TLC085CD Equivalent & Substitute Parts

Part Overview

The TLC085CD is a general-purpose operational amplifier integrated circuit manufactured by Texas Instruments, configured as a 4-circuit device in a 16-SOIC surface mount package. This component is classified as obsolete, indicating discontinued production and limited availability for new designs. The TLC085CD operates across a supply voltage range of 4.5V to 16V with an operating temperature range of 0°C to 70°C, making it suitable for legacy applications and maintenance scenarios where component replacement is required.

Due to its obsolete status, identifying equivalent and substitute parts is necessary for system maintenance, repair operations, and design continuity. Substitute components must maintain functional compatibility while meeting or exceeding the electrical performance specifications of the original device.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the TLC085CD is determined by the following critical parameters:

Functional Requirements:

• Amplifier Type: General Purpose
• Number of Circuits: 4 (quad configuration)
• Package / Case: 16-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount

Electrical Performance Boundaries:

• Voltage Supply Range: Substitute must support minimum 4.5V operation
• Slew Rate: Substitute performance at 19V/µs or higher maintains signal integrity
• Gain Bandwidth Product: Substitute at 10 MHz or higher preserves frequency response
• Current Output per Channel: Substitute at 57 mA or higher ensures load driving capability

Compliance & Environmental:

• RoHS3 Compliance required
• Moisture Sensitivity Level 1 (Unlimited) acceptable
• REACH Unaffected status maintained

The LT1214CS#PBF from Analog Devices Inc. qualifies as a substitute based on matching functional architecture (4-circuit general-purpose amplifier in 16-SOIC package) while exceeding electrical performance specifications across slew rate, gain bandwidth product, and supply voltage range.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The LT1214CS#PBF is a direct functional substitute for the TLC085CD based on matching package geometry, circuit configuration, and mounting technology. Both devices are RoHS3 compliant with MSL 1 rating, ensuring regulatory and environmental compatibility.

Product Status Consideration:

The TLC085CD is classified as obsolete, while the LT1214CS#PBF maintains active production status. This distinction is significant for long-term supply chain reliability and technical support availability. The LT1214CS#PBF is recommended for applications requiring sustained component availability and manufacturer support.

Electrical Performance:

The LT1214CS#PBF demonstrates enhanced electrical characteristics across multiple parameters:

• Gain Bandwidth Product increased from 10 MHz to 28 MHz
• Voltage - Input Offset reduced from 390 µV to 150 µV
• Operating temperature range expanded from 0–70°C to -40–85°C
• Supply voltage range extended from 4.5–16V to 2.5–36V

These improvements provide superior performance margins and operational flexibility. The LT1214CS#PBF operates at higher supply current (3.4 mA vs. 1.9 mA) but maintains output current capability at 50 mA per channel, which meets the 57 mA requirement of the original design.

Compliance Status:

Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can the LT1214CS#PBF directly replace the TLC085CD in existing PCB designs?

A: Yes. Both devices utilize identical 16-SOIC package geometry (0.154", 3.90mm width) and surface mount configuration. Pin-to-pin compatibility is maintained, allowing direct substitution without PCB layout modifications.

Q: What are the primary electrical differences between these devices?

A: The LT1214CS#PBF provides higher gain bandwidth product (28 MHz vs. 10 MHz), lower input offset voltage (150 µV vs. 390 µV), and extended supply voltage range (2.5–36V vs. 4.5–16V). The LT1214CS#PBF operates at higher supply current (3.4 mA vs. 1.9 mA) but maintains adequate output current per channel.

Q: Is the LT1214CS#PBF suitable for applications originally designed for the TLC085CD?

A: Yes. The LT1214CS#PBF meets or exceeds all critical performance parameters of the TLC085CD. The enhanced specifications provide additional design margin and operational flexibility. Applications operating within the original TLC085CD specifications will function correctly with the LT1214CS#PBF.

Q: What is the significance of the TLC085CD being classified as obsolete?

A: Obsolete status indicates discontinued production by the manufacturer. Component availability is limited to existing inventory. The LT1214CS#PBF, with active production status, provides assured long-term supply chain continuity and manufacturer technical support.

Q: Are there packaging differences between the TLC085CD and LT1214CS#PBF?

A: Both devices are supplied in 16-SOIC surface mount packages with identical physical dimensions. The TLC085CD is supplied in standard packaging, while the LT1214CS#PBF is supplied in tube packaging. This difference does not affect electrical performance or PCB assembly compatibility.

Q: Do both devices meet the same regulatory compliance standards?

A: Yes. Both the TLC085CD and LT1214CS#PBF are RoHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Regulatory requirements for industrial and commercial applications are satisfied by either component.

Q: What is the operating temperature range difference, and does it matter for my application?

A: The TLC085CD operates from 0°C to 70°C, while the LT1214CS#PBF operates from -40°C to 85°C. If your application operates within the 0–70°C range, both devices are suitable. The LT1214CS#PBF provides extended temperature capability for applications requiring operation outside this range.

Q: How does the supply voltage range difference affect substitution?

A: The TLC085CD requires 4.5–16V supply, while the LT1214CS#PBF operates from 2.5–36V. If your design supplies 4.5–16V, both devices function correctly. The LT1214CS#PBF accommodates lower supply voltages (2.5V) and higher voltages (up to 36V), providing additional design flexibility.
