Engineering Selection Recommendations

Primary Recommendation: TLC072CDR

The TLC072CDR is the preferred substitute for the obsolete TLC072CDRG4. This part maintains identical electrical specifications across all critical parameters: 19V/µs slew rate, 10 MHz gain bandwidth product, 1.5 pA input bias current, 390 µV input offset voltage, and 57 mA output current per channel. Both devices operate within the 4.5V to 16V supply range and share the same 8-SOIC (3.90mm width) package footprint. The TLC072CDR holds active product status with significantly higher inventory availability (25,300 units), ensuring long-term supply continuity. All regulatory compliance certifications are identical: ROHS3 compliant, MSL 1, REACH unaffected, and EAR99 classification.

Secondary Recommendation: MC33078DR2G

The MC33078DR2G (onsemi) provides an alternative with extended operating temperature range (-40°C to 85°C) and higher maximum supply voltage (36V). This device maintains the 8-SOIC (3.90mm) package and dual-circuit configuration. However, the slew rate is reduced to 7V/µs, and output current per channel is 37 mA. The MC33078DR2G is suitable for applications requiring broader temperature operation or higher supply voltages within the same package footprint.

Tertiary Recommendation: SE5532AD8R2G

The SE5532AD8R2G (onsemi) offers the widest operating temperature range (-55°C to 125°C) and highest maximum supply voltage (40V). It maintains 10 MHz gain bandwidth product and 8-SOIC (3.90mm) packaging. The slew rate is 9V/µs with 38 mA output current per channel. This part is appropriate for extreme temperature environments or applications requiring maximum supply voltage headroom.

Alternative Consideration: LM4565F-GE2

The LM4565F-GE2 (Rohm Semiconductor) provides the highest output current per channel (160 mA) and lowest input bias current (70 nA), with extended supply range (4V to 36V) and operating temperature (-40°C to 85°C). However, this device uses an 8-SOP package with 4.40mm width, requiring PCB layout modification. The slew rate is reduced to 5V/µs. This part is suitable only when PCB redesign is acceptable and higher output current is required.

Frequently Asked Questions (FAQ)

Q1: Can TLC072CDR be used as a direct replacement for TLC072CDRG4 without circuit modification?

A: Yes. The TLC072CDR is electrically and mechanically identical to the TLC072CDRG4. Both devices share the same 8-SOIC (3.90mm width) package, identical pin configuration, and all electrical specifications including slew rate (19V/µs), gain bandwidth product (10 MHz), input bias current (1.5 pA), input offset voltage (390 µV), and output current per channel (57 mA). No circuit modification is required.

Q2: What is the primary reason for substituting the TLC072CDRG4?

A: The TLC072CDRG4 is classified as obsolete. Substitution is necessary to ensure continued design support, production availability, and long-term supply chain reliability. The TLC072CDR provides identical functionality with active product status and superior inventory availability.

Q3: Are all substitute parts ROHS3 compliant and MSL 1?

A: Yes. All identified substitute parts (TLC072CDR, MC33078DR2G, SE5532AD8R2G, and LM4565F-GE2) are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level). All parts are REACH unaffected and classified as EAR99 for export control purposes.

Q4: Which substitute part should be selected for applications requiring extended temperature operation?

A: The SE5532AD8R2G provides the broadest operating temperature range (-55°C to 125°C) and is suitable for extreme temperature environments. The MC33078DR2G offers a more moderate extended range (-40°C to 85°C). Both maintain 8-SOIC (3.90mm) packaging and dual-circuit configuration.

Q5: What is the impact of selecting MC33078DR2G or SE5532AD8R2G on circuit performance?

A: Both alternatives reduce slew rate compared to the original TLC072CDRG4. The MC33078DR2G provides 7V/µs (versus 19V/µs), and the SE5532AD8R2G provides 9V/µs. Output current per channel is also reduced: 37 mA and 38 mA respectively, compared to 57 mA. These reductions are acceptable for general-purpose applications but may impact high-speed or high-current output stages.

Q6: Can LM4565F-GE2 be used without PCB layout changes?

A: No. The LM4565F-GE2 uses an 8-SOP package with 4.40mm width, compared to the 8-SOIC (3.90mm width) of the original TLC072CDRG4. PCB footprint modification is required. This part should be selected only when higher output current (160 mA per channel) justifies redesign effort.

Q7: What packaging options are available for substitute parts?

A: TLC072CDR, MC33078DR2G, and SE5532AD8R2G are all available in 8-SOIC (3.90mm width) surface mount packages, maintaining footprint compatibility with the original TLC072CDRG4. The LM4565F-GE2 is available in 8-SOP (4.40mm width), requiring PCB modification. All substitute parts are available in Cut Tape (CT), Digi-Reel®, or Tape & Reel (TR) packaging formats.

Q8: Which substitute part has the best inventory availability?

A: The TLC072CDR has the highest inventory availability at 25,300 units in stock, followed by MC33078DR2G with 60,100 units. The SE5532AD8R2G has 8,337 units, and LM4565F-GE2 has 2,353 units. For immediate production needs, TLC072CDR or MC33078DR2G are recommended.

Q9: Are there supply voltage compatibility concerns when substituting?

A: The TLC072CDR maintains identical supply voltage range (4.5V to 16V) as the original TLC072CDRG4. The MC33078DR2G, SE5532AD8R2G, and LM4565F-GE2 all support the original 4.5V to 16V range with extended maximums (36V to 40V), providing backward compatibility. No supply voltage circuit modifications are required for any substitute part.

Q10: What is the difference between the TLC072CDRG4 and TLC072CDR part numbers?

A: The TLC072CDRG4 and TLC072CDR share the same base product number (TLC072) and are manufactured by Texas Instruments. The primary difference is product status: TLC072CDRG4 is obsolete, while TLC072CDR is active. The suffix variations indicate different packaging formats (Digi-Reel® for TLC072CDR). Electrical specifications are identical.
