TLE2022ACDRG4 Equivalent & Substitute Parts

Part Overview

The TLE2022ACDRG4 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 designed for applications requiring low-power, dual-channel amplification with moderate bandwidth and slew rate characteristics.

The TLE2022ACDRG4 is currently discontinued at DiGi Electronics. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements. Substitute parts must maintain electrical compatibility across critical parameters including supply voltage range, output current capability, input bias current, and package form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLE2022ACDRG4 are identified based on strict electrical and mechanical compatibility criteria. The following parameters define acceptable substitution:

Primary Compatibility Criteria:

• Dual-circuit general purpose operational amplifier configuration
• 8-SOIC surface mount package (0.154", 3.90mm Width)
• Supply voltage range compatibility: minimum 4 V to 4.5 V, maximum 40 V
• Output current capability: minimum 30 mA per channel
• Input bias current within acceptable range for general purpose applications
• RoHS3 compliance and EAR99 classification

Identified Substitute Parts:

1. TLE2022ACDR (Texas Instruments) — Direct manufacturer variant with identical electrical specifications and active product status
2. ISL28227FBZ (Renesas Electronics Corporation) — Alternative manufacturer solution with enhanced performance characteristics and extended operating temperature range

Both substitute parts maintain the 8-SOIC package form factor and satisfy the core electrical requirements for functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

TLE2022ACDR Selection Criteria:

The TLE2022ACDR is the manufacturer-recommended direct substitute for the discontinued TLE2022ACDRG4. Both parts are manufactured by Texas Instruments and share identical electrical specifications across all measured parameters. The TLE2022ACDR maintains active product status with 16,204 units in stock, ensuring supply chain continuity. This part is supplied in Cut Tape (CT) and Digi-Reel® packaging formats. Selection of the TLE2022ACDR is appropriate for applications where electrical performance characteristics and operating temperature range (0°C to 70°C) match the original design requirements. RoHS3 compliance and MSL 1 rating are maintained.

ISL28227FBZ Selection Criteria:

The ISL28227FBZ, manufactured by Renesas Electronics Corporation, is an alternative substitute offering enhanced performance characteristics. This part provides superior slew rate (3.6 V/µs versus 0.65 V/µs), higher gain bandwidth product (10 MHz versus 2.8 MHz), lower input bias current (1 nA versus 33 nA), and lower input offset voltage (10 µV versus 120 µV). The ISL28227FBZ supports an extended operating temperature range (-40°C to 125°C) compared to the original part. Output current capability is increased to 45 mA per channel. Supply current consumption is significantly reduced to 2.2 mA across both channels. The minimum supply voltage is 4.5 V, which is 0.5 V higher than the original specification. Selection of the ISL28227FBZ is appropriate for applications requiring improved dynamic performance, lower power consumption, or extended temperature operation. RoHS3 compliance is maintained; however, MSL rating is 2 (1 Year) versus MSL 1 for the original part. The ISL28227FBZ is supplied in Tube packaging with 9,880 units in stock.

Both substitute parts maintain the 8-SOIC package form factor, ensuring mechanical compatibility with existing PCB layouts and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the TLE2022ACDR be used as a direct replacement for the TLE2022ACDRG4?

A: Yes. The TLE2022ACDR is the manufacturer-recommended substitute. Both parts share identical electrical specifications, including slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current, and supply voltage range. The primary difference is product status: TLE2022ACDR is active with available inventory, while TLE2022ACDRG4 is discontinued. Packaging format differs (Cut Tape/Digi-Reel versus the original packaging), but the 8-SOIC package dimensions are identical.

Q: What are the key differences between TLE2022ACDR and ISL28227FBZ?

A: The ISL28227FBZ offers enhanced performance across multiple parameters: slew rate is 5.5 times faster (3.6 V/µs), gain bandwidth product is 3.6 times higher (10 MHz), input bias current is 33 times lower (1 nA), and input offset voltage is 12 times lower (10 µV). Supply current consumption is reduced by 75% (2.2 mA). Output current per channel is increased by 50% (45 mA). Operating temperature range is extended from 0–70°C to -40–125°C. The minimum supply voltage is 0.5 V higher (4.5 V). MSL rating differs: ISL28227FBZ is MSL 2 (1 Year) versus MSL 1 (Unlimited) for the original part.

Q: Are both substitute parts RoHS3 compliant?

A: Yes. Both TLE2022ACDR and ISL28227FBZ are RoHS3 compliant, matching the compliance status of the original TLE2022ACDRG4.

Q: What is the impact of the ISL28227FBZ's higher minimum supply voltage (4.5 V versus 4 V)?

A: The ISL28227FBZ requires a minimum supply voltage of 4.5 V, which is 0.5 V higher than the TLE2022ACDRG4 specification of 4 V. Applications operating at supply voltages between 4.0 V and 4.4 V cannot use the ISL28227FBZ. Designs with supply voltages at or above 4.5 V are unaffected by this difference.

Q: Does the ISL28227FBZ's MSL 2 rating affect component handling?

A: The ISL28227FBZ has an MSL rating of 2 (1 Year), compared to MSL 1 (Unlimited) for the original part. MSL 2 indicates the component must be used within one year of the manufacturing date if exposed to moisture. This requires adherence to moisture control procedures during storage and handling. The original part, with MSL 1 rating, has no time-based moisture sensitivity restrictions.

Q: Can the ISL28227FBZ be used in applications requiring the original 0°C to 70°C operating temperature range?

A: Yes. The ISL28227FBZ supports an extended operating temperature range of -40°C to 125°C, which encompasses the original 0°C to 70°C specification. Applications limited to 0–70°C operation are fully compatible with the ISL28227FBZ.

Q: Are the 8-SOIC packages for all three parts mechanically identical?

A: Yes. All three parts use the 8-SOIC package with identical dimensions: 0.154 inches (3.90 mm) width. PCB footprints and assembly processes are mechanically compatible across all three parts.

Q: Which substitute part should be selected for new designs?

A: Selection depends on application requirements. For designs matching the original electrical specifications and operating temperature range, the TLE2022ACDR is the appropriate choice due to its active status and identical performance. For applications benefiting from enhanced performance, lower power consumption, or extended temperature operation, the ISL28227FBZ is suitable, provided the 4.5 V minimum supply voltage and MSL 2 handling requirements are acceptable.
