Key Parameters

Substitute Part Grouping Explanation

Substitution of the CAT810LSDI-GT3 is determined by strict equivalence across the following critical parameters:

• Functional Type: Simple Reset/Power-On Reset supervisor
• Number of Channels: Single channel (1 voltage monitored)
• Voltage Threshold: 4.63V
• Output Type: Push-Pull, Totem Pole configuration
• Reset Logic: Active High
• Reset Timeout: 140ms Minimum
• Package: SC-70 / SOT-323 (surface mount, 3-pin)
• Operating Temperature: -40°C ~ 85°C (TA)
• Moisture Sensitivity: MSL 1 (Unlimited)

The substitute part MIC810LYC3-TR meets all these parameters and is manufactured by Microchip Technology. This part maintains functional and electrical equivalence while offering active product status and improved supply availability.
