Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC272BCPS is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Amplifier type (CMOS vs. General Purpose)
• Number of circuits (dual-channel requirement)
• Slew rate and gain bandwidth product
• Input bias current and input offset voltage
• Supply current per channel
• Output current capability per channel
• Supply voltage range (minimum 3V, maximum 16V)
• Operating temperature range

Mechanical Compatibility Criteria:

• Surface mount mounting type
• 8-SOIC package configuration
• Pin count and pinout compatibility

Substitute parts must maintain electrical performance within the specified operating envelope while meeting mechanical packaging requirements. Parts are grouped based on whether they provide direct functional equivalence or represent acceptable alternatives with modified electrical characteristics.

Engineering Selection Recommendations

TLC272BCDR (Primary Substitute)

The TLC272BCDR is the manufacturer-recommended substitute for the TLC272BCPS. Both devices share identical electrical specifications including CMOS amplifier type, 2.2 MHz gain bandwidth product, 5.3 V/µs slew rate, and 1.9 mA supply current per dual-channel configuration. The TLC272BCDR maintains the same 0°C to 70°C operating temperature range and 3V to 16V supply voltage span. The primary difference is packaging format: TLC272BCDR is supplied in Cut Tape and Digi-Reel format versus tube packaging for the TLC272BCPS. Both use 8-SOIC surface mount packages with identical pinout compatibility. The TLC272BCDR holds Active product status with 5200 units in stock, providing superior long-term availability compared to the Last Time Buy status of the TLC272BCPS. This part is suitable for direct replacement in new designs and production transitions.

LM432MA/NOPB (Alternative Substitute)

The LM432MA/NOPB is a General Purpose amplifier that provides functional substitution with modified electrical characteristics. This device maintains dual-channel configuration, 30 mA output current per channel, and 8-SOIC surface mount packaging. However, the LM432MA/NOPB exhibits reduced performance in several parameters: 1 MHz gain bandwidth product (versus 2.2 MHz), 3 nanoampere input bias current (versus 0.7 picoampere), 600 µV input offset voltage (versus 290 µV), and significantly reduced supply current of 0.15 mA per dual-channel configuration. The LM432MA/NOPB supports an extended operating temperature range of −40°C to 85°C and a lower minimum supply voltage of 2.5V. The device is designated Obsolete, limiting future availability. Selection of this part is appropriate only when reduced bandwidth and increased input offset voltage are acceptable for the application, and when extended temperature range operation is required.

Frequently Asked Questions (FAQ)

Q: Can TLC272BCDR be used as a direct replacement for TLC272BCPS?

A: Yes. The TLC272BCDR provides direct electrical and functional equivalence to the TLC272BCPS. Both devices are CMOS dual-channel amplifiers with identical electrical specifications including slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, and output current. The primary difference is packaging format (Cut Tape/Digi-Reel versus tube). Pinout and 8-SOIC package configuration are identical. The TLC272BCDR is the manufacturer-recommended substitute.

Q: What are the key differences between TLC272BCPS and LM432MA/NOPB?

A: The LM432MA/NOPB is a General Purpose amplifier with reduced electrical performance compared to the CMOS TLC272BCPS. The LM432MA/NOPB has a 1 MHz gain bandwidth product versus 2.2 MHz, higher input offset voltage of 600 µV versus 290 µV, and significantly lower supply current of 0.15 mA versus 1.9 mA per dual-channel configuration. The LM432MA/NOPB supports extended operating temperature range (−40°C to 85°C) and lower minimum supply voltage (2.5V). Both maintain 30 mA output current per channel and 8-SOIC surface mount packaging.

Q: Is the LM432MA/NOPB suitable for all applications using TLC272BCPS?

A: No. The LM432MA/NOPB is suitable only for applications where reduced bandwidth and higher input offset voltage are acceptable. The 1 MHz gain bandwidth product and 600 µV input offset voltage represent significant performance degradation compared to the TLC272BCPS specifications. Applications requiring the full 2.2 MHz bandwidth or precision offset voltage performance must use the TLC272BCDR or equivalent CMOS amplifier.

Q: What is the difference in package dimensions between TLC272BCPS and TLC272BCDR?

A: The TLC272BCPS uses an 8-SOIC package with 0.209" (5.30mm) width, while the TLC272BCDR uses an 8-SOIC package with 0.154" (3.90mm) width. Both are surface mount 8-SOIC configurations with identical pinout. The narrower package of the TLC272BCDR represents a more compact form factor. PCB layout modifications may be required if switching from TLC272BCPS to TLC272BCDR due to the different package width.

Q: Why is TLC272BCPS designated as Last Time Buy?

A: Last Time Buy status indicates that the TLC272BCPS has been discontinued by the manufacturer and existing inventory represents the final production lot. No future production is planned. The TLC272BCDR is the active replacement product and should be used for all new designs and production transitions to ensure long-term component availability.

Q: Are all three parts RoHS3 compliant?

A: Yes. The TLC272BCPS, TLC272BCDR, and LM432MA/NOPB are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). All three parts are suitable for applications requiring RoHS compliance.

Q: What is the supply voltage compatibility across these parts?

A: The TLC272BCPS and TLC272BCDR both operate across 3V to 16V supply voltage range. The LM432MA/NOPB operates across 2.5V to 16V, providing a lower minimum supply voltage. All three parts are compatible with standard 5V and 12V supply rails commonly used in industrial and consumer applications.
