Key Parameters

Substitute Part Grouping Explanation

Selection of substitute parts for the MIC8115TU TR Supervisor IC is strictly based on identical key electrical and mechanical parameters. Critical dimensions are: Voltage - Threshold at 3.08V, Push-Pull output configuration, Active Low reset, identical reset timeout, and equivalent temperature rating. Mechanical interchangeability requires matching mounting type, package/case, and supplier device footprint. Substitute candidates must maintain consistent compliance and certification statuses for regulatory purposes.

Key substitution parameters:

• Voltage - Threshold: 3.08V
• Number of Voltages Monitored: 1
• Output: Push-Pull, Totem Pole
• Reset: Active Low
• Reset Timeout: 1.1s Minimum
• Operating Temperature: -40°C ~ 85°C
• Package / Case: TO-253-4, TO-253AA (SOT-143)
• Mounting Type: Surface Mount

Parameter Comparison

Engineering Selection Recommendations

The MIC8115TU TR is Obsolete and RoHS non-compliant, while the MIC8115TUY-TR is Active and ROHS3 Compliant. Both models meet identical electrical and mechanical key parameters based on provided data, supporting direct substitution with the MIC8115TUY-TR for continuity in compliant designs and regulatory environments.

Frequently Asked Questions (FAQ)

Q: What are the mandatory electrical parameters for substituting MIC8115TU TR with MIC8115TUY-TR?
A: Substitute selection requires matching voltage threshold, number of voltages monitored, output type, active low reset, reset timeout, and operating temperature range.

Q: Is package compatibility assured between MIC8115TU TR and MIC8115TUY-TR?
