TLV2401CD Equivalent & Substitute Parts

Part Overview

The TLV2401CD is a general-purpose operational amplifier manufactured by Texas Instruments, featuring rail-to-rail output capability in an 8-SOIC surface mount package. This device is classified as Last Time Buy, indicating discontinued production with limited inventory availability. The TLV2401CD serves applications requiring low-power, single-circuit amplification with supply voltage flexibility across 2.5V to 16V operating ranges.

Identifying equivalent and substitute parts is necessary due to the Last Time Buy status, which restricts long-term procurement availability. Alternative components with compatible electrical and mechanical specifications ensure design continuity and supply chain reliability.

Engineering Selection Recommendations

TLV2401IDR Selection Criteria:

TLV2401IDR is the primary substitute for TLV2401CD applications. Both components share identical electrical specifications and package configuration. TLV2401IDR maintains Active product status, ensuring continued availability and supply chain stability. The extended operating temperature range (-40°C to 125°C) provides broader environmental compatibility compared to the TLV2401CD (0°C to 70°C). Packaging format differs (Tape & Reel vs. Tube), which affects procurement and handling but does not impact electrical performance or circuit functionality. ROHS3 compliance and MSL rating remain equivalent.

TLV271CS-13 and TLV271IS-13 Selection Criteria:

TLV271 series components (both CS-13 and IS-13 variants) are functionally compatible substitutes with significant performance enhancements. Both maintain 8-SOIC package compatibility and rail-to-rail output configuration. Key electrical differences include substantially higher slew rate (2V/µs vs. 0.0025V/µs), higher gain bandwidth product (approximately 2MHz vs. 5.5kHz), and lower input bias current (1pA vs. 100pA). These characteristics indicate suitability for applications requiring faster signal response and higher frequency operation.

TLV271IS-13 offers extended operating temperature range (-40°C to 125°C) and Active product status, providing superior long-term availability. TLV271CS-13 maintains the original temperature range (0°C to 70°C) matching TLV2401CD specifications. Both variants are ROHS3 compliant with MSL rating of 1 (Unlimited).

Selection between TLV271CS-13 and TLV271IS-13 depends on application temperature requirements. Selection between TLV2401IDR and TLV271 series depends on required bandwidth and slew rate performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can TLV2401IDR directly replace TLV2401CD in existing designs?

A: Yes. TLV2401IDR provides electrical equivalence with identical specifications for amplifier type, output type, slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current, and supply voltage range. The 8-SOIC package and surface mount configuration are identical. Packaging format (Tape & Reel vs. Tube) affects procurement logistics but not circuit performance.

Q: What are the key differences between TLV2401CD and TLV271 series substitutes?

A: TLV271 series components (CS-13 and IS-13) are CMOS amplifiers with significantly higher performance specifications. Slew rate increases from 0.0025V/µs to 2V/µs. Gain bandwidth product increases from 5.5kHz to approximately 2MHz. Input bias current decreases from 100pA to 1pA. Output current capability increases from 200µA to 8mA. Supply current increases from 900nA to 550µA. These differences indicate TLV271 series suitability for higher-frequency and higher-speed applications.

Q: Are TLV271CS-13 and TLV271IS-13 interchangeable?

A: Both components share identical electrical specifications and package configuration. The primary difference is operating temperature range: TLV271CS-13 operates 0°C to 70°C, while TLV271IS-13 operates -40°C to 125°C. Selection depends on application temperature requirements. Both maintain Active product status and ROHS3 compliance.

Q: What supply voltage compatibility exists across all substitute options?

A: TLV2401CD and TLV2401IDR support 2.5V to 16V supply range. TLV271CS-13 and TLV271IS-13 support 2.7V to 16V supply range. Applications requiring operation below 2.7V must use TLV2401 series components. All variants support the full 16V maximum specification.

Q: How does the Last Time Buy status of TLV2401CD affect substitution decisions?

A: Last Time Buy status indicates discontinued production with limited inventory. TLV2401IDR, TLV271CS-13, and TLV271IS-13 all maintain Active product status, ensuring long-term availability. For new designs or applications requiring extended component availability, Active status substitutes are preferred. For existing inventory management, TLV2401IDR provides direct electrical equivalence.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. TLV2401CD, TLV2401IDR, TLV271CS-13, and TLV271IS-13 are all ROHS3 compliant with MSL rating of 1 (Unlimited). Regulatory compliance is maintained across all substitute options.
