Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLC7733IPWRG4 is determined by strict equivalence across the following critical parameters:

• Single voltage monitoring channel with 2.93V threshold
• Push-pull, totem pole output configuration
• Active high/active low reset capability
• 1.1ms minimum reset timeout
• 8-TSSOP surface mount package
• Operating temperature range of -40°C to 85°C
• ROHS3 compliance and MSL Level 1 rating

The TLC7733IPWR meets all these requirements and qualifies as a direct functional equivalent. The primary distinction between these parts is product status and packaging format availability.
