Engineering Selection Recommendations

For Direct Replacement (Obsolete to Active Transition):

The TLC27M2IPWR is the primary recommended substitute for the obsolete TLC27M2IPWRG4. This part maintains identical electrical specifications and operating parameters while offering active product status from Texas Instruments. Both components are ROHS3 compliant with MSL Level 1 rating. The only functional difference is packaging format (Tape & Reel vs. Tube). This substitute is suitable for applications requiring no design modification.

For Enhanced Performance Applications:

The TS272IPT (STMicroelectronics) is recommended when extended operating temperature range (-40°C to 125°C) and improved dynamic performance are required. This part provides 5.5 V/µs slew rate and 3.5 MHz gain bandwidth product compared to the original 0.62 V/µs and 635 kHz. Output current capability increases to 45 mA per channel. Supply voltage minimum reduces to 3V, expanding operational flexibility. ROHS3 compliance and MSL Level 1 certification are maintained.

For Low-Power Applications:

The TS27L2IPT (STMicroelectronics) is recommended for battery-powered or energy-constrained applications. This part reduces supply current to 10µA per channel pair (versus 285µA in the original). Extended operating temperature range (-40°C to 125°C) is provided. Trade-offs include reduced slew rate (0.04 V/µs) and gain bandwidth product (100 kHz). ROHS3 compliance and MSL Level 1 certification are maintained.

Both components feature identical slew rate (0.62 V/µs), gain bandwidth product (635 kHz), supply current (285µA per channel pair), and operating temperature range (-40°C to 85°C). The only difference is packaging format. No circuit redesign is required.

Q: What are the key differences between the TS272IPT and the original TLC27M2IPWRG4?

A: The TS272IPT provides enhanced performance with 5.5 V/µs slew rate (versus 0.62 V/µs), 3.5 MHz gain bandwidth product (versus 635 kHz), and extended operating temperature range (-40°C to 125°C versus -40°C to 85°C). Supply current increases to 1mA per channel pair. Output current capability increases to 45 mA per channel. Supply voltage minimum reduces to 3V. These differences make the TS272IPT suitable for higher-speed applications.

Q: Is the TS27L2IPT suitable for all applications using the TLC27M2IPWRG4?

A: No. The TS27L2IPT is optimized for low-power operation with only 10µA supply current per channel pair. However, it provides significantly reduced slew rate (0.04 V/µs) and gain bandwidth product (100 kHz). This part is suitable only for applications where low power consumption is prioritized over dynamic performance. Circuit performance must be evaluated for compatibility.

Q: Are all substitute parts available in the same 8-TSSOP package?

A: Yes. All substitute parts listed are packaged in 8-TSSOP surface mount configuration with identical mechanical dimensions (0.173" width, 4.40mm width). PCB footprints are compatible across all parts.

Q: What is the difference between TS272CPT and TS272IPT?

A: Both parts are electrically identical with 5.5 V/µs slew rate and 3.5 MHz gain bandwidth product. The primary difference is operating temperature range: TS272CPT operates 0°C to 70°C, while TS272IPT operates -40°C to 125°C. Select TS272IPT for extended temperature applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating. REACH Unaffected status is maintained across all parts.

Q: Can I use TS27M2CPT as a direct replacement?

A: The TS27M2CPT is functionally compatible but not a direct replacement. It provides improved slew rate (0.6 V/µs versus 0.62 V/µs) and gain bandwidth product (1 MHz versus 635 kHz). Supply current is reduced to 150µA per channel pair. Operating temperature range is limited to 0°C to 70°C. Circuit performance should be evaluated for compatibility with these parameter changes.

Q: What supply voltage range is supported by all substitute parts?

A: All substitute parts support 3V to 16V supply voltage range. The original TLC27M2IPWRG4 requires minimum 4V. Substitute parts with 3V minimum rating provide expanded operational flexibility in low-voltage applications.

Q: Which substitute part provides the lowest power consumption?

A: The TS27L2IPT and TS27L2CPT provide the lowest supply current at 10µA per channel pair. These parts are optimized for battery-powered and energy-constrained applications. Trade-offs include reduced slew rate (0.04 V/µs) and gain bandwidth product (100 kHz).
