Engineering Selection Recommendations

TLC2202IP (Primary Recommendation)

The TLC2202IP is the direct functional equivalent of the TLC2202IPG4. Both devices share identical electrical specifications including slew rate (2.7V/µs), gain bandwidth product (1.9 MHz), input bias current (4 µA), and output current capability (50 mA per channel). The TLC2202IP maintains the same operating temperature range (-40°C to 85°C) and supply voltage span (4.6V to 16V). This part is currently in Active product status with 1204 units in stock, providing immediate availability. Both parts are ROHS3 compliant and manufactured by Texas Instruments. The TLC2202IP is the optimal choice for direct replacement in existing designs without circuit modification.

LMC662AIN/NOPB (Secondary Recommendation)

The LMC662AIN/NOPB is a functionally compatible substitute manufactured by National Semiconductor. This device maintains the dual-channel CMOS architecture in an 8-DIP package with rail-to-rail output capability. The LMC662AIN/NOPB offers superior input bias current performance (0.000002 µA versus 4 µA) and lower supply current consumption (0.75 mA versus 5.6 mA across both channels), making it advantageous for low-power applications. However, the slew rate (1.1V/µs) and gain bandwidth product (1.4 MHz) are reduced compared to the TLC2202IPG4. The operating temperature range (-40°C to 85°C) is identical. This part is currently Active with 3225 units in stock. Selection of this substitute requires verification that reduced slew rate and bandwidth do not impact circuit performance.

LMC662CN/NOPB (Tertiary Recommendation)

The LMC662CN/NOPB is a Texas Instruments-manufactured variant of the LMC662 series with identical electrical specifications to the LMC662AIN/NOPB. This part is in Last Time Buy status, indicating limited future availability. The operating temperature range is restricted to 0°C to 70°C, which does not support the full -40°C to 85°C specification of the TLC2202IPG4. Selection of this part is appropriate only for applications operating within the 0°C to 70°C temperature window. The LMC662CN/NOPB is supplied in Tube packaging with 1836 units currently in stock.

Frequently Asked Questions (FAQ)

Q: Can the TLC2202IP be used as a direct replacement for the TLC2202IPG4?

A: Yes. The TLC2202IP is electrically and mechanically identical to the TLC2202IPG4. Both devices feature the same CMOS dual-channel architecture, 8-DIP through-hole package, slew rate (2.7V/µs), gain bandwidth product (1.9 MHz), supply voltage range (4.6V to 16V), and operating temperature range (-40°C to 85°C). No circuit modifications are required.

Q: What are the key differences between the TLC2202IPG4 and LMC662AIN/NOPB?

A: The primary differences are slew rate and supply current consumption. The TLC2202IPG4 provides 2.7V/µs slew rate and 5.6 mA total supply current, while the LMC662AIN/NOPB provides 1.1V/µs slew rate and 0.75 mA total supply current. The LMC662AIN/NOPB also features significantly lower input bias current (0.000002 µA versus 4 µA). Both devices maintain identical package form factor, dual-channel configuration, and rail-to-rail output capability. The reduced slew rate and bandwidth of the LMC662AIN/NOPB may limit performance in high-frequency applications.

Q: Why is the LMC662CN/NOPB not recommended as a primary substitute?

A: The LMC662CN/NOPB is in Last Time Buy status, indicating discontinued production and limited inventory availability. Additionally, the operating temperature range is restricted to 0°C to 70°C, which does not support the full -40°C to 85°C specification of the TLC2202IPG4. This part is suitable only for applications with restricted temperature requirements and where long-term availability is not a concern.

Q: Are all substitute parts available in the same 8-DIP through-hole package?

A: Yes. All substitute parts listed (TLC2202IP, LMC662AIN/NOPB, and LMC662CN/NOPB) are packaged in 8-DIP (0.300", 7.62mm) through-hole configuration, ensuring mechanical compatibility with existing printed circuit board layouts and socket configurations.

Q: What compliance certifications apply to these substitute parts?

A: The TLC2202IP and LMC662CN/NOPB are ROHS3 compliant. All parts are classified under ECCN EAR99 and HTSUS 8542.33.0001. The LMC662AIN/NOPB compliance status is not specified in the provided data. Verification of specific compliance requirements for your application is recommended.

Q: Can the LMC662 series be used in applications requiring the full -40°C to 85°C temperature range?

A: The LMC662AIN/NOPB supports the full -40°C to 85°C operating temperature range. The LMC662CN/NOPB is restricted to 0°C to 70°C and is not suitable for applications requiring extended low-temperature operation below 0°C or high-temperature operation above 70°C.
