Key Parameters

Substitute Part Grouping Explanation

Substitution for TL074ACNG4 is determined by strict adherence to these key parameters:

• Amplifier Type: J-FET
• Number of Circuits: 4
• Slew Rate
• Gain Bandwidth Product
• Current - Input Bias
• Voltage - Input Offset
• Operating Temperature Range
• Package Type and Mounting: 14-DIP (0.300", 7.62mm), Through Hole
• Supply Voltage Range
• RoHS and REACH Compliance
• Moisture Sensitivity Level (MSL)

A valid substitute must match or exceed electrical characteristics within the stated ranges and must be packaged identically for direct PCB replacement.

Parameter Comparison

Engineering Selection Recommendations

Substitute parts such as TL074ACN by STMicroelectronics have an equivalent amplifier type, circuit count, and pin-compatible DIP package. Both the TL074ACNG4 and TL074ACN are RoHS3 compliant, REACH unaffected, and rated MSL 1 (Unlimited), supporting lead-free compliant manufacturing and unrestricted shelf life. Substitute selections should be limited to models meeting these status and compliance requirements.

Frequently Asked Questions (FAQ)

Q1: What parameters must match when substituting TL074ACNG4?
A1: The substitute must have the same amplifier type (J-FET), number of circuits, package type (14-DIP, through-hole), and should closely align on slew rate, gain bandwidth, input bias current, voltage input offset, supply current, and permissible supply voltage range.

Q2: Is the 14-DIP package of TL074ACN physically identical to TL074ACNG4?
A2: Both parts are specified in a 14-DIP (0.300", 7.62mm) through-hole package compatible with standard DIP sockets and PCB layouts.

Q3: Do substitute parts conform to the same environmental and compliance standards?
A3: Both TL074ACNG4 and TL074ACN are ROHS3 compliant, REACH unaffected, and have an MSL rating of 1 (Unlimited).

Q4: What is the main reason for considering these substitute parts?
A4: The product status of TL074ACNG4 is obsolete, making alternatives such as TL074ACN necessary for ongoing designs and maintenance if identical performance and form factor are required.

Q5: Are operating temperature ranges consistent across both parts?
A5: Both amplifiers operate across the specified 0°C ~ 70°C temperature range.
