Key Parameters

Substitute Part Grouping Explanation

Substitution of the A1323EUA-T is based on the following critical parameters that must remain consistent:

• Technology & Sensing Method: Hall Effect analog voltage output
• Axis Configuration: Single-axis magnetic field detection
• Package & Mounting: 3-SSIP package with through-hole mounting
• Supply Voltage Compatibility: 4.5V ~ 5.5V operating range
• Output Current Capability: 10mA maximum output current
• Compliance Standards: ROHS3 compliance and REACH unaffected status

The A1326LUA-T qualifies as a manufacturer-recommended substitute based on matching these core electrical and mechanical parameters. Both components share identical supply voltage ranges, output current specifications, package configurations, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The A1326LUA-T is the manufacturer-recommended substitute for the obsolete A1323EUA-T. Both components maintain identical electrical specifications for supply voltage, output current, and package configuration, ensuring direct compatibility in existing circuit designs.

The A1326LUA-T offers extended operating temperature capability (-40°C to 150°C versus -40°C to 85°C), providing enhanced performance margin for applications requiring operation at elevated temperatures. The substitute component is currently in active production status with established supply chain availability, addressing the obsolescence of the original part.

Both components maintain equivalent RoHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and legacy system support.

Frequently Asked Questions (FAQ)

Q: Can the A1326LUA-T directly replace the A1323EUA-T in existing designs?

A: Yes. Both components share identical supply voltage ranges (4.5V ~ 5.5V), output current specifications (10mA maximum), package types (3-SSIP), and mounting methods (through-hole). No circuit modifications are required for direct substitution.

Q: What is the difference in bandwidth between these two sensors?

A: The A1323EUA-T operates at 30kHz bandwidth, while the A1326LUA-T operates at 17kHz. Applications requiring the full 30kHz bandwidth specification must evaluate whether the reduced bandwidth of the substitute meets system performance requirements.

Q: Why is the A1326LUA-T rated for higher operating temperatures?

A: The A1326LUA-T extends the maximum operating temperature to 150°C compared to the A1323EUA-T's 85°C limit. This represents an enhanced design variant from the same manufacturer, providing greater thermal margin for industrial applications.

Q: Are there any supply current differences between these parts?

A: The A1326LUA-T specifies a maximum supply current of 9mA compared to the A1323EUA-T's 8mA. This represents a minor increase and remains compatible with standard power supply designs.

Q: What is the packaging format for both components?

A: Both the A1323EUA-T and A1326LUA-T use the 3-SSIP (3-pin Single Small In-line Package) with through-hole mounting, ensuring identical PCB footprint and assembly compatibility.

Q: Are both components RoHS compliant?

A: Yes. Both the A1323EUA-T and A1326LUA-T are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component manufacturing and use.
