TLC25L2CPWR Equivalent & Substitute Parts

Part Overview

The TLC25L2CPWR is a CMOS amplifier integrated circuit manufactured by Texas Instruments, containing 2 circuits in a single-ended configuration. The device is packaged in an 8-TSSOP surface mount package and operates across a supply voltage range of 1.4 V to 16 V with an operating temperature range of 0°C to 70°C. The TLC25L2CPWR is classified as an obsolete product. Due to its obsolete status and limited availability, equivalent substitute parts from active product lines are necessary for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC25L2CPWR 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) to ensure direct PCB compatibility without layout modifications.

Circuit Configuration: All substitutes maintain 2 CMOS amplifier circuits per device, preserving the functional density of the original design.

Supply Voltage Range: The original part operates from 1.4 V to 16 V. Substitute parts must support the maximum supply voltage of 16 V. Minimum supply voltage requirements vary by substitute part and must be evaluated against specific application requirements.

Operating Temperature Range: The original part operates from 0°C to 70°C. Substitute parts are available in both the same temperature range (0°C to 70°C) and extended range (-40°C to 125°C).

Electrical Characteristics: Input offset voltage (1.1 mV) and input bias current (1 pA) are consistent across all substitute parts. Slew rate, gain bandwidth product, and supply current vary by substitute part model and determine performance suitability for specific applications.

Compliance & Certifications: All substitute parts maintain ROHS3 compliance, MSL Level 1 (Unlimited), REACH Unaffected status, and identical ECCN and HTSUS classifications.

Parameter Comparison

Engineering Selection Recommendations

TS27L2CPT and TS27L2IPT are the closest functional equivalents to the TLC25L2CPWR. These parts maintain the lowest supply current (10 µA per channel) and gain bandwidth product (100 kHz) specifications, closely matching the original device's low-power characteristics. TS27L2CPT operates within the standard temperature range (0°C to 70°C), while TS27L2IPT extends to -40°C to 125°C for applications requiring wider temperature performance. Both are active products with full availability.

TS27M2CPT provides a mid-range alternative with 150 µA supply current and 1 MHz gain bandwidth product, suitable for applications requiring moderate performance enhancement over the original part while maintaining reasonable power consumption.

TS272CPT and TS272IPT offer the highest performance specifications with 5.5 V/µs slew rate and 3.5 MHz gain bandwidth product. These parts consume 1 mA per channel and are appropriate for applications requiring significantly improved frequency response. TS272CPT operates at standard temperature range, while TS272IPT supports extended temperature operation.

All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and identical regulatory classifications (REACH Unaffected, ECCN EAR99, HTSUS 8542.33.0001) as the original device. Selection should be based on specific application requirements for slew rate, bandwidth, power consumption, and operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can TS272CPT directly replace TLC25L2CPWR in existing designs?

A: TS272CPT is pin-compatible and uses the identical 8-TSSOP package. However, the minimum supply voltage requirement is 3 V compared to 1.4 V for the original part. If your application operates below 3 V, this substitute is not suitable. Additionally, TS272CPT has higher supply current (1 mA vs. 29 µA) and significantly higher gain bandwidth product (3.5 MHz vs. 110 kHz), which may affect circuit behavior in low-frequency or power-sensitive applications.

Q: What is the difference between TS27L2CPT and TS27L2IPT?

A: Both parts are functionally identical with the same electrical specifications. The primary difference is operating temperature range: TS27L2CPT operates from 0°C to 70°C, while TS27L2IPT operates from -40°C to 125°C. TS27L2IPT is suitable for industrial and automotive applications requiring extended temperature performance. Packaging differs as well: TS27L2CPT is supplied in Cut Tape format, while TS27L2IPT is supplied in Tape & Reel format.

Q: Why do substitute parts have a minimum supply voltage of 3 V instead of 1.4 V?

A: The STMicroelectronics TS27 series amplifiers are designed with different internal architecture than the original TLC25L2CPWR, resulting in a higher minimum operating voltage specification. Applications requiring operation below 3 V cannot use these substitutes and require alternative solutions.

Q: Which substitute part should I select for low-power applications?

A: TS27L2CPT and TS27L2IPT consume only 10 µA per channel, making them the lowest-power options among the available substitutes. These parts are appropriate for battery-powered or energy-constrained applications. If extended temperature operation is required, select TS27L2IPT; otherwise, TS27L2CPT is suitable for standard temperature ranges.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed (TS272CPT, TS272IPT, TS27L2CPT, TS27L2IPT, TS27M2CPT) are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating. All maintain REACH Unaffected status and identical regulatory classifications as the original TLC25L2CPWR.

Q: What is the impact of different slew rates on circuit performance?

A: Slew rate determines how quickly the amplifier output can change voltage. The original TLC25L2CPWR has a slew rate of 2.9 V/µs. TS27L2CPT and TS27L2IPT have significantly lower slew rates (0.04 V/µs), suitable for low-frequency signal processing. TS27M2CPT (0.6 V/µs) and TS272 variants (5.5 V/µs) provide intermediate and high-speed options respectively. Selection depends on the maximum frequency content of signals in your application.

Q: Can I use TS272IPT in place of TS272CPT?

A: Yes, TS272IPT is functionally equivalent to TS272CPT with identical electrical specifications. The difference is operating temperature range: TS272IPT supports -40°C to 125°C versus 0°C to 70°C for TS272CPT. TS272IPT is suitable for all applications where TS272CPT is used, with the added benefit of extended temperature operation. Packaging format differs (Tape & Reel vs. Cut Tape).
