Substitute Part Grouping Explanation

Substitution of the TLC2272ACDRG4 is determined by the following critical parameters:

Primary Substitution Criteria:

Package type: 8-SOIC surface mount form factor
Amplifier configuration: Dual-channel (2 circuits)
Output architecture: Rail-to-rail capability
Amplifier topology: CMOS technology
Supply voltage range compatibility: Minimum 4.4 V to maximum 16 V
Operating temperature range: 0°C to 70°C or wider
Compliance: RoHS3 and REACH requirements

Substitute parts are grouped into two categories:

Category 1 - Direct TLC2272 Series Substitutes: The TLC2272ACDR represents the active production equivalent of the TLC2272ACDRG4. Both parts share identical electrical specifications and differ only in packaging format (Cut Tape & Digi-Reel versus standard packaging). This part maintains full compatibility with the original design.

Category 2 - LMC6082 Series Substitutes: The LMC6082AIMX/NOPB, LMC6082AIM/NOPB, LMC6082IMX/NOPB, and LMC6082IM/NOPB represent alternative CMOS dual-channel amplifiers in 8-SOIC packaging. These parts share the same package footprint and dual-channel configuration. However, they feature different electrical performance characteristics, including lower slew rate (1.5 V/µs versus 3.6 V/µs), lower gain bandwidth product (1.3 MHz versus 2.25 MHz), and extended operating temperature range (-40°C to 85°C). The LMC6082 series offers push-pull output architecture compared to the standard rail-to-rail output of the TLC2272.

Category 3 - Cross-Manufacturer Substitute: The MC33202DR2G from onsemi is a general-purpose dual-channel amplifier in 8-SOIC packaging with rail-to-rail output. This part operates across a wider supply voltage range (1.8 V to 12 V) and extended temperature range (-40°C to 105°C). However, it exhibits significantly different electrical characteristics, including higher input bias current (80 nA versus 1 pA), higher input offset voltage (8 mV versus 300 µV), lower slew rate (1 V/µs), and lower supply current (900 µA versus 2.4 mA per channel).

Engineering Selection Recommendations

Primary Recommendation: TLC2272ACDR

The TLC2272ACDR is the recommended substitute for the obsolete TLC2272ACDRG4. This part maintains identical electrical specifications and performance characteristics while carrying Active product status. The TLC2272ACDR is available in Cut Tape and Digi-Reel packaging formats, ensuring compatibility with automated assembly processes. Both parts are RoHS3 compliant and carry MSL Level 1 rating. Selection of the TLC2272ACDR eliminates design modification requirements and preserves all original circuit performance parameters.

Secondary Recommendation: LMC6082AIMX/NOPB or LMC6082IMX/NOPB

The LMC6082 series substitutes are suitable when extended operating temperature range (-40°C to 85°C) is required beyond the original 0°C to 70°C specification. These parts maintain the same 8-SOIC package footprint and dual-channel configuration. However, circuit performance will be affected by reduced slew rate (1.5 V/µs versus 3.6 V/µs) and lower gain bandwidth product (1.3 MHz versus 2.25 MHz). The LMC6082AIMX/NOPB carries Active status with Cut Tape packaging, while LMC6082IMX/NOPB also maintains Active status. Both are RoHS3 compliant. Design verification is required to confirm that reduced slew rate and bandwidth do not compromise application performance.

Tertiary Recommendation: MC33202DR2G

The MC33202DR2G from onsemi represents a cross-manufacturer alternative with Active product status and extended operating temperature range (-40°C to 105°C). This part is suitable only for applications where the significantly different electrical characteristics are acceptable. The MC33202DR2G exhibits substantially higher input bias current (80 nA versus 1 pA) and input offset voltage (8 mV versus 300 µV), which may introduce unacceptable errors in precision analog circuits. The lower supply current (900 µA per channel) may provide power consumption benefits in battery-powered applications. RoHS3 compliance and MSL Level 1 rating are maintained. Comprehensive circuit simulation and prototype testing are required before design implementation.

Frequently Asked Questions (FAQ)

Q1: Can I directly replace TLC2272ACDRG4 with TLC2272ACDR without circuit modification?

A: Yes. The TLC2272ACDR is electrically and functionally identical to the TLC2272ACDRG4. Both parts share the same 8-SOIC package footprint, identical pin configuration, and identical electrical specifications. The only difference is packaging format. No circuit modification, PCB redesign, or firmware changes are required. Direct substitution is supported.

Q2: What are the key differences between TLC2272ACDR and LMC6082AIMX/NOPB?

A: Both parts are dual-channel CMOS amplifiers in 8-SOIC packaging with rail-to-rail output capability. However, they differ significantly in performance: TLC2272ACDR provides 3.6 V/µs slew rate and 2.25 MHz gain bandwidth product, while LMC6082AIMX/NOPB provides 1.5 V/µs slew rate and 1.3 MHz gain bandwidth product. The LMC6082 offers lower supply current (1.1 mA per channel versus 2.4 mA) and extended operating temperature range (-40°C to 85°C versus 0°C to 70°C). Selection depends on whether your application requires higher speed performance or lower power consumption with extended temperature operation.

Q3: Is the MC33202DR2G a suitable replacement for high-precision analog applications?

A: The MC33202DR2G is not recommended for high-precision applications. This part exhibits input offset voltage of 8 mV compared to 300 µV for the TLC2272ACDRG4—a 26-fold increase. Input bias current is 80 nA versus 1 pA, representing an 80,000-fold increase. These characteristics make the MC33202DR2G unsuitable for precision instrumentation, sensor signal conditioning, or applications requiring low-noise, low-offset performance. The MC33202DR2G is appropriate only for general-purpose applications where offset and bias current specifications are non-critical.

Q4: Can I use LMC6082 series parts in applications requiring 0°C to 70°C operation?

A: Yes. The LMC6082 series parts are rated for -40°C to 85°C operation, which encompasses the 0°C to 70°C range. However, you must verify that the reduced electrical performance (lower slew rate and bandwidth) does not compromise your application requirements. The LMC6082 series is suitable for applications where extended temperature capability is beneficial but not required.

Q5: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed—TLC2272ACDR, LMC6082AIMX/NOPB, LMC6082AIM/NOPB, LMC6082IMX/NOPB, LMC6082IM/NOPB, and MC33202DR2G—carry RoHS3 compliance certification. All parts also maintain MSL Level 1 (Unlimited) moisture sensitivity rating. Compliance with environmental and regulatory requirements is maintained across all substitutes.

Q6: What packaging formats are available for substitute parts?

A: The TLC2272ACDR is available in Cut Tape and Digi-Reel packaging. The LMC6082AIMX/NOPB and LMC6082IMX/NOPB are supplied in Cut Tape and Digi-Reel format. The LMC6082AIM/NOPB and LMC6082IM/NOPB are supplied in Tube packaging. The MC33202DR2G is available in Cut Tape and Digi-Reel format. Verify packaging compatibility with your assembly process requirements before procurement.

Q7: Which substitute part offers the lowest power consumption?

A: The MC33202DR2G provides the lowest supply current at 900 µA per channel (dual channel total 1.8 mA), compared to 2.4 mA per channel for TLC2272ACDR and 1.1 mA per channel for LMC6082 series. However, power consumption reduction must be weighed against the significantly degraded precision specifications of the MC33202DR2G. The LMC6082 series offers a balanced compromise with 1.1 mA per channel supply current and acceptable precision for general-purpose applications.

Q8: What is the supply voltage compatibility range for each substitute?

A: TLC2272ACDR operates from 4.4 V to 16 V. LMC6082 series parts operate from 4.5 V to 15.5 V. MC33202DR2G operates from 1.8 V to 12 V. If your application requires operation below 4.4 V or above 15.5 V, only the MC33202DR2G supports the extended lower voltage range. However, the MC33202DR2G maximum supply voltage (12 V) is lower than the TLC2272 series maximum (16 V).
