Substitute Part Grouping Explanation

Substitution of the TL712CDG4 is determined by strict equivalence across the following critical parameters:

• Differential Comparator Type: Single element differential configuration
• Output Configuration: Complementary, push-pull, tri-state TTL output
• Supply Voltage Range: 4.75V ~ 5.25V
• Quiescent Current: 20mA maximum
• Propagation Delay: 25ns maximum
• Hysteresis: 5mV
• Operating Temperature Range: 0°C ~ 70°C
• Package: 8-SOIC surface mount
• Compliance: ROHS3 compliant, MSL 1

The TL712CD is identified as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is product status: TL712CDG4 is obsolete while TL712CD is active, with improved inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The TL712CD is the direct active equivalent for the obsolete TL712CDG4. Both parts maintain identical electrical and mechanical specifications, with the TL712CD offering the advantage of active product status and higher inventory availability (1900 pcs vs. 875 pcs). Both parts are ROHS3 compliant and carry MSL 1 rating, ensuring compatibility with standard manufacturing and storage protocols. Selection between these parts should be based on procurement availability and supply chain requirements rather than technical performance, as electrical characteristics are equivalent.

Frequently Asked Questions (FAQ)

Q: Can TL712CD directly replace TL712CDG4 in existing designs? A: Yes. The TL712CD is electrically and mechanically identical to the TL712CDG4. Pin configuration, package dimensions, and all electrical parameters are equivalent. No design modifications are required.

Q: What is the difference between TL712CDG4 and TL712CD? A: The primary difference is product status. TL712CDG4 is obsolete, while TL712CD is active. The suffix "G4" in TL712CDG4 indicates a specific packaging or date code variant. Electrical specifications and 8-SOIC package dimensions are identical.

Q: Are there any compliance or certification differences? A: No. Both parts carry identical ROHS3 compliance and MSL 1 moisture sensitivity ratings. Both are suitable for standard PCB assembly and storage conditions.

Q: What is the significance of the 8-SOIC package specification? A: The 8-SOIC (Small Outline Integrated Circuit) package specifies the physical form factor with 0.154" width and 3.90mm body width. This ensures mechanical compatibility with existing PCB layouts and automated assembly equipment. Both parts use identical package specifications.

Q: Why is the TL712CDG4 listed as obsolete? A: Product obsolescence typically results from manufacturer discontinuation decisions. The TL712CD remains in active production, making it the recommended choice for new procurement and long-term supply chain stability.
