Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TL074ACN is determined by strict equivalence across the following critical parameters:

Electrical Performance Criteria:

• Amplifier Type: J-FET input configuration
• Number of Circuits: Four independent operational amplifiers
• Slew Rate: 13 V/µs
• Gain Bandwidth Product: 5.25 MHz
• Input Bias Current: 65 pA
• Input Offset Voltage: 3 mV
• Supply Current: 1.4 mA per channel
• Supply Voltage Range: 10 V to 30 V

Physical & Mechanical Criteria:

• Package Type: 14-DIP (0.300", 7.62mm)
• Mounting Configuration: Through Hole
• Supplier Device Package: 14-PDIP

Compliance & Status Criteria:

• Manufacturer: Texas Instruments
• Product Status: Active
• RoHS Compliance: ROHS3 Compliant
• REACH Status: REACH Unaffected

The TL074IN qualifies as a direct substitute based on identical electrical specifications, package configuration, and compliance certifications. The primary distinction lies in operating temperature range, which does not affect substitution validity for applications within the TL074ACN's specified temperature window.

Parameter Comparison

Engineering Selection Recommendations

TL074IN as Direct Substitute:

The TL074IN is a valid direct substitute for the TL074ACN based on complete electrical and mechanical equivalence. Both devices share identical core specifications including J-FET amplifier topology, four-circuit configuration, slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, and supply voltage range. Package configuration and mounting type are identical, ensuring PCB compatibility without design modification.

Both parts maintain Active product status and comply with ROHS3 and REACH requirements, confirming regulatory alignment for current manufacturing standards.

The TL074IN features an extended operating temperature range (-40°C to 85°C) compared to the TL074ACN (0°C to 70°C). This extended range does not create substitution barriers; rather, it provides additional operational margin for applications operating within the TL074ACN's specified temperature window.

Selection between these parts should be based on inventory availability, lead time requirements, and application-specific temperature operating conditions. The TL074IN is suitable for designs requiring operation below 0°C or above 70°C, while both parts are functionally equivalent for applications within 0°C to 70°C.

Frequently Asked Questions (FAQ)

Q: Can TL074IN replace TL074ACN in existing circuit designs?

A: Yes. The TL074IN is a direct electrical and mechanical equivalent. No circuit modifications, PCB redesign, or firmware changes are required. Pin configuration, package footprint, and electrical performance are identical.

Q: What is the difference between TL074ACN and TL074IN?

A: The primary difference is operating temperature range. TL074ACN operates from 0°C to 70°C, while TL074IN operates from -40°C to 85°C. All other electrical specifications, package configuration, and compliance certifications are identical.

Q: Are both parts suitable for industrial temperature applications?

A: The TL074IN supports extended temperature operation (-40°C to 85°C) and is suitable for industrial temperature ranges. The TL074ACN is limited to 0°C to 70°C and is appropriate for commercial temperature applications. Selection depends on the specific operating temperature requirements of your application.

Q: Do both parts use the same PCB footprint?

A: Yes. Both TL074ACN and TL074IN use identical 14-DIP (0.300", 7.62mm) packages with through-hole mounting. PCB layouts are fully compatible without modification.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both TL074ACN and TL074IN are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: Which part should I select for new designs?

A: Selection is based on application requirements. For designs operating within 0°C to 70°C, either part is suitable. For applications requiring extended temperature operation or future temperature margin, TL074IN is the preferred choice. Verify inventory availability and lead times with your component supplier.
