TLE2024AIN Equivalent & Substitute Parts Reference

Part Overview

The TLE2024AIN is a general-purpose operational amplifier featuring four independent circuits in a 14-DIP through-hole package, manufactured by Texas Instruments under the Excalibur™ series. This device is classified as Last Time Buy, indicating discontinued production with limited availability. The TLE2024AIN operates across a wide supply voltage range of 4V to 40V and is suitable for applications requiring moderate bandwidth and low input bias current characteristics.

Identifying equivalent and substitute parts is necessary due to the Last Time Buy status of the TLE2024AIN. Alternative configurations and manufacturers offer functionally compatible solutions with different packaging options, performance characteristics, and current availability to support ongoing design requirements and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLE2024AIN is determined by the following critical parameters:

Functional Equivalence Criteria:

• Number of circuits: 4 independent amplifier channels
• Amplifier type: General-purpose operational amplifier topology
• Supply voltage range compatibility: Minimum 4V to maximum 40V operation
• Output current capability: 40 mA per channel
• Package pin count and functional pinout compatibility

Substitution Categories:

Category 1: Same Manufacturer, Different Package (Texas Instruments) The TLE2024ACDWR maintains identical electrical specifications (0.7V/µs slew rate, 2.8 MHz gain bandwidth product, 45 nA input bias current, 750 µV input offset voltage) but differs in packaging format (16-SOIC surface mount versus 14-DIP through hole) and operating temperature range (0°C ~ 70°C versus -40°C ~ 85°C). This substitute is suitable for applications where surface-mount assembly is preferred and the narrower temperature range is acceptable.

Category 2: Alternative Manufacturer, Different Amplifier Type (Analog Devices Inc.) The LT1058ACN#PBF is a J-FET input amplifier from Analog Devices Inc., maintaining the 14-DIP through-hole package format but introducing different electrical characteristics: 14V/µs slew rate (20× faster), 5 MHz gain bandwidth product (1.79× higher), and 5 pA input bias current (9000× lower). The supply voltage range differs (20V to 36V minimum/maximum versus 4V to 40V), and operating temperature is 0°C ~ 70°C. This substitute is applicable when superior input bias current performance and higher bandwidth are required within the constrained supply voltage range.

Engineering Selection Recommendations

TLE2024ACDWR Selection Criteria: The TLE2024ACDWR is the manufacturer-recommended substitute from Texas Instruments, maintaining complete electrical equivalence to the TLE2024AIN. This part is classified as Active product status, ensuring long-term availability and supply continuity. Selection of TLE2024ACDWR is appropriate when:

• Surface-mount assembly processes are employed
• Operating temperature range of 0°C ~ 70°C satisfies application requirements
• The 16-SOIC package footprint is compatible with PCB layout constraints
• ROHS3 compliance and REACH unaffected status are required

LT1058ACN#PBF Selection Criteria: The LT1058ACN#PBF from Analog Devices Inc. is an alternative substitute suitable for applications requiring superior input bias current performance (5 pA versus 45 nA) and higher slew rate (14V/µs versus 0.7V/µs). This part maintains Active product status and ROHS3 compliance. Selection of LT1058ACN#PBF is appropriate when:

• J-FET input amplifier characteristics are beneficial for the application
• Supply voltage operation falls within the 20V to 36V range
• Operating temperature range of 0°C ~ 70°C is acceptable
• Through-hole mounting in 14-DIP package is required
• Higher bandwidth (5 MHz) and lower input bias current are design priorities

Compliance Verification: All three parts (TLE2024AIN, TLE2024ACDWR, LT1058ACN#PBF) maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for electronic component procurement.

Frequently Asked Questions (FAQ)

Q1: Can TLE2024ACDWR directly replace TLE2024AIN in existing through-hole PCB designs?

A: No. The TLE2024ACDWR uses a 16-SOIC surface-mount package, while the TLE2024AIN uses a 14-DIP through-hole package. Direct PCB substitution is not possible without redesigning the board layout and assembly process. However, the electrical specifications are identical, making it suitable for new designs or board revisions that accommodate surface-mount assembly.

Q2: What are the key differences between TLE2024AIN and LT1058ACN#PBF?

A: The primary differences are amplifier type (general-purpose CMOS versus J-FET input), slew rate (0.7V/µs versus 14V/µs), input bias current (45 nA versus 5 pA), and supply voltage range (4V–40V versus 20V–36V). The LT1058ACN#PBF offers superior input bias current and slew rate performance but operates within a narrower supply voltage range. Both maintain the 14-DIP through-hole package format.

Q3: Is the LT1058ACN#PBF suitable for low-voltage applications below 20V?

A: No. The LT1058ACN#PBF requires a minimum supply voltage of 20V, making it unsuitable for applications operating below this threshold. The TLE2024AIN and TLE2024ACDWR support supply voltages as low as 4V and are appropriate for low-voltage designs.

Q4: What is the impact of the narrower operating temperature range in TLE2024ACDWR and LT1058ACN#PBF?

A: Both substitute parts operate from 0°C ~ 70°C, compared to the TLE2024AIN range of -40°C ~ 85°C. Applications requiring operation below 0°C or above 70°C must use the TLE2024AIN. Industrial and automotive applications with extended temperature requirements should verify compatibility before substitution.

Q5: Are all three parts RoHS3 compliant?

A: Yes. The TLE2024AIN, TLE2024ACDWR, and LT1058ACN#PBF are all ROHS3 compliant and REACH unaffected, meeting regulatory requirements for electronic component procurement in regulated markets.

Q6: Why does the TLE2024AIN have Last Time Buy status?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of the TLE2024AIN. The TLE2024ACDWR (same base product in different packaging) and alternative manufacturers' products (such as LT1058ACN#PBF) are recommended for new designs and long-term production continuity.

Q7: Can the input bias current difference between TLE2024AIN (45 nA) and LT1058ACN#PBF (5 pA) affect circuit performance?

A: Yes. The 9000× lower input bias current of the LT1058ACN#PBF reduces errors in high-impedance circuits and precision applications. Applications with input impedances exceeding 1 MΩ benefit from the J-FET input characteristics of the LT1058ACN#PBF. Standard applications with lower impedance sources may not require this performance advantage.
