Substitute Part Grouping Explanation
Substitute parts for the MCP47FVB01A1-E/ST are identified based on strict parametric equivalence within the MCP47FVB01 product family. The substitution criteria are defined by the following key parameters that must remain identical:
- 8-bit resolution with single D/A converter configuration
- Buffered voltage output topology
- I2C serial data interface
- External, internal, and supply reference capability
- 2.7V to 5.5V dual supply voltage range
- R-2R converter architecture
- 6µs typical settling time
- ±0.1 and ±0.0125 LSB INL/DNL specifications
- 8-TSSOP surface mount package with 4.40mm width
- -40°C to 125°C operating temperature range
- ROHS3 compliance and MSL Level 1 rating
The MCP47FVB01A0-E/ST maintains all electrical and mechanical parameters identical to the main part, differing only in internal device configuration codes that do not affect functional performance in equivalent circuit applications.
