Substitute Part Grouping Explanation

Substitution of the ATS642LSHTN-I1-T is determined by strict equivalence across the following critical parameters:

• Technology: Hall Effect digital switch
• Function: Special Purpose magnetic sensing
• Polarization: South Pole detection
• Output Type: Open Collector configuration
• Supply Voltage Range: 4V ~ 24V
• Operating Temperature Range: -40°C ~ 150°C
• Mounting Type: Through Hole
• Package Type: 4-SSIP Module
• Compliance: ROHS3 Compliant, REACH Unaffected

The ATS682LSHTN-T meets all substitution criteria as a direct equivalent from the same manufacturer with identical functional specifications and package configuration.

Parameter Comparison

Engineering Selection Recommendations

The ATS682LSHTN-T is a direct substitute for the ATS642LSHTN-I1-T based on equivalent electrical and mechanical specifications. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The substitute part maintains identical supply voltage range, operating temperature range, and package configuration. The maximum supply current specification of the substitute (16.8mA) is within acceptable tolerance relative to the original part (16mA). Both components are classified as not for new designs, reflecting their legacy status in the Allegro MicroSystems product line.

Frequently Asked Questions (FAQ)

Q: Can the ATS682LSHTN-T directly replace the ATS642LSHTN-I1-T in existing applications?

A: Yes. Both parts share identical functional specifications, supply voltage range (4V ~ 24V), operating temperature range (-40°C ~ 150°C), output type (open collector), and 4-SSIP module package configuration. Pin compatibility and electrical behavior are equivalent.

Q: Are there differences in supply current specifications between these parts?

A: The ATS682LSHTN-T has a maximum supply current of 16.8mA compared to 16mA for the ATS642LSHTN-I1-T. This difference is within normal manufacturing tolerance and does not affect substitution suitability.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the ATS642LSHTN-I1-T and ATS682LSHTN-T are ROHS3 compliant and REACH unaffected, with identical moisture sensitivity level (MSL 1 - Unlimited).

Q: What is the significance of the "not for new designs" status?

A: This designation indicates that both components are legacy products. While suitable for replacement and continued use in existing applications, Allegro MicroSystems recommends evaluating newer alternatives for new product development.

Q: Are the parts interchangeable in terms of package and mounting?

A: Yes. Both components use the 4-SSIP module package with through-hole mounting, ensuring mechanical and electrical interchangeability in PCB designs.
