Key Parameters

Substitute Part Grouping Explanation

Substitution of the A1160LLHLT-T is determined by the following critical parameters:

• Function & Technology: Unipolar Hall Effect switch with open drain output
• Polarization: South pole detection capability
• Supply Voltage Range: Compatibility with 3.8V to 24V operation
• Output Current Capability: Minimum 25mA output current requirement
• Sensing Characteristics: Trip and release thresholds suitable for magnetic field detection applications
• Thermal & Compliance: Operating temperature range -40°C to 150°C, AEC-Q100 automotive qualification
• Package Compatibility: Surface mount SOT-23-5 form factor

The substitute part APS11000LLHALX-0SH maintains functional equivalence through identical technology, polarization, output type, and automotive-grade qualification. Differences in sensing range thresholds and output current capability must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The APS11000LLHALX-0SH is the manufacturer-recommended substitute for the obsolete A1160LLHLT-T. Both components maintain identical automotive-grade qualification (AEC-Q100) and ROHS3 compliance status, ensuring regulatory continuity.

Key considerations for selection:

• Product Status: The APS11000LLHALX-0SH is active and in production, providing long-term supply chain stability compared to the obsolete A1160LLHLT-T.
• Sensing Threshold Differences: The substitute exhibits different trip and release thresholds (±7mT trip vs. 24.5mT trip). Application-specific magnetic field characteristics must align with these specifications.
• Output Current: The APS11000LLHALX-0SH provides 40mA maximum output current, exceeding the A1160LLHLT-T specification of 25mA, offering improved drive capability.
• Supply Current: The substitute operates at 4mA maximum supply current, slightly lower than the original 5mA specification.
• Package Form Factor: Both components use surface mount technology; however, package designations differ (SOT-23-5 Thin vs. SOT-23W). PCB layout compatibility must be verified.

Frequently Asked Questions (FAQ)

Q: Can the APS11000LLHALX-0SH directly replace the A1160LLHLT-T in existing designs?

A: Functional replacement is possible provided that the application's magnetic field detection thresholds align with the APS11000LLHALX-0SH sensing range (±7mT trip, ±0.5mT release). The different trip threshold (±7mT vs. 24.5mT) requires verification against your specific magnetic field environment. Both components share identical output type (open drain), operating temperature range, and automotive qualification.

Q: What are the key differences in electrical performance?

A: The primary differences are sensing range thresholds and output current capability. The APS11000LLHALX-0SH provides higher maximum output current (40mA vs. 25mA) and lower supply current (4mA vs. 5mA). Supply voltage ranges are compatible (3.3V to 24V for the substitute vs. 3.8V to 24V for the original).

Q: Are there package compatibility concerns?

A: Both components use surface mount technology in SOT-23 form factors. The A1160LLHLT-T uses SOT-23-5 Thin (TSOT-23-5), while the APS11000LLHALX-0SH uses SOT-23W. Physical dimensions and pin spacing should be verified against your PCB layout to ensure mechanical compatibility.

Q: Does the substitute maintain automotive compliance?

A: Yes. The APS11000LLHALX-0SH is AEC-Q100 qualified and ROHS3 compliant, matching the compliance profile of the original A1160LLHLT-T.

Q: What is the availability status of each part?

A: The A1160LLHLT-T is obsolete with limited remaining inventory (935 pcs). The APS11000LLHALX-0SH is active in production with current inventory availability (713 pcs), providing reliable long-term supply chain access.
