TLC271ACD Equivalent & Substitute Parts

Part Overview

The TLC271ACD is a general-purpose operational amplifier manufactured by Texas Instruments, housed in an 8-SOIC surface mount package. This device is classified as a Last Time Buy product, indicating limited future availability. The TLC271ACD operates across a 3V to 16V supply range and is suitable for low-power analog signal processing applications requiring moderate bandwidth performance.

Due to Last Time Buy status, identifying functionally equivalent substitute components is essential for design continuity and long-term supply chain planning. Substitute parts must maintain compatibility across electrical performance parameters, package dimensions, and operating conditions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLC271ACD is determined by strict alignment of the following critical parameters:

Mandatory Compatibility Criteria:

• Package / Case: 8-SOIC (0.154", 3.90mm Width) surface mount configuration
• Voltage - Supply Span: 3V minimum to 16V maximum
• Number of Circuits: Single circuit (1)
• Current - Output / Channel: 30 mA minimum
• Operating Temperature Range: 0°C to 70°C
• RoHS3 Compliance and MSL Level 1 rating

Performance Parameters Defining Substitution Class:

• Slew Rate: 5.3 V/µs (primary performance metric)
• Gain Bandwidth Product: 2.2 MHz (bandwidth specification)
• Current - Input Bias: 0.7 pA (input characteristics)
• Voltage - Input Offset: 900 µV (DC accuracy)
• Current - Supply: 950 µA (power consumption)

Identified substitute parts maintain identical package geometry and electrical interface specifications. Variations in secondary performance parameters (slew rate, gain bandwidth product, supply current) indicate different amplifier architectures or design generations but remain functionally compatible within the specified operating envelope.

Parameter Comparison

Engineering Selection Recommendations

TLC271ACDR (Texas Instruments)

The TLC271ACDR is the direct manufacturer-recommended substitute for TLC271ACD. Both devices share identical electrical specifications, including slew rate (5.3 V/µs), gain bandwidth product (2.2 MHz), and supply current (950 µA). The primary distinction is packaging format: TLC271ACDR is supplied in Cut Tape and Digi-Reel format, whereas TLC271ACD is supplied in Tube packaging. Both maintain Last Time Buy status, indicating coordinated end-of-life management by Texas Instruments. Pin-for-pin compatibility and identical performance characteristics enable direct substitution without circuit redesign. Current inventory availability is 1784 units.

TLC27L1CS-13 (Diodes Incorporated)

The TLC27L1CS-13 represents an alternative substitute with different performance characteristics. This device is classified as Active product status, providing extended availability compared to Last Time Buy alternatives. The TLC27L1CS-13 exhibits significantly lower slew rate (0.04 V/µs versus 5.3 V/µs) and reduced gain bandwidth product (110 kHz versus 2.2 MHz), indicating a lower-speed CMOS architecture. Supply current is substantially reduced (14 µA versus 950 µA), and input offset voltage is improved (10 µV versus 900 µV). Package, mounting type, supply voltage range, and output current specifications remain identical. Selection of TLC27L1CS-13 is appropriate for applications where bandwidth and slew rate requirements are less stringent and power consumption minimization is prioritized. Current inventory availability is 3600 units.

Compliance and Regulatory Status

All identified substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and identical ECCN (EAR99) and HTSUS (8542.33.0001) classifications. No regulatory or compliance barriers exist for substitution within the specified alternatives.

Frequently Asked Questions (FAQ)

Q: Can TLC271ACDR be used as a direct replacement for TLC271ACD?

A: Yes. TLC271ACDR is the manufacturer-recommended substitute with identical electrical specifications and pin configuration. The only difference is packaging format (Cut Tape/Digi-Reel versus Tube). No circuit modifications are required.

Q: What is the primary difference between TLC271ACDR and TLC27L1CS-13?

A: TLC271ACDR maintains the original performance specifications (5.3 V/µs slew rate, 2.2 MHz bandwidth, 950 µA supply current). TLC27L1CS-13 is a lower-performance CMOS variant with reduced slew rate (0.04 V/µs), lower bandwidth (110 kHz), and significantly lower supply current (14 µA). Selection depends on application bandwidth requirements and power consumption constraints.

Q: Is the 8-SOIC package identical across all three parts?

A: Yes. All three parts use the 8-SOIC package with 0.154" (3.90mm) width. Pin assignments and PCB footprints are identical, enabling direct board-level substitution.

Q: Why is TLC271ACD marked as Last Time Buy?

A: Last Time Buy status indicates the manufacturer has discontinued or will discontinue production. This designation requires customers to secure final inventory quantities before availability ends. Identifying active substitute parts (such as TLC27L1CS-13) ensures long-term design continuity.

Q: Can TLC27L1CS-13 be used in high-speed signal processing applications?

A: No. The TLC27L1CS-13 slew rate of 0.04 V/µs and gain bandwidth product of 110 kHz are unsuitable for applications requiring fast transient response or high-frequency signal processing. Applications requiring the original 5.3 V/µs slew rate and 2.2 MHz bandwidth must use TLC271ACDR or equivalent high-speed variants.

Q: Are there any supply voltage or temperature range differences?

A: No. All three parts operate across identical supply voltage ranges (3V to 16V) and temperature ranges (0°C to 70°C). Supply voltage and temperature compatibility is universal across all substitutes.

Q: What is the current inventory status for each part?

A: TLC271ACD: 2100 units (Tube packaging). TLC271ACDR: 1784 units (Cut Tape/Digi-Reel). TLC27L1CS-13: 3600 units (Tape & Reel). Inventory levels should be verified with the supplier for current availability.

Q: Do all parts meet RoHS3 compliance requirements?

A: Yes. TLC271ACD, TLC271ACDR, and TLC27L1CS-13 are all ROHS3 compliant with MSL Level 1 rating. No environmental or regulatory restrictions apply to substitution.
