Engineering Selection Recommendations

TL072CPSR (Texas Instruments) Recommended as the primary substitute for TL072CPSRG4. This part maintains identical electrical specifications and operating temperature range. The primary difference is packaging format (Cut Tape & Digi-Reel® versus Tape & Reel). Product status is Last Time Buy, consistent with the main part. Inventory availability is significantly higher at 5,249 pieces. Selection is appropriate for applications requiring exact electrical parameter matching and standard operating temperature range (0°C ~ 70°C).

TL072IDR (Texas Instruments) Recommended as a secondary substitute with enhanced specifications. This part offers higher gain bandwidth product (5.25 MHz versus 3 MHz) and extended operating temperature range (-40°C ~ 85°C). Product status is Active, indicating ongoing availability. Package dimensions differ (0.154" versus 0.209" width), requiring PCB layout verification. Inventory is substantially higher at 35,200 pieces. Selection is appropriate for applications requiring extended temperature operation or higher bandwidth performance.

MC33172D and MC33172DT (STMicroelectronics) Recommended as alternative substitutes for applications with relaxed slew rate and gain bandwidth requirements. These parts offer broader supply voltage range (4 V to 44 V) and extended operating temperature (-40°C ~ 105°C). Input bias current is higher (20 nA versus 65 pA), and slew rate is lower (2 V/µs versus 13 V/µs). Product status is Active with high inventory availability. Selection is appropriate for general-purpose amplifier applications where J-FET input characteristics are not critical and lower power consumption is beneficial.

Frequently Asked Questions (FAQ)

Q: Can TL072CPSR be used as a direct replacement for TL072CPSRG4? A: Yes. TL072CPSR provides identical electrical specifications and operating temperature range. The difference is packaging format (Cut Tape & Digi-Reel® versus Tape & Reel). Verify that your assembly process accommodates the packaging format change.

Q: What is the primary difference between TL072IDR and TL072CPSRG4? A: TL072IDR offers higher gain bandwidth product (5.25 MHz versus 3 MHz) and extended operating temperature range (-40°C ~ 85°C versus 0°C ~ 70°C). Package width is smaller (0.154" versus 0.209"), requiring PCB layout verification. Product status is Active, ensuring continued availability.

Q: Are MC33172D and MC33172DT suitable replacements for J-FET applications? A: MC33172D and MC33172DT are General Purpose amplifiers, not J-FET input devices. They are suitable only if your application does not require J-FET input characteristics. These parts offer lower input bias current (20 nA versus 65 pA) and lower slew rate (2 V/µs versus 13 V/µs). Verify application requirements before selection.

Q: What is the impact of package width differences between 0.209" and 0.154"? A: Package width affects PCB footprint and board layout. The 0.154" width (TL072IDR, MC33172D, MC33172DT) is more compact than the 0.209" width (TL072CPSRG4, TL072CPSR). Verify PCB design compatibility before substitution. Pin configuration remains identical for all 8-SOIC variants.

Q: Why is TL072CPSRG4 classified as Last Time Buy? A: Last Time Buy status indicates the manufacturer has discontinued production. This classification necessitates identification of substitute parts for future supply requirements. TL072CPSR and TL072IDR are recommended alternatives from the same manufacturer.

Q: What is the significance of RoHS3 compliance for all listed parts? A: All parts are ROHS3 Compliant, confirming compliance with Restriction of Hazardous Substances regulations. This certification is maintained across all substitute options, ensuring regulatory compatibility for applications subject to RoHS requirements.

Q: Can I use MC33172DT instead of TL072CPSRG4 in a high-speed signal processing application? A: MC33172DT has lower slew rate (2 V/µs versus 13 V/µs) and lower gain bandwidth product (2.1 MHz versus 3 MHz). Selection depends on specific application bandwidth and slew rate requirements. Verify that your application tolerates these performance reductions before substitution.

Q: What inventory considerations should guide part selection? A: TL072CPSRG4 has 855 pieces in stock (Last Time Buy status). TL072CPSR has 5,249 pieces. TL072IDR has 35,200 pieces. MC33172D has 100,400 pieces. MC33172DT has 45,300 pieces. For long-term supply security, TL072IDR, MC33172D, or MC33172DT are preferred due to Active product status and higher inventory levels.
