Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TL074MDREP is determined by the following critical parameters:

Package Compatibility: All substitute parts must use the 14-SOIC (0.154", 3.90mm Width) surface mount package to ensure mechanical and electrical compatibility with existing PCB layouts.

Circuit Configuration: All substitute parts must provide 4 operational amplifier circuits within a single package.

Supply Voltage Range: Substitute parts must support the minimum 7V supply requirement of the TL074MDREP. Parts with lower minimum supply voltage (3V or 8V) remain compatible as they exceed the 7V threshold.

Output Current Capability: The TL074MDREP delivers 10 mA per channel. Substitute parts with equal or greater output current per channel (10 mA or higher) maintain functional equivalence.

Temperature Operating Range: The TL074MDREP operates from -55°C to 125°C. Substitute parts with narrower temperature ranges remain compatible if the application operates within the substitute part's specified range.

Compliance & Certification: All substitute parts maintain RoHS3 compliance and REACH unaffected status, matching the regulatory profile of the main part.

Substitutes are grouped into two categories: J-FET amplifiers (ADTL084ARZ-REEL) and general-purpose amplifiers (MC34074VDR2G, NCV34074VDR2G, LM324EDR2G, AS324MTR-E1). J-FET substitutes preserve the low input bias current characteristic. General-purpose substitutes offer alternative performance profiles suitable for applications where J-FET input characteristics are not mandatory.

Engineering Selection Recommendations

ADTL084ARZ-REEL (Analog Devices Inc.): This J-FET amplifier substitute maintains the low input bias current characteristic of the TL074MDREP while offering superior performance metrics including 20 V/µs slew rate and 5 MHz gain bandwidth product. The ADTL084ARZ-REEL operates across -40°C to 125°C, covering the upper portion of the TL074MDREP temperature range. This substitute is suitable for applications prioritizing low input bias current and enhanced frequency response. Minimum supply voltage is 8V, which exceeds the TL074MDREP requirement of 7V. RoHS3 compliance and MSL 1 rating match the main part specifications.

MC34074VDR2G (onsemi): This general-purpose amplifier provides 13 V/µs slew rate and 4.5 MHz gain bandwidth product, matching the TL074MDREP slew rate specification. Operating temperature range extends from -40°C to 125°C. Output current per channel is 30 mA, exceeding the TL074MDREP 10 mA specification. Supply voltage range spans 3V to 44V, accommodating the 7V minimum requirement. RoHS3 compliance and MSL 1 rating are maintained. This substitute is applicable when general-purpose amplifier characteristics are acceptable and extended supply voltage range is beneficial.

NCV34074VDR2G (onsemi): This general-purpose amplifier shares identical electrical specifications with MC34074VDR2G, including 13 V/µs slew rate, 4.5 MHz gain bandwidth product, and 30 mA output current per channel. Operating temperature range is -40°C to 125°C. Supply voltage range spans 3V to 44V. RoHS3 compliance and MSL 1 rating are maintained. This substitute is functionally equivalent to MC34074VDR2G and is applicable in identical application scenarios.

LM324EDR2G (onsemi): This general-purpose amplifier operates across 0°C to 70°C, providing a narrower temperature range than the TL074MDREP. Output current per channel is 40 mA. Supply voltage range spans 3V to 32V, accommodating the 7V minimum requirement. RoHS3 compliance and MSL 1 rating are maintained. This substitute is suitable for applications operating within the 0°C to 70°C temperature window where general-purpose amplifier performance is acceptable.

AS324MTR-E1 (Diodes Incorporated): This general-purpose amplifier operates across -40°C to 85°C, providing coverage of the TL074MDREP temperature range except below -40°C. Output current per channel is 40 mA. Supply voltage range spans 3V to 36V, accommodating the 7V minimum requirement. RoHS3 compliance is maintained; however, MSL rating is 3 (168 Hours), indicating moisture sensitivity requirements during storage and handling. This substitute is applicable for applications within the -40°C to 85°C range where moisture control procedures are implemented.

All substitute parts maintain Active product status and regulatory compliance (RoHS3, REACH unaffected, EAR99 ECCN classification). Selection among substitutes depends on application-specific requirements for temperature range, output current capability, input bias current characteristics, and moisture sensitivity handling procedures.

Frequently Asked Questions (FAQ)

Q: Can the ADTL084ARZ-REEL replace the TL074MDREP in all applications?

A: The ADTL084ARZ-REEL is mechanically and electrically compatible with the TL074MDREP in the 14-SOIC package. Both are J-FET amplifiers with 4 circuits. The ADTL084ARZ-REEL offers superior performance (20 V/µs slew rate vs. 13 V/µs, 5 MHz vs. 3 MHz gain bandwidth product) and lower input bias current (2 pA vs. 65 pA). The minimum supply voltage is 8V instead of 7V. Substitution is valid when the application operates at 8V or higher supply voltage and the enhanced performance characteristics are acceptable or beneficial.

Q: What is the primary difference between J-FET and general-purpose amplifier substitutes?

A: J-FET amplifiers (ADTL084ARZ-REEL) feature extremely low input bias current (2 pA), making them suitable for high-impedance input applications. General-purpose amplifiers (MC34074VDR2G, NCV34074VDR2G, LM324EDR2G, AS324MTR-E1) have higher input bias current (20 nA to 100 nA) but offer broader supply voltage ranges and higher output current capability. Selection depends on whether low input bias current is a functional requirement or whether general-purpose performance is sufficient.

Q: Are all substitute parts pin-compatible with the TL074MDREP?

A: Yes. All substitute parts use the 14-SOIC (0.154", 3.90mm Width) package with identical pinout configuration for 4-circuit operational amplifiers. Direct PCB substitution is mechanically and electrically feasible without layout modifications.

Q: Which substitute part has the lowest operating temperature limit?

A: The LM324EDR2G operates from 0°C to 70°C, the most restrictive lower temperature limit among all substitutes. The TL074MDREP operates from -55°C to 125°C. If operation below 0°C is required, LM324EDR2G is not suitable. The ADTL084ARZ-REEL, MC34074VDR2G, NCV34074VDR2G, and AS324MTR-E1 all support -40°C minimum operation.

Q: What is the significance of the MSL 3 rating for AS324MTR-E1?

A: MSL 3 (168 Hours) indicates that AS324MTR-E1 has moisture sensitivity requirements. The component must be stored in controlled humidity conditions and has a 168-hour floor life after moisture exposure. The TL074MDREP and most other substitutes have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. AS324MTR-E1 requires implementation of moisture control procedures during storage, handling, and assembly.

Q: Can the LM324EDR2G be used in applications requiring -55°C operation?

A: No. The LM324EDR2G operates from 0°C to 70°C and is not rated for operation below 0°C. Applications requiring -55°C operation must use the TL074MDREP, ADTL084ARZ-REEL, MC34074VDR2G, NCV34074VDR2G, or AS324MTR-E1 (which supports -40°C minimum).

Q: Which substitute provides the highest output current per channel?

A: Both LM324EDR2G and AS324MTR-E1 provide 40 mA output current per channel, the highest among all substitutes. The TL074MDREP provides 10 mA per channel. Higher output current capability allows driving lower impedance loads or multiple stages without additional buffering.

Q: Is the supply voltage range difference between substitutes significant?

A: Yes. The TL074MDREP requires minimum 7V supply. MC34074VDR2G, NCV34074VDR2G, LM324EDR2G, and AS324MTR-E1 support 3V minimum supply, enabling operation in low-voltage applications. ADTL084ARZ-REEL requires 8V minimum. Maximum supply voltage ranges from 32V (LM324EDR2G) to 44V (MC34074VDR2G, NCV34074VDR2G). Application power supply specifications determine which substitutes are compatible.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (ADTL084ARZ-REEL, MC34074VDR2G, NCV34074VDR2G, LM324EDR2G, AS324MTR-E1) are RoHS3 compliant, matching the TL074MDREP regulatory status. All maintain REACH unaffected status and EAR99 ECCN classification.
