TLC271ID Equivalent & Substitute Parts

Part Overview

The TLC271ID is a general-purpose operational amplifier manufactured by Texas Instruments in the LinCMOS™ series. It is a single-circuit, 8-SOIC surface-mount device designed for low-power analog signal processing applications. The device operates across a wide supply voltage range of 4V to 16V and maintains performance across the industrial temperature range of -40°C to 85°C.

The TLC271ID is designated as Last Time Buy status, indicating that Texas Instruments has discontinued or will discontinue production. This status necessitates identification of equivalent and substitute parts to ensure design continuity and procurement availability for ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLC271ID is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Package / Case: 8-SOIC form factor with 0.154" (3.90mm) width
• Mounting Type: Surface Mount
• Number of Circuits: Single circuit configuration
• Current - Output / Channel: 30 mA minimum
• Voltage - Supply Span: Minimum 4V to maximum 16V overlap
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: MSL 1

Performance Parameters (Allowable Variation):

• Slew Rate: Minimum 0.04 V/µs
• Gain Bandwidth Product: Minimum 110 kHz
• Current - Input Bias: Maximum 0.7 pA
• Voltage - Input Offset: Maximum 10 mV
• Current - Supply: Maximum 950 µA
• Operating Temperature Range: Must encompass or match -40°C to 85°C

The TLC271IDR (Texas Instruments, Cut Tape packaging) and TLC27L1CS-13 (Diodes Incorporated, Tape & Reel packaging) meet these substitution criteria with identical or superior electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

TLC271IDR (Texas Instruments): The TLC271IDR is the direct equivalent of the TLC271ID, differing only in packaging format (Cut Tape & Digi-Reel® versus Tube). Electrical specifications, performance characteristics, and compliance certifications are identical. Both devices share Last Time Buy status. The TLC271IDR is suitable for applications requiring the same performance envelope as the original TLC271ID. Inventory availability is significantly higher (16,300 pcs versus 2,490 pcs), making this the preferred primary substitute.

TLC27L1CS-13 (Diodes Incorporated): The TLC27L1CS-13 is a CMOS-based alternative manufactured by Diodes Incorporated with Active product status. This device exhibits substantially lower power consumption (14 µA versus 950 µA supply current) and lower input offset voltage specification (10 mV versus 1.1 mV). However, it demonstrates reduced dynamic performance with slew rate of 0.04 V/µs and gain bandwidth product of 110 kHz compared to the TLC271ID specifications of 5.3 V/µs and 2.2 MHz respectively. The operating temperature range is narrower (0°C to 70°C versus -40°C to 85°C). The TLC27L1CS-13 is suitable only for applications where reduced bandwidth and lower operating temperature limits are acceptable, and where power consumption reduction is a design priority. This device is not recommended for high-speed signal processing or extended temperature range applications.

Frequently Asked Questions (FAQ)

Q: Can the TLC271IDR be used as a direct replacement for the TLC271ID?

A: Yes. The TLC271IDR is electrically and functionally identical to the TLC271ID. The only difference is the packaging format: TLC271IDR is supplied in Cut Tape & Digi-Reel® format, while TLC271ID is supplied in Tube format. Both devices are pin-compatible, have identical electrical specifications, and are suitable for direct substitution in PCB designs.

Q: What are the key differences between TLC271IDR and TLC27L1CS-13?

A: The TLC271IDR and TLC27L1CS-13 differ significantly in dynamic performance and power consumption. The TLC271IDR maintains the original TLC271ID specifications with 5.3 V/µs slew rate and 2.2 MHz bandwidth. The TLC27L1CS-13 has substantially lower slew rate (0.04 V/µs) and bandwidth (110 kHz), but consumes significantly less power (14 µA versus 950 µA). Additionally, TLC27L1CS-13 has a narrower operating temperature range (0°C to 70°C) and higher input offset voltage (10 mV). These differences make TLC27L1CS-13 unsuitable for high-speed applications.

Q: Is the TLC27L1CS-13 suitable for industrial temperature range applications?

A: No. The TLC27L1CS-13 operates only from 0°C to 70°C, which does not meet the industrial temperature range of -40°C to 85°C specified for the TLC271ID. Applications requiring extended temperature operation must use TLC271IDR or equivalent devices with matching temperature specifications.

Q: Why is the TLC271ID designated as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has ceased or will cease production of this device. Customers requiring this part must transition to alternative solutions. The TLC271IDR provides an immediate equivalent, while TLC27L1CS-13 offers an alternative for applications where reduced bandwidth and lower power consumption are acceptable trade-offs.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. Both TLC271IDR and TLC27L1CS-13 are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited), matching the compliance profile of the original TLC271ID.

Q: What packaging formats are available for these devices?

A: TLC271ID is supplied in Tube format. TLC271IDR is supplied in Cut Tape & Digi-Reel® format. TLC27L1CS-13 is supplied in Tape & Reel format. Selection depends on production volume requirements and assembly equipment compatibility.
