Key Parameters

Substitute Part Grouping Explanation

Substitution of the DAC7631EBG4 is determined by strict equivalence across all critical electrical and mechanical parameters. The primary substitute, DAC7631EB, maintains identical specifications across resolution, settling time, output buffering, SPI interface, supply voltages, linearity performance, architecture, temperature range, and package form factor. The distinction between these parts lies in product status and packaging format: DAC7631EBG4 is discontinued and supplied in standard packaging, while DAC7631EB remains active in production with tube packaging availability.

Substitution is valid only when the following parameters match exactly:

• 16-bit resolution with single D/A converter
• 10µs settling time
• Buffered voltage output via SPI interface
• External reference configuration
• ±5V analog and 5V digital supply requirements
• ±2/±1 LSB linearity specifications
• R-2R architecture
• 20-SSOP surface mount package
• Industrial temperature range (-40°C to 85°C)

Parameter Comparison

Engineering Selection Recommendations

The DAC7631EB is the direct functional equivalent for the discontinued DAC7631EBG4. Both parts share identical electrical specifications, performance characteristics, and physical packaging. Selection of DAC7631EB is supported by its active product status, ensuring long-term availability and supply chain continuity. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial applications. The DAC7631EB is available in tube packaging format, which may require adjustment to procurement and handling procedures compared to the original part's standard packaging.

Frequently Asked Questions (FAQ)

Q: Can DAC7631EB directly replace DAC7631EBG4 in existing designs? A: Yes. Both parts are electrically and mechanically identical across all specified parameters. No circuit modifications or PCB redesign is required for substitution.
