Substitute Part Grouping Explanation

Substitution of the TLV1391CDBVT is determined by strict equivalence across the following critical parameters:

• Differential comparator topology with single element configuration
• Open-collector output stage capable of 20mA typical output current
• Supply voltage range of 2V to 7V
• Input offset voltage specification of 5mV maximum at 5V
• Input bias current specification of 0.25µA maximum at 5V
• Quiescent current specification of 175µA maximum
• SOT-23-5 surface mount package with SC-74A, SOT-753 case designation
• Operating temperature range of 0°C to 70°C
• ROHS3 compliance and REACH unaffected status

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. The TLV1391CDBVR maintains complete electrical and mechanical compatibility with the TLV1391CDBVT while offering active product status.
