Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TL074CPWR

The TL074CPWR is the recommended direct substitute for TL074CPW. Both parts are manufactured by Texas Instruments and share identical electrical specifications including 13 V/µs slew rate, 5.25 MHz gain bandwidth product, 65 pA input bias current, and 3 mV input offset voltage. The TL074CPWR maintains the same 14-TSSOP package and surface mount configuration. The primary difference is packaging format: TL074CPWR is supplied in Cut Tape (CT) & Digi-Reel format with significantly higher inventory availability (31,027 pcs) compared to TL074CPW (1,704 pcs). Product status is Active, ensuring long-term supply continuity. This substitute requires no circuit redesign or performance verification.

Secondary Substitutes: ADTL084ARUZ, TL084CPT, TL084IPT

These J-FET amplifiers provide enhanced electrical performance relative to TL074CPW while maintaining the same package and circuit count. ADTL084ARUZ offers superior input bias current (2 pA versus 65 pA) and higher slew rate (20 V/µs versus 13 V/µs), with extended operating temperature range (-40°C to 125°C). TL084CPT and TL084IPT provide intermediate performance with 16 V/µs slew rate and 20 pA input bias current. All three parts support extended supply voltage range (up to 36 V maximum). These substitutes are suitable for applications where improved performance specifications provide design margin. TL084CPT and TL084IPT carry AEC-Q100 automotive qualification.

Alternative Substitute: ADA4077-4ARUZ, ADA4077-4ARUZ-R7, ADA4077-4ARUZ-RL

The ADA4077 series (Analog Devices Inc.) represents a General Purpose amplifier topology alternative. These parts share the 14-TSSOP package and four-circuit configuration but operate with fundamentally different input characteristics: 400 pA input bias current (versus 65 pA) and 15 µV input offset voltage (versus 3 mV). Slew rate is reduced to 1.2 V/µs and gain bandwidth product to 3.6 MHz. Supply voltage minimum is 5 V (versus 10 V). These substitutes are applicable only in applications where the relaxed input bias current and offset voltage specifications are acceptable. Extended operating temperature range (-40°C to 125°C) and lower supply current (0.4 mA per channel) provide advantages in temperature-critical and power-constrained designs.

Compliance and Certification:

All substitute parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating. TL084CPT and TL084IPT include AEC-Q100 automotive qualification, suitable for automotive-grade applications. All parts are REACH Unaffected and classified under ECCN EAR99.

Frequently Asked Questions (FAQ)

Q1: Can TL074CPWR be used as a direct replacement for TL074CPW without circuit modification?

A: Yes. TL074CPWR is electrically and mechanically identical to TL074CPW. Both parts share the same J-FET amplifier topology, four-circuit configuration, 14-TSSOP package, and all electrical specifications including slew rate, gain bandwidth product, input bias current, and input offset voltage. The only difference is packaging format (Cut Tape & Digi-Reel versus Tube). No circuit redesign or performance verification is required.

Q2: What are the key differences between J-FET substitutes (ADTL084ARUZ, TL084CPT) and General Purpose substitutes (ADA4077 series)?

A: J-FET substitutes maintain the same amplifier topology as TL074CPW with low input bias current (2–20 pA range) and moderate input offset voltage (1.5–3 mV). General Purpose substitutes (ADA4077 series) use a different topology with higher input bias current (400 pA) and significantly lower input offset voltage (15 µV). Selection depends on application requirements: J-FET types are preferred for high-impedance signal sources and precision applications; General Purpose types are suitable for lower-impedance sources and applications tolerating higher bias current.

Q3: Is ADTL084ARUZ a superior substitute to TL074CPW?

A: ADTL084ARUZ provides enhanced electrical performance in specific parameters: input bias current is reduced to 2 pA (versus 65 pA), slew rate is increased to 20 V/µs (versus 13 V/µs), and operating temperature range is extended to -40°C to 125°C (versus 0°C to 70°C). However, these improvements are not universally beneficial. Applications designed for TL074CPW specifications may not require this enhanced performance. ADTL084ARUZ is suitable when improved performance specifications provide design margin or when extended temperature operation is required.

Q4: Can ADA4077-4ARUZ be used in applications originally designed for TL074CPW?

A: ADA4077-4ARUZ can be used only if the application tolerates significantly different input characteristics. The 400 pA input bias current (versus 65 pA) and 15 µV input offset voltage (versus 3 mV) represent fundamental differences in amplifier behavior. Applications with high-impedance inputs or precision requirements may experience performance degradation. Applications with low-impedance inputs and relaxed offset voltage tolerance can accommodate this substitute. Verification testing is required before deployment in production designs.

Q5: What is the significance of the 14-TSSOP package specification for substitution?

A: The 14-TSSOP package is a surface mount form factor with standardized pin configuration and mechanical dimensions (0.173" width, 4.40mm). All listed substitutes use this identical package, ensuring mechanical compatibility with existing PCB layouts and assembly processes. No PCB redesign is required when substituting between parts with the same 14-TSSOP designation.

Q6: Why does TL074CPW have Last Time Buy status?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of TL074CPW and will not accept new orders beyond a specified cutoff date. Existing inventory is limited (1,704 pcs). This status necessitates identifying substitute parts for long-term design continuity. TL074CPWR (Active status, 31,027 pcs inventory) is the recommended alternative to ensure supply availability.

Q7: Are there temperature range considerations when selecting a substitute?

A: Yes. TL074CPW operates from 0°C to 70°C. ADTL084ARUZ, ADA4077 series, and TL084IPT extend this range to -40°C to 125°C, providing broader environmental coverage. TL084CPT operates from 0°C to 70°C, matching TL074CPW. Applications requiring extended temperature operation should select substitutes with appropriate temperature ratings. Applications limited to 0°C to 70°C can use any substitute without temperature-related constraints.

Q8: What packaging format differences exist between TL074CPW and TL074CPWR?

A: TL074CPW is supplied in Tube packaging; TL074CPWR is supplied in Cut Tape (CT) & Digi-Reel format. Both are surface mount 14-TSSOP packages with identical electrical specifications. Tube packaging is typically used for lower-volume orders; Cut Tape & Digi-Reel is standard for automated assembly processes. The packaging format does not affect electrical performance or PCB compatibility.

Q9: Which substitute offers the lowest power consumption?

A: ADA4077 series (all variants) offers the lowest supply current at 0.4 mA per four-channel configuration, compared to 1.4 mA for TL074CPW and 1.2 mA for ADTL084ARUZ. This 65–70% reduction in supply current makes ADA4077 series suitable for battery-powered and power-constrained applications. However, this advantage must be weighed against the higher input bias current (400 pA) and different amplifier topology.

Q10: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitutes (TL074CPWR, ADA4077-4ARUZ, ADA4077-4ARUZ-R7, ADA4077-4ARUZ-RL, ADTL084ARUZ, TL084CPT, TL084IPT) are ROHS3 Compliant with MSL Level 1 (Unlimited) moisture sensitivity rating. All are REACH Unaffected and classified under ECCN EAR99. Compliance status is uniform across all substitutes.
