Substitute Part Grouping Explanation

The MCP47FVB11A2-E/ST qualifies MCP47FEB11A0-E/ST as a parametric equivalent based on the following critical substitution criteria:

Electrical Parameters Match:

• Resolution: 10-bit DAC architecture maintained
• Single D/A converter configuration identical
• Buffered voltage output type preserved
• I2C digital interface compatibility
• Analog and digital supply voltage ranges: 2.7V ~ 5.5V (identical)
• Settling time: 6µs typical (identical)
• INL/DNL specifications: ±0.4, ±0.05 LSB (identical)
• Reference type: External, Internal, Supply (identical)
• R-2R architecture maintained

Mechanical Parameters Match:

• Package type: 8-TSSOP (0.173", 4.40mm Width) - identical
• Surface mount mounting type - identical
• Operating temperature range: -40°C ~ 125°C - identical

Compliance & Status Match:

• Both components are Active product status
• RoHS3 Compliant
• REACH Unaffected
• MSL Level 1 (Unlimited)

The substitution is valid because all allowed electrical and mechanical parameters remain constant between the main part and substitute part.

Parameter Comparison

Engineering Selection Recommendations

Both the MCP47FVB11A2-E/ST and MCP47FEB11A0-E/ST are suitable for direct substitution in data acquisition circuits. Selection between these parts should be based on availability and inventory status rather than technical performance differences, as all electrical and mechanical specifications are identical.

The MCP47FEB11A0-E/ST currently maintains higher inventory availability (1187 pcs) compared to the MCP47FVB11A2-E/ST (1049 pcs), which may influence procurement decisions for high-volume production runs. Both components carry identical compliance certifications (RoHS3 Compliant, REACH Unaffected, MSL Level 1), ensuring equivalent environmental and regulatory qualification for end-use applications.
