Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLV2371IDRG4 is determined by strict alignment across the following critical parameters:

Package Compatibility: All substitute parts must use the 8-SOIC surface-mount package with 0.154" (3.90mm) width to ensure PCB footprint compatibility without layout modifications.

Electrical Specifications: Substitute parts must maintain rail-to-rail output capability and operate within the supply voltage range of 2.7 V to 16 V. Input bias current, input offset voltage, slew rate, and gain bandwidth product define the analog performance envelope.

Operating Temperature Range: The main part operates from -40°C to 125°C. Substitute parts must support this full temperature range or a subset thereof, depending on application requirements.

Compliance & Certification: All parts must maintain ROHS3 compliance, MSL Level 1 rating, and REACH unaffected status to ensure regulatory and environmental compatibility.

The substitute parts identified below meet these criteria with documented electrical and mechanical equivalence.

Parameter Comparison

Engineering Selection Recommendations

TLV2371IDR (Primary Substitute): This Texas Instruments part is the direct functional equivalent of the TLV2371IDRG4. It maintains identical electrical specifications, package configuration, and operating temperature range. The TLV2371IDR carries active product status, ensuring long-term availability and supply chain stability. This part is the preferred substitute for direct replacement in existing designs.

TLV271IS-13 (Secondary Substitute): Manufactured by Diodes Incorporated, this CMOS amplifier operates across the full temperature range (-40°C to 125°C) matching the main part. It provides lower input offset voltage (500 µV vs. 2 mV) and reduced supply current (550 µA vs. 750 µA), offering improved precision and power efficiency. The trade-off is reduced output current capability (8 mA vs. 16 mA) and slightly lower gain bandwidth product (1.9 MHz vs. 3 MHz). This part is suitable for applications where lower power consumption and improved offset characteristics are beneficial and output current requirements do not exceed 8 mA.

TLV271CS-13 (Tertiary Substitute): Also from Diodes Incorporated, this CMOS amplifier shares electrical characteristics with the TLV271IS-13 but operates only across the commercial temperature range (0°C to 70°C). Selection of this part is restricted to applications that do not require extended low-temperature operation below 0°C or high-temperature operation above 70°C. Active product status ensures availability.

All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and REACH unaffected status, ensuring regulatory and environmental compatibility with the original design.

Frequently Asked Questions (FAQ)

Q: Can TLV2371IDR be used as a direct replacement for TLV2371IDRG4?

A: Yes. The TLV2371IDR is electrically and mechanically identical to the TLV2371IDRG4. Both parts share the same base product number (TLV2371), identical electrical specifications, and 8-SOIC package. The primary difference is product status: TLV2371IDR is active, while TLV2371IDRG4 is obsolete. No circuit modifications are required.

Q: What are the key differences between TLV2371IDRG4 and the Diodes Incorporated TLV271 series?

A: The TLV271 series (TLV271IS-13 and TLV271CS-13) are CMOS amplifiers with lower input offset voltage (500 µV vs. 2 mV) and reduced supply current (550 µA vs. 750 µA). However, they provide lower output current per channel (8 mA vs. 16 mA) and slightly reduced gain bandwidth product. Both maintain rail-to-rail output and the same supply voltage range. The TLV271IS-13 supports the full temperature range (-40°C to 125°C), while TLV271CS-13 is limited to 0°C to 70°C.

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

A: Yes. All substitute parts use the 8-SOIC surface-mount package with 0.154" (3.90mm) width, ensuring PCB footprint compatibility without layout modifications.

Q: Which substitute part should I select for a low-power application?

A: The TLV271IS-13 or TLV271CS-13 are preferred for low-power applications, as they consume 550 µA compared to 750 µA for the main part and TLV2371IDR. However, verify that the reduced output current capability (8 mA vs. 16 mA) meets your circuit requirements.

Q: Can TLV271CS-13 be used in applications requiring -40°C operation?

A: No. The TLV271CS-13 operates only from 0°C to 70°C. For applications requiring operation below 0°C, use TLV271IS-13 or TLV2371IDR, both of which support -40°C to 125°C.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts (TLV2371IDR, TLV271IS-13, and TLV271CS-13) are ROHS3 compliant with MSL Level 1 rating and REACH unaffected status.

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

A: The primary difference is operating temperature range. TLV271IS-13 operates from -40°C to 125°C (industrial grade), while TLV271CS-13 operates from 0°C to 70°C (commercial grade). All other electrical specifications are identical. Select based on your application's temperature requirements.
