TL054IN Equivalent & Substitute Parts

Part Overview

The TL054IN is a J-FET input operational amplifier manufactured by Texas Instruments, featuring four independent amplifier circuits in a 14-pin DIP package. This device is classified as a Last Time Buy product, indicating discontinued production with limited inventory availability. The TL054IN operates across a wide supply voltage range of 10V to 30V and is suitable for applications requiring low input bias current and stable gain-bandwidth characteristics. Due to its Last Time Buy status, identifying equivalent substitute parts with compatible electrical and mechanical specifications is essential for design continuity and long-term component sourcing.

Substitute Part Grouping Explanation

Substitution of the TL054IN is determined by strict equivalence across all critical electrical parameters and compliance certifications. The substitute part must maintain identical specifications for amplifier type (J-FET), circuit count (4), slew rate (17.8 V/µs), gain bandwidth product (2.7 MHz), input bias current (30 pA), input offset voltage (560 µV), supply current (8.4 mA across four channels), output current per channel (80 mA), and supply voltage range (10V to 30V minimum, 30V maximum). Operating temperature range (-40°C to 85°C) and RoHS3 compliance are mandatory matching criteria. The primary difference between the main part and its substitute lies in the mounting technology and package form factor: the TL054IN utilizes through-hole mounting in a 14-DIP package, while the TL054IDR employs surface-mount technology in a 14-SOIC package. Both parts share the same base product number (TL054) and LinCMOS™ series designation, confirming functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The TL054IDR is the manufacturer-recommended substitute for the TL054IN. Both parts are manufactured by Texas Instruments and maintain complete electrical equivalence across all specified parameters. The TL054IDR holds Active product status, ensuring continued availability and manufacturing support, whereas the TL054IN is designated Last Time Buy with limited inventory. Both parts comply with ROHS3 and REACH requirements, confirming regulatory equivalence.

The selection between these parts depends solely on circuit board design requirements. The TL054IN requires through-hole mounting and occupies a larger footprint suitable for breadboard prototyping or legacy PCB designs. The TL054IDR employs surface-mount technology in a 14-SOIC package, reducing board space and enabling automated assembly processes. Pin-to-pin electrical functionality is identical; therefore, substitution is valid when the target PCB layout accommodates the 14-SOIC package footprint and surface-mount assembly process.

Frequently Asked Questions (FAQ)

Q: Can the TL054IDR directly replace the TL054IN in an existing circuit?

A: Electrical substitution is complete. The TL054IDR maintains identical electrical specifications, supply voltage range, operating temperature range, and output characteristics. However, physical substitution requires PCB redesign to accommodate the 14-SOIC surface-mount package instead of the 14-DIP through-hole package. Pin functionality is equivalent; only the mounting method and physical footprint differ.

Q: Why is the TL054IN designated as Last Time Buy?

A: Last Time Buy status indicates Texas Instruments has discontinued production of the TL054IN. This designation provides customers with a final opportunity to purchase existing inventory before the part becomes unavailable. The TL054IDR, with identical electrical specifications and Active product status, is the recommended long-term alternative.

Q: Are there differences in reliability or performance between the 14-DIP and 14-SOIC packages?

A: Both packages are manufactured by Texas Instruments using the same die and internal circuitry. Electrical performance, operating temperature range, and reliability characteristics are identical. Package selection is determined by assembly method and PCB design requirements, not performance differences.

Q: What is the moisture sensitivity level difference between these parts?

A: The TL054IN lists Moisture Sensitivity Level as Not Applicable, while the TL054IDR specifies MSL 1 (Unlimited). MSL 1 indicates the surface-mount component has no moisture sensitivity restrictions and requires no special handling or baking procedures prior to reflow soldering.

Q: Can both parts operate across the full -40°C to 85°C temperature range?

A: Yes. Both the TL054IN and TL054IDR are specified for identical operating temperature ranges of -40°C to 85°C (TA). Thermal performance and temperature stability are equivalent across both package types.

Q: What is the significance of the LinCMOS™ series designation?

A: LinCMOS™ is a Texas Instruments product series combining JFET input stages with CMOS output stages. Both the TL054IN and TL054IDR belong to this series, confirming they share the same internal architecture, performance characteristics, and design heritage.
