Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MCP47FEB04T-20E/ST are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

• Resolution and Channel Count: 8-bit resolution with 4 independent DAC channels
• Output Configuration: Buffered voltage output with differential output capability
• Digital Interface: I2C communication protocol
• Supply Voltage Ranges: Identical analog and digital supply voltage specifications (2.7V ~ 5.5V)
• Accuracy Specifications: INL/DNL performance metrics (±0.1, ±0.0125 LSB)
• Settling Time: 6µs response time
• Package Specification: 20-TSSOP surface mount package with identical physical dimensions
• Compliance Standards: RoHS3 compliance and REACH unaffected status
• Operating Temperature Range: -55°C ~ 125°C

The MCP47FVB04T-20E/ST qualifies as a parametric equivalent substitute because it maintains identical specifications across all these critical parameters while originating from the same manufacturer series.
