TLC071IP Equivalent & Substitute Parts

Part Overview

The TLC071IP is a general-purpose operational amplifier manufactured by Texas Instruments, housed in an 8-DIP through-hole package. This device is classified as Last Time Buy, indicating discontinued production with limited remaining inventory. The TLC071IP serves applications requiring low-power amplification with moderate bandwidth and precision input characteristics. Identification of equivalent substitute parts is necessary due to product status transition and to support design flexibility across different manufacturing and assembly environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC071IP is determined by electrical parameter equivalence and functional compatibility. The TLC071 series shares a common base product number, indicating identical electrical specifications across package variants. Substitute parts must maintain:

Electrical Parameter Equivalence:

• Slew Rate: 19 V/µs
• Gain Bandwidth Product: 10 MHz
• Input Bias Current: 1.5 pA
• Input Offset Voltage: 390 µV
• Supply Current: 2.1 mA
• Output Current per Channel: 57 mA
• Supply Voltage Range: 4.5 V to 16 V
• Operating Temperature Range: -40°C to 125°C

Functional Equivalence:

• Amplifier Type: General Purpose
• Number of Circuits: 1
• Manufacturer: Texas Instruments
• Base Product Number: TLC071

The primary distinction between the main part and substitute parts lies in packaging format and mounting technology. The TLC071IP uses through-hole mounting (8-DIP), while substitutes may employ surface-mount technology (8-SOIC). Both package types are electrically and functionally equivalent when integrated into appropriate circuit board designs.

Engineering Selection Recommendations

TLC071IDR Selection Criteria:

The TLC071IDR is the manufacturer-recommended substitute for the TLC071IP. This substitution is supported by:

1. Electrical Equivalence: All electrical parameters, including slew rate, gain bandwidth product, bias current, offset voltage, supply current, and output current specifications are identical between the two parts.

2. Product Status: The TLC071IDR maintains Active product status, ensuring continued availability and long-term supply chain stability. The TLC071IP is designated Last Time Buy, indicating production discontinuation.

3. Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH Unaffected status, satisfying environmental and regulatory requirements.

4. Functional Compatibility: Both devices operate across the identical temperature range (-40°C to 125°C) and supply voltage range (4.5 V to 16 V), ensuring functional interchangeability in circuit applications.

5. Package Consideration: The primary difference is packaging format. The TLC071IDR uses 8-SOIC surface-mount technology, while the TLC071IP uses 8-DIP through-hole technology. Selection between these variants depends on circuit board design methodology and assembly capabilities.

Frequently Asked Questions (FAQ)

Q: Are the TLC071IP and TLC071IDR electrically identical?

A: Yes. Both devices share the base product number TLC071 and maintain identical electrical specifications across all measured parameters, including slew rate, bandwidth, bias current, offset voltage, supply current, and output current ratings.

Q: What is the primary difference between these two parts?

A: The primary difference is packaging and mounting technology. The TLC071IP uses an 8-DIP through-hole package (0.300" width), while the TLC071IDR uses an 8-SOIC surface-mount package (0.154" width). The electrical performance is identical.

Q: Why is the TLC071IP marked as Last Time Buy?

A: Last Time Buy designation indicates that Texas Instruments has discontinued production of this part number. Existing inventory is available for purchase, but no future production is planned. The TLC071IDR, with Active status, represents the ongoing product offering.

Q: Can I use the TLC071IDR as a direct replacement for the TLC071IP?

A: Electrical substitution is complete. However, circuit board layout and assembly process must accommodate the different package format. Through-hole designs require modification to surface-mount design, or vice versa.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the TLC071IP and TLC071IDR are ROHS3 compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What is the inventory status of each part?

A: The TLC071IP has 1,330 pieces in stock (Last Time Buy status). The TLC071IDR has 16,570 pieces in stock (Active status), indicating greater long-term availability.

Q: Are there any temperature or supply voltage differences between these parts?

A: No. Both parts operate across the identical temperature range of -40°C to 125°C and support supply voltages from 4.5 V to 16 V minimum to 16 V maximum.
