TLE2021ID Equivalent & Substitute Parts

Part Overview

The TLE2021ID is a general-purpose operational amplifier manufactured by Texas Instruments, housed in an 8-SOIC surface mount package. This device is classified as a Last Time Buy product, indicating that the original packaging configuration (Tube) is no longer in active production. The TLE2021ID belongs to the Excalibur™ series and is designed for applications requiring low-power, general-purpose amplification with a gain bandwidth product of 2 MHz and a slew rate of 0.65 V/µs.

Identification of equivalent and substitute parts becomes necessary when the original packaging format is discontinued or when inventory availability requires sourcing from alternative packaging configurations. Substitute parts maintain identical electrical performance and mechanical compatibility while offering different packaging or availability status.

Substitute Part Grouping Explanation

Substitution of the TLE2021ID is determined by strict equivalence across all electrical and mechanical parameters. The primary substitute identified is the TLE2021IDR, which maintains identical specifications across all performance characteristics while differing only in packaging configuration.

The substitution logic is based on the following criteria:

• Amplifier Type: Must be General Purpose
• Number of Circuits: Must be 1
• Slew Rate: Must equal 0.65 V/µs
• Gain Bandwidth Product: Must equal 2 MHz
• Current - Input Bias: Must equal 25 nA
• Voltage - Input Offset: Must equal 120 µV
• Current - Supply: Must equal 240 µA
• Current - Output / Channel: Must equal 20 mA
• Voltage - Supply Span: Must support 4 V to 40 V range
• Operating Temperature Range: Must support -40°C to 85°C
• Package / Case: Must be 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Must be Surface Mount
• RoHS and REACH Compliance: Must maintain ROHS3 Compliant and REACH Unaffected status

Parameter Comparison

Engineering Selection Recommendations

The TLE2021IDR is the direct equivalent substitute for the TLE2021ID. Both devices are manufactured by Texas Instruments and share identical electrical specifications, performance characteristics, and mechanical compatibility. The distinction between these parts lies exclusively in packaging configuration and product status.

The TLE2021ID is designated as Last Time Buy, indicating that the tube packaging format is being discontinued. The TLE2021IDR, available in Cut Tape and Digi-Reel® packaging, maintains Active product status and represents the current production configuration for this device.

Both parts maintain full compliance with ROHS3 and REACH requirements, ensuring regulatory compatibility for applications subject to environmental and hazardous substance restrictions. The identical electrical parameters guarantee functional interchangeability in all circuit applications where the TLE2021ID was originally specified.

Selection between these parts should be based on packaging requirements and inventory availability. The TLE2021IDR is suitable for high-volume automated assembly processes utilizing tape-and-reel feeding systems, while the TLE2021ID in tube packaging may be appropriate for lower-volume or manual assembly operations where inventory remains available.

Frequently Asked Questions (FAQ)

Q: Are the TLE2021ID and TLE2021IDR electrically identical?

A: Yes. Both devices share identical electrical specifications, including slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current capability, and operating temperature range. They are functionally equivalent in all circuit applications.

Q: What is the primary difference between TLE2021ID and TLE2021IDR?

A: The primary difference is packaging format. The TLE2021ID is supplied in Tube packaging, while the TLE2021IDR is supplied in Cut Tape and Digi-Reel® packaging. Additionally, the TLE2021ID carries Last Time Buy status, while the TLE2021IDR is Active.

Q: Can I use TLE2021IDR as a direct replacement for TLE2021ID in my circuit design?

A: Yes. The TLE2021IDR is a direct substitute for the TLE2021ID. All electrical parameters, mechanical dimensions, and pin configurations are identical. No circuit modifications are required.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the TLE2021ID and TLE2021IDR are ROHS3 Compliant and REACH Unaffected, meeting environmental and regulatory requirements for restricted substance use.

Q: What does Last Time Buy status mean for the TLE2021ID?

A: Last Time Buy status indicates that the TLE2021ID in tube packaging is being discontinued. Existing inventory may be available, but future production in this packaging format is not planned. The TLE2021IDR in alternative packaging remains in active production.

Q: Are the pin configurations identical between these parts?

A: Yes. Both devices use the 8-SOIC package with identical pin assignments and mechanical dimensions (0.154" width, 3.90mm width). They are pin-for-pin compatible.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without moisture control requirements.

Q: Which packaging format is better for automated assembly?

A: The TLE2021IDR in Cut Tape and Digi-Reel® packaging is optimized for automated pick-and-place assembly systems. The TLE2021ID in tube packaging is suitable for manual or semi-automated assembly processes.
