Substitute Part Grouping Explanation

Substitution for the DAC7802LUG4 is determined by strict equivalence across the following critical parameters:

• 12-bit resolution with dual D/A converter channels
• 800ns settling time performance
• Current output, unbuffered configuration
• Parallel data interface with external reference
• 5V analog and digital supply voltages
• ±0.5 LSB INL and ±1 LSB DNL specifications
• R-2R architecture
• 24-SOIC surface mount package
• -40°C to 85°C operating temperature range
• ROHS3 compliance and MSL 3 rating

Two substitute parts meet these criteria: DAC7802LU (MFR Recommended) and DAC7801LU (Parametric Equivalent). Both maintain identical electrical specifications and package requirements, with differences limited to product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

DAC7802LU is the primary substitute for DAC7802LUG4. Both parts share identical electrical specifications, package configuration, and compliance certifications. DAC7802LU maintains active product status with higher inventory availability (1148 units), ensuring supply chain continuity.

DAC7801LU serves as a parametric equivalent with all electrical and mechanical specifications matching the original part. This substitute is also in active production with the highest inventory level (4148 units) among available options. Selection between DAC7802LU and DAC7801LU depends on design requirements specific to the base product number designation.

Both substitutes maintain ROHS3 compliance and MSL 3 rating, ensuring compatibility with standard manufacturing and storage protocols. No performance degradation occurs when substituting either part in applications designed for the DAC7802LUG4.

Frequently Asked Questions (FAQ)

Q: Can DAC7802LU directly replace DAC7802LUG4 in existing designs?

A: Yes. DAC7802LU is electrically and mechanically identical to DAC7802LUG4. The primary difference is product status (active vs. discontinued) and packaging format designation. No circuit modifications are required.

Q: What is the difference between DAC7802LU and DAC7801LU?

A: Both parts are parametric equivalents with identical electrical specifications, settling time, resolution, and package configuration. The distinction lies in the base product number (DAC7802 vs. DAC7801). Selection should be based on design documentation and application requirements.

Q: Are the substitute parts compatible with the same PCB footprint?

A: Yes. Both DAC7802LU and DAC7801LU use the 24-SOIC package with identical dimensions (0.295" × 7.50mm width). PCB footprints are directly compatible without modification.

Q: Do the substitute parts meet the same compliance requirements?

A: Yes. Both DAC7802LU and DAC7801LU are ROHS3 compliant with MSL 3 rating (168 hours), matching the original DAC7802LUG4 specifications.

Q: Which substitute should be selected for new production?

A: DAC7802LU is the manufacturer-recommended substitute. DAC7801LU is available as an alternative parametric equivalent. Both are in active production with adequate inventory levels for production requirements.
