Key Parameters

Substitute Part Grouping Explanation

Substitution of the MCP47FVB24T-20E/ST is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Number of bits (12), number of D/A converters (4), output type (voltage-buffered), data interface (I2C), settling time (6µs), architecture (R-2R), supply voltage ranges (2.7V ~ 5.5V for both analog and digital), and linearity specifications (INL/DNL ±0.1, ±0.0125 LSB).

Environmental & Operational: Operating temperature range (-55°C ~ 125°C), reference type (external), and differential output capability (yes).

Physical & Compliance: Package configuration (20-TSSOP with 0.173" width, 4.40mm), surface mount mounting type, RoHS3 compliance, MSL rating (3), REACH unaffected status, and ECCN/HTSUS classifications.

Product Status: Only Active status components qualify as direct substitutes.

The MCP47FEB24T-20E/ST meets all substitution criteria and is classified as a parametric equivalent.

Parameter Comparison
