Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLC271CDRG4 is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Amplifier Type: General Purpose
• Number of Circuits: 1
• Voltage Supply Range: 3V to 16V minimum and maximum
• Operating Temperature Range: 0°C to 70°C
• Current Output per Channel: 30 mA minimum

Mechanical Compatibility Requirements:

• Mounting Type: Surface Mount
• Package / Case: 8-SOIC (0.154", 3.90mm Width)

Compliance Requirements:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts must satisfy all electrical, mechanical, and compliance requirements. Performance parameters such as slew rate, gain bandwidth product, input bias current, and input offset voltage may vary within acceptable application tolerances but do not disqualify substitution when other critical parameters align.

Engineering Selection Recommendations

TLC271CDR (Texas Instruments)

The TLC271CDR is the manufacturer-recommended equivalent for the TLC271CDRG4. This part maintains identical electrical specifications including slew rate (5.3V/µs) and gain bandwidth product (2.2 MHz). Both devices are manufactured by Texas Instruments and belong to the LinCMOS™ series. The TLC271CDR is available in Cut Tape and Digi-Reel® packaging with significantly higher inventory (45,950 pcs). The product status is Last Time Buy, indicating controlled availability. This part is ROHS3 compliant with MSL 1 rating, matching the original specification. Selection of TLC271CDR is appropriate for direct replacement in existing designs without circuit modification.

TLC27L1CS-13 (Diodes Incorporated)

The TLC27L1CS-13 is a CMOS amplifier variant manufactured by Diodes Incorporated. This part satisfies all mechanical and compliance requirements: 8-SOIC package, surface mount configuration, ROHS3 compliance, and MSL 1 rating. The supply voltage range (3V to 16V) and output current capability (30 mA) are identical to the original part. The TLC27L1CS-13 is currently in active production status with 3,600 pcs in stock. However, this part exhibits significantly reduced performance specifications: slew rate of 0.04V/µs (versus 5.3V/µs) and gain bandwidth product of 110 kHz (versus 2.2 MHz). Additionally, input offset voltage is 10 mV compared to 1.1 mV, and supply current is 14 µA versus 950 µA. Selection of TLC27L1CS-13 is appropriate only for applications where reduced bandwidth and slew rate are acceptable, and where ultra-low power consumption is a design requirement.

Frequently Asked Questions (FAQ)

Q: Can TLC271CDR be used as a direct replacement for TLC271CDRG4?

A: Yes. The TLC271CDR is electrically and mechanically identical to the TLC271CDRG4. Both parts share the same slew rate (5.3V/µs), gain bandwidth product (2.2 MHz), input bias current (0.7 pA), input offset voltage (1.1 mV), supply current (950 µA), and output current capability (30 mA). Both operate across 3V to 16V supply range and 0°C to 70°C temperature range. Both are packaged in 8-SOIC and are ROHS3 compliant with MSL 1 rating. No circuit modification is required.

Q: What are the key differences between TLC271CDR and TLC27L1CS-13?

A: The primary differences are performance-based and power consumption-based. TLC271CDR maintains the original TLC271CDRG4 specifications with 5.3V/µs slew rate and 2.2 MHz bandwidth. TLC27L1CS-13 is a CMOS variant with significantly reduced slew rate (0.04V/µs) and bandwidth (110 kHz), but operates at ultra-low supply current (14 µA versus 950 µA). Both parts are mechanically compatible and ROHS3 compliant. Selection depends on application bandwidth requirements and power consumption constraints.

Q: Is the TLC27L1CS-13 suitable for high-speed applications?

A: No. The TLC27L1CS-13 has a gain bandwidth product of 110 kHz and slew rate of 0.04V/µs, making it unsuitable for applications requiring bandwidth above 110 kHz or fast signal transitions. The TLC271CDR is the appropriate choice for applications requiring the original 2.2 MHz bandwidth and 5.3V/µs slew rate specifications.

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

A: Yes. All three parts (TLC271CDRG4, TLC271CDR, and TLC27L1CS-13) are packaged in 8-SOIC (0.154", 3.90mm Width) surface mount configuration. PCB layout and footprint compatibility are maintained across all three parts.

Q: What is the product status of each part?

A: TLC271CDRG4 is discontinued at DiGi Electronics. TLC271CDR is Last Time Buy status, indicating limited future availability. TLC27L1CS-13 is in active production status with ongoing availability. For long-term supply assurance, TLC27L1CS-13 is the recommended choice if application specifications permit its reduced performance parameters.

Q: Do all substitute parts meet RoHS and REACH compliance?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected. All parts have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.
