°C to 85°C) and exhibits lower maximum supply current consumption (6.9mA versus 17mA). The minimum supply voltage extends to 3V, providing enhanced low-voltage operation capability. These characteristics make the A1193LUA-T suitable for designs requiring improved thermal performance or reduced power consumption.

For applications with strict adherence to the original A1183EUA-T electrical envelope, circuit-level validation of the lower supply current specification is recommended during design transition.
