Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC072CDG4 is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Amplifier type (general purpose)
• Number of circuits (2)
• Gain bandwidth product (10 MHz minimum)
• Supply voltage range (must encompass or exceed 4.5V to 16V)
• Input bias current (lower values acceptable)
• Output current capability (57 mA minimum per channel)

Mechanical Compatibility Criteria:

• Surface mount package type (8-SOIC or equivalent footprint)
• Package width tolerance (3.90mm nominal)

Compliance & Status Criteria:

• RoHS3 compliance
• Active product status (preferred for long-term availability)
• MSL rating of 1 (unlimited moisture sensitivity)

The substitute parts listed below meet these criteria with varying degrees of parameter overlap. TLC072CD represents a direct electrical equivalent with identical specifications but active product status. MC33078DR2G, LM4565F-GE2, and SE5532AD8R2G provide functional substitution with enhanced or alternative performance characteristics suitable for the general-purpose amplifier category.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TLC072CD

The TLC072CD is the recommended direct substitute for the obsolete TLC072CDG4. This part maintains identical electrical specifications including slew rate (19V/µs), gain bandwidth product (10 MHz), input bias current (1.5 pA), and supply voltage range (4.5V to 16V). The TLC072CD is manufactured by Texas Instruments with active product status, ensuring long-term availability and supply chain continuity. Both parts share the same 8-SOIC package footprint (0.154", 3.90mm width) and are pin-compatible. The only difference is packaging format (tube versus surface mount reel), which does not affect electrical performance or PCB integration.

Secondary Substitutes: MC33078DR2G, SE5532AD8R2G, LM4565F-GE2

These alternatives provide functional substitution for general-purpose amplifier applications with active product status and extended operating temperature ranges (-40°C to 85°C or -55°C to 125°C). All three maintain the 2-circuit configuration and 8-SOIC package format required for mechanical compatibility.

MC33078DR2G (onsemi) offers enhanced gain bandwidth product (16 MHz) and improved input offset voltage (150 µV) but operates with a minimum supply voltage of 10V, which exceeds the TLC072CDG4 minimum of 4.5V. This part is suitable for applications where the higher minimum supply voltage is not a constraint.

SE5532AD8R2G (onsemi) extends the operating temperature range to -55°C to 125°C and supports supply voltages up to 40V, making it suitable for industrial and extended-temperature applications. Higher supply current (8 mA) should be considered in power-budget-constrained designs.

LM4565F-GE2 (Rohm Semiconductor) provides the highest output current capability (160 mA per channel) and operates across 4V to 36V supply range. The package width (0.173", 4.40mm) differs slightly from the TLC072CDG4 (0.154", 3.90mm), requiring PCB layout verification for footprint compatibility.

All substitute parts carry ROHS3 compliance, MSL rating of 1, and active product status, supporting regulatory and supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Can TLC072CD be used as a direct replacement for TLC072CDG4 without circuit modifications?

A: Yes. The TLC072CD is electrically and mechanically identical to the TLC072CDG4. Both parts share the same pin configuration, electrical specifications, and 8-SOIC package footprint. The only difference is packaging format (tube versus reel), which does not affect circuit performance or PCB assembly compatibility.

Q: What is the key difference between TLC072CDG4 and MC33078DR2G?

A: The MC33078DR2G has a higher gain bandwidth product (16 MHz versus 10 MHz) and lower input offset voltage (150 µV versus 390 µV), providing improved frequency response and precision. However, the MC33078DR2G requires a minimum supply voltage of 10V, whereas the TLC072CDG4 operates from 4.5V. Applications using lower supply voltages must use TLC072CD or SE5532AD8R2G instead.

Q: Is the LM4565F-GE2 package compatible with TLC072CDG4 PCB layouts?

A: The LM4565F-GE2 uses an 8-SOIC package with a width of 0.173" (4.40mm), compared to the TLC072CDG4 width of 0.154" (3.90mm). While both are 8-SOIC packages, the footprint difference requires PCB layout verification. Consult the manufacturer datasheets for exact pin spacing and land pattern specifications before substitution.

Q: Which substitute part supports the widest operating temperature range?

A: The SE5532AD8R2G supports the widest operating temperature range of -55°C to 125°C, compared to the TLC072CDG4 range of 0°C to 70°C. This makes SE5532AD8R2G suitable for industrial, automotive, and extended-temperature applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (TLC072CD, MC33078DR2G, LM4565F-GE2, and SE5532AD8R2G) are ROHS3 compliant with MSL rating of 1 (unlimited moisture sensitivity), meeting regulatory requirements for lead-free and hazardous substance restrictions.

Q: What is the impact of higher supply current in SE5532AD8R2G compared to TLC072CDG4?

A: The SE5532AD8R2G draws 8 mA total supply current, compared to 2.1 mA for the TLC072CDG4. In power-constrained applications, this increased current consumption may require larger power supply capacity or additional power management considerations. Verify power budget compatibility before substitution.

Q: Can MC33078DR2G be used in applications requiring 4.5V supply voltage?

A: No. The MC33078DR2G has a minimum supply voltage specification of 10V and cannot operate reliably at 4.5V. For low-voltage applications (4.5V to 16V), use TLC072CD or LM4565F-GE2 instead.

Q: What is the significance of input bias current differences among substitute parts?

A: The TLC072CDG4 and TLC072CD have extremely low input bias current (1.5 pA), suitable for high-impedance input circuits. Substitute parts MC33078DR2G and SE5532AD8R2G have higher input bias current (300 nA), which may introduce additional input offset errors in high-impedance applications. LM4565F-GE2 offers intermediate performance (70 nA). Select based on input impedance requirements and acceptable offset error specifications.
