Engineering Selection Recommendations

Full Equivalents (4.4V Threshold, -40°C ~ 85°C Operating Range):

ADM706ARZ, ADM706ARZ-REEL, ADM706ARZ-REEL7, DS1706ESA+, MAX706ESA+, and MAX706ESA+T maintain the complete electrical specification envelope of the MIC706MY-TR, including the 4.4V voltage threshold and extended operating temperature range of -40°C ~ 85°C. These parts are suitable for applications requiring the full temperature specification. All are ROHS3 compliant with MSL 1 rating.

Conditional Substitutes (4.4V Threshold, 0°C ~ 70°C Operating Range):

MAX706CSA+ and MAX706CSA+T operate within a narrower temperature range (0°C ~ 70°C) compared to the MIC706MY-TR. These parts are suitable only for applications where the operating environment remains within 0°C to 70°C. Both maintain the 4.4V threshold and 140ms reset timeout specification.

Non-Equivalent (Different Voltage Threshold):

MAX706TCSA+ and MAX706TCSA+T feature a 3.08V voltage threshold, which differs from the MIC706MY-TR specification of 4.4V. These parts are not suitable substitutes for applications requiring 4.4V threshold monitoring.

All substitute parts listed are active in production status and ROHS3 compliant.

Frequently Asked Questions (FAQ)

Q: Can ADM706ARZ replace MIC706MY-TR in all applications?

A: ADM706ARZ matches the critical electrical parameters: 8-SOIC package, 4.4V threshold, active-low reset, and -40°C ~ 85°C operating temperature. The primary difference is output type (Push-Pull/Totem Pole versus unspecified on MIC706MY-TR) and reset timeout (160ms minimum versus 140ms minimum). Applications requiring the specified 140ms timeout or with output drive requirements must be evaluated against the ADM706ARZ datasheet.

Q: What is the difference between ADM706ARZ, ADM706ARZ-REEL, and ADM706ARZ-REEL7?

A: These three part numbers are electrically identical. The differences are in packaging format: ADM706ARZ is supplied in Tube, while ADM706ARZ-REEL and ADM706ARZ-REEL7 are supplied in Cut Tape (CT) & Digi-Reel® format. Selection depends on assembly process requirements and quantity needs.

Q: Why are MAX706TCSA+ and MAX706TCSA+T listed but not recommended?

A: These parts feature a 3.08V voltage threshold instead of the 4.4V threshold specified for MIC706MY-TR. They are not functionally equivalent for applications requiring 4.4V threshold monitoring and should not be used as substitutes.

Q: Can MAX706CSA+ be used in applications operating below 0°C or above 70°C?

A: No. MAX706CSA+ is rated for 0°C ~ 70°C operating temperature, while MIC706MY-TR operates -40°C ~ 85°C. Applications requiring operation outside the 0°C ~ 70°C range must use parts with extended temperature ratings such as ADM706ARZ, DS1706ESA+, MAX706ESA+, or MAX706ESA+T.

Q: What does the "+T" suffix indicate in part numbers like MAX706ESA+T?

A: The "+T" suffix indicates Cut Tape (CT) & Digi-Reel® packaging format, as opposed to Tube packaging. Electrically and functionally, MAX706ESA+ and MAX706ESA+T are identical; the difference is in supply format for manufacturing and assembly processes.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the environmental and regulatory compliance of MIC706MY-TR.
