Parameter Comparison

Engineering Selection Recommendations

The A1326LUA-T is the manufacturer-recommended substitute for the obsolete A1323LUA-T. Both components maintain identical supply voltage specifications, operating temperature ranges, and package configurations, ensuring direct compatibility in existing circuit designs. The A1326LUA-T carries active product status with full ROHS3 and REACH compliance certification, providing long-term availability and regulatory assurance for production applications. The substitute exhibits marginally higher maximum supply current (9mA versus 8mA) and reduced bandwidth (17kHz versus 30kHz), which remain within acceptable operational parameters for standard Hall Effect analog sensing applications. Current inventory availability of the A1326LUA-T (16,372 units) supports immediate procurement for design transitions.

Frequently Asked Questions (FAQ)

Q: Can the A1326LUA-T be used as a direct replacement for the A1323LUA-T in existing PCB designs?

A: Yes. Both components share identical 3-SSIP through-hole package geometry, pin configuration, and supply voltage specifications (4.5V ~ 5.5V). No PCB layout modifications are required for substitution.

Q: What are the key electrical differences between these two sensors?

A: The A1326LUA-T operates at a maximum supply current of 9mA compared to 8mA for the A1323LUA-T, and provides 17kHz bandwidth versus 30kHz. Both maintain identical output current capability (10mA maximum) and temperature compensation features across the -40°C to 150°C operating range.

Q: Is the A1326LUA-T suitable for high-frequency magnetic field detection applications?

A: The A1326LUA-T bandwidth specification of 17kHz is appropriate for standard industrial and automotive magnetic sensing applications. Applications requiring response frequencies exceeding 17kHz should be evaluated against specific system requirements.

Q: What is the regulatory compliance status of the A1326LUA-T?

A: The A1326LUA-T is ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations for electronic components in industrial and consumer applications.

Q: Why is the A1323LUA-T classified as obsolete?

A: The A1323LUA-T has reached end-of-life status in the manufacturer's product portfolio. The A1326LUA-T represents the active successor product, maintaining functional equivalence while providing ongoing manufacturing support and regulatory compliance.
