Substitute Part Grouping Explanation

Substitution of the A1182LUA-T with the A1192LUA-T is based on the following critical parameters:

  • Technology Match: Both components utilize Hall Effect technology for magnetic sensing
  • Function Equivalence: Both operate as unipolar switches with current source output
  • Polarization Compatibility: Both detect South Pole magnetic fields
  • Package Compatibility: Both use 3-SSIP through-hole mounting
  • Automotive Grade: Both meet AEC-Q100 automotive qualification standards
  • Compliance Alignment: Both are ROHS3 compliant with identical MSL ratings
  • Temperature Range: Both support -40°C ~ 150°C operating temperature
  • Supply Voltage Overlap: A1192LUA-T supply range (3V ~ 24V) encompasses the A1182LUA-T requirement (4.6V ~ 24V)

The A1192LUA-T represents an active product with manufacturer support, addressing the obsolescence status of the A1182LUA-T while maintaining functional and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the A1192LUA-T directly replace the A1182LUA-T in existing designs?

A: Yes. Both components share identical package geometry (3-SSIP), mounting type (through-hole), and functional characteristics (Hall Effect unipolar switch with current source output). Direct PCB substitution is supported without layout modifications.

Q: What is the primary difference between these components?

A: The A1182LUA-T is obsolete, while the A1192LUA-T is an active product. The A1192LUA-T also features a lower maximum supply current (6.9mA versus 17mA) and a broader supply voltage range (3V minimum versus 4.6V minimum).

Q: Are there any compliance or certification differences?

A: No. Both components maintain identical automotive-grade classification, AEC-Q100 qualification, ROHS3 compliance, and MSL rating of 1 (Unlimited).

Q: Does the lower supply current of the A1192LUA-T affect compatibility?

A: The lower maximum supply current specification of the A1192LUA-T does not prevent substitution. System-level current requirements must be evaluated against the 6.9mA maximum rating to ensure adequate operational margin.

Q: Are there packaging or moisture sensitivity considerations?

A: Both components use identical 3-SSIP through-hole packaging with MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: What is the temperature operating range for both components?

A: Both the A1182LUA-T and A1192LUA-T operate across -40°C to 150°C (TA), providing identical thermal performance specifications for automotive applications.
