TLE2024AIDW Equivalent & Substitute Parts

Part Overview

The TLE2024AIDW is a general-purpose operational amplifier featuring four independent circuits in a 16-SOIC surface mount 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 TLE2024AIDW operates across a wide supply voltage range of 4V to 40V and is suitable for applications requiring low input bias current and moderate bandwidth performance. 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 of the TLE2024AIDW is determined by the following critical parameters that must remain consistent across equivalent parts:

Mandatory Matching Parameters:

• Amplifier Type: General Purpose
• Number of Circuits: 4
• Package / Case: 16-SOIC (0.295", 7.50mm Width)
• Mounting Type: Surface Mount
• Gain Bandwidth Product: 2.8 MHz
• Current - Input Bias: 45 nA
• Current - Supply: 1.05 mA (x4 Channels)
• Current - Output / Channel: 40 mA
• Voltage - Supply Span: 4 V to 40 V
• RoHS Status: ROHS3 Compliant

Allowable Parameter Variations: Substitute parts may exhibit differences in slew rate, input offset voltage, and operating temperature range while maintaining functional equivalence within the specified application envelope.

The TLE2024CDWR is identified as the manufacturer-recommended substitute, sharing identical core electrical specifications and package configuration while differing in product status (Active vs. Last Time Buy) and packaging format (Cut Tape & Digi-Reel® vs. Tube).

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TLE2024CDWR

The TLE2024CDWR is the manufacturer-recommended equivalent for the TLE2024AIDW. Both devices share identical core electrical specifications including gain bandwidth product, input bias current, supply current, and output current capacity. The TLE2024CDWR maintains ROHS3 compliance and unlimited moisture sensitivity rating, ensuring regulatory and environmental compatibility.

Key Differences:

The TLE2024CDWR operates within a narrower temperature range (0°C to 70°C) compared to the TLE2024AIDW (-40°C to 85°C). Applications requiring extended low-temperature operation below 0°C or high-temperature operation above 70°C must account for this limitation. The TLE2024CDWR exhibits a lower slew rate (0.5 V/µs vs. 0.7 V/µs) and higher input offset voltage (1 mV vs. 80 µV), which may impact performance in high-speed or precision signal conditioning applications.

Availability and Status:

The TLE2024CDWR is currently in Active production status with significantly higher inventory availability (2968 Pcs) compared to the Last Time Buy TLE2024AIDW (746 Pcs). The TLE2024CDWR is supplied in Cut Tape and Digi-Reel® formats, offering flexibility for both prototype and production volume requirements.

Compliance Certification:

Both devices maintain identical compliance certifications: ROHS3 Compliant, REACH Unaffected, and EAR99 export classification. No additional regulatory review is required when transitioning from TLE2024AIDW to TLE2024CDWR.

Frequently Asked Questions (FAQ)

Q: Can the TLE2024CDWR directly replace the TLE2024AIDW in all applications?

A: The TLE2024CDWR is electrically equivalent for applications operating within the 0°C to 70°C temperature range. Applications requiring operation below 0°C or above 70°C must use the TLE2024AIDW or identify alternative solutions. The lower slew rate and higher input offset voltage of the TLE2024CDWR may require circuit re-evaluation in high-speed or precision applications.

Q: What is the significance of the Last Time Buy status for the TLE2024AIDW?

A: Last Time Buy designation indicates that Texas Instruments has discontinued production of the TLE2024AIDW. Current inventory (746 Pcs) represents the final available stock. Once depleted, the device will no longer be available from the manufacturer. The TLE2024CDWR is the recommended transition path for new designs and ongoing production requirements.

Q: Are there differences in package handling or storage between TLE2024AIDW and TLE2024CDWR?

A: Both devices share identical moisture sensitivity level (MSL 1 - Unlimited), indicating no special moisture control requirements during storage or handling. The primary packaging difference is format: TLE2024AIDW is supplied in Tube packaging, while TLE2024CDWR is available in Cut Tape and Digi-Reel® formats. This affects component feeding and assembly processes but does not impact device performance or reliability.

Q: How do the electrical parameter differences affect circuit design?

A: The TLE2024CDWR's lower slew rate (0.5 V/µs vs. 0.7 V/µs) may limit maximum signal frequency in transient-response-sensitive applications. The higher input offset voltage (1 mV vs. 80 µV) requires consideration in precision DC amplification circuits. Both parameters remain within acceptable ranges for general-purpose amplifier applications. Circuit simulation or bench testing is appropriate for applications with tight performance margins.

Q: What packaging options are available for the TLE2024CDWR?

A: The TLE2024CDWR is supplied in Cut Tape (CT) and Digi-Reel® formats, enabling compatibility with automated component placement equipment. The TLE2024AIDW Tube packaging is suitable for manual assembly or lower-volume production. Both formats contain identical devices in the same 16-SOIC package.

Q: Are there supply voltage or current consumption differences between the two parts?

A: No. Both the TLE2024AIDW and TLE2024CDWR operate across the identical 4V to 40V supply voltage range with identical supply current consumption (1.05 mA per four channels) and output current capability (40 mA per channel). Power supply design and component selection remain unchanged when substituting between these devices.
