Substitute Part Grouping Explanation

Substitution of the TL064ING4 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 Type: 14-DIP through-hole form factor
• Slew Rate: 3.5 V/µs
• Gain Bandwidth Product: 1 MHz
• Input Bias Current: 30 pA
• Input Offset Voltage: 3 mV
• Output Current per Channel: 20 mA
• Supply Current: 200 µA (x4 channels)

Allowable Parameter Variations:

• Voltage Supply Span: Substitute minimum ≥ 6 V; substitute maximum ≥ 30 V
• Operating Temperature: Substitute range must encompass -40°C to 85°C minimum

The TL064IN from STMicroelectronics meets all mandatory criteria and allowable variations, qualifying as a direct substitute for the TL064ING4.

Engineering Selection Recommendations

The TL064IN manufactured by STMicroelectronics is the manufacturer-recommended substitute for the obsolete TL064ING4. Both devices maintain identical electrical performance specifications across all critical parameters including slew rate, gain-bandwidth product, input bias current, and output current capacity.

The TL064IN provides enhanced operational margins through an extended supply voltage range (6 V to 36 V versus 10 V to 30 V) and extended operating temperature range (-40°C to 105°C versus -40°C to 85°C). These expanded specifications ensure compatibility in applications originally designed for the TL064ING4 while supporting broader environmental conditions.

Both components are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99, maintaining regulatory equivalence. The identical 14-DIP through-hole package ensures direct mechanical and electrical compatibility without PCB redesign.

Frequently Asked Questions (FAQ)

Q: Can the TL064IN directly replace the TL064ING4 without circuit modification?

A: Yes. The TL064IN is electrically and mechanically equivalent to the TL064ING4. Identical pin configuration, package footprint, and electrical specifications enable direct substitution without circuit redesign or PCB layout changes.

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

A: The TL064IN offers extended supply voltage range (minimum 6 V versus 10 V; maximum 36 V versus 30 V) and extended operating temperature range (-40°C to 105°C versus -40°C to 85°C). All core amplifier specifications remain identical.

Q: Are there any compliance or certification differences?

A: No. Both the TL064ING4 and TL064IN maintain identical RoHS3 compliance, REACH unaffected status, and ECCN EAR99 classification.

Q: Why is the TL064ING4 classified as obsolete?

A: The TL064ING4 is no longer in active production. The TL064IN serves as the current production equivalent from STMicroelectronics.

Q: What is the significance of the 14-DIP package specification?

A: The 14-DIP (Dual Inline Package) with 0.300" (7.62 mm) row spacing is a through-hole component format. Both the TL064ING4 and TL064IN use identical package dimensions, ensuring compatibility with existing PCB designs without modification.

Q: Can the TL064IN be used in applications requiring the full -40°C to 85°C temperature range?

A: Yes. The TL064IN operating range of -40°C to 105°C fully encompasses the -40°C to 85°C requirement of the original TL064ING4 specification.
