TLE2024IN Equivalent & Substitute Parts

Part Overview

The TLE2024IN 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 inventory availability. The TLE2024IN operates across a wide supply voltage range (4V to 40V) and is suitable for applications requiring moderate bandwidth and low input bias current in legacy or through-hole based designs. Due to its Last Time Buy status, identifying functionally equivalent substitute parts is essential for design continuity and long-term component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLE2024IN is determined by the following critical parameters:

Primary Substitution Criteria:

• Number of circuits: 4 independent amplifier channels
• Amplifier type: General-purpose operational amplifier topology
• Supply voltage range compatibility: Minimum 4V, maximum 40V
• Slew rate: 0.5 V/µs or greater
• Gain bandwidth product: 2.8 MHz or greater
• Input bias current: 45 nA or lower
• Output current capability: 40 mA per channel or greater
• Package compatibility: Through-hole 14-DIP or surface-mount equivalents with identical pin functionality

Secondary Considerations:

• Operating temperature range: Extended range (-40°C to 85°C) preferred for industrial applications
• RoHS3 compliance and REACH unaffected status for regulatory alignment
• Product status: Active or Last Time Buy acceptable; obsolete parts excluded

The TLE2024CDWR (Texas Instruments) serves as the manufacturer-recommended direct substitute, offering identical electrical performance in a surface-mount 16-SOIC package. The LT1465CN (Analog Devices) represents a functional alternative with J-FET input architecture, providing superior input bias current characteristics at the cost of reduced supply voltage range and different thermal performance.

Parameter Comparison

Engineering Selection Recommendations

TLE2024CDWR Selection Criteria:

The TLE2024CDWR is the manufacturer-recommended substitute for the TLE2024IN and maintains identical electrical specifications across all critical parameters: slew rate, gain bandwidth product, input bias current, supply current, and output current capability. Both devices operate within the 4V to 40V supply range and are ROHS3 compliant. The primary distinction is packaging: TLE2024CDWR uses 16-SOIC surface-mount technology versus the through-hole 14-DIP of the TLE2024IN. This substitute is appropriate for new designs or redesigns where surface-mount assembly is feasible. The TLE2024CDWR maintains Active product status, ensuring long-term availability and supply chain stability.

LT1465CN Selection Criteria:

The LT1465CN represents a functional alternative for applications where input bias current minimization is critical. Its J-FET input architecture delivers 0.5 pA input bias current compared to 45 nA in the TLE2024IN, a significant advantage for high-impedance signal conditioning. However, the LT1465CN operates within a narrower supply voltage range (10V to 30V minimum versus 4V to 40V), making it unsuitable for applications requiring extended low-voltage operation below 10V. The LT1465CN also exhibits reduced gain bandwidth product (1 MHz versus 2.8 MHz) and lower slew rate (0.9 V/µs versus 0.5 V/µs, though this is an improvement). Operating temperature range is limited to 0°C to 70°C, restricting use in extended industrial temperature applications. The LT1465CN maintains through-hole 14-DIP packaging, preserving board-level compatibility. This substitute is appropriate for precision analog applications where input bias current dominates system performance and supply voltage constraints are acceptable.

Product Status Consideration:

The TLE2024IN is Last Time Buy, indicating production discontinuation. The TLE2024CDWR (Active status) is the preferred long-term substitute for ongoing production and new designs. The LT1465CN (Active status) serves as a secondary alternative for specialized applications with different electrical requirements.

Frequently Asked Questions (FAQ)

Q1: Can the TLE2024CDWR directly replace the TLE2024IN in existing through-hole PCB designs?

A: Electrical substitution is complete; however, package conversion is required. The TLE2024CDWR uses 16-SOIC surface-mount packaging while the TLE2024IN uses 14-DIP through-hole. Direct socket replacement is not possible without PCB redesign or use of an adapter carrier. For through-hole designs requiring minimal modification, the LT1465CN maintains 14-DIP packaging but introduces different electrical characteristics.

Q2: What are the key electrical differences between TLE2024IN and LT1465CN?

A: The LT1465CN offers superior input bias current (0.5 pA versus 45 nA) due to J-FET input architecture, making it preferable for high-impedance applications. Conversely, the LT1465CN operates within a narrower supply voltage range (10V to 30V versus 4V to 40V), lower gain bandwidth product (1 MHz versus 2.8 MHz), and restricted operating temperature range (0°C to 70°C versus -40°C to 85°C). Supply current is significantly lower (145 µA versus 1.05 mA for four channels).

Q3: Is the TLE2024IN suitable for new designs, or should substitutes be used?

A: The TLE2024IN is Last Time Buy status, indicating production discontinuation. New designs should utilize the TLE2024CDWR (manufacturer-recommended, Active status) or LT1465CN (alternative, Active status) to ensure long-term component availability and supply chain continuity.

Q4: What compliance certifications apply to all three parts?

A: All three parts (TLE2024IN, TLE2024CDWR, and LT1465CN) are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for industrial and commercial applications.

Q5: Can the LT1465CN operate from a 5V single supply like the TLE2024IN?

A: No. The LT1465CN requires a minimum supply voltage of 10V, making it incompatible with 5V single-supply applications. The TLE2024IN and TLE2024CDWR both operate from 4V minimum, supporting standard 5V logic supply rails.

Q6: Which substitute is recommended for precision instrumentation applications?

A: The LT1465CN is recommended for precision instrumentation where input bias current is the dominant error source. Its 0.5 pA input bias current is approximately 90 times lower than the TLE2024IN, significantly improving measurement accuracy in high-impedance circuits. Verify that the 10V to 30V supply voltage range and 0°C to 70°C operating temperature range meet application requirements.

Q7: Are there inventory considerations when selecting a substitute?

A: The TLE2024CDWR has higher inventory availability (2968 pcs) compared to the TLE2024IN (1437 pcs, Last Time Buy). For long-term production, the TLE2024CDWR is the preferred choice due to Active product status and superior supply chain stability.
