TLC073CDR Equivalent & Substitute Parts

Part Overview

The TLC073CDR is a CMOS dual-channel operational amplifier manufactured by Texas Instruments, packaged in a 14-SOIC surface mount configuration. This device is classified as a Last Time Buy product, indicating discontinued production with limited inventory availability. The TLC073CDR serves applications requiring low-power CMOS amplification with dual-circuit integration in compact form factors. Due to its Last Time Buy status, identifying functionally equivalent substitute parts is essential for design continuity and long-term supply chain planning.

Substitute Part Grouping Explanation

Substitution of the TLC073CDR is determined by strict equivalence across core electrical and mechanical parameters. The substitute part TLC073IDGQR maintains identical electrical specifications including slew rate (19 V/µs), gain bandwidth product (10 MHz), input bias current (1.5 pA), input offset voltage (390 µV), supply current (2.1 mA per dual channels), and output current per channel (57 mA). Both parts operate across the same supply voltage range (4.5 V to 16 V minimum and maximum respectively) and share the same base product number (TLC073), confirming functional equivalence at the circuit level.

The primary distinction between these parts lies in packaging format and operational temperature range. The TLC073CDR uses a 14-SOIC package with a commercial temperature range (0°C to 70°C), while the TLC073IDGQR employs a 10-HVSSOP package with an extended automotive temperature range (−40°C to 125°C) and carries AEC-Q100 automotive qualification. Both devices maintain identical RoHS3 compliance, unlimited moisture sensitivity level (MSL 1), and REACH unaffected status.

Substitution is valid when the following conditions are met:

• Electrical specifications match across all amplifier parameters
• Supply voltage requirements are compatible
• Package footprint and pin configuration accommodate board-level integration
• Operating temperature requirements of the application fall within the substitute part's rated range
• Compliance certifications meet or exceed application requirements

Parameter Comparison

Engineering Selection Recommendations

The TLC073IDGQR serves as a direct functional substitute for the TLC073CDR based on electrical parameter equivalence. Selection between these parts depends on application-specific requirements:

Use TLC073CDR when:

• Existing inventory of Last Time Buy stock is available and cost optimization is prioritized
• The 14-SOIC package footprint is already integrated into current PCB designs
• Operating temperature requirements remain within the 0°C to 70°C commercial range
• No automotive qualification is required

Use TLC073IDGQR when:

• Long-term supply continuity is required, as this part maintains Active product status
• Extended temperature operation (−40°C to 125°C) is necessary for the application
• Automotive-grade reliability (AEC-Q100 qualified) is mandated by design specifications
• The 10-HVSSOP package footprint can be accommodated in new or revised PCB layouts
• Higher inventory availability (5624 pcs vs. 1169 pcs) supports production scheduling

Both parts maintain identical electrical performance and regulatory compliance (ROHS3, REACH unaffected). The substitute part offers superior long-term availability and extended operational range, making it the preferred choice for new designs or production continuity planning.

Frequently Asked Questions (FAQ)

Q: Are the TLC073CDR and TLC073IDGQR electrically interchangeable?

A: Yes. Both parts share identical electrical specifications including slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, and output current. They operate across the same supply voltage range (4.5 V to 16 V) and deliver equivalent amplification performance in dual-channel CMOS configurations.

Q: What is the primary difference between these two parts?

A: The main differences are packaging format and temperature rating. The TLC073CDR uses a 14-SOIC package with a commercial temperature range (0°C to 70°C), while the TLC073IDGQR uses a 10-HVSSOP package with an automotive temperature range (−40°C to 125°C) and AEC-Q100 qualification. The TLC073IDGQR also maintains Active product status, whereas the TLC073CDR is Last Time Buy.

Q: Can I use the TLC073IDGQR as a direct replacement on a PCB designed for the TLC073CDR?

A: Direct PCB replacement requires layout modification. The 14-SOIC package (0.154" width) and 10-HVSSOP package (0.118" width) have different footprints and pin configurations. A new PCB layout or adapter solution is necessary to accommodate the TLC073IDGQR. Verify pin-to-pin compatibility and signal routing before implementation.

Q: Which part should I specify for a new design?

A: The TLC073IDGQR is recommended for new designs. It offers Active product status ensuring long-term availability, extended temperature operation suitable for diverse environments, automotive-grade qualification for reliability-critical applications, and higher inventory levels supporting production schedules.

Q: Are both parts RoHS compliant?

A: Yes. Both the TLC073CDR and TLC073IDGQR are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for commercial and industrial applications.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without moisture-related degradation concerns. Standard handling and storage practices apply.

Q: Why is the TLC073CDR marked as Last Time Buy?

A: Last Time Buy status indicates Texas Instruments has discontinued production of this part number. Existing inventory is available for purchase, but no future production runs are planned. The TLC073IDGQR represents the active continuation of this product line.
