Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC2252AQD is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications for amplifier type, circuit count, output configuration, frequency response, bias characteristics, supply voltage range, temperature rating, and physical package dimensions. The TLC2252AID qualifies as a direct substitute based on complete parameter alignment across these criteria. The primary distinction between the main part and substitute relates to product status and packaging format rather than functional or electrical characteristics.

Key Parameters Determining Substitution:

• Dual-circuit general-purpose amplifier configuration
• Rail-to-rail output capability
• 210 kHz gain bandwidth product
• 0.12 V/µs slew rate
• 4.4 V to 16 V supply voltage range
• -40°C to 125°C operating temperature
• 8-SOIC surface mount package (3.90mm width)
• LinCMOS™ series architecture

Engineering Selection Recommendations

The TLC2252AID is the manufacturer-recommended substitute for the obsolete TLC2252AQD. Both components are manufactured by Texas Instruments and maintain complete electrical and mechanical equivalence across all specified parameters. The TLC2252AID offers the advantage of Active product status, ensuring continued availability and manufacturer support. Both parts comply with ROHS3 and maintain REACH Unaffected status, satisfying environmental and regulatory requirements.

The TLC2252AID features improved moisture sensitivity characteristics (MSL 1 with unlimited shelf life) compared to the TLC2252AQD (MSL 2 with 1-year shelf life), providing enhanced reliability for long-term storage and supply chain management. The substitute part is supplied in Tube packaging format, which may differ from the original part's packaging specification but does not affect functional or electrical performance.

For applications requiring the TLC2252AQD, direct substitution with the TLC2252AID is supported without circuit modification, PCB redesign, or performance degradation. Both components operate identically within the specified electrical and thermal parameters.

Frequently Asked Questions (FAQ)

Q: Can the TLC2252AID be used as a direct replacement for the TLC2252AQD in existing designs?

A: Yes. The TLC2252AID is electrically and mechanically equivalent to the TLC2252AQD across all specified parameters. No circuit modifications or PCB changes are required for substitution.

Q: What is the primary reason for substituting the TLC2252AQD?

A: The TLC2252AQD is classified as Obsolete, indicating discontinued production. The TLC2252AID is an Active product with ongoing manufacturer support and availability, making it the appropriate choice for new designs and long-term supply continuity.

Q: Are there differences in packaging between the TLC2252AQD and TLC2252AID?

A: Both components use the 8-SOIC surface mount package with identical physical dimensions (0.154" width, 3.90mm). The TLC2252AID is supplied in Tube packaging format. The package footprint and pinout are identical, requiring no PCB modifications.

Q: Do both parts meet the same compliance and regulatory standards?

A: Yes. Both the TLC2252AQD and TLC2252AID are ROHS3 Compliant and REACH Unaffected. Both operate across the identical temperature range of -40°C to 125°C and support automotive-grade applications.

Q: What is the difference in Moisture Sensitivity Level (MSL) between these parts?

A: The TLC2252AQD has MSL 2 with a 1-year shelf life, while the TLC2252AID has MSL 1 with unlimited shelf life. This indicates the TLC2252AID has superior moisture resistance and longer storage capability without requiring special handling.

Q: Are the electrical specifications identical between both parts?

A: Yes. Both parts maintain identical specifications for slew rate (0.12 V/µs), gain bandwidth product (210 kHz), input bias current (1 pA), input offset voltage (200 µV), supply current (80 µA per dual channels), output current (50 mA per channel), and supply voltage range (4.4 V to 16 V).
