Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: TLC082IDR

The TLC082IDR represents the optimal substitute for the obsolete TLC082IDRG4. This part maintains identical electrical specifications across all critical parameters: 19V/µs slew rate, 10 MHz gain bandwidth product, 3 pA input bias current, and 390 µV input offset voltage. The TLC082IDR operates within the same supply voltage range (4.5V to 16V) and temperature range (-40°C to 125°C). Critically, the TLC082IDR holds active product status, ensuring long-term availability and supply chain continuity. Both parts are ROHS3 compliant and packaged in 8-SOIC (3.90mm width) surface mount configuration. The packaging format is identical, permitting direct board-level substitution without design modification.

Secondary Recommendation: MC33078DR2G

The MC33078DR2G from onsemi provides an alternative with enhanced performance characteristics. This device offers a higher gain bandwidth product (16 MHz) compared to the TLC082IDRG4 (10 MHz), enabling improved frequency response in bandwidth-limited applications. The MC33078DR2G maintains the same 8-SOIC (3.90mm) package footprint and operates across -40°C to 85°C. However, the maximum operating temperature is reduced to 85°C, which may restrict use in high-temperature environments. The MC33078DR2G exhibits lower input offset voltage (150 µV) but higher input bias current (300 nA). Active product status ensures availability. This substitute is suitable for applications where extended bandwidth is beneficial and temperature operation does not exceed 85°C.

Tertiary Recommendation: SE5532AD8R2G

The SE5532AD8R2G from onsemi offers extended temperature range operation (-55°C to 125°C), exceeding the TLC082IDRG4 specification. This device maintains the 8-SOIC (3.90mm) package and 10 MHz gain bandwidth product. The SE5532AD8R2G exhibits higher supply current (8 mA versus 1.9 mA) and operates across a wider supply voltage range (6V to 40V). Active product status and ROHS3 compliance are confirmed. This substitute is appropriate for applications requiring extended low-temperature operation or higher supply voltage flexibility.

Alternative Consideration: LM4565F-GE2

The LM4565F-GE2 from Rohm Semiconductor provides the widest supply voltage range (4V to 36V) and highest output current per channel (160 mA). However, this device exhibits significantly lower slew rate (5V/µs versus 19V/µs) and operates only to 85°C maximum temperature. The package width is slightly larger (4.40mm versus 3.90mm), which may require PCB layout verification. This substitute is suitable only for applications where extended supply voltage range and high output drive are prioritized over slew rate performance.

Obsolete Alternative: SC2904VDR2G

The SC2904VDR2G from onsemi shares the 8-SOIC (3.90mm) package configuration but carries obsolete product status. Incomplete electrical parameter documentation (slew rate and supply current not specified) limits engineering confidence. This part should not be selected for new designs or long-term production applications.

Frequently Asked Questions (FAQ)

Q1: Can TLC082IDR be used as a direct replacement for TLC082IDRG4 without circuit modification?

A: Yes. The TLC082IDR is a direct electrical and mechanical equivalent. Both devices feature identical slew rate (19V/µs), gain bandwidth product (10 MHz), input bias current (3 pA), input offset voltage (390 µV), supply voltage range (4.5V to 16V), and operating temperature range (-40°C to 125°C). Both are packaged in 8-SOIC (0.154", 3.90mm width) surface mount configuration. No circuit redesign is required. The primary advantage of TLC082IDR is active product status, ensuring long-term procurement availability.

Q2: What are the key differences between MC33078DR2G and TLC082IDRG4?

A: The MC33078DR2G offers higher gain bandwidth product (16 MHz versus 10 MHz) and lower input offset voltage (150 µV versus 390 µV), providing improved frequency response and precision. However, the MC33078DR2G exhibits significantly higher input bias current (300 nA versus 3 pA), lower slew rate (7V/µs versus 19V/µs), and reduced maximum operating temperature (85°C versus 125°C). The MC33078DR2G requires minimum 10V supply voltage, whereas TLC082IDRG4 operates from 4.5V. Selection depends on application requirements for bandwidth, precision, slew rate, and temperature range.

Q3: Is the LM4565F-GE2 suitable for high-speed signal conditioning applications?

A: No. The LM4565F-GE2 exhibits slew rate of only 5V/µs, significantly lower than TLC082IDRG4 (19V/µs). This reduced slew rate limits the maximum rate of voltage change, making it unsuitable for high-speed transient applications. The LM4565F-GE2 is appropriate for low-frequency, high-output-current applications where extended supply voltage range (4V to 36V) and high output drive (160 mA per channel) are required.

Q4: Can SE5532AD8R2G be used in applications requiring operation below -40°C?

A: Yes. The SE5532AD8R2G operates across -55°C to 125°C, extending the lower temperature limit to -55°C compared to TLC082IDRG4 (-40°C to 125°C). This device is suitable for cryogenic or extreme cold-environment applications. However, the SE5532AD8R2G exhibits higher supply current (8 mA versus 1.9 mA) and requires minimum 6V supply voltage, which may impact power budget and low-voltage system compatibility.

Q5: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts (TLC082IDR, MC33078DR2G, SE5532AD8R2G, LM4565F-GE2, and SC2904VDR2G) are ROHS3 compliant, matching the TLC082IDRG4 regulatory status. All parts carry MSL 1 (Unlimited) moisture sensitivity level and are REACH unaffected. ECCN classification is EAR99 for all devices.

Q6: What is the impact of package width difference between TLC082IDRG4 and LM4565F-GE2?

A: The LM4565F-GE2 is packaged in 8-SOIC with 4.40mm width, compared to 3.90mm width for TLC082IDRG4. This 0.5mm difference may require PCB layout verification, particularly in high-density designs with tight component spacing. Pin pitch and lead configuration remain compatible with standard 8-SOIC footprints, but physical clearance around the device must be confirmed. Consult PCB design guidelines and component datasheets for specific placement constraints.

Q7: Which substitute offers the best low-power performance?

A: The TLC082IDR maintains the lowest supply current (1.9 mA for two channels) identical to TLC082IDRG4. This device is optimal for battery-powered or low-power applications. The MC33078DR2G (4.1 mA) and LM4565F-GE2 (4.5 mA) exhibit moderate power consumption, while SE5532AD8R2G (8 mA) consumes the highest supply current among active substitutes.

Q8: Are there inventory considerations for substitute selection?

A: Yes. Current inventory levels vary significantly: TLC082IDR (1,159 pcs), MC33078DR2G (60,100 pcs), SE5532AD8R2G (8,337 pcs), and LM4565F-GE2 (2,353 pcs). MC33078DR2G offers the highest immediate availability. However, inventory levels are subject to change and should be verified with suppliers for production quantities and lead times.
