TLC083IN Equivalent & Substitute Parts

Part Overview

The TLC083IN is a general-purpose operational amplifier manufactured by Texas Instruments, configured as a 2-circuit IC in 14-DIP through-hole packaging. This device is classified as Last Time Buy, indicating discontinued production with limited remaining inventory. The TLC083IN serves applications requiring dual-channel amplification with low input bias current and moderate bandwidth characteristics. Identification of equivalent substitute parts is necessary due to product status transition and to support design flexibility across different mounting technologies and operating temperature ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC083IN is determined by electrical parameter equivalence and functional compatibility. The substitute part TLC083CDR shares the identical base product number (TLC083) and maintains all critical electrical specifications: slew rate (19 V/µs), gain bandwidth product (10 MHz), input bias current (3 pA), input offset voltage (390 µV), supply current (1.9 mA per channel), and output current per channel (57 mA). Supply voltage range remains constant at 4.5 V to 16 V.

The primary distinction between the main part and substitute lies in three parameters:

1. Mounting Technology: TLC083IN uses through-hole mounting (14-DIP); TLC083CDR uses surface-mount technology (14-SOIC)
2. Operating Temperature Range: TLC083IN operates from -40°C to 125°C; TLC083CDR operates from 0°C to 70°C
3. Packaging Format: TLC083IN is supplied in Tube; TLC083CDR is supplied in Tape & Reel (TR)
4. Product Status: TLC083IN is Last Time Buy; TLC083CDR is Active

Substitution is valid when the application's temperature requirements fall within 0°C to 70°C and the PCB design accommodates surface-mount 14-SOIC packaging.

Parameter Comparison

Engineering Selection Recommendations

For TLC083IN (Through-Hole DIP Package): Select this part when the application requires through-hole mounting technology, extended operating temperature range (-40°C to 125°C), or when existing PCB designs are committed to 14-DIP footprints. Note that this part carries Last Time Buy status, indicating limited future availability. Current inventory is 1,568 pieces.

For TLC083CDR (Surface-Mount SOIC Package): Select this part when the application operates within the 0°C to 70°C temperature range and the PCB design uses surface-mount technology. This part is Active status with ongoing manufacturing support. Current inventory is 971 pieces. The 14-SOIC package provides smaller board footprint (0.154" width versus 0.300" for DIP) and is compatible with automated assembly processes.

Both parts maintain identical electrical performance specifications and comply with ROHS3 and REACH requirements. Selection between them depends on PCB assembly technology, temperature operating range requirements, and long-term supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can TLC083CDR directly replace TLC083IN in an existing design?

A: Electrical substitution is valid only if the application's operating temperature range falls within 0°C to 70°C. PCB layout modification is required because TLC083CDR uses 14-SOIC surface-mount packaging while TLC083IN uses 14-DIP through-hole packaging. The footprints are not compatible without redesign.

Q: What are the key electrical differences between TLC083IN and TLC083CDR?

A: There are no electrical differences. Both parts share identical specifications for slew rate (19 V/µs), gain bandwidth product (10 MHz), input bias current (3 pA), input offset voltage (390 µV), supply current (1.9 mA per channel), output current (57 mA per channel), and supply voltage range (4.5 V to 16 V).

Q: Why does TLC083CDR have a narrower operating temperature range?

A: The operating temperature range difference (-40°C to 125°C for TLC083IN versus 0°C to 70°C for TLC083CDR) reflects the thermal specifications of the respective package types. This is a package-level characteristic, not an electrical limitation of the die itself.

Q: What is the significance of TLC083IN being Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of the TLC083IN. Existing inventory will be depleted without replenishment. For new designs or long-term production requirements, TLC083CDR (Active status) is the recommended alternative if temperature and packaging requirements permit.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both TLC083IN and TLC083CDR are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What packaging quantities are available?

A: TLC083IN is supplied in Tube packaging; TLC083CDR is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for surface-mount components and supports automated pick-and-place assembly.
