TLC27L2AIP Equivalent & Substitute Parts

Part Overview

The TLC27L2AIP is a CMOS amplifier integrated circuit containing two independent circuits in an 8-pin DIP package. This device is classified as a Last Time Buy product, indicating discontinued production with limited remaining inventory. The TLC27L2AIP operates across a wide supply voltage range of 4V to 16V and is designed for low-power applications requiring minimal input bias current and low supply current consumption. Identification of equivalent and substitute parts is necessary due to the Last Time Buy status and to support design flexibility across different packaging and manufacturing requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC27L2AIP is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Amplifier Type: CMOS technology
• Number of Circuits: 2 independent circuits
• Slew Rate: 0.03 V/µs
• Gain Bandwidth Product: 110 kHz
• Current - Input Bias: 0.6 pA
• Voltage - Input Offset: 900 µV
• Current - Supply: 20 µA (x2 Channels)
• Current - Output / Channel: 30 mA
• Voltage - Supply Span: 4V to 16V
• Operating Temperature Range: -40°C to 85°C

Mechanical Compatibility Criteria:

• Package configuration and pin count
• Mounting type (Through Hole vs. Surface Mount)
• Physical dimensions and footprint

Substitute parts are grouped into two categories:

1. Identical Electrical Specifications with Different Packaging: TLC27L2AIDR maintains all electrical parameters but uses surface-mount 8-SOIC packaging instead of through-hole 8-DIP.

2. Different Amplifier Type with Same Package: NJM13404D# uses the same through-hole 8-DIP package but operates as a General Purpose amplifier with different electrical specifications, including higher slew rate (1.2 V/µs), higher gain bandwidth product (2 MHz), and different bias current characteristics.

Engineering Selection Recommendations

TLC27L2AIDR Selection: The TLC27L2AIDR is the manufacturer-recommended substitute for the TLC27L2AIP when design requirements permit surface-mount assembly. This part maintains identical electrical specifications including slew rate, gain bandwidth product, input bias current, and supply voltage range. Both devices are ROHS3 compliant and carry Active product status, ensuring long-term availability. The TLC27L2AIDR is suitable for applications transitioning from through-hole to surface-mount manufacturing processes while maintaining circuit performance without modification.

NJM13404D# Selection: The NJM13404D# is a through-hole alternative that preserves the 8-DIP package footprint of the TLC27L2AIP. However, this substitute operates as a General Purpose amplifier with significantly different electrical characteristics. The NJM13404D# exhibits higher slew rate (1.2 V/µs vs. 0.03 V/µs), higher gain bandwidth product (2 MHz vs. 110 kHz), and substantially higher input bias current (25 nA vs. 0.6 pA). The NJM13404D# is suitable only for applications where the TLC27L2AIP's low-power CMOS characteristics are not required and where the higher performance metrics of a general-purpose amplifier are acceptable. The minimum supply voltage for NJM13404D# is 2V, providing greater flexibility in low-voltage applications.

Product Status Consideration: The TLC27L2AIP carries Last Time Buy status with limited inventory (2020 pcs). The TLC27L2AIDR is the preferred long-term substitute, offering Active product status and significantly higher inventory availability (30400 pcs). For new designs or production requiring extended component availability, TLC27L2AIDR is the recommended selection.

Frequently Asked Questions (FAQ)

Q: Can TLC27L2AIDR be used as a direct replacement for TLC27L2AIP in existing through-hole PCB designs?

A: No. The TLC27L2AIDR uses 8-SOIC surface-mount packaging, while the TLC27L2AIP uses 8-DIP through-hole packaging. PCB layout and assembly process modifications are required. However, electrical performance is identical, and circuit functionality remains unchanged with appropriate adapter solutions or PCB redesign.

Q: What are the key electrical differences between TLC27L2AIP and NJM13404D#?

A: The primary differences are amplifier classification and performance metrics. TLC27L2AIP is a CMOS amplifier optimized for low-power applications with 0.03 V/µs slew rate and 110 kHz bandwidth. NJM13404D# is a general-purpose amplifier with 1.2 V/µs slew rate and 2 MHz bandwidth. Input bias current differs significantly: 0.6 pA for TLC27L2AIP versus 25 nA for NJM13404D#. Supply current consumption is 20 µA for TLC27L2AIP versus 2 mA for NJM13404D#.

Q: Are both substitute parts RoHS compliant?

A: Yes. TLC27L2AIDR is ROHS3 compliant. NJM13404D# is RoHS compliant. Both meet environmental compliance requirements for restricted substance use.

Q: Which substitute part should be selected for a new design?

A: TLC27L2AIDR is the manufacturer-recommended substitute and carries Active product status with high inventory availability. This part is suitable for new designs requiring identical electrical performance to the TLC27L2AIP. NJM13404D# should be selected only when higher slew rate and bandwidth performance are required and when the increased supply current consumption is acceptable.

Q: What is the impact of supply voltage range differences between TLC27L2AIP and NJM13404D#?

A: TLC27L2AIP operates from 4V to 16V. NJM13404D# operates from 2V to 14V. Applications requiring operation below 4V supply voltage can use NJM13404D#. Applications requiring operation above 14V supply voltage must use TLC27L2AIP or TLC27L2AIDR.

Q: Can NJM13404D# be used in low-power battery-operated applications designed for TLC27L2AIP?

A: NJM13404D# is not suitable for low-power battery applications. Supply current consumption is 2 mA compared to 20 µA for TLC27L2AIP, representing a 100-fold increase in power consumption. This difference significantly impacts battery life and thermal performance in portable applications.

Q: What packaging considerations apply when selecting between these parts?

A: TLC27L2AIP and NJM13404D# both use 8-DIP through-hole packaging with identical 0.300" (7.62mm) spacing, allowing direct socket compatibility. TLC27L2AIDR uses 8-SOIC surface-mount packaging (0.154", 3.90mm width) and requires different PCB footprint and assembly process. Package selection depends on manufacturing capability and PCB design requirements.
