Engineering Selection Recommendations

TLC072AIDR (Texas Instruments)

The TLC072AIDR is the primary recommended substitute for the discontinued TLC072AIDRG4. This part maintains identical electrical specifications, including slew rate (19 V/µs), gain bandwidth product (10 MHz), input bias current (1.5 pA), and input offset voltage (390 µV). The package footprint is identical (8-SOIC, 0.154", 3.90mm width), enabling direct board-level substitution without layout modifications. The TLC072AIDR carries Active product status, ensuring long-term availability and supply chain continuity. Both parts share identical supply voltage range (4.5 V to 16 V), operating temperature range (-40°C to 125°C), and compliance certifications (ROHS3, MSL Level 1). This substitute requires no circuit redesign or performance validation.

MC33078DR2G (onsemi)

The MC33078DR2G is a functionally compatible alternative for applications where enhanced performance characteristics are acceptable. This device provides a higher gain bandwidth product (16 MHz versus 10 MHz) and superior input offset voltage (150 µV versus 390 µV). The package footprint is identical to the main part (8-SOIC, 0.154", 3.90mm width). However, the MC33078DR2G exhibits lower slew rate (7 V/µs versus 19 V/µs) and higher input bias current (300 nA versus 1.5 pA). The minimum supply voltage requirement is 10 V, which exceeds the TLC072AIDRG4 minimum of 4.5 V. Operating temperature range is limited to -40°C to 85°C. This substitute is suitable for applications operating within the MC33078DR2G supply and temperature specifications.

LM4565F-GE2 (Rohm Semiconductor)

The LM4565F-GE2 provides a general-purpose dual operational amplifier with extended supply voltage range (4 V to 36 V) and significantly higher output current per channel (160 mA versus 57 mA). The package is 8-SOP (0.173", 4.40mm width), which differs from the 8-SOIC footprint of the main part, requiring board layout modification. The LM4565F-GE2 exhibits lower slew rate (5 V/µs) and higher input bias current (70 nA). Operating temperature range is limited to -40°C to 85°C. This substitute is applicable for designs requiring higher output current capability and extended supply voltage range, provided board layout can accommodate the different package dimensions.

Frequently Asked Questions (FAQ)

Q: Can the TLC072AIDR be used as a direct replacement for the TLC072AIDRG4 without circuit modifications?

A: Yes. The TLC072AIDR is electrically and mechanically identical to the TLC072AIDRG4. Both devices share the same slew rate (19 V/µs), gain bandwidth product (10 MHz), input bias current (1.5 pA), input offset voltage (390 µV), supply voltage range (4.5 V to 16 V), operating temperature range (-40°C to 125°C), and 8-SOIC package footprint (0.154", 3.90mm width). No circuit redesign or board layout modification is required.

Q: What are the key differences between the MC33078DR2G and the TLC072AIDRG4?

A: The MC33078DR2G differs in the following parameters: slew rate is lower (7 V/µs versus 19 V/µs), gain bandwidth product is higher (16 MHz versus 10 MHz), input bias current is higher (300 nA versus 1.5 pA), input offset voltage is lower (150 µV versus 390 µV), and minimum supply voltage is higher (10 V versus 4.5 V). The package footprint is identical (8-SOIC, 0.154", 3.90mm width). Operating temperature range is limited to -40°C to 85°C.

Q: Is the LM4565F-GE2 package compatible with the TLC072AIDRG4 board layout?

A: No. The LM4565F-GE2 uses an 8-SOP package (0.173", 4.40mm width), while the TLC072AIDRG4 uses an 8-SOIC package (0.154", 3.90mm width). Although both are 8-pin surface mount packages, the different widths require board layout modification. Footprint adaptation or redesign is necessary for physical compatibility.

Q: Which substitute part is recommended for applications requiring the lowest input bias current?

A: The TLC072AIDR maintains the lowest input bias current at 1.5 pA, identical to the TLC072AIDRG4. The MC33078DR2G exhibits 300 nA input bias current, and the LM4565F-GE2 exhibits 70 nA input bias current. For applications prioritizing minimal input bias current, the TLC072AIDR is the appropriate selection.

Q: Can the LM4565F-GE2 be used in applications requiring operation at 2 V supply voltage?

A: No. The LM4565F-GE2 minimum supply voltage is 4 V. The TLC072AIDRG4 and TLC072AIDR both support operation at 4.5 V minimum. If operation below 4 V is required, neither the LM4565F-GE2 nor the MC33078DR2G are suitable alternatives.

Q: What is the maximum operating temperature for the MC33078DR2G and LM4565F-GE2?

A: Both the MC33078DR2G and LM4565F-GE2 have a maximum operating temperature of 85°C. The TLC072AIDRG4 and TLC072AIDR support operation up to 125°C. For applications requiring operation above 85°C, only the TLC072AIDR is suitable.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The TLC072AIDR, MC33078DR2G, and LM4565F-GE2 are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the compliance status of the TLC072AIDRG4.

Q: Which substitute provides the highest output current per channel?

A: The LM4565F-GE2 provides the highest output current per channel at 160 mA, compared to 57 mA for the TLC072AIDRG4, 57 mA for the TLC072AIDR, and 37 mA for the MC33078DR2G. Selection of the LM4565F-GE2 is appropriate for applications requiring higher output drive capability.
