• Mounting Type: Surface Mount
• Number of Circuits: 1
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Functional Compatibility Criteria:

• Supply voltage range overlap with 4.5V minimum and 16V maximum
• Input bias current performance
• Input offset voltage specification
• Output current capability per channel

The identified substitute parts maintain identical package geometry and mounting characteristics, ensuring mechanical and electrical interface compatibility. Both substitute parts are classified as Active products, providing superior procurement availability compared to the obsolete TLC071CDG4.

Parameter Comparison

Engineering Selection Recommendations

TLC071CD Selection Criteria:

The TLC071CD is the primary direct substitute for the TLC071CDG4. Both devices share identical electrical specifications, including slew rate (19V/µs), gain bandwidth product (10 MHz), input bias current (1.5 pA), and input offset voltage (390 µV). The TLC071CD maintains the same supply voltage range (4.5V to 16V) and output current capability (57 mA per channel). The critical distinction is product status: TLC071CD is classified as Active, ensuring reliable procurement and manufacturing support. Both parts comply with ROHS3 and maintain MSL 1 rating. The TLC071CD is packaged in Tube format, providing standard component handling and storage compatibility.

AD8130ARZ Selection Criteria:

The AD8130ARZ represents an alternative substitute with enhanced performance characteristics. This Analog Devices differential amplifier operates within the same 8-SOIC package footprint and maintains compatibility with the 4.5V minimum supply voltage. The AD8130ARZ provides significantly higher slew rate (1100V/µs versus 19V/µs) and extended bandwidth (-3dB bandwidth of 290 MHz). The operating temperature range extends to -40°C to 85°C, exceeding the TLC071CDG4 specification of 0°C to 70°C. Supply voltage maximum extends to 25.2V. Input offset voltage remains comparable (400 µV). The AD8130ARZ is classified as Active with extensive inventory availability (20,724 pieces). This device is suitable for applications requiring higher frequency response and faster transient performance. Input bias current is specified as 500 nA, which differs from the TLC071CDG4 specification of 1.5 pA.

Compliance and Certification:

All three devices—TLC071CDG4, TLC071CD, and AD8130ARZ—maintain ROHS3 compliance and MSL 1 rating. All devices are classified under ECCN EAR99 and HTSUS 8542.33.0001, ensuring consistent regulatory and export classification.

Frequently Asked Questions (FAQ)

Q1: Why is the TLC071CDG4 classified as obsolete?

A: The TLC071CDG4 is designated as obsolete by Texas Instruments. The TLC071CD, an Active product with identical electrical specifications, is the recommended replacement for new designs and ongoing procurement.

Q2: Can the TLC071CD be used as a direct replacement for the TLC071CDG4?

A: Yes. The TLC071CD is a direct electrical and mechanical substitute. Both devices share identical slew rate (19V/µs), gain bandwidth product (10 MHz), input bias current (1.5 pA), input offset voltage (390 µV), supply voltage range (4.5V to 16V), and output current capability (57 mA per channel). Both are housed in 8-SOIC packages with identical pin configurations and mounting requirements.

Q3: What are the key differences between the TLC071CD and AD8130ARZ?

A: The TLC071CD is a general-purpose amplifier, while the AD8130ARZ is a differential amplifier. The AD8130ARZ provides higher slew rate (1100V/µs versus 19V/µs), extended bandwidth (290 MHz -3dB bandwidth), wider supply voltage range (4.5V to 25.2V), and extended operating temperature range (-40°C to 85°C). Input bias current differs: AD8130ARZ specifies 500 nA compared to TLC071CD's 1.5 pA. Both maintain 8-SOIC package compatibility.

Q4: Are all substitute parts RoHS compliant?

A: Yes. The TLC071CDG4, TLC071CD, and AD8130ARZ are all ROHS3 compliant with MSL 1 rating (Unlimited moisture sensitivity level).

Q5: What is the package compatibility between these devices?

A: All three devices are housed in 8-SOIC packages with identical dimensions (0.154" width, 3.90mm width). All are surface mount components with identical pin configurations, ensuring direct PCB layout compatibility.

Q6: Which substitute should be selected for new designs?

A: For applications requiring general-purpose amplification with the original TLC071CDG4 specifications, the TLC071CD is the appropriate selection due to its Active product status and identical electrical characteristics. For applications requiring higher bandwidth, faster slew rate, or extended temperature range, the AD8130ARZ is suitable, provided the differential amplifier topology and higher input bias current (500 nA) are compatible with the circuit design.

Q7: What is the inventory status of these parts?

A: TLC071CDG4 has 1,036 pieces in stock (obsolete status). TLC071CD has 901 pieces in stock (Active status). AD8130ARZ has 20,724 pieces in stock (Active status), providing superior long-term availability.

Q8: Do these devices require different PCB layout considerations?

A: No. All three devices share identical 8-SOIC package geometry and surface mount requirements. PCB layouts designed for the TLC071CDG4 are directly compatible with both the TLC071CD and AD8130ARZ without modification.
