TLE2022CD Equivalent & Substitute Parts

Part Overview

The TLE2022CD is a general-purpose operational amplifier featuring dual circuits in an 8-SOIC surface mount package, manufactured by Texas Instruments under the Excalibur™ series. This device is designated as Last Time Buy, indicating discontinued production with limited inventory availability. The TLE2022CD operates across a wide supply voltage range of 4V to 40V and is suitable for applications requiring general-purpose amplification with moderate performance specifications. Due to its Last Time Buy status, identifying equivalent and substitute parts is essential for design continuity and long-term component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLE2022CD is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Dual-circuit operational amplifier configuration (2 circuits minimum)
• 8-SOIC surface mount package with 0.154" (3.90mm) width
• Supply voltage range compatibility: minimum 4V, maximum 40V
• ROHS3 compliance and EAR99 classification
• Operating temperature range: devices must support at least 0°C to 70°C

Secondary Compatibility Parameters:

• Slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, and output current per channel determine functional equivalence within application-specific requirements
• Packaging format (Tube, Cut Tape, or Digi-Reel) does not affect electrical substitution but affects procurement and handling

The substitute parts identified—TLE2022CDR, ISL28207FBZ, and ISL28227FBZ—all meet the primary substitution criteria. Variations in secondary parameters indicate performance differences that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

TLE2022CDR (Texas Instruments)

The TLE2022CDR is the direct equivalent of the TLE2022CD, offering identical electrical specifications and performance characteristics. This part maintains Active product status, ensuring long-term availability and supply chain stability. The TLE2022CDR is supplied in Cut Tape and Digi-Reel packaging formats, providing flexibility for both prototype and production environments. Selection of TLE2022CDR is recommended as the primary substitute for applications currently using TLE2022CD, as it eliminates any performance variation while maintaining design compatibility.

ISL28207FBZ (Renesas Electronics Corporation)

The ISL28207FBZ is a functionally compatible substitute with reduced power consumption (210µA vs. 550µA supply current) and superior input characteristics (15pA input bias current, 5µV input offset voltage). This device operates across an extended temperature range (-40°C to 125°C) compared to the TLE2022CD (0°C to 70°C). The ISL28207FBZ exhibits lower slew rate (0.32V/µs) and reduced gain bandwidth product (1MHz), making it suitable for applications where power efficiency and precision are prioritized over high-speed performance. Minimum supply voltage requirement is 4.5V, which may limit compatibility in systems operating below this threshold.

ISL28227FBZ (Renesas Electronics Corporation)

The ISL28227FBZ is a high-performance substitute featuring significantly enhanced slew rate (3.6V/µs) and gain bandwidth product (10MHz), with exceptional input bias current (1nA) and input offset voltage (10µV). This device supports extended operating temperature range (-40°C to 125°C) and higher output current per channel (45mA). The ISL28227FBZ exhibits elevated supply current consumption (2.2mA), which may impact power budget in battery-operated or low-power applications. Minimum supply voltage requirement is 4.5V. Selection is appropriate for applications requiring superior dynamic performance and precision.

All substitute parts maintain ROHS3 compliance, EAR99 classification, and 8-SOIC package compatibility with the original TLE2022CD.

Frequently Asked Questions (FAQ)

Q1: Can TLE2022CDR be used as a direct replacement for TLE2022CD?

A: Yes. The TLE2022CDR is electrically and mechanically identical to the TLE2022CD. Both devices share identical slew rate (0.65V/µs), gain bandwidth product (2.8MHz), input bias current (35nA), input offset voltage (150µV), supply current (550µA per dual channels), output current (30mA per channel), and supply voltage range (4V to 40V). The only difference is product status (Active vs. Last Time Buy) and packaging format (Cut Tape/Digi-Reel vs. Tube). TLE2022CDR is the recommended substitute for long-term design continuity.

Q2: What are the key differences between ISL28207FBZ and ISL28227FBZ?

A: Both Renesas devices are functionally compatible with the TLE2022CD in terms of package and pin configuration. ISL28207FBZ prioritizes power efficiency with 210µA supply current and superior precision (15pA input bias, 5µV offset), but operates at lower speed (0.32V/µs slew rate, 1MHz bandwidth). ISL28227FBZ prioritizes performance with 3.6V/µs slew rate and 10MHz bandwidth, but consumes higher power (2.2mA supply current). Selection depends on application requirements for speed versus power consumption.

Q3: Are there temperature range limitations when substituting with Renesas devices?

A: The TLE2022CD operates from 0°C to 70°C. Both ISL28207FBZ and ISL28227FBZ operate from -40°C to 125°C, providing extended temperature coverage. However, if the application requires operation only within the 0°C to 70°C range, the extended temperature capability of Renesas devices does not provide additional benefit. Conversely, applications requiring operation below 0°C or above 70°C cannot use the TLE2022CD or TLE2022CDR and must select ISL28207FBZ or ISL28227FBZ.

Q4: What is the significance of the 4.5V minimum supply voltage for Renesas devices?

A: The TLE2022CD and TLE2022CDR support minimum supply voltage of 4V. Both Renesas substitutes (ISL28207FBZ and ISL28227FBZ) require minimum 4.5V. In applications operating at 4V to 4.4V supply voltage, only TLE2022CD or TLE2022CDR are compatible. For systems with 4.5V or higher supply voltage, all devices are compatible.

Q5: How do moisture sensitivity levels affect component handling?

A: The TLE2022CD and TLE2022CDR have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture-related storage restrictions. Both Renesas devices (ISL28207FBZ and ISL28227FBZ) have Moisture Sensitivity Level 2 (1 Year), requiring controlled storage conditions and limiting shelf life to one year from manufacturing date. This affects procurement planning, inventory management, and component handling procedures.

Q6: Are all substitute parts available in the same packaging formats?

A: No. The TLE2022CD is supplied in Tube packaging. The TLE2022CDR is available in Cut Tape and Digi-Reel formats. ISL28207FBZ packaging format is not specified in the provided data. ISL28227FBZ is supplied in Tube packaging. Packaging format affects procurement logistics but does not impact electrical compatibility or circuit performance.

Q7: Which substitute should be selected for low-power applications?

A: The ISL28207FBZ is the optimal choice for power-constrained applications, consuming only 210µA supply current compared to 550µA for TLE2022CD/TLE2022CDR and 2.2mA for ISL28227FBZ. This represents a 62% reduction in power consumption relative to the original device.

Q8: Which substitute should be selected for high-speed signal processing?

A: The ISL28227FBZ is the optimal choice for applications requiring high-speed performance, offering 3.6V/µs slew rate and 10MHz gain bandwidth product compared to 0.65V/µs and 2.8MHz for the TLE2022CD. This represents approximately 5.5× improvement in slew rate and 3.6× improvement in bandwidth.
