TLC081CP Equivalent & Substitute Parts

Part Overview

The TLC081CP is a general-purpose operational amplifier manufactured by Texas Instruments, housed in an 8-DIP through-hole package. This device functions as a single-circuit amplifier suitable for analog signal processing applications requiring moderate bandwidth and low input bias current. The TLC081CP is classified as Last Time Buy, indicating discontinued production status. Identifying equivalent substitute parts is necessary for design continuity, procurement flexibility, and long-term product support when through-hole packaging is not a requirement or when surface-mount alternatives are preferred.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC081CP is determined by electrical parameter equivalence across the following critical specifications:

Electrical Equivalence Criteria:

• Slew Rate: 19 V/µs
• Gain Bandwidth Product: 10 MHz
• Current - Input Bias: 2 pA
• Voltage - Input Offset: 390 µV
• Current - Supply: 1.9 mA
• Current - Output / Channel: 57 mA
• Voltage - Supply Span: 4.5 V to 16 V
• Operating Temperature Range: 0°C to 70°C
• Number of Circuits: 1
• Amplifier Type: General Purpose

Packaging Consideration: The TLC081CP is specified in 8-DIP through-hole packaging. The primary substitute, TLC081CDR, maintains identical electrical performance but is offered in 8-SOIC surface-mount packaging. This substitution is valid when circuit board design accommodates surface-mount technology and when the functional requirements of the application remain unchanged.

Parameter Comparison

Engineering Selection Recommendations

TLC081CDR Selection Basis:

The TLC081CDR is the direct electrical equivalent of the TLC081CP, manufactured by Texas Instruments under the same base product number (TLC081). All electrical parameters—including slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current, and supply voltage range—are identical across both devices.

The primary distinction is packaging format: TLC081CP uses through-hole 8-DIP mounting, while TLC081CDR uses surface-mount 8-SOIC packaging. This difference requires circuit board redesign if transitioning between the two variants.

Compliance Status: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent substitution.

Product Status Consideration: The TLC081CP is designated Last Time Buy, indicating end-of-life status. The TLC081CDR maintains Active product status, ensuring continued availability and long-term supply chain reliability. Selection of TLC081CDR is recommended for new designs or production continuity when surface-mount technology is feasible.

Frequently Asked Questions (FAQ)

Q: Can TLC081CDR directly replace TLC081CP in an existing circuit?

A: Electrical substitution is complete; all performance parameters are identical. However, physical substitution requires circuit board modification because TLC081CP uses through-hole 8-DIP packaging while TLC081CDR uses surface-mount 8-SOIC packaging. Schematic compatibility is 100%, but PCB layout changes are mandatory.

Q: What are the key electrical parameters that define substitution eligibility?

A: Substitution is valid when the following parameters match: 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), and supply voltage range (4.5 V to 16 V). All these parameters are identical between TLC081CP and TLC081CDR.

Q: Why is TLC081CP marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of this part number. Existing inventory may be available through authorized distributors, but long-term availability is not guaranteed. TLC081CDR, with Active status, is the recommended path for sustained production requirements.

Q: Are there compliance or certification differences between these parts?

A: No. Both TLC081CP and TLC081CDR are ROHS3 compliant and REACH unaffected. Regulatory compliance is equivalent, and both parts carry identical ECCN (EAR99) and HTSUS (8542.33.0001) classifications.

Q: What is the moisture sensitivity level difference?

A: TLC081CP lists MSL as Not Applicable (through-hole package). TLC081CDR specifies MSL 1 (Unlimited), which is standard for surface-mount packages and indicates no moisture sensitivity restrictions during storage or handling.

Q: Can I use TLC081CDR in a through-hole socket designed for TLC081CP?

A: No. The physical package formats are incompatible. TLC081CP is 8-DIP with 0.300" (7.62mm) spacing; TLC081CDR is 8-SOIC with 0.154" (3.90mm) width. A surface-mount adapter or PCB redesign is required for physical integration.
