TLC272IPG4 Equivalent & Substitute Parts

Part Overview

The TLC272IPG4 is a CMOS dual-channel operational amplifier manufactured by Texas Instruments, housed in an 8-DIP through-hole package. This device is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The TLC272IPG4 operates across a wide supply voltage range of 4V to 16V and is suitable for applications requiring low input bias current and moderate bandwidth performance in CMOS technology.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC272IPG4 is determined by strict alignment of electrical and mechanical parameters within the CMOS amplifier category. The following criteria establish valid substitution relationships:

Primary Substitution Criteria:

• Dual-channel (2 circuits) operational amplifier architecture
• 8-DIP through-hole package format (0.300", 7.62mm)
• CMOS amplifier technology
• Supply voltage range compatibility: minimum 4V, maximum 16V
• Operating temperature range: -40°C to 85°C
• Slew rate: 5.3 V/µs or equivalent
• Gain bandwidth product: 2.2 MHz or equivalent
• Input bias current: 0.7 pA or lower
• Output current capability: 30 mA per channel or greater

Substitution Logic: The TLC272IP (active product status) is a direct equivalent of the TLC272IPG4, differing only in packaging format (tube versus tray) and product status. All electrical and mechanical specifications are identical.

The NJM13404D# represents a functional alternative within the general-purpose amplifier category. While it maintains the same package format and dual-channel configuration, it operates as a general-purpose amplifier rather than CMOS technology. Electrical parameters differ in specific areas: slew rate (1.2 V/µs versus 5.3 V/µs), input bias current (25 nA versus 0.7 pA), and supply current (2 mA versus 1.4 mA). The supply voltage range is narrower (2V to 14V versus 4V to 16V). This part is suitable only when application requirements permit these parameter variations.

Parameter Comparison

Engineering Selection Recommendations

TLC272IP (Recommended Primary Substitute): The TLC272IP is the direct active-production equivalent of the TLC272IPG4. All electrical specifications, package format, and operating parameters are identical. The only difference is product status (active versus obsolete) and packaging format (tube versus tray). This part is ROHS3 compliant and maintains full compatibility with existing designs. Selection of TLC272IP requires no circuit redesign or performance re-evaluation.

NJM13404D# (Alternative Substitute): The NJM13404D# is suitable as a substitute only when application requirements accommodate the specified parameter differences. This part operates as a general-purpose amplifier rather than CMOS technology, resulting in higher input bias current (25 nA versus 0.7 pA), lower slew rate (1.2 V/µs versus 5.3 V/µs), and narrower supply voltage range (2V to 14V versus 4V to 16V). The NJM13404D# is RoHS compliant and maintains the same 8-DIP through-hole package format. Circuit redesign and performance verification are required before implementation.

Frequently Asked Questions (FAQ)

Q: Can TLC272IP be used as a direct replacement for TLC272IPG4? A: Yes. The TLC272IP is electrically and mechanically identical to the TLC272IPG4. The only differences are product status (active versus obsolete) and packaging format (tube versus tray). No circuit modifications are required.

Q: What are the key differences between TLC272IPG4 and NJM13404D#? A: The primary differences are amplifier technology (CMOS versus general-purpose), slew rate (5.3 V/µs versus 1.2 V/µs), input bias current (0.7 pA versus 25 nA), and supply voltage range (4V-16V versus 2V-14V). The NJM13404D# is suitable only when application specifications permit these variations.

Q: Are all substitute parts available in the same 8-DIP package? A: Yes. Both TLC272IP and NJM13404D# are available in 8-DIP (0.300", 7.62mm) through-hole packages, maintaining identical PCB footprints with the TLC272IPG4.

Q: What is the significance of the obsolete status of TLC272IPG4? A: Obsolete status indicates that Texas Instruments has discontinued production of this specific part number. The TLC272IP (active status) provides continued availability and supply chain support for the same functionality.

Q: Are there compliance or certification differences between the substitute parts? A: TLC272IP is ROHS3 compliant, matching the TLC272IPG4. NJM13404D# is RoHS compliant. Both parts are REACH unaffected and carry EAR99 ECCN classification. Moisture sensitivity level (MSL) is 1 (Unlimited) for both TLC272IPG4 and NJM13404D#.

Q: Can NJM13404D# be used in high-speed applications requiring 5.3 V/µs slew rate? A: No. The NJM13404D# has a maximum slew rate of 1.2 V/µs, which is insufficient for applications requiring the 5.3 V/µs performance of the TLC272IPG4. Use TLC272IP for such applications.

Q: What is the input bias current difference, and does it matter? A: The TLC272IPG4 and TLC272IP have 0.7 pA input bias current, while NJM13404D# has 25 nA. This 35,000-fold difference is significant in high-impedance input circuits. Applications with impedances above 1 MΩ should use TLC272IP to minimize input bias current errors.
