Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL972ID is determined by strict electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Dual-circuit (2 circuits) general-purpose operational amplifier architecture
• Rail-to-rail output configuration
• Supply voltage range encompassing 2.7V minimum and 12V maximum
• Operating temperature range of -40°C to 125°C
• Input bias current, input offset voltage, slew rate, and gain-bandwidth product within acceptable application tolerances
• Output current capability sufficient for load requirements

Mechanical Compatibility Criteria:

• 8-pin surface-mount package (8-SOIC or equivalent compact form factor)
• Pin-compatible footprint allowing direct PCB substitution without layout modification

Compliance Requirements:

• ROHS3 compliance for environmental standards
• Moisture Sensitivity Level 1 for handling and storage compatibility

Substitute parts are grouped into two categories: Direct Pin-Compatible Substitutes (identical 8-SOIC package) and Functional Equivalents (alternative compact packages with electrical equivalence).

Parameter Comparison

Engineering Selection Recommendations

TL972IDR (Texas Instruments)

The TL972IDR is the primary recommended substitute for the TL972ID. Both parts share identical electrical specifications, including 5V/µs slew rate, 12 MHz gain-bandwidth product, 200 nA input bias current, and 80 mA output current per channel. The TL972IDR maintains the same 8-SOIC package footprint and operates across the identical 2.7V to 12V supply range. The critical distinction is product status: TL972IDR is Active with 35,100 pieces in stock, compared to the TL972ID's Last Time Buy status with limited inventory. This part provides direct pin-for-pin compatibility and requires no circuit redesign. ROHS3 compliance and MSL 1 rating are maintained.

TS972IDT (STMicroelectronics)

The TS972IDT from STMicroelectronics provides electrical equivalence with minor performance variations. It maintains the dual-circuit, rail-to-rail architecture, 12 MHz gain-bandwidth product, and 200 nA input bias current. The TS972IDT offers superior output current capability at 100 mA per channel compared to the TL972ID's 80 mA. However, the slew rate is reduced to 4V/µs, and the maximum supply voltage is limited to 10V (versus 12V for the TL972ID). The TS972IDT is qualified to AEC-Q100 automotive standards and carries Active product status with 15,604 pieces available. The 8-SOIC package is pin-compatible. This part is suitable for applications where the reduced slew rate and lower maximum supply voltage do not conflict with design requirements.

TS972IST (STMicroelectronics)

The TS972IST is functionally equivalent to the TL972ID but uses an 8-TSSOP/8-MSOP (MiniSO) package instead of 8-SOIC. Electrical specifications are identical to the TS972IDT: 4V/µs slew rate, 12 MHz gain-bandwidth product, 100 mA output current per channel, and 10V maximum supply voltage. This part requires PCB layout modification due to the different package footprint and pin spacing (3.00mm width versus 3.90mm for SOIC). The TS972IST is AEC-Q100 qualified and Active with 25,300 pieces in stock. Selection of this part is appropriate only when PCB redesign is feasible and the reduced slew rate and supply voltage limits are acceptable.

MCP6H92-E/SN (Microchip Technology)

The MCP6H92-E/SN offers enhanced performance characteristics in specific parameters. It features a higher slew rate of 10V/µs and significantly lower input bias current of 10 pA (compared to 200 nA). However, the gain-bandwidth product is reduced to 10 MHz, and the output current per channel is limited to 41 mA. The minimum supply voltage is raised to 3.5V, which may restrict operation in low-voltage applications. The MCP6H92-E/SN maintains 8-SOIC pin compatibility and is Active with 1,513 pieces available. This part is suitable for applications prioritizing low input bias current and higher slew rate over bandwidth and output current.

OP262TRZ-EP-R7 (Analog Devices Inc.)

The OP262TRZ-EP-R7 represents the highest-performance option among substitutes, with 13V/µs slew rate, 15 MHz gain-bandwidth product, and 25 µV input offset voltage. However, it exhibits higher input bias current at 260 nA and significantly reduced output current of 30 mA per channel. Supply current consumption is substantially lower at 650 µA per channel. The OP262TRZ-EP-R7 maintains 8-SOIC package compatibility and extends the operating temperature range to -55°C to 125°C. This part is Active with 998 pieces in stock. Selection is appropriate for precision applications requiring low offset voltage and extended temperature range, provided the reduced output current does not limit load-driving capability.

Frequently Asked Questions (FAQ)

Q1: Can I directly replace TL972ID with TL972IDR without modifying my circuit?

Yes. The TL972IDR is a direct pin-for-pin substitute with identical electrical specifications. No circuit modification is required. Both parts use the 8-SOIC package with the same pinout, supply voltage range (2.7V to 12V), and performance characteristics (5V/µs slew rate, 12 MHz bandwidth, 80 mA output current per channel).

Q2: What is the key difference between TL972IDR and TS972IDT?

The primary differences are: (1) TS972IDT has reduced slew rate (4V/µs versus 5V/µs), (2) TS972IDT has lower maximum supply voltage (10V versus 12V), and (3) TS972IDT has higher output current capability (100 mA versus 80 mA per channel). Both maintain 12 MHz gain-bandwidth product and 200 nA input bias current. TS972IDT is AEC-Q100 automotive qualified.

Q3: Can TS972IST be used as a drop-in replacement for TL972ID?

No. While TS972IST is electrically equivalent to TS972IDT, it uses an 8-TSSOP/8-MSOP package instead of 8-SOIC. The different package footprint and pin spacing (3.00mm versus 3.90mm width) require PCB layout redesign. Direct soldering to an 8-SOIC footprint is not possible.

Q4: Which substitute part has the lowest input bias current?

The MCP6H92-E/SN has the lowest input bias current at 10 pA, compared to 200 nA for TL972ID, TL972IDR, TS972IDT, and TS972IST, and 260 nA for OP262TRZ-EP-R7. This makes MCP6H92-E/SN suitable for high-impedance input applications.

Q5: Are all substitute parts ROHS3 compliant?

Yes. All listed substitute parts (TL972IDR, MCP6H92-E/SN, OP262TRZ-EP-R7, TS972IDT, TS972IST) are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the TL972ID's environmental compliance.

Q6: Which substitute part operates at the lowest supply voltage?

The TL972IDR, TS972IDT, TS972IST, and OP262TRZ-EP-R7 all support minimum supply voltage of 2.7V. The MCP6H92-E/SN has a higher minimum of 3.5V, restricting its use in applications requiring operation below 3.5V.

Q7: What is the maximum supply voltage for each substitute?

TL972IDR, MCP6H92-E/SN, and OP262TRZ-EP-R7 support 12V maximum. TS972IDT and TS972IST are limited to 10V maximum. Applications requiring operation above 10V must use TL972IDR, MCP6H92-E/SN, or OP262TRZ-EP-R7.

Q8: Which substitute has the highest slew rate?

The OP262TRZ-EP-R7 has the highest slew rate at 13V/µs, followed by MCP6H92-E/SN at 10V/µs, TL972IDR at 5V/µs, and TS972IDT/TS972IST at 4V/µs. Higher slew rate is beneficial for fast signal transitions and reduced settling time.

Q9: Which substitute provides the highest output current per channel?

TS972IDT and TS972IST both provide 100 mA output current per channel, compared to 80 mA for TL972IDR and 41 mA for MCP6H92-E/SN. OP262TRZ-EP-R7 provides the lowest at 30 mA per channel.

Q10: Is OP262TRZ-EP-R7 suitable for automotive applications?

OP262TRZ-EP-R7 is not explicitly qualified to AEC-Q100 automotive standards. TS972IDT and TS972IST carry AEC-Q100 qualification. For automotive applications, TS972IDT or TS972IST are the appropriate choices among the listed substitutes.
