Key Parameters

Substitute Part Grouping Explanation

The QT60326-ASG qualifies as a direct substitute for the QT60326-AS based on the following criteria:

Electrical Compatibility: Both parts maintain identical supply voltage range (4.75V ~ 5.25V), maximum supply current (25mA), operating temperature range (-40°C ~ 105°C), and resolution (9 b).

Functional Equivalence: Both components support the same number of input channels (up to 32), identical interface protocols (SPI and UART), and belong to the same QMatrix™ series.

Mechanical Compatibility: Both parts use identical packaging (44-TQFP with 10x10 dimensions) and surface mount mounting type, ensuring PCB layout compatibility.

Moisture Sensitivity: Both parts share the same MSL rating of 3 (168 Hours).

The primary distinction between these parts is product status and compliance certification, not electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations
