Substitute Part Grouping Explanation

Substitution of the TLC25L2CPWRG4 is determined by the following critical parameters:

Package Compatibility: All substitute parts must use the 8-TSSOP surface mount package with identical physical dimensions (0.173", 4.40mm Width).

Circuit Configuration: All substitutes must contain 2 amplifier circuits in CMOS technology.

Supply Voltage Range: The TLC25L2CPWRG4 operates from 1.4 V to 16 V. Substitute parts must support this range or a compatible subset that includes the maximum 16 V specification.

Temperature Rating: The original part operates from 0°C to 70°C. Substitutes with extended temperature ranges (-40°C to 125°C) are functionally compatible for this application.

Electrical Characteristics: Input offset voltage (1.1 mV), input bias current (0.7 pA to 1 pA range), and output type are critical matching parameters.

Compliance: All substitute parts must maintain ROHS3 compliance and REACH unaffected status.

The following STMicroelectronics parts meet these substitution criteria: TS272CPT, TS272IPT, TS27L2CPT, TS27L2IPT, and TS27M2CPT.

Engineering Selection Recommendations

Primary Substitutes (Direct Replacement):

TS27L2CPT and TS27L2IPT are the closest functional equivalents to the TLC25L2CPWRG4. Both parts maintain the same gain bandwidth product (100 kHz) and slew rate (0.04 V/µs) as the original device, with identical input offset voltage specifications. TS27L2CPT operates within the original temperature range (0°C to 70°C), while TS27L2IPT extends the operating temperature to -40°C to 125°C. Both are active products with full ROHS3 compliance.

Secondary Substitutes (Performance Enhancement):

TS272CPT and TS272IPT offer significantly improved performance characteristics with a gain bandwidth product of 3.5 MHz and slew rate of 5.5 V/µs, compared to the original 110 kHz and 2.9 V/µs. These parts are suitable for applications requiring higher bandwidth performance. TS272CPT maintains the 0°C to 70°C temperature range, while TS272IPT provides extended temperature operation (-40°C to 125°C).

Alternative Substitute (Moderate Performance):

TS27M2CPT provides intermediate performance with a gain bandwidth product of 1 MHz and slew rate of 0.6 V/µs. This part operates within the original temperature range (0°C to 70°C) and is suitable for applications requiring moderate bandwidth enhancement.

Supply Voltage Consideration:

All substitute parts specify a minimum supply voltage of 3 V, compared to the original part's 1.4 V minimum. Applications requiring operation below 3 V are not compatible with these substitutes.

Compliance and Availability:

All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility. All substitute parts are currently active products with established supply chains.

Frequently Asked Questions (FAQ)

Q: Can TS272CPT directly replace TLC25L2CPWRG4 in all applications?

A: TS272CPT is physically and electrically compatible in terms of package, pin configuration, and supply voltage range. However, the significantly higher gain bandwidth product (3.5 MHz vs. 110 kHz) and slew rate (5.5 V/µs vs. 2.9 V/µs) may affect circuit behavior in applications with specific frequency response requirements. Circuit validation is necessary for applications sensitive to these performance differences.

Q: What is the minimum supply voltage difference between the original part and substitutes?

A: The TLC25L2CPWRG4 operates from 1.4 V minimum, while all STMicroelectronics substitutes operate from 3 V minimum. Applications requiring operation below 3 V cannot use these substitute parts.

Q: Are TS27L2CPT and TS27L2IPT functionally identical?

A: TS27L2CPT and TS27L2IPT are functionally identical in electrical performance and package configuration. The primary difference is the operating temperature range: TS27L2CPT operates from 0°C to 70°C, while TS27L2IPT operates from -40°C to 125°C. Selection depends on the application's temperature requirements.

Q: What is the significance of the "I" designation in part numbers TS272IPT and TS27L2IPT?

A: The "I" designation indicates an extended industrial temperature range (-40°C to 125°C) compared to the "C" designation (0°C to 70°C). Both variants are otherwise electrically identical.

Q: Are all substitute parts available in the same packaging options?

A: TS272CPT, TS27L2CPT, and TS27M2CPT are available in Cut Tape (CT) and Digi-Reel® packaging. TS272IPT and TS27L2IPT are available in Tape & Reel (TR) packaging. Packaging selection depends on procurement and assembly requirements.

Q: Do all substitute parts maintain the same input offset voltage as the original?

A: Yes, all substitute parts specify an input offset voltage of 1.1 mV, identical to the TLC25L2CPWRG4.

Q: Which substitute part has the lowest power consumption?

A: TS27L2CPT and TS27L2IPT have the lowest supply current at 10 µA per channel (x2 channels), compared to the original part's 29 µA (x2 channels). TS272CPT and TS272IPT consume 1 mA per channel, while TS27M2CPT consumes 150 µA per channel.
