Key Parameters

Substitute Part Grouping Explanation

Substitution of the A1322LLHLT-T is determined by strict alignment of the following critical parameters:

• Technology: Hall Effect sensor architecture
• Axis Configuration: Single-axis magnetic field detection
• Output Type: Analog voltage output
• Supply Voltage Range: 4.5V ~ 5.5V compatibility
• Package Type: SOT-23W form factor
• Mounting Type: Surface mount configuration
• Operating Temperature Range: -40°C ~ 150°C
• Temperature Compensation: Required feature

The A1325LLHLX-T meets all substitution criteria as a manufacturer-recommended equivalent. Both components share identical technology, axis configuration, output type, supply voltage range, package type, mounting type, and operating temperature specifications. The substitute maintains temperature compensation and RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

The A1325LLHLX-T is the manufacturer-recommended substitute for the obsolete A1322LLHLT-T. Both components maintain identical electrical and mechanical specifications across all critical parameters, ensuring direct functional compatibility in existing circuit designs.

The A1325LLHLX-T carries active product status with higher inventory availability (10,100 pcs in stock versus 805 pcs for the main part), providing superior supply chain reliability. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current manufacturing standards.

The substitute exhibits a 1mA increase in maximum supply current (9mA versus 8mA) and a 13kHz reduction in bandwidth (17kHz versus 30kHz). These parameter variations remain within acceptable tolerance for applications requiring single-axis Hall Effect analog sensing in the specified voltage and temperature ranges.

Frequently Asked Questions (FAQ)

Q: Can the A1325LLHLX-T directly replace the A1322LLHLT-T in existing designs?

A: Yes. Both components share identical supply voltage range (4.5V ~ 5.5V), operating temperature range (-40°C ~ 150°C), package type (SOT-23W), mounting configuration (surface mount), and output characteristics (analog voltage, single-axis Hall Effect). Pin-to-pin compatibility is maintained.

Q: What are the differences between these two parts?

A: The A1325LLHLX-T has a maximum supply current of 9mA compared to 8mA for the A1322LLHLT-T, and a bandwidth of 17kHz versus 30kHz. The substitute is actively manufactured and has higher inventory availability.

Q: Does the bandwidth difference affect circuit performance?

A: Bandwidth differences depend on application requirements. The A1322LLHLT-T supports 30kHz bandwidth while the A1325LLHLX-T supports 17kHz. Applications requiring response frequencies above 17kHz may require design evaluation.

Q: Are both parts RoHS compliant?

A: Yes. Both the A1322LLHLT-T and A1325LLHLX-T are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What packaging options are available for the substitute?

A: The A1325LLHLX-T is supplied in Tape & Reel (TR) packaging for automated assembly processes, while the main part does not specify packaging format in the provided data.
