TLC080CDGN Equivalent & Substitute Parts

Part Overview

The TLC080CDGN is a general-purpose operational amplifier manufactured by Texas Instruments, housed in an 8-HVSSOP surface mount package. This device is classified as obsolete, which necessitates identification of active equivalent parts for ongoing design and procurement requirements. The TLC080CDGN serves as a single-circuit general-purpose amplifier suitable for applications requiring low input bias current and moderate bandwidth performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC080CDGN is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Amplifier type (General Purpose)
• Number of circuits (1)
• Slew rate (19 V/µs)
• Gain bandwidth product (10 MHz)
• Input bias current (2 pA)
• Input offset voltage (390 µV)
• Supply current (1.9 mA)
• Output current per channel (57 mA)
• Supply voltage range (4.5 V to 16 V)
• Operating temperature range (0°C to 70°C)

Mechanical Compatibility Criteria:

• Surface mount technology
• 8-pin package configuration
• RoHS3 compliance
• Moisture sensitivity level 1

The TLC080CDR qualifies as a direct substitute based on identical electrical specifications and compliance certifications. The primary distinction is packaging format: the TLC080CDR utilizes an 8-SOIC package (0.154", 3.90mm Width) in tape and reel format, whereas the TLC080CDGN uses an 8-HVSSOP package. Both packages accommodate surface mount assembly and maintain full electrical equivalence.

Parameter Comparison

Engineering Selection Recommendations

The TLC080CDR is the qualified substitute for the obsolete TLC080CDGN. Selection of the TLC080CDR is based on the following engineering factors:

Product Status: The TLC080CDGN is classified as obsolete, making the active TLC080CDR the appropriate choice for new designs and ongoing procurement. The TLC080CDR maintains active product status with Texas Instruments.

Electrical Equivalence: All electrical parameters are identical between the two parts, including slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current, and supply voltage range. This ensures functional equivalence in circuit applications.

Compliance Certifications: Both parts maintain ROHS3 compliance and identical moisture sensitivity levels (MSL 1), satisfying regulatory and environmental requirements.

Package Consideration: The TLC080CDR uses an 8-SOIC package instead of the 8-HVSSOP package. PCB layout modifications are required to accommodate the different package footprint and pin spacing. The 8-SOIC package (0.154", 3.90mm Width) has a larger body width than the 8-HVSSOP package (0.118", 3.00mm Width).

Availability: The TLC080CDR is supplied in tape and reel format with higher inventory availability (1940 pieces) compared to the obsolete TLC080CDGN.

Frequently Asked Questions (FAQ)

Q: Can the TLC080CDR directly replace the TLC080CDGN without circuit modifications?

A: The TLC080CDR provides electrical equivalence and can replace the TLC080CDGN functionally. However, PCB layout modifications are required due to package differences. The 8-SOIC package has different pin spacing and body dimensions than the 8-HVSSOP package, necessitating new footprint design and PCB routing.

Q: Are there any electrical performance differences between TLC080CDGN and TLC080CDR?

A: No. Both parts share identical electrical specifications across all measured parameters: slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current, and operating temperature range.

Q: What is the significance of the different package types?

A: The TLC080CDGN uses an 8-HVSSOP package (0.118" width), while the TLC080CDR uses an 8-SOIC package (0.154" width). Both are surface mount packages with 8 pins, but they have different physical dimensions and pin layouts. Component placement, PCB footprint, and routing must be adjusted accordingly.

Q: Does the TLC080CDR meet the same compliance standards as the TLC080CDGN?

A: Yes. Both parts are ROHS3 compliant and have identical moisture sensitivity levels (MSL 1). Regulatory and environmental compliance requirements are maintained.

Q: Why is the TLC080CDGN classified as obsolete?

A: The TLC080CDGN has reached end-of-life status with Texas Instruments. The TLC080CDR remains in active production and is the recommended substitute for new designs and procurement.

Q: What is the difference between tape and reel packaging and other packaging formats?

A: Tape and reel (TR) packaging is a standard format for automated assembly processes, where components are wound on a continuous tape with regular spacing. This format is suitable for high-volume manufacturing and pick-and-place equipment. The TLC080CDR is supplied in tape and reel format, facilitating automated assembly workflows.
