TLC27L9CDR Equivalent & Substitute Parts

Part Overview

The TLC27L9CDR is a general-purpose operational amplifier manufactured by Texas Instruments, featuring four independent circuits in a 14-SOIC surface-mount package. This LinCMOS™ series device operates across a 3V to 16V supply range and is designed for low-power applications requiring moderate bandwidth performance. The device maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are necessary when the TLC27L9CDR becomes unavailable, when alternative packaging formats are required, or when application requirements demand enhanced performance characteristics such as extended temperature ranges or increased slew rate capabilities.

All substitute parts listed maintain identical package dimensions (14-SOIC, 0.154" width, 3.90mm), identical supply voltage ranges (3V to 16V), and surface-mount configuration. Substitutes are grouped by performance tier: standard performance (TS27L4 series) and enhanced performance (TS27M4 series).

Parameter Comparison

Engineering Selection Recommendations

TS27L4AIDT (STMicroelectronics)

This substitute provides equivalent functionality with extended operating temperature range (-40°C to 125°C) compared to the TLC27L9CDR (0°C to 70°C). The TS27L4AIDT maintains identical supply voltage specifications, package configuration, and circuit count. Supply current is reduced to 10µA per channel versus 57µA, resulting in lower power consumption. Output current capability increases to 45mA per channel. This device is suitable for applications requiring wider temperature operation and reduced quiescent current. Packaging format is Tape & Reel (TR). All compliance certifications (RoHS3, REACH Unaffected, EAR99) are maintained.

TS27L4CDT (STMicroelectronics)

This substitute maintains identical operating temperature range (0°C to 70°C) as the TLC27L9CDR, ensuring direct thermal compatibility. Package configuration, circuit count, and supply voltage range are identical. Supply current is reduced to 10µA per channel. Output current capability increases to 45mA per channel. Packaging format is Cut Tape (CT). This device is recommended for direct replacement in applications where temperature range matching is required and packaging format flexibility is acceptable. RoHS3 compliance and all regulatory certifications are maintained. Inventory availability is significantly higher (30,200 units).

TS27L4IDT (STMicroelectronics)

This substitute provides extended operating temperature range (-40°C to 125°C) with identical electrical specifications to TS27L4CDT. Package configuration, circuit count, and supply voltage range match the TLC27L9CDR. Supply current is reduced to 10µA per channel. Output current capability increases to 45mA per channel. Packaging format is Cut Tape (CT) & Digi-Reel®. This device is suitable for applications requiring wider temperature operation with flexible packaging options. All compliance certifications are maintained.

TS27M4IDT (STMicroelectronics)

This substitute provides enhanced performance characteristics with 20-fold increase in gain bandwidth product (1MHz versus 110kHz) and 20-fold increase in slew rate (0.6V/µs versus 0.03V/µs). Extended operating temperature range (-40°C to 125°C) is provided. Package configuration, circuit count, and supply voltage range remain identical to the TLC27L9CDR. Supply current increases to 150µA per channel due to enhanced performance. Output current capability is 45mA per channel. This device is recommended for applications requiring higher bandwidth and faster transient response. All compliance certifications are maintained.

Frequently Asked Questions (FAQ)

Q: Can TS27L4AIDT, TS27L4CDT, and TS27L4IDT be used interchangeably with TLC27L9CDR?

A: Yes, within the constraints of operating temperature requirements. TS27L4CDT matches the 0°C to 70°C temperature range of the TLC27L9CDR. TS27L4AIDT and TS27L4IDT extend the temperature range to -40°C to 125°C, which is compatible with but exceeds the TLC27L9CDR specification. All three maintain identical package configuration (14-SOIC), circuit count (4), and supply voltage range (3V to 16V).

Q: What is the primary difference between TS27L4 and TS27M4 series substitutes?

A: The TS27M4IDT provides significantly enhanced performance with 1MHz gain bandwidth product and 0.6V/µs slew rate, compared to 100kHz and 0.04V/µs for the TS27L4 series. The TS27M4IDT is suitable for applications requiring higher-speed operation. Supply current consumption increases to 150µA per channel for the TS27M4IDT versus 10µA for TS27L4 devices.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (TS27L4AIDT, TS27L4CDT, TS27L4IDT, and TS27M4IDT) maintain ROHS3 compliance status identical to the TLC27L9CDR. All devices are REACH Unaffected and classified as EAR99 for export control purposes.

Q: What packaging format differences exist among the substitutes?

A: TS27L4AIDT is supplied in Tape & Reel (TR) format. TS27L4CDT is supplied in Cut Tape (CT) format. TS27L4IDT is supplied in Cut Tape (CT) & Digi-Reel® format. TS27M4IDT is supplied in Cut Tape (CT) format. All devices use identical 14-SOIC package configuration (0.154" width, 3.90mm) suitable for surface-mount assembly.

Q: Does the TLC27L9CDR require substitution based on performance limitations?

A: The TLC27L9CDR remains an Active product with 1,228 units in stock. Substitution is necessary only when the device becomes unavailable, when alternative packaging formats are required, or when application requirements demand enhanced performance characteristics such as extended temperature operation or increased bandwidth.

Q: Can TS27M4IDT be used in applications designed for TLC27L9CDR?

A: Yes. The TS27M4IDT maintains identical package configuration, circuit count, and supply voltage range. However, the increased supply current (150µA versus 57µA per channel) and enhanced performance characteristics (1MHz bandwidth, 0.6V/µs slew rate) must be evaluated for power budget and circuit stability implications in the target application.

Q: What is the moisture sensitivity rating for all substitute parts?

A: All substitute parts maintain Moisture Sensitivity Level (MSL) 1 (Unlimited), identical to the TLC27L9CDR. This indicates no moisture sensitivity restrictions for storage, handling, or assembly processes.
