TL054ACN Equivalent & Substitute Parts

Part Overview

The TL054ACN is a J-FET input operational amplifier manufactured by Texas Instruments, configured as a 4-circuit linear amplifier in a 14-DIP through-hole package. This device is classified as Last Time Buy, indicating discontinued production with limited availability. The TL054ACN operates across a 10V to 30V supply span and is suitable for applications requiring low input bias current and moderate bandwidth performance.

Finding equivalent and substitute parts is necessary due to the Last Time Buy status of the TL054ACN. Alternative parts with identical or compatible electrical and mechanical specifications ensure design continuity and long-term component availability for production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL054ACN is determined by strict alignment of electrical and mechanical parameters. The following criteria define valid substitutes:

Primary Substitution Criteria:

• Amplifier Type: J-FET input configuration
• Number of Circuits: 4 independent amplifier circuits
• Package Type: 14-pin DIP or equivalent surface-mount variant (14-SOIC)
• Mounting Type: Through-hole or surface-mount compatibility with circuit board design
• Supply Voltage Range: Minimum 10V to 30V span compatibility
• Operating Temperature: 0°C to 70°C range

Electrical Parameter Alignment: Substitute parts must maintain the core J-FET amplifier architecture. Input bias current, input offset voltage, slew rate, and gain bandwidth product are secondary parameters that may vary within acceptable engineering tolerances for the application category.

Packaging Consideration: The TL054ACN uses through-hole 14-DIP packaging. Surface-mount alternatives (14-SOIC) are classified as substitutes when electrical specifications align, provided circuit board design accommodates the different mounting technology.

Parameter Comparison

Engineering Selection Recommendations

TL054ACDR Selection: The TL054ACDR is the manufacturer-recommended substitute from Texas Instruments. It maintains identical electrical specifications (slew rate 17.8V/µs, gain bandwidth product 2.7MHz, input bias current 30pA, input offset voltage 500µV, and supply current 8.4mA across 4 channels). The primary difference is packaging: TL054ACDR uses 14-SOIC surface-mount configuration versus the through-hole 14-DIP of the TL054ACN. This substitute is appropriate for new designs or applications where surface-mount technology is acceptable. Product status is Active, ensuring continued availability. RoHS3 compliance and REACH Unaffected status match the main part.

LT1058CN#PBF Selection: The LT1058CN#PBF is an Analog Devices equivalent offering J-FET amplifier architecture in 4-circuit configuration with through-hole 14-DIP packaging, matching the TL054ACN form factor. Electrical performance differs: the LT1058CN#PBF provides superior specifications including lower input bias current (7pA versus 30pA), lower input offset voltage (250µV versus 500µV), higher gain bandwidth product (5MHz versus 2.7MHz), and significantly lower supply current (1.7mA versus 8.4mA across 4 channels). The minimum supply voltage is 20V (versus 10V for TL054ACN), and maximum is 36V (versus 30V). Product status is Active with higher inventory availability (2588 pcs). This substitute is suitable for applications where improved performance characteristics and lower power consumption are beneficial, provided the 20V minimum supply voltage requirement is met.

Compliance and Certification: All substitute parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment with the main part. Selection between substitutes depends on circuit board design constraints (through-hole versus surface-mount) and application performance requirements.

Frequently Asked Questions (FAQ)

Q: Can the TL054ACDR replace the TL054ACN in existing through-hole circuit boards?

A: No. The TL054ACDR uses 14-SOIC surface-mount packaging, while the TL054ACN uses 14-DIP through-hole packaging. Circuit board redesign is required to accommodate the different pin configuration and mounting technology. For through-hole applications, the LT1058CN#PBF is the appropriate substitute.

Q: What is the key difference between TL054ACDR and LT1058CN#PBF?

A: The TL054ACDR is a surface-mount variant (14-SOIC) of the TL054ACN with identical electrical specifications. The LT1058CN#PBF is a through-hole alternative (14-DIP) from a different manufacturer (Analog Devices) with improved electrical performance, including lower input bias current, lower input offset voltage, higher bandwidth, and lower power consumption. The LT1058CN#PBF requires a minimum 20V supply voltage, compared to 10V for the TL054ACN.

Q: Is the LT1058CN#PBF compatible with the TL054ACN in terms of pin configuration?

A: Yes. Both devices use 14-DIP through-hole packaging with identical pin assignments for J-FET quad amplifier circuits. Pin-for-pin substitution is possible. However, the different electrical specifications (particularly the 20V minimum supply voltage) must be verified against circuit design requirements.

Q: Why does the LT1058CN#PBF have lower supply current than the TL054ACN?

A: The LT1058CN#PBF is specified at 1.7mA total supply current across 4 channels, compared to 8.4mA for the TL054ACN. This reflects different internal circuit design and biasing approaches within the J-FET amplifier architecture. Both devices are functionally equivalent 4-circuit amplifiers, but the LT1058CN#PBF achieves lower power consumption.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The TL054ACDR and LT1058CN#PBF are both ROHS3 compliant, matching the compliance status of the main part TL054ACN. All three parts are REACH Unaffected.

Q: What is the inventory status of these substitute parts?

A: TL054ACN (Last Time Buy): 1480 pcs. TL054ACDR (Active): 1116 pcs. LT1058CN#PBF (Active): 2588 pcs. The LT1058CN#PBF offers the highest inventory availability with Active product status.

Q: Can I use the TL054ACDR in a design that currently uses the TL054ACN?

A: Electrical substitution is direct; however, circuit board redesign is required due to packaging differences. The TL054ACDR is suitable for new designs or board revisions where surface-mount technology is preferred or required.
