Key Parameters

Substitute Part Grouping Explanation

Substitute components for the CAT1232LPV-G are identified based on strict electrical and mechanical parameter equivalence. The following criteria determine substitution validity:

Critical Matching Parameters:

• Single-channel voltage monitoring architecture
• Voltage threshold levels: 4.37V and 4.62V
• Output type: Open Drain and Push-Pull capability
• Reset logic: Active High/Active Low selectable operation
• Reset timeout: Adjustable/Selectable configuration
• Operating temperature range: -40°C to 85°C
• Package type: 8-SOIC form factor with 0.154" (3.90mm) width
• Mounting method: Surface Mount

The DS1232LPSN-2+ from Analog Devices Inc./Maxim Integrated meets all specified electrical and mechanical parameters, providing direct functional equivalence for the obsolete CAT1232LPV-G.

Parameter Comparison

Engineering Selection Recommendations

The DS1232LPSN-2+ is the qualified substitute for the obsolete CAT1232LPV-G based on complete electrical and mechanical parameter equivalence. The substitute part maintains active product status with Analog Devices Inc./Maxim Integrated, ensuring ongoing availability and technical support.
