Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLC7528CFN are classified based on the following allowed electrical and mechanical parameters:

Parametric Equivalents maintain identical specifications across all critical parameters: 8-bit resolution, dual DAC channels, R-2R architecture, 100ns settling time, unbuffered current output, parallel data interface, external reference, 5V–15V dual supply range, ±0.5 LSB INL/DNL, 0°C–70°C operating temperature, and 20-PLCC package form factor.

Manufacturer-Recommended Substitutes share the same functional category (8-bit dual DAC, parallel interface, external reference, unbuffered current output, R-2R architecture) and package footprint (20-PLCC) but may differ in settling time, INL/DNL accuracy, or supply voltage specifications. These parts are suitable when application timing and accuracy requirements permit relaxed specifications.

Cross-Manufacturer Alternatives from Analog Devices Inc./Maxim Integrated provide equivalent 8-bit dual DAC functionality in the same 20-PLCC package with comparable electrical performance, enabling design flexibility across multiple supply sources.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Parametric Equivalent): TLC7528CFNG3 is the primary equivalent, offering identical electrical specifications and 20-PLCC package compatibility. This part maintains active product status, ensuring long-term availability and supply chain stability compared to the Last Time Buy status of TLC7528CFN.

Cross-Manufacturer Substitutes (Maxim Integrated MX7528 Series): MX7528JP+, MX7528JP+T, and MX7528KP+ provide functional equivalence with identical 8-bit resolution, dual DAC channels, R-2R architecture, and 20-PLCC package footprint. These parts are suitable for applications where settling time relaxation from 100ns to 400ns and INL/DNL tolerance increase from ±0.5 LSB to ±1 LSB (or ±0.5/±1 for MX7528KP+) are acceptable. All three maintain active product status and ROHS3 compliance.

Not Recommended for Direct Substitution: DAC7802KU/1K differs fundamentally in resolution (12-bit vs. 8-bit), architecture (Multiplying DAC vs. R-2R), package (24-SOIC vs. 20-PLCC), and supply voltage specification (5V fixed vs. 5V–15V range). This part is suitable only for applications requiring higher resolution and different functional characteristics.

Frequently Asked Questions (FAQ)

Q: Can TLC7528CFNG3 replace TLC7528CFN in existing designs? A: Yes. TLC7528CFNG3 is a parametric equivalent with identical electrical specifications, package footprint, and pin configuration. The primary difference is active product status versus Last Time Buy classification.

Q: What are the key differences between TLC7528CFN and MX7528 series parts? A: The MX7528 series (JP+, JP+T, KP+) maintains 8-bit resolution, dual channels, R-2R architecture, and 20-PLCC packaging. Differences include settling time (400ns vs. 100ns) and INL/DNL tolerance (±1 LSB vs. ±0.5 LSB for most parameters). MX7528KP+ offers ±0.5 LSB INL accuracy, improving compatibility.

Q: Are the MX7528 variants (JP+, JP+T, KP+) interchangeable? A: MX7528JP+ and MX7528JP+T share identical electrical specifications and differ only in packaging designation. MX7528KP+ offers tighter INL specification (±0.5 LSB vs. ±1 LSB) while maintaining the same settling time and DNL tolerance. All three are pin-compatible in the 20-PLCC package.

Q: Why is DAC7802KU/1K listed but not recommended? A: DAC7802KU/1K is a 12-bit multiplying DAC in a 24-SOIC package. It is fundamentally different in resolution, architecture, and form factor, making it unsuitable for direct substitution despite Texas Instruments manufacture.

Q: What compliance certifications apply to all substitute parts? A: All listed parts maintain ROHS3 compliance and REACH unaffected status. MSL ratings vary: TLC7528CFN and all MX7528 variants are MSL 1 (Unlimited); TLC7528CFNG3 is MSL 1 (Unlimited); DAC7802KU/1K is MSL 3 (168 Hours).

Q: Which substitute offers the best balance of availability and specification match? A: TLC7528CFNG3 provides exact parametric equivalence with active product status. For cross-manufacturer flexibility, MX7528KP+ offers the tightest INL specification (±0.5 LSB) among Maxim Integrated options while maintaining acceptable settling time for most applications.
