TLC27L7IP Equivalent & Substitute Parts

Part Overview

The TLC27L7IP is a CMOS amplifier integrated circuit containing two independent circuits in an 8-pin DIP package. Manufactured by Texas Instruments under the LinCMOS™ series, this component is classified as a Last Time Buy product, indicating discontinued production with limited remaining inventory. The TLC27L7IP 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 becomes necessary when the TLC27L7IP reaches end-of-life status or when alternative packaging formats are required for manufacturing processes. Substitute components must maintain electrical compatibility across critical parameters including supply voltage range, input bias current, output current capability, and operating temperature specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC27L7IP is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Amplifier Type: CMOS technology
• Number of Circuits: 2 independent circuits
• Voltage Supply Range: Minimum 4V, Maximum 16V
• Input Bias Current: 0.6 pA maximum
• Slew Rate: 0.03 V/µs
• Gain Bandwidth Product: 110 kHz
• Operating Temperature Range: -40°C to 85°C
• Output Current per Channel: 30 mA minimum

Packaging Considerations:

• Through-hole mounting compatibility (8-DIP package format)
• Pin configuration alignment with 8-pin DIP standard

The TLC27L7IDR represents a direct electrical equivalent with identical performance specifications but differs in packaging format (8-SOIC surface mount versus 8-DIP through hole). This substitute is applicable only in designs where surface-mount assembly is employed.

The NJM13404D# is a general-purpose amplifier that shares the same package format (8-DIP through hole) and operating temperature range but exhibits different electrical characteristics. This component operates with a lower minimum supply voltage (2V versus 4V), higher slew rate (1.2 V/µs versus 0.03 V/µs), and significantly higher gain bandwidth product (2 MHz versus 110 kHz). The NJM13404D# is suitable only for applications where the TLC27L7IP's specific low-speed, low-power characteristics are not required.

Engineering Selection Recommendations

TLC27L7IDR Selection: The TLC27L7IDR is the manufacturer-recommended direct substitute for the TLC27L7IP when surface-mount assembly is required. This component maintains identical electrical specifications across all critical parameters: slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, and output current capability. Both components operate across the same supply voltage range (4V to 16V) and temperature range (-40°C to 85°C). The TLC27L7IDR carries Active product status with ROHS3 compliance, ensuring long-term availability and regulatory compliance. Selection of the TLC27L7IDR is appropriate for new designs or manufacturing transitions from through-hole to surface-mount technology.

NJM13404D# Selection: The NJM13404D# is suitable only for applications where the specific performance characteristics of the TLC27L7IP are not required. This component exhibits significantly different electrical behavior: 40× higher slew rate, 18× higher gain bandwidth product, and 100× higher input bias current. The NJM13404D# operates at lower minimum supply voltage (2V) but with substantially higher supply current consumption (2mA versus 20µA). Selection of the NJM13404D# is restricted to legacy designs or applications requiring higher-speed amplification. The component maintains through-hole 8-DIP packaging compatibility and RoHS compliance but introduces electrical performance deviations that may affect circuit behavior.

Product Status Consideration: The TLC27L7IP is designated Last Time Buy, indicating production discontinuation. For new designs or long-term production requirements, the TLC27L7IDR (Active status) is the appropriate selection. Existing through-hole designs may continue using remaining TLC27L7IP inventory with transition planning to the TLC27L7IDR for future manufacturing phases.

Frequently Asked Questions (FAQ)

Q: Can the TLC27L7IDR directly replace the TLC27L7IP in existing through-hole PCB designs?

A: No. The TLC27L7IDR uses 8-SOIC surface-mount packaging (0.154" width) while the TLC27L7IP uses 8-DIP through-hole packaging (0.300" width). PCB layout and footprint modifications are required. For through-hole designs, the TLC27L7IP remains the appropriate component until design migration to surface-mount assembly is planned.

Q: What are the key electrical differences between the TLC27L7IP and NJM13404D#?

A: The NJM13404D# operates with 40× faster slew rate (1.2 V/µs versus 0.03 V/µs), 18× higher gain bandwidth product (2 MHz versus 110 kHz), and 100× higher input bias current (25 nA versus 0.6 pA). Supply current consumption is 100× higher (2 mA versus 20 µA). These differences make the NJM13404D# unsuitable for low-power, low-frequency applications designed around the TLC27L7IP specifications.

Q: Are both substitute parts RoHS compliant?

A: Yes. The TLC27L7IDR is ROHS3 compliant. The NJM13404D# is RoHS compliant. Both components meet regulatory requirements for hazardous substance restrictions.

Q: What is the minimum supply voltage for each component?

A: The TLC27L7IP and TLC27L7IDR require minimum 4V supply voltage. The NJM13404D# operates at lower minimum supply voltage of 2V, allowing use in battery-powered applications with lower voltage rails.

Q: Can the NJM13404D# be used in a circuit designed for the TLC27L7IP?

A: Electrical substitution is not recommended without circuit redesign. The NJM13404D# exhibits fundamentally different performance characteristics: significantly higher slew rate, gain bandwidth product, and input bias current. These differences will alter circuit behavior, frequency response, and noise characteristics. Use of the NJM13404D# requires complete circuit analysis and potential redesign of feedback networks and compensation components.

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

A: The TLC27L7IDR is the manufacturer-recommended substitute for new designs. This component maintains identical electrical specifications to the TLC27L7IP while offering Active product status and long-term availability. Surface-mount assembly is standard in modern manufacturing processes.

Q: What is the inventory status of each component?

A: The TLC27L7IP has 4211 pieces in stock (Last Time Buy status). The TLC27L7IDR has 2257 pieces in stock (Active status). The NJM13404D# has 776 pieces in stock (Active status). For long-term supply assurance, the TLC27L7IDR is preferred due to Active product status.
