TLC081CDR Equivalent & Substitute Parts
Part Overview
The TLC081CDR is a general-purpose operational amplifier manufactured by Texas Instruments, housed in an 8-SOIC surface-mount package. This single-circuit amplifier operates across a 4.5V to 16V supply range with a 10 MHz gain-bandwidth product and 19V/µs slew rate, designed for general analog signal processing applications. The device is Active status and RoHS3 compliant with unlimited moisture sensitivity rating.
Substitute parts are identified when equivalent electrical performance can be achieved within the specified parameter ranges while maintaining compatible packaging and operational characteristics. Alternative models may be required due to inventory availability, specific application performance requirements, or manufacturing discontinuation planning.

Engineering Selection Recommendations
Surface-Mount 8-SOIC Package Substitutes (Direct Footprint Compatibility):
AD8001ARZ and AD8001ARZ-REEL7 provide direct 8-SOIC package compatibility with the TLC081CDR. Both devices are Active status, RoHS3 compliant, and feature unlimited moisture sensitivity. The AD8001ARZ-REEL7 variant is supplied in Tape & Reel packaging, matching the TLC081CDR distribution format. These current-feedback amplifiers deliver 1200V/µs slew rate and 715 MHz bandwidth, substantially exceeding the TLC081CDR performance envelope. Supply voltage range is 6V to 12V, requiring verification that application circuits do not exceed 12V maximum. Operating temperature range extends to 85°C maximum, suitable for industrial applications within this thermal window.
AD8000YRDZ and AD8000YRDZ-REEL7 offer enhanced performance with 4100V/µs slew rate and 1.58 GHz bandwidth in 8-SOIC-EP (exposed pad) configuration. The exposed pad variant provides improved thermal dissipation for high-current applications. Supply voltage compatibility extends to 4.5V minimum, matching the TLC081CDR lower limit. Moisture sensitivity level is 3 (168 hours), requiring controlled storage conditions. The REEL7 variant maintains Tape & Reel packaging format.
High-Performance Surface-Mount Alternatives:
AD8000YCPZ-REEL7 provides 8-LFCSP (3x3) compact package with 4100V/µs slew rate and 1.35 GHz bandwidth. This miniature form factor reduces PCB footprint while delivering superior performance. Moisture sensitivity level 3 requires bake-out procedures before reflow soldering. Supply voltage range 4.5V to 12V is compatible with most TLC081CDR applications.
AD8001ARTZ-REEL7 and AD8005ARTZ-REEL7 are miniature SOT-23-5 surface-mount packages. AD8001ARTZ-REEL7 maintains 1200V/µs slew rate and 795 MHz bandwidth with 6V to 12V supply range. AD8005ARTZ-REEL7 offers lower power consumption (400µA supply current) and reduced output current (10mA) with 280V/µs slew rate and 270 MHz bandwidth, suitable for battery-powered or low-power applications.
Through-Hole Package Alternatives:
5962-9459301MPA, AD8001ANZ, and AD8001AQ provide through-hole mounting in 8-CDIP or 8-DIP packages for legacy PCB designs. All three maintain 1200V/µs slew rate and deliver 380 MHz to 880 MHz bandwidth. Supply voltage range is 6V to 12V. The 5962-9459301MPA variant extends operating temperature to -55°C to 125°C, suitable for military or extended-temperature applications.
Compliance and Regulatory Status:
All identified substitute parts maintain Active product status and RoHS3 compliance. REACH status is unaffected for all variants. ECCN classification is EAR99 for all parts. Moisture sensitivity levels range from 1 (unlimited) to 3 (168 hours), with level 3 parts requiring controlled storage and bake-out procedures per IPC-A-610 standards.
Frequently Asked Questions (FAQ)
Q: Can AD8000YRDZ directly replace TLC081CDR in existing PCB designs?
A: AD8000YRDZ shares the 8-SOIC package footprint with TLC081CDR and is pin-compatible for standard operational amplifier configurations. However, the exposed pad (-EP) variant requires PCB layout modification to connect the thermal pad. Verify that application supply voltage does not exceed 12V maximum, as AD8000YRDZ maximum supply is 12V compared to TLC081CDR maximum of 16V. Moisture sensitivity level 3 requires bake-out before reflow soldering.
Q: What is the difference between AD8001ARZ and AD8001ARZ-REEL7?
A: Both parts are electrically identical with matching performance specifications. The primary difference is packaging format: AD8001ARZ is supplied in Tube packaging, while AD8001ARZ-REEL7 is supplied in Cut Tape with Digi-Reel format. Selection depends on assembly line requirements and inventory management preferences. Both maintain unlimited moisture sensitivity and RoHS3 compliance.
Q: Why do substitute parts show higher slew rates and bandwidth than TLC081CDR?
A: Identified substitutes employ current-feedback amplifier topology, which inherently delivers superior slew rate and bandwidth performance compared to the general-purpose voltage-feedback architecture of TLC081CDR. Current-feedback design provides 1200V/µs to 4100V/µs slew rates versus 19V/µs for TLC081CDR. This performance enhancement is available without cost or package size penalty, making current-feedback amplifiers suitable for applications requiring higher-speed signal processing.
Q: Are there supply voltage compatibility issues when substituting TLC081CDR?
A: Yes. TLC081CDR operates across 4.5V to 16V supply range. Most identified substitutes limit maximum supply to 12V. Applications requiring supply voltages between 12V and 16V cannot use these substitutes without circuit redesign. Verify application supply voltage specifications before part selection. AD8000YRDZ and AD8000YCPZ-REEL7 maintain 4.5V minimum supply compatibility.
Q: What is moisture sensitivity level 3, and how does it affect handling?
A: Moisture sensitivity level 3 indicates the component absorbs moisture during storage and requires bake-out at 125°C for 24 hours before reflow soldering. Failure to bake-out can result in delamination or cracking during thermal cycling. Parts with level 1 (unlimited) rating, such as AD8001ARZ and AD8001ARZ-REEL7, do not require bake-out procedures and simplify manufacturing logistics.
Q: Can AD8005ARTZ-REEL7 replace TLC081CDR in all applications?
A: AD8005ARTZ-REEL7 is suitable only for applications where reduced bandwidth (270 MHz) and lower output current (10mA) are acceptable. This part is optimized for low-power, battery-powered applications with supply current of 400µA. Applications requiring the full 57mA output current or higher bandwidth of TLC081CDR must select alternative substitutes such as AD8001ARZ or AD8000YRDZ.
Q: What package options are available for surface-mount applications?
A: Surface-mount substitutes are available in four package types: 8-SOIC (AD8001ARZ, AD8001ARZ-REEL7, AD8000YRDZ, AD8000YRDZ-REEL7), 8-SOIC-EP with exposed pad (AD8000YRDZ variants), 8-LFCSP compact (AD8000YCPZ-REEL7), and SOT-23-5 miniature (AD8001ARTZ-REEL7, AD8005ARTZ-REEL7). Select based on PCB footprint requirements and thermal dissipation needs.
Q: Are all substitute parts RoHS3 compliant?
A: Yes. All identified substitute parts maintain RoHS3 compliance and REACH unaffected status. ECCN classification is EAR99 for all variants, consistent with TLC081CDR regulatory classification.
