TL074ING4 Equivalent & Substitute Parts

Part Overview

The TL074ING4 is a J-FET input operational amplifier containing four independent circuits in a 14-pin DIP package. This device is designed for applications requiring low input bias current and low input offset voltage characteristics typical of J-FET amplifier designs. The TL074ING4 is discontinued at DiGi Electronics, necessitating identification of equivalent substitute components that maintain electrical and mechanical compatibility for ongoing system support and new designs.

Parameter Comparison

Engineering Selection Recommendations

The TL074IN is the direct equivalent substitute for the TL074ING4. Both components are manufactured by Texas Instruments and share identical electrical specifications across all measured parameters. The primary distinction is product status: the TL074ING4 is discontinued at DiGi Electronics, while the TL074IN maintains active product status with higher inventory availability (4068 pieces in stock versus 1088 pieces for the TL074ING4).

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and legacy system support. The packaging difference (tube versus unspecified for the main part) does not affect electrical or mechanical compatibility, as both utilize the identical 14-DIP through-hole package format.

For applications currently using the TL074ING4, direct substitution with the TL074IN requires no circuit modifications, PCB layout changes, or firmware updates. Pin-to-pin compatibility is complete.

Frequently Asked Questions (FAQ)

Q: Can the TL074IN replace the TL074ING4 in existing designs?

A: Yes. The TL074IN is electrically and mechanically equivalent to the TL074ING4. All electrical parameters, pin configuration, and package dimensions are identical. Direct substitution is possible without circuit redesign.

Q: What is the difference between TL074ING4 and TL074IN?

A: The primary difference is product status and packaging format. The TL074ING4 is discontinued at DiGi Electronics, while the TL074IN is an active product. The TL074IN is supplied in tube packaging, whereas the TL074ING4 packaging format is not specified. Both use the 14-DIP through-hole package.

Q: Are there any compliance differences between these parts?

A: No. Both the TL074ING4 and TL074IN are ROHS3 compliant and REACH unaffected. They meet identical regulatory requirements.

Q: What are the key electrical parameters that define substitution for the TL074 series?

A: Substitution is determined by J-FET amplifier type, four-circuit configuration, 13 V/µs slew rate, 5.25 MHz gain bandwidth product, 65 pA input bias current, 3 mV input offset voltage, 1.4 mA supply current per channel, 10 V to 30 V supply range, and -40°C to 85°C operating temperature.

Q: Is the 14-DIP package compatible with standard through-hole PCB layouts?

A: Yes. Both the TL074ING4 and TL074IN use the 14-DIP (0.300", 7.62mm) through-hole package, which is compatible with standard DIP sockets and through-hole PCB designs.

Q: Can I use the TL074IN in high-temperature applications?

A: The TL074IN operates across the -40°C to 85°C temperature range, identical to the TL074ING4. Applications requiring operation beyond 85°C require alternative component selection.
