TLC070CD Equivalent & Substitute Parts

Part Overview

The TLC070CD is a general-purpose operational amplifier manufactured by Texas Instruments, housed in an 8-SOIC surface mount package. This device is classified as Last Time Buy, indicating discontinued production with limited availability. The TLC070CD serves applications requiring low-power amplification with moderate bandwidth and precision input characteristics. Identification of equivalent and substitute parts is necessary due to product status transition and to ensure design continuity for new production runs or inventory replenishment.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLC070CD is determined by the following critical parameters:

Mechanical Compatibility:

• Package type: 8-SOIC surface mount form factor
• Pin count and pitch: 8 pins, 0.154" width (3.90mm)
• Mounting method: Surface mount technology

Electrical Compatibility:

• Supply voltage range: Minimum 4.5 V, Maximum 16 V
• Operating temperature range: 0°C to 70°C
• Single amplifier circuit configuration
• Output drive capability: 57 mA per channel minimum

Performance Parameters:

• Slew rate: 19 V/µs or greater
• Gain bandwidth product: 10 MHz or greater
• Input bias current: 1.5 pA or lower
• Input offset voltage: 390 µV or lower
• Supply current: 2.1 mA or lower

Two substitute parts meet the mechanical and electrical requirements for direct substitution:

1. TLC070CDR (Texas Instruments) — Identical electrical specifications with alternative packaging (Tape & Reel)
2. AD8130ARZ-REEL7 (Analog Devices Inc.) — Meets mechanical compatibility and exceeds performance specifications

Parameter Comparison

Engineering Selection Recommendations

TLC070CDR Selection Criteria:

The TLC070CDR is the primary substitute for the TLC070CD. Both devices are manufactured by Texas Instruments and share identical electrical and performance specifications. The TLC070CDR differs only in packaging format (Tape & Reel versus Tube). Selection of TLC070CDR is appropriate when:

• Direct functional equivalence is required
• Existing circuit designs and PCB layouts are unchanged
• Supply chain continuity with Texas Instruments products is preferred
• The device is in Active product status, ensuring long-term availability

AD8130ARZ-REEL7 Selection Criteria:

The AD8130ARZ-REEL7 is a secondary substitute manufactured by Analog Devices Inc. This device exceeds the performance specifications of the TLC070CD in multiple parameters: slew rate (1100 V/µs versus 19 V/µs), gain bandwidth product (290 MHz versus 10 MHz), and maximum supply voltage (25.2 V versus 16 V). Selection of AD8130ARZ-REEL7 is appropriate when:

• Enhanced performance margins are beneficial to circuit operation
• Extended operating temperature range (-40°C to 85°C) is required
• Higher supply voltage capability supports system architecture changes
• Differential amplifier topology is compatible with application requirements

Both substitute parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring regulatory and environmental compatibility with the original TLC070CD.

Frequently Asked Questions (FAQ)

Q1: Can TLC070CDR be used as a direct replacement for TLC070CD in existing designs?

A: Yes. The TLC070CDR is electrically and functionally identical to the TLC070CD. Both devices share the same 8-SOIC package, pin configuration, electrical specifications, and performance characteristics. The only difference is packaging format (Tape & Reel versus Tube). No circuit modifications or PCB layout changes are required.

Q2: What are the key differences between TLC070CDR and AD8130ARZ-REEL7?

A: The primary differences are manufacturer (Texas Instruments versus Analog Devices Inc.), amplifier topology (general-purpose versus differential), and performance specifications. The AD8130ARZ-REEL7 provides significantly higher slew rate (1100 V/µs), bandwidth (290 MHz), and maximum supply voltage (25.2 V). However, it draws higher supply current (13 mA versus 2.1 mA) and has higher input bias current (500 nA versus 1.5 pA).

Q3: Is the AD8130ARZ-REEL7 suitable for low-power applications?

A: The AD8130ARZ-REEL7 is not optimal for power-constrained applications. Its supply current of 13 mA is approximately 6 times higher than the TLC070CD (2.1 mA). Applications with strict power budgets should retain the TLC070CDR as the substitute choice.

Q4: Are all three parts compatible with the same PCB layout?

A: Yes. All three parts use the 8-SOIC surface mount package with identical pin spacing and dimensions (0.154" width, 3.90mm). PCB layouts and footprints are interchangeable without modification.

Q5: What is the significance of the TLC070CD being "Last Time Buy"?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of the TLC070CD. Existing inventory is limited (1267 Pcs reported). The TLC070CDR, which is in Active status with higher inventory (1340 Pcs), is the recommended path for future procurement to ensure supply continuity.

Q6: Do all substitute parts meet RoHS and REACH compliance?

A: Yes. Both TLC070CDR and AD8130ARZ-REEL7 are ROHS3 compliant and REACH unaffected, matching the compliance status of the original TLC070CD.

Q7: What packaging formats are available for each part?

A: TLC070CD is supplied in Tube format. TLC070CDR is supplied in Tape & Reel (TR) format. AD8130ARZ-REEL7 is supplied in Cut Tape (CT) and Digi-Reel format. Selection depends on production volume and assembly equipment compatibility.
