Key Parameters

Substitute Part Grouping Explanation

Substitution of the ATS636LSETN-T is determined by the following critical parameters:

• Technology: Hall Effect magnetic sensing technology
• Package Type: 4-SIP with 4-SSIP formed leads for through-hole mounting compatibility
• Supply Voltage Range: Minimum 4.2V operation requirement
• Output Current Capability: 20mA maximum output current
• Operating Temperature Range: -40°C to 150°C thermal envelope
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status

The ATS128LSETN-T qualifies as a manufacturer-recommended substitute based on matching package geometry, mounting type, thermal operating range, current specifications, and regulatory compliance. However, the output type differs: the ATS636LSETN-T provides open collector output, while the ATS128LSETN-T provides analog voltage output. This functional difference requires circuit-level evaluation for compatibility.

Parameter Comparison

Engineering Selection Recommendations

The ATS128LSETN-T is the manufacturer-recommended substitute for the obsolete ATS636LSETN-T. Both components maintain identical package geometry, mounting configuration, current specifications, and thermal operating range. The substitute part carries active product status with ROHS3 compliance and REACH unaffected designation, ensuring regulatory alignment and supply chain availability.

The primary design consideration is the output type transition from open collector to analog voltage. The ATS128LSETN-T's lower minimum supply voltage (3V versus 4.2V) provides expanded operating range compatibility. Both devices support the same maximum output current of 20mA and identical supply current draw of 5.5mA, enabling direct electrical substitution in applications where analog voltage output is acceptable.

Frequently Asked Questions (FAQ)

Q: Can the ATS128LSETN-T directly replace the ATS636LSETN-T in existing designs?

A: Physical and electrical substitution is possible due to identical package type, mounting method, and current specifications. However, the output type differs: the ATS636LSETN-T provides open collector output while the ATS128LSETN-T provides analog voltage output. Circuit compatibility depends on whether the receiving circuit can accept analog voltage input instead of open collector logic levels.

Q: What is the significance of the product status change from Obsolete to Active?

A: The ATS128LSETN-T carries active product status, indicating ongoing manufacturer support, continued availability, and compliance with current regulatory standards. This ensures long-term supply chain reliability compared to the obsolete ATS636LSETN-T.

Q: Are the thermal operating ranges equivalent between these parts?

A: Both components operate across -40°C to 150°C. The ATS636LSETN-T specifies this range as junction temperature (TJ), while the ATS128LSETN-T specifies ambient temperature (TA). This distinction reflects different measurement methodologies but indicates equivalent thermal capability for the 4-SIP package form factor.

Q: Does the lower minimum supply voltage of the ATS128LSETN-T affect compatibility?

A: The ATS128LSETN-T operates from 3V minimum compared to 4.2V for the ATS636LSETN-T. This represents expanded operating range capability. Existing designs operating at 4.2V or higher will function within the substitute part's specification envelope.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the ATS636LSETN-T and ATS128LSETN-T maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for applications subject to these environmental and hazardous substance restrictions.
