TLV27L1CD Equivalent & Substitute Parts

Part Overview

The TLV27L1CD is a general-purpose operational amplifier manufactured by Texas Instruments, housed in an 8-SOIC surface-mount package. This device features rail-to-rail output capability and operates across a 2.7 V to 16 V supply range. The TLV27L1CD is classified as obsolete, necessitating identification of active equivalent and substitute components for new designs and ongoing production requirements. Substitute parts must maintain functional compatibility while meeting current availability and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV27L1CD is determined by the following critical parameters: package type (8-SOIC surface mount), output configuration (rail-to-rail), single-circuit topology, and supply voltage range compatibility (minimum 2.7 V, maximum 16 V). All substitute parts must maintain these core electrical and mechanical specifications to ensure direct functional replacement without circuit redesign.

Substitute parts are grouped into two categories:

Category 1: Direct Electrical Equivalents (Texas Instruments TLV27L1 Series) These parts maintain identical electrical characteristics to the TLV27L1CD, including slew rate (0.06 V/µs), gain bandwidth product (160 kHz), input bias current (1 pA), and input offset voltage (500 µV). The TLV27L1IDR differs only in packaging format (Tape & Reel versus Tube) and operating temperature range, with active product status and expanded temperature capability.

Category 2: Functional Equivalents with Enhanced Performance (Microchip MCP6H01 Series and Diodes TLV271 Series) These parts provide rail-to-rail output in 8-SOIC packages with compatible supply voltage ranges. The MCP6H01-E/SN and MCP6H01T-E/SN offer higher slew rate (0.8 V/µs) and gain bandwidth product (1.2 MHz) compared to the TLV27L1CD. The TLV271CS-13 and TLV271IS-13 (Diodes Incorporated) provide CMOS amplifier topology with slew rate of 2 V/µs and gain bandwidth product of 1.9–2 MHz. All substitute parts are active products with ROHS3 compliance and MSL 1 rating.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance)

The TLV27L1IDR is the primary substitute for the obsolete TLV27L1CD. Both parts maintain identical electrical specifications: 0.06 V/µs slew rate, 160 kHz gain bandwidth product, 1 pA input bias current, and 500 µV input offset voltage. The TLV27L1IDR is available in active product status with Tape & Reel packaging and extended operating temperature range (-40°C to 125°C). This part is suitable for applications requiring exact electrical equivalence with no circuit modifications.

For Enhanced Performance Applications

The MCP6H01-E/SN and MCP6H01T-E/SN (Microchip Technology) provide higher performance characteristics within the same 8-SOIC package. These parts offer 0.8 V/µs slew rate and 1.2 MHz gain bandwidth product, representing 13× and 7.5× improvements respectively over the TLV27L1CD. Supply voltage minimum is 3.5 V (versus 2.7 V for TLV27L1CD), which must be verified for compatibility with existing power supply designs. Both MCP6H01 variants are active products with ROHS3 compliance and MSL 1 rating.

For Low-Power and High-Speed Applications

The TLV271CS-13 and TLV271IS-13 (Diodes Incorporated) employ CMOS amplifier topology with 2 V/µs slew rate and 1.9–2 MHz gain bandwidth product. These parts maintain 2.7 V minimum supply voltage compatibility with the TLV27L1CD. The TLV271IS-13 offers extended operating temperature range (-40°C to 125°C) compared to TLV271CS-13 (0°C to 70°C). Supply current is higher (550 µA versus 7 µA for TLV27L1CD), which must be evaluated for power budget constraints.

All substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage processes.

Frequently Asked Questions (FAQ)

Q: Can the TLV27L1IDR be used as a direct replacement for the TLV27L1CD without circuit modifications?

A: Yes. The TLV27L1IDR maintains identical electrical specifications including slew rate (0.06 V/µs), gain bandwidth product (160 kHz), input bias current (1 pA), input offset voltage (500 µV), and supply voltage range (2.7 V to 16 V). The only differences are packaging format (Tape & Reel versus Tube) and operating temperature range (-40°C to 125°C versus 0°C to 70°C). No circuit redesign is required.

Q: What is the primary difference between the TLV27L1CD and the MCP6H01 series?

A: The MCP6H01-E/SN and MCP6H01T-E/SN provide significantly higher performance: slew rate of 0.8 V/µs (13× faster) and gain bandwidth product of 1.2 MHz (7.5× higher). However, the minimum supply voltage is 3.5 V instead of 2.7 V, and supply current is 135 µA versus 7 µA. These parts are suitable for applications requiring higher bandwidth and faster transient response, provided the 3.5 V minimum supply voltage is compatible with the design.

Q: Are all substitute parts available in the same 8-SOIC package?

A: Yes. All substitute parts are housed in 8-SOIC (0.154", 3.90mm Width) surface-mount packages, ensuring mechanical compatibility with existing PCB layouts and assembly processes. Packaging format differs (Tube versus Tape & Reel), but the physical package dimensions are identical.

Q: What is the difference between TLV271CS-13 and TLV271IS-13?

A: Both parts are CMOS amplifiers from Diodes Incorporated with identical electrical specifications: 2 V/µs slew rate, 1.9–2 MHz gain bandwidth product, and 2.7 V to 16 V supply range. The primary difference is operating temperature range: TLV271CS-13 operates 0°C to 70°C, while TLV271IS-13 operates -40°C to 125°C. Select TLV271IS-13 for applications requiring extended temperature capability.

Q: Which substitute part has the lowest supply current consumption?

A: The TLV27L1IDR maintains the lowest supply current at 7 µA, identical to the TLV27L1CD. The MCP6H01 series draws 135 µA, and the TLV271 series draws 550 µA. For battery-powered or ultra-low-power applications, the TLV27L1IDR is the appropriate choice.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (TLV27L1IDR, MCP6H01-E/SN, MCP6H01T-E/SN, TLV271CS-13, and TLV271IS-13) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. These parts meet current environmental and regulatory requirements for electronic component manufacturing and assembly.

Q: Can the MCP6H01 series be used in applications designed for the TLV27L1CD?

A: The MCP6H01 series can be used if the application can tolerate higher supply current (135 µA versus 7 µA) and requires minimum supply voltage of 3.5 V or higher. The enhanced performance characteristics (0.8 V/µs slew rate and 1.2 MHz bandwidth) are beneficial for higher-frequency applications. Verify that the 3.5 V minimum supply voltage is compatible with the existing power supply design before substitution.

Q: What is the inventory status of each substitute part?

A: TLV27L1IDR has 3,298 pieces in stock. MCP6H01-E/SN has 3,000,100 pieces in stock. MCP6H01T-E/SN has 16,385 pieces in stock. TLV271CS-13 has 4,400 pieces in stock. TLV271IS-13 has 2,060 pieces in stock. All substitute parts are active products with confirmed availability.
