A1386LUA-T Hall Effect Sensor Equivalent & Substitute Parts

Part Overview

The A1386LUA-T is a Hall Effect analog magnetic sensor manufactured by Allegro MicroSystems in a 3-SIP through-hole package. This single-axis sensor provides analog voltage output with temperature compensation and programmable features. The part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts must maintain functional compatibility while accommodating differences in supply voltage ranges, packaging formats, and product lifecycle status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the A1386LUA-T is determined by the following core parameters:

• Technology & Sensing Principle: Hall Effect single-axis analog voltage output
• Bandwidth: 20kHz minimum
• Operating Temperature Range: -40°C ~ 150°C
• Output Characteristics: Analog voltage with temperature compensation
• Compliance: ROHS3 compliant, REACH unaffected

The two qualified substitutes differ from the main part in supply voltage range and packaging format, but maintain functional equivalence in sensing technology, output type, bandwidth, and temperature performance. The A1319LLHLT-5-T operates at 3V ~ 3.63V in SOT-23W surface-mount packaging, while the A1319LUA-5-T operates at 3V ~ 3.63V in 3-SIP through-hole packaging. Both substitutes are classified as "Not For New Designs," indicating they represent transitional alternatives rather than long-term solutions.

Parameter Comparison

Engineering Selection Recommendations

A1319LUA-5-T is the primary substitute for through-hole applications. It maintains identical 3-SSIP packaging and through-hole mounting, enabling direct board-level replacement. The reduced supply voltage range (3V ~ 3.63V versus 4.5V ~ 5.5V) requires circuit redesign for power supply compatibility. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

A1319LLHLT-5-T is applicable only for surface-mount redesigns. The SOT-23W package represents a different form factor and requires PCB layout modification. This substitute is suitable when transitioning to surface-mount assembly processes.

Both substitutes are designated "Not For New Designs," indicating Allegro MicroSystems recommends evaluating newer Hall Effect sensor families for new product development. The A1386LUA-T obsolete status and substitute availability suggest a product line transition within the A1319 base product family.

Frequently Asked Questions (FAQ)

Q: Can A1319LUA-5-T directly replace A1386LUA-T in existing designs?

A: Electrical substitution is possible if the circuit power supply can be modified to operate at 3V ~ 3.63V. The 3-SSIP package and through-hole mounting are identical, eliminating PCB redesign. However, the reduced supply voltage range requires verification of circuit performance at the lower operating point.

Q: What is the key difference between the two substitutes?

A: A1319LUA-5-T maintains through-hole 3-SSIP packaging for direct board replacement. A1319LLHLT-5-T uses SOT-23W surface-mount packaging, requiring PCB layout modification and assembly process changes.

Q: Are both substitutes suitable for new product designs?

A: Both substitutes carry "Not For New Designs" status. Allegro MicroSystems recommends evaluating current-generation Hall Effect sensors for new applications. These substitutes are appropriate for legacy product support and existing design maintenance only.

Q: What compliance certifications apply to these substitutes?

A: Both A1319LLHLT-5-T and A1319LUA-5-T are ROHS3 compliant and REACH unaffected, matching the compliance profile of the A1386LUA-T.

Q: How do output current capabilities differ?

A: The A1386LUA-T specifies 2mA maximum output current. Both substitutes provide 10mA maximum output current, representing increased output drive capability. Circuit designs relying on the lower output impedance of the original part should verify compatibility with the higher output current specification.

Q: Is temperature compensation maintained in the substitutes?

A: Yes. Both substitutes include temperature compensation, matching the thermal performance characteristics of the A1386LUA-T across the -40°C ~ 150°C operating range.
