Substitute Part Grouping Explanation
Substitute parts for the TLE2022MDR are identified based on the following electrical and mechanical compatibility criteria:
Primary Substitution Criteria:
- Number of Circuits: 2 (dual-channel configuration)
- Package Type: 8-SOIC surface mount (0.154", 3.90mm Width) for direct pin-compatible replacement
- Voltage Supply Range: Minimum 4V to 5V, Maximum 36V to 40V
- Operating Temperature Range: Support for -40°C to 125°C or extended range
- Product Status: Active
- RoHS3 Compliance: Required
Substitution Logic:
Substitute parts are grouped into two categories based on amplifier type and performance characteristics:
-
Voltage Feedback Amplifiers (AD826 Series): These devices provide higher slew rate (350V/µs) and gain bandwidth product (50 MHz) compared to the TLE2022MDR. The AD826 series is available in multiple packaging options including 8-DIP through-hole and 8-SOIC surface mount variants. These substitutes are suitable for applications requiring enhanced bandwidth performance while maintaining dual-circuit configuration and compatible supply voltage ranges.
-
J-FET Amplifiers (ADTL082 Series): These devices feature extremely low input bias current (2 pA) and are available in 8-SOIC and 8-MSOP surface mount packages. The ADTL082 series operates across the extended temperature range (-40°C to 125°C) and maintains dual-circuit configuration with compatible supply voltage specifications.
-
General Purpose Amplifiers (ISL28227 Series): This device maintains the general purpose amplifier classification with improved specifications including lower input offset voltage (10 µV) and higher gain bandwidth product (10 MHz). The ISL28227FBZ is available in 8-SOIC surface mount package with compatible supply voltage range and extended operating temperature support.
All substitute parts maintain RoHS3 compliance and MSL rating compatibility with the original TLE2022MDR device.

Engineering Selection Recommendations
Direct Pin-Compatible Substitutes (8-SOIC Surface Mount):
The following parts provide direct pin-compatible replacement in the 8-SOIC surface mount package: AD826ARZ, AD826ARZ-REEL, AD826ARZ-REEL7, ADTL082ARZ, ADTL082ARZ-REEL, ADTL082ARZ-REEL7, and ISL28227FBZ. These devices maintain the same physical footprint (0.154", 3.90mm Width) and surface mount configuration as the TLE2022MDR, enabling direct PCB layout compatibility.
Packaging Variants:
The AD826ANZ provides an 8-DIP through-hole package alternative, suitable for applications requiring through-hole mounting technology. The ADTL082ARMZ and ADTL082ARMZ-REEL offer 8-MSOP surface mount packages (0.118", 3.00mm Width), which provide a smaller footprint than the standard 8-SOIC package.
Supply Voltage Considerations:
The TLE2022MDR operates with a minimum supply voltage of 4V. Substitute parts AD826 series devices require a minimum of 5V, while ADTL082 series devices require a minimum of 8V. The ISL28227FBZ operates at a minimum of 4.5V. Applications with supply voltages below 5V must use either the TLE2022MDR or ISL28227FBZ.
Operating Temperature Range:
The TLE2022MDR supports an extended operating temperature range of -55°C to 125°C. The AD826 series is limited to -40°C to 85°C. The ADTL082 series and ISL28227FBZ support -40°C to 125°C. Applications requiring operation below -40°C must use the TLE2022MDR.
Compliance and Certifications:
All substitute parts maintain RoHS3 compliance and REACH Unaffected status, consistent with the TLE2022MDR. The TLE2022MDR and all substitute parts carry MSL rating of 1 (Unlimited) except ISL28227FBZ, which carries MSL rating of 2 (1 Year). The ISL28227FBZ requires controlled moisture handling with a one-year shelf life limitation.
Inventory Availability:
Current inventory levels are provided for all substitute parts. The ADTL082ARZ-REEL7 offers the highest inventory availability at 22,215 pieces, followed by ADTL082ARMZ at 18,573 pieces.
Frequently Asked Questions (FAQ)
Q: Can the AD826ANZ be used as a direct replacement for the TLE2022MDR?
A: The AD826ANZ is functionally compatible as a dual-circuit operational amplifier but is not a direct pin-compatible replacement. The AD826ANZ uses an 8-DIP through-hole package (0.300", 7.62mm), while the TLE2022MDR uses an 8-SOIC surface mount package (0.154", 3.90mm Width). PCB layout and mounting technology modifications are required. For direct surface mount replacement, use AD826ARZ, AD826ARZ-REEL, or AD826ARZ-REEL7.
Q: What is the difference between AD826ARZ, AD826ARZ-REEL, and AD826ARZ-REEL7?
A: These three part numbers represent the same device with different packaging and delivery formats. AD826ARZ is supplied in tube packaging. AD826ARZ-REEL and AD826ARZ-REEL7 are supplied on cut tape with Digi-Reel® format. The electrical specifications and 8-SOIC package are identical across all three variants. Selection depends on manufacturing process requirements and inventory management preferences.
Q: Are the ADTL082 series devices suitable for low-power applications?
A: The ADTL082 series devices consume 1.2 mA total supply current (x2 channels), which is lower than the TLE2022MDR at 550 µA per channel (1.1 mA total). However, the ADTL082 series requires a minimum supply voltage of 8V, compared to 4V for the TLE2022MDR. For applications with supply voltages below 8V, the ADTL082 series is not suitable.
Q: What are the key performance differences between the TLE2022MDR and ISL28227FBZ?
A: The ISL28227FBZ provides superior input offset voltage performance (10 µV versus 150 µV) and higher gain bandwidth product (10 MHz versus 2.8 MHz). The ISL28227FBZ also features lower input bias current (1 nA versus 35 nA). Both devices support the same operating temperature range (-40°C to 125°C) and are available in 8-SOIC surface mount packages. The ISL28227FBZ carries MSL rating of 2 (1 Year), requiring controlled moisture handling.
Q: Can the ADTL082ARMZ be used in place of the TLE2022MDR in a -55°C application?
A: No. The ADTL082ARMZ operates from -40°C to 125°C and does not support the extended low-temperature range of -55°C provided by the TLE2022MDR. For applications requiring operation at -55°C, the TLE2022MDR must be used.
Q: What is the impact of higher slew rate in the AD826 series?
A: The AD826 series provides a slew rate of 350 V/µs compared to 0.65 V/µs in the TLE2022MDR. Higher slew rate enables faster signal transitions and is beneficial for high-frequency applications. However, the AD826 series also exhibits higher input bias current (3.3 µA versus 35 nA) and higher input offset voltage (500 µV versus 150 µV), which may impact precision analog applications.
Q: Are all substitute parts available in tape and reel packaging?
A: The AD826 series is available in tube and cut tape with Digi-Reel® formats. The ADTL082 series is available in tube and cut tape with Digi-Reel® formats. The ISL28227FBZ is available in tube packaging. For automated assembly processes requiring tape and reel delivery, AD826ARZ-REEL, AD826ARZ-REEL7, ADTL082ARMZ-REEL, ADTL082ARZ-REEL, and ADTL082ARZ-REEL7 are suitable options.
Q: What is the significance of the MSL rating difference between TLE2022MDR and ISL28227FBZ?
A: The TLE2022MDR carries MSL rating of 1 (Unlimited), indicating unlimited shelf life under controlled storage conditions. The ISL28227FBZ carries MSL rating of 2 (1 Year), requiring that the device be used within one year of the manufacturing date if exposed to moisture. For applications with extended inventory holding periods, the TLE2022MDR or other MSL 1 rated devices are preferred.
Q: Which substitute part provides the best match for general purpose amplifier applications?
A: The ISL28227FBZ maintains the general purpose amplifier classification and provides improved specifications including lower input offset voltage (10 µV), lower input bias current (1 nA), and higher gain bandwidth product (10 MHz). The ISL28227FBZ is available in 8-SOIC surface mount package with compatible supply voltage range (4.5V to 40V) and extended operating temperature support (-40°C to 125°C). The primary consideration is the MSL rating of 2 (1 Year), which requires controlled moisture handling.
