Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL054AING4 is determined by strict equivalence in the following critical parameters:

Mandatory Equivalence Criteria:

• Amplifier Type: J-FET input configuration
• Number of Circuits: 4 operational amplifiers per package
• Package / Case: 14-DIP (0.300", 7.62mm) form factor
• Mounting Type: Through Hole

Functional Compatibility Parameters:

• Supply voltage range must encompass or exceed the original specification
• Input bias current, input offset voltage, slew rate, and gain bandwidth product must be within acceptable operating margins for the target application
• Output current capability must support the load requirements

The LT1058CN#PBF from Analog Devices Inc. satisfies all mandatory equivalence criteria and maintains functional compatibility through superior electrical performance characteristics, including lower input bias current (7 pA vs. 30 pA), reduced input offset voltage (250 µV vs. 500 µV), and higher gain bandwidth product (5 MHz vs. 2.7 MHz).

Parameter Comparison

Engineering Selection Recommendations

The LT1058CN#PBF is the manufacturer-recommended substitute for the TL054AING4. Both devices are ROHS3 compliant and carry MSL rating of 1 (Unlimited), ensuring equivalent environmental and regulatory compliance.

The LT1058CN#PBF is currently in active production status, whereas the TL054AING4 is obsolete. This distinction is critical for long-term supply chain reliability and design continuity.

The LT1058CN#PBF demonstrates superior electrical performance across multiple parameters: input bias current is reduced by 77% (7 pA vs. 30 pA), input offset voltage is reduced by 50% (250 µV vs. 500 µV), and gain bandwidth product is increased by 85% (5 MHz vs. 2.7 MHz). Supply current consumption is reduced by 80% (1.7 mA vs. 8.4 mA across four channels).

The minimum supply voltage requirement for the LT1058CN#PBF is 20V, compared to 10V for the TL054AING4. Applications operating below 20V supply voltage require design modification or alternative component selection. The maximum supply voltage for the LT1058CN#PBF extends to 36V, providing additional operational margin.

The operating temperature range of the LT1058CN#PBF (0°C ~ 70°C) is narrower than the TL054AING4 (-40°C ~ 85°C). Applications requiring extended temperature operation below 0°C or above 70°C must evaluate alternative solutions.

Both devices share identical package geometry (14-DIP, 0.300", 7.62mm) and through-hole mounting type, enabling direct socket substitution without PCB redesign.

Frequently Asked Questions (FAQ)

Q: Can the LT1058CN#PBF be used as a direct replacement for the TL054AING4 in existing designs?

A: The LT1058CN#PBF is pin-compatible and shares identical package geometry with the TL054AING4, enabling direct socket substitution. However, design verification is required for applications with supply voltages below 20V or operating temperatures below 0°C or above 70°C, as the LT1058CN#PBF has different supply voltage and temperature specifications.

Q: What are the key differences between these two J-FET amplifiers?

A: The primary differences are product status (LT1058CN#PBF is active; TL054AING4 is obsolete), supply voltage range (LT1058CN#PBF requires minimum 20V vs. 10V for TL054AING4), operating temperature range (LT1058CN#PBF: 0°C ~ 70°C vs. TL054AING4: -40°C ~ 85°C), and electrical performance metrics. The LT1058CN#PBF offers superior input bias current, input offset voltage, and gain bandwidth product specifications.

Q: Are both devices available in the same package type?

A: Yes. Both the TL054AING4 and LT1058CN#PBF are packaged in 14-DIP (0.300", 7.62mm) through-hole format, allowing direct PCB substitution without layout modifications.

Q: What is the significance of the obsolete status of the TL054AING4?

A: Obsolete status indicates that Texas Instruments has discontinued production and support for the TL054AING4. This creates supply chain risk for new production and long-term availability concerns. The LT1058CN#PBF, with active product status, provides assured supply continuity and manufacturer support.

Q: Do both devices meet the same environmental compliance standards?

A: Yes. Both the TL054AING4 and LT1058CN#PBF are ROHS3 compliant and carry MSL rating of 1 (Unlimited), meeting equivalent environmental and regulatory requirements.

Q: What supply voltage range must be considered when substituting the LT1058CN#PBF?

A: The LT1058CN#PBF operates with a minimum supply voltage of 20V and maximum of 36V. Applications designed for the TL054AING4 operating below 20V supply voltage require circuit redesign or alternative component selection, as the LT1058CN#PBF cannot operate in this voltage range.

Q: How does the operating temperature range affect component selection?

A: The LT1058CN#PBF operates from 0°C to 70°C, whereas the TL054AING4 operates from -40°C to 85°C. Applications requiring operation below 0°C or above 70°C must evaluate alternative components or implement thermal management strategies to maintain operation within the LT1058CN#PBF specifications.
