MCP47FEB08-20E/ST Equivalent & Substitute Parts

Part Overview

The MCP47FEB08-20E/ST is an 8-bit Digital to Analog Converter (DAC) manufactured by Microchip Technology, designed for data acquisition applications requiring voltage output conversion. This component features 8 independent D/A converters with a 6µs settling time, I2C data interface, and support for both buffered and unbuffered voltage outputs. The device is currently in active production status and maintains full ROHS3 compliance with REACH unaffected classification.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same product category, enabling direct replacement in circuit designs without functional degradation.

Substitute Part Grouping Explanation

Substitution eligibility for the MCP47FEB08-20E/ST is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• 8-bit resolution with 8 independent D/A converters
• 6µs settling time performance
• Voltage output capability (buffered and unbuffered modes)
• I2C serial data interface
• External and supply reference type support
• ±0.25 LSB maximum INL/DNL specification
• -40°C to 125°C operating temperature range

Mechanical Equivalence Criteria:

• 20-TSSOP package with 0.173" width (4.40mm)
• Surface mount configuration
• MSL 3 moisture sensitivity rating

Compliance Equivalence Criteria:

• ROHS3 compliance status
• REACH unaffected classification

Parts meeting all three equivalence categories are classified as direct parametric equivalents and may be substituted without circuit redesign.
