Substitute Part Grouping Explanation

Substitution of the A1180LUA-T is determined by strict equivalence across the following critical parameters:

• Function & Technology: Unipolar Switch with Hall Effect sensing
• Polarization: South Pole detection capability
• Sensing Range: Programmable trip point functionality
• Output Type: Current Source output configuration
• Mounting & Package: Through Hole mounting in 3-SSIP package
• Automotive Compliance: AEC-Q100 qualification and automotive grade
• Environmental Specifications: Operating temperature range -40°C to 150°C
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected

The A1190LUA-T meets all substitution criteria as an active product from the same manufacturer with identical functional characteristics, package configuration, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The A1190LUA-T is the direct substitute for the obsolete A1180LUA-T. Both components are manufactured by Allegro MicroSystems and maintain identical functional specifications, package configuration, and automotive-grade compliance certifications including AEC-Q100 qualification.

The A1190LUA-T carries active product status, ensuring continued availability for new designs and field service applications. Both parts comply with ROHS3 and REACH regulatory requirements, maintaining equivalent environmental and compliance posture.

The primary design consideration is the reduced maximum supply current specification of the A1190LUA-T (5mA versus 17mA). Circuit designs must verify that the lower current specification remains compatible with existing power supply and signal conditioning requirements. The minimum supply voltage specification of the A1190LUA-T (3V versus 4.6V) provides improved low-voltage operation capability.

Frequently Asked Questions (FAQ)

Q: Can the A1190LUA-T directly replace the A1180LUA-T in existing designs?

A: The A1190LUA-T is functionally equivalent in terms of switching operation, Hall Effect sensing, programmable trip point capability, and package configuration. Circuit designs must confirm that the reduced maximum supply current (5mA) and adjusted minimum supply voltage (3V) specifications are compatible with existing power and signal requirements.

Q: Are the package dimensions and pinout identical between these parts?

A: Both components utilize the 3-SSIP package with Through Hole mounting. Pinout and mechanical dimensions are equivalent, allowing direct PCB-level substitution without layout modifications.

Q: What compliance certifications apply to both parts?

A: Both the A1180LUA-T and A1190LUA-T carry AEC-Q100 automotive qualification, ROHS3 compliance, and REACH unaffected status. Both are rated for automotive-grade applications across the -40°C to 150°C operating temperature range.

Q: Why is the A1180LUA-T classified as obsolete?

A: The A1180LUA-T has reached end-of-life status. The A1190LUA-T represents the active product continuation from Allegro MicroSystems with equivalent functional performance and compliance certifications.

Q: Are there any electrical parameter differences that affect circuit design?

A: The A1190LUA-T specifies a maximum supply current of 5mA compared to 17mA for the A1180LUA-T, and a minimum supply voltage of 3V compared to 4.6V. Designs must verify compatibility with these specifications. The upper supply voltage limit (24V) and all switching characteristics remain equivalent.
