Substitute Part Grouping Explanation

Substitution of the TPIC46L02DB is determined by strict equivalence across the following critical parameters:

• Driven Configuration: Low-Side operation
• Number of Drivers: 6 independent channels
• Gate Type: N-Channel MOSFET
• Input Type: Non-Inverting logic
• Supply Voltage Range: 4.5V ~ 5.5V
• Peak Output Current: 1.2mA source and sink capability
• Package Type: 28-SSOP surface mount
• Thermal Operating Range: -40°C ~ 150°C

The TPIC46L02DBR qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is product status: TPIC46L02DBR is Active, whereas TPIC46L02DB is Last Time Buy.
