Engineering Selection Recommendations

TL972IPWR (Texas Instruments)

The TL972IPWR is the direct active equivalent of the TL972IPW. This part maintains identical electrical specifications across all critical parameters: 12 MHz gain bandwidth product, 5V/µs slew rate, 200 nA input bias current, and 80 mA output current per channel. The TL972IPWR carries Active product status with significantly higher inventory availability (20,239 units in stock versus 1,900 for the obsolete TL972IPW). Both parts share identical supply voltage range (2.7V to 12V), operating temperature span (-40°C to 125°C), and 8-TSSOP package specifications. RoHS3 compliance and MSL Level 1 rating are maintained. The primary difference is packaging format: TL972IPWR is supplied in Cut Tape and Digi-Reel formats, whereas TL972IPW was supplied in Tray format. This part is the recommended primary substitute for direct replacement applications.

TS972IPT (STMicroelectronics)

The TS972IPT provides functional equivalence as a general purpose dual operational amplifier in 8-TSSOP package with rail-to-rail output. This part matches the TL972IPW across amplifier type, circuit count, output configuration, and package geometry. Electrical performance is comparable: 12 MHz gain bandwidth product, 200 nA input bias current, and 1 mV input offset voltage. The TS972IPT delivers superior output current capability (100 mA per channel versus 80 mA), though slew rate is slightly reduced (4V/µs versus 5V/µs). Operating temperature range extends to -40°C to 125°C, matching the TL972IPW. Maximum supply voltage is limited to 10V (versus 12V for TL972IPW), which may restrict applications requiring higher supply rails. The TS972IPT carries AEC-Q100 automotive qualification and Automotive grade designation. This part is suitable for applications where automotive-grade components are required or where the reduced maximum supply voltage does not conflict with system design.

OP262DRUZ-REEL (Analog Devices Inc.)

The OP262DRUZ-REEL is a general purpose dual operational amplifier in 8-TSSOP package with rail-to-rail output. This part satisfies primary substitution criteria: dual circuits, general purpose amplifier type, rail-to-rail output, identical package and mounting specifications, and full operating temperature range (-40°C to 125°C). The OP262DRUZ-REEL demonstrates enhanced performance in specific parameters: 13V/µs slew rate (versus 5V/µs) and 15 MHz gain bandwidth product (versus 12 MHz). However, this part exhibits trade-offs in other parameters: input bias current of 260 nA (versus 200 nA), input offset voltage of 800 µV (versus 1 mV), and reduced output current of 30 mA per channel (versus 80 mA). Supply current consumption is significantly lower at 550 µA for dual channels (versus 2 mA). The OP262DRUZ-REEL is suitable for applications prioritizing speed and low power consumption where reduced output current capability does not present a constraint.

OP279GRUZ-REEL (Analog Devices Inc.)

The OP279GRUZ-REEL is a buffer amplifier (not general purpose) in 8-TSSOP package with rail-to-rail output. While this part shares identical package geometry and mounting type, it does not satisfy primary substitution criteria due to functional classification as a buffer amplifier rather than general purpose amplifier. Additionally, the OP279GRUZ-REEL exhibits significant parameter deviations: maximum operating temperature of 85°C (versus 125°C), minimum supply voltage of 4.5V (versus 2.7V), reduced slew rate of 3V/µs (versus 5V/µs), reduced gain bandwidth product of 5 MHz (versus 12 MHz), and reduced output current of 50 mA per channel (versus 80 mA). This part is not recommended as a substitute for the TL972IPW in general purpose amplifier applications.

Frequently Asked Questions (FAQ)

Q: Can TL972IPWR be used as a direct replacement for TL972IPW?

A: Yes. The TL972IPWR is the active equivalent of the obsolete TL972IPW. Both parts share identical electrical specifications, supply voltage range, operating temperature span, and 8-TSSOP package configuration. The only difference is packaging format (Cut Tape/Digi-Reel versus Tray). TL972IPWR is the recommended substitute for new designs and production continuity.

Q: What are the key differences between TL972IPW and TS972IPT?

A: Both parts are general purpose dual operational amplifiers with identical 12 MHz gain bandwidth product and 200 nA input bias current. The TS972IPT offers higher output current (100 mA versus 80 mA per channel) but has slightly lower slew rate (4V/µs versus 5V/µs) and reduced maximum supply voltage (10V versus 12V). The TS972IPT carries automotive qualification (AEC-Q100), making it suitable for automotive applications where the TL972IPW is not qualified.

Q: Why is OP262DRUZ-REEL not a direct equivalent despite being a dual general purpose amplifier?

A: While OP262DRUZ-REEL is a general purpose dual amplifier in the same package, it exhibits significant performance trade-offs. Output current is reduced to 30 mA per channel (versus 80 mA), which may be insufficient for applications requiring higher drive capability. Conversely, slew rate and gain bandwidth product are enhanced. Applications requiring 80 mA output current per channel cannot use OP262DRUZ-REEL without circuit redesign.

Q: Can OP279GRUZ-REEL substitute for TL972IPW?

A: No. OP279GRUZ-REEL is classified as a buffer amplifier, not a general purpose amplifier, and does not satisfy primary substitution criteria. Additionally, it has restricted operating temperature range (-40°C to 85°C versus -40°C to 125°C), higher minimum supply voltage (4.5V versus 2.7V), and significantly reduced performance specifications. This part is not suitable for TL972IPW replacement.

Q: What packaging formats are available for substitute parts?

A: TL972IPWR, OP262DRUZ-REEL, OP279GRUZ-REEL, and TS972IPT are all supplied in Cut Tape (CT) and Digi-Reel formats. The original TL972IPW was supplied in Tray format. All parts use identical 8-TSSOP surface mount package geometry and are compatible with standard PCB assembly processes.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. TL972IPWR, OP262DRUZ-REEL, OP279GRUZ-REEL, and TS972IPT all carry RoHS3 compliance certification. All parts have MSL Level 1 (Unlimited) moisture sensitivity rating, indicating no special moisture control requirements during storage or handling.

Q: Which substitute part has the highest inventory availability?

A: TL972IPWR has the highest inventory with 20,239 units in stock, followed by TS972IPT with 17,850 units. OP262DRUZ-REEL has 5,269 units, and OP279GRUZ-REEL has 1,645 units. For supply chain continuity, TL972IPWR is the preferred choice.

Q: What is the maximum supply voltage for each substitute part?

A: TL972IPWR and OP262DRUZ-REEL support 12V maximum supply voltage, matching the TL972IPW. TS972IPT is limited to 10V maximum supply voltage. OP279GRUZ-REEL also supports 12V maximum. Applications requiring supply voltages between 10V and 12V cannot use TS972IPT without circuit modification.
