TL054AIN Equivalent & Substitute Parts

Part Overview

The TL054AIN is a J-FET input operational amplifier manufactured by Texas Instruments, configured as a 4-circuit linear amplifier in a 14-DIP package. This device is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement.

The TL054AIN belongs to the LinCMOS™ series and is designed for applications requiring low input bias current and low input offset voltage characteristics typical of J-FET amplifier architectures. The obsolete status of this component necessitates identification of functionally equivalent alternatives that maintain electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The LT1058CN#PBF is a direct substitute for the obsolete TL054AIN based on matching package geometry, circuit configuration, and core electrical specifications. Both devices are ROHS3 compliant and carry identical moisture sensitivity ratings, ensuring regulatory and environmental compatibility.

Product Status Consideration:

The TL054AIN is classified as obsolete, while the LT1058CN#PBF maintains active product status from Analog Devices Inc. This status difference makes the LT1058CN#PBF the appropriate choice for new designs and ongoing procurement requirements.

Compliance and Certification:

Both parts carry ROHS3 compliance and REACH unaffected status. Both are classified under ECCN EAR99 and HTSUS 8542.33.0001, confirming regulatory equivalence for export and procurement purposes.

Operating Temperature Range:

The TL054AIN operates from -40°C to 85°C, while the LT1058CN#PBF operates from 0°C to 70°C. Applications requiring operation below 0°C or above 70°C must retain the TL054AIN or identify alternative solutions outside this substitute relationship.

Supply Voltage Consideration:

The TL054AIN accepts supply voltages from 10 V to 30 V. The LT1058CN#PBF requires minimum 20 V supply voltage. Designs operating at supply voltages between 10 V and 20 V cannot use the LT1058CN#PBF as a substitute.

Frequently Asked Questions (FAQ)

Q: Can the LT1058CN#PBF replace the TL054AIN in all applications?

A: The LT1058CN#PBF is a functional substitute for applications operating at supply voltages of 20 V or higher and within the 0°C to 70°C temperature range. Applications requiring operation below 20 V supply voltage or outside the 0°C to 70°C temperature range require alternative solutions.

Q: Are the package dimensions identical between TL054AIN and LT1058CN#PBF?

A: Both devices use 14-DIP (0.300", 7.62mm) packages with through-hole mounting. Pin-to-pin compatibility is confirmed for direct board-level substitution.

Q: What are the key electrical differences between these parts?

A: The LT1058CN#PBF provides superior input bias current (7 pA vs. 30 pA), lower input offset voltage (250 µV vs. 500 µV), higher gain bandwidth product (5 MHz vs. 2.7 MHz), and significantly lower supply current (1.7 mA vs. 8.4 mA per 4 channels). The TL054AIN offers higher slew rate (17.8 V/µs vs. 13 V/µs) and wider supply voltage range (10 V to 30 V vs. 20 V to 36 V).

Q: Is the LT1058CN#PBF available in the same packaging format?

A: Yes. The LT1058CN#PBF is supplied in 14-PDIP packaging, equivalent to the 14-DIP form factor of the TL054AIN. Tube packaging is specified for the LT1058CN#PBF.

Q: What compliance certifications apply to both parts?

A: Both the TL054AIN and LT1058CN#PBF are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Moisture sensitivity level is 1 (Unlimited) for both devices.

Q: Why is the TL054AIN classified as obsolete?

A: The TL054AIN is an obsolete product from Texas Instruments. The LT1058CN#PBF from Analog Devices Inc. maintains active product status and serves as the recommended substitute for ongoing design support and procurement.
