Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OPT4048DTST is determined by strict equivalence across the following critical parameters:

• Package / Case: SOT-583 (physical and thermal compatibility)
• Resolution: 20-bit (functional performance requirement)
• Output Interface: I2C (system integration requirement)
• Supply Voltage Range: 1.6 V ~ 3.6 V (power compatibility)
• Operating Temperature Range: -40°C ~ 85°C (environmental specification)

The OPT4048DTSR meets all substitution criteria as a direct functional equivalent. This part maintains identical electrical specifications and physical packaging while offering Active product status, ensuring continued availability and manufacturing support.
