Substitute Part Grouping Explanation

Substitution of the TL084ING4 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Criteria:

• Amplifier Type: J-FET input configuration
• Number of Circuits: 4 independent operational amplifiers
• Package / Case: 14-DIP form factor with 0.300" (7.62mm) pitch
• Mounting Type: Through Hole
• Gain Bandwidth Product: 4 MHz
• Voltage - Input Offset: 3 mV maximum
• Current - Output / Channel: 40 mA minimum

Allowable Parameter Variations: Substitute parts may exceed the TL084ING4 specifications in the following parameters without compromising functional compatibility:

• Slew Rate: Substitute may be equal to or greater than 13 V/µs
• Current - Input Bias: Substitute may be equal to or less than 30 pA
• Voltage - Supply Span: Substitute range may encompass or exceed 10 V to 30 V
• Operating Temperature: Substitute range may encompass or exceed -40°C to 85°C

The TL084IN manufactured by STMicroelectronics meets all mandatory matching criteria and demonstrates allowable parameter improvements, qualifying it as a direct substitute for the TL084ING4.

Engineering Selection Recommendations

The TL084IN from STMicroelectronics is a direct functional substitute for the obsolete TL084ING4. Both components share identical pinout, package geometry, and core electrical specifications. The TL084IN demonstrates improved performance characteristics across slew rate, input bias current, and supply voltage range, while maintaining full compatibility with existing circuit designs.

The TL084IN carries AEC-Q100 automotive qualification and operates across an extended temperature range (-40°C to 125°C), providing enhanced reliability margins for industrial applications. Both components maintain ROHS3 compliance and identical moisture sensitivity classification (MSL 1).

Selection of the TL084IN eliminates obsolescence risk while providing measurable performance improvements without requiring circuit redesign or board layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the TL084IN directly replace the TL084ING4 without circuit modifications?

A: Yes. The TL084IN is pin-compatible and functionally equivalent to the TL084ING4. Both devices are housed in 14-DIP packages with identical pinout and electrical characteristics. No circuit modifications are required for direct substitution.

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

A: The TL084IN offers improved specifications in three areas: slew rate (16 V/µs versus 13 V/µs), input bias current (20 pA versus 30 pA), and supply voltage range (6 V to 36 V versus 10 V to 30 V). The TL084IN also supports an extended operating temperature range (-40°C to 125°C versus -40°C to 85°C) and includes AEC-Q100 automotive qualification.

Q: Are there any package or mounting differences?

A: No. Both the TL084ING4 and TL084IN use identical 14-DIP (0.300", 7.62mm) through-hole packages. PCB footprints and mounting procedures are identical.

Q: Does the TL084IN meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (unlimited moisture sensitivity). The TL084IN additionally carries AEC-Q100 automotive qualification.

Q: What is the inventory status of the TL084IN?

A: The TL084IN is available with 2348 pieces in new original stock, providing immediate procurement availability compared to the obsolete TL084ING4 status.
