TLC272CD Equivalent & Substitute Parts
Part Overview
The TLC272CD is a CMOS dual-channel operational amplifier manufactured by Texas Instruments in 8-SOIC surface mount packaging. This device is classified as obsolete, which necessitates identification of active equivalent and substitute components for ongoing production and maintenance applications. The TLC272CD operates across a 3V to 16V supply range with low input bias current (0.7 pA) and moderate slew rate (5.3V/µs), making it suitable for precision analog signal conditioning applications requiring low power consumption.

Engineering Selection Recommendations
Tier 1 - Direct Replacement (Recommended):
TLC272CDR is the primary recommended substitute. This part is manufactured by Texas Instruments and maintains identical electrical specifications to the TLC272CD across all critical parameters: 5.3V/µs slew rate, 2.2 MHz gain bandwidth product, 0.7 pA input bias current, and 1.1 mV input offset voltage. The TLC272CDR is active product status with ROHS3 compliance and unlimited moisture sensitivity rating. Packaging is 8-SOIC surface mount with 105,100 units in stock, ensuring supply continuity.
Tier 2 - Functional Equivalents (STMicroelectronics TS272 Series):
The TS272ACDT, TS272AIDT, TS272BIDT, TS272CDT, and TS272IDT are active CMOS dual-channel amplifiers in 8-SOIC packaging. These parts exceed the TLC272CD electrical specifications with 5.5V/µs slew rate and 3.5 MHz gain bandwidth product. Supply current is reduced to 1 mA per channel (versus 1.9 mA), and output current capability is increased to 45 mA. Temperature range variants include 0°C to 70°C (TS272ACDT, TS272CDT) and -40°C to 125°C (TS272AIDT, TS272BIDT, TS272IDT). Input offset voltage variants range from 0.25 mV to 1.1 mV. All parts are ROHS3 compliant with MSL 1 rating.
Tier 3 - Low-Power Variants (STMicroelectronics TS27L2 Series):
The TS27L2ACDT, TS27L2AIDT, and TS27L2BIDT are ultra-low-power CMOS dual-channel amplifiers designed for battery-powered and energy-constrained applications. These parts feature 0.04V/µs slew rate, 100 kHz gain bandwidth product, and 10 µA supply current per channel. These specifications represent a significant departure from the TLC272CD performance envelope and are suitable only for applications where bandwidth and slew rate requirements are substantially lower than the original design.
Tier 4 - General Purpose Alternative (Obsolete):
LM432MA/NOPB is a general-purpose dual-channel amplifier with 1 MHz gain bandwidth product and 3 nA input bias current. This part is obsolete and not recommended for new designs. The 150 µA supply current per channel and lower bandwidth make it unsuitable as a direct replacement for the TLC272CD.
Compliance and Certification:
All recommended substitute parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 (unlimited) moisture sensitivity rating, matching the TLC272CD environmental and regulatory requirements.
Frequently Asked Questions (FAQ)
Q1: Can TLC272CDR be used as a direct drop-in replacement for TLC272CD?
A: Yes. TLC272CDR is manufactured by Texas Instruments with identical electrical specifications across all parameters: slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current, and supply voltage range. Both parts use 8-SOIC surface mount packaging. The primary difference is product status: TLC272CDR is active with high inventory availability, while TLC272CD is obsolete.
Q2: What are the key differences between TLC272CDR and TS272 series substitutes?
A: TLC272CDR maintains exact electrical parity with TLC272CD. The TS272 series (TS272ACDT, TS272AIDT, TS272BIDT, TS272CDT, TS272IDT) from STMicroelectronics offers enhanced performance: higher slew rate (5.5V/µs versus 5.3V/µs), higher gain bandwidth product (3.5 MHz versus 2.2 MHz), lower supply current (1 mA versus 1.9 mA per channel), and higher output current capability (45 mA versus 30 mA). These improvements are backward compatible for applications designed around TLC272CD specifications.
Q3: Are TS27L2 series parts suitable replacements for TLC272CD?
A: TS27L2 series parts are not suitable direct replacements. These ultra-low-power variants feature significantly reduced bandwidth (100 kHz versus 2.2 MHz) and slew rate (0.04V/µs versus 5.3V/µs). They are designed for ultra-low-power applications where bandwidth requirements are substantially lower. Use TS27L2 series only if your application can tolerate these reduced performance specifications.
Q4: What is the difference between temperature range variants in the TS272 series?
A: TS272ACDT and TS272CDT operate across 0°C to 70°C. TS272AIDT, TS272BIDT, and TS272IDT operate across -40°C to 125°C. Select the temperature range variant based on your application's operating environment. Extended temperature range parts (-40°C to 125°C) are suitable for industrial and automotive applications.
Q5: What is the difference between input offset voltage variants in the TS272 series?
A: TS272ACDT and TS272CDT feature 1.1 mV input offset voltage (matching TLC272CD). TS272AIDT and TS272IDT feature 1.1 mV input offset voltage. TS272BIDT features 0.25 mV input offset voltage, providing superior precision for applications requiring tighter DC accuracy. Select based on your application's input offset voltage tolerance requirements.
Q6: Are all substitute parts ROHS3 compliant?
A: Yes. All recommended substitute parts (TLC272CDR, TS272 series, TS27L2 series) are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating, matching the TLC272CD environmental compliance profile.
Q7: What packaging options are available for substitute parts?
A: All substitute parts use 8-SOIC (0.154", 3.90mm width) surface mount packaging, matching the TLC272CD package footprint. Packaging formats vary: TLC272CDR is available in Cut Tape (CT) & Digi-Reel®; TS272 series parts are available in Cut Tape (CT) & Digi-Reel® or Tape & Reel (TR); TS27L2 series parts are available in Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel®. Verify packaging availability with your supplier for your specific procurement requirements.
Q8: Which substitute part offers the best inventory availability?
A: TLC272CDR offers the highest inventory availability with 105,100 units in stock. TS272 series parts range from 1,457 to 25,400 units in stock. TS27L2 series parts range from 3,120 to 10,400 units in stock. For immediate availability, TLC272CDR is the optimal choice.
