OPA182IDT Equivalent & Substitute Parts

Part Overview

The OPA182IDT is a zero-drift operational amplifier manufactured by Texas Instruments, designed for precision analog signal conditioning applications. This single-channel, rail-to-rail amplifier operates across a wide supply voltage range of 4.5 V to 36 V and delivers a gain-bandwidth product of 5 MHz with exceptionally low input offset voltage of 0.45 µV. The device is packaged in an 8-SOIC surface-mount configuration and maintains active product status with full availability. Substitute parts are identified to address packaging format preferences, inventory availability, and equivalent electrical performance requirements in production environments.

Substitute Part Grouping Explanation

Substitution of the OPA182IDT is determined by electrical parameter equivalence and mechanical compatibility. The primary substitute identified is the OPA182IDR, which maintains identical electrical specifications across all critical performance metrics: zero-drift amplifier topology, 5 MHz gain-bandwidth product, 0.45 µV input offset voltage, 10 V/µs slew rate, and full supply voltage range of 4.5 V to 36 V. Both devices are packaged in the 8-SOIC surface-mount configuration with matching thermal and mechanical characteristics.

The distinction between OPA182IDT and OPA182IDR is limited to packaging format: OPA182IDT is supplied in Tape & Reel (TR) format, while OPA182IDR is supplied in Cut Tape (CT) and Digi-Reel® format. This difference addresses supply chain flexibility and procurement preferences without affecting circuit performance or board-level integration.

Substitution eligibility is based on the following key parameters:

• Amplifier Type: Zero-Drift
• Number of Circuits: 1
• Output Type: Rail-to-Rail
• Gain Bandwidth Product: 5 MHz
• Voltage - Input Offset: 0.45 µV
• Voltage - Supply Span: 4.5 V to 36 V
• Package / Case: 8-SOIC
• Mounting Type: Surface Mount
• Operating Temperature Range: -40°C to 125°C

Parameter Comparison

Engineering Selection Recommendations

Both OPA182IDT and OPA182IDR are active products from Texas Instruments with identical electrical performance specifications and mechanical compatibility. Selection between these parts is determined by packaging and supply chain requirements rather than functional differences.

OPA182IDT (Tape & Reel format) is appropriate for high-volume automated assembly operations where continuous reel feeding into pick-and-place equipment is standard practice. This format minimizes handling and optimizes production throughput.

OPA182IDR (Cut Tape & Digi-Reel® format) is appropriate for mixed-volume production, prototyping, and applications where flexible packaging options support variable order quantities and inventory management strategies.

Both devices maintain identical compliance status, moisture sensitivity classification, and operating specifications across the full temperature range of -40°C to 125°C. No functional or reliability differences exist between the two packaging formats.

Frequently Asked Questions (FAQ)

Q: Can OPA182IDR be used as a direct replacement for OPA182IDT in production?

A: Yes. The OPA182IDR is electrically and mechanically identical to the OPA182IDT. The only difference is the packaging format (Cut Tape & Digi-Reel® versus Tape & Reel). Both devices are pin-compatible, have identical footprints, and deliver the same electrical performance. Substitution is valid for any application where OPA182IDT is specified.

Q: Are there any differences in electrical performance between OPA182IDT and OPA182IDR?

A: No. Both parts are manufactured by Texas Instruments with identical specifications for gain-bandwidth product (5 MHz), input offset voltage (0.45 µV), slew rate (10 V/µs), supply voltage range (4.5 V to 36 V), and operating temperature range (-40°C to 125°C). Electrical performance is equivalent.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) format supplies components on a continuous reel suitable for automated high-speed assembly lines. Cut Tape (CT) and Digi-Reel® format provides components in tape segments or alternative reel configurations, offering flexibility for lower-volume production and mixed-component assembly. Both formats contain identical components with the same electrical and mechanical properties.

Q: Are both parts available in the same 8-SOIC package?

A: Yes. Both OPA182IDT and OPA182IDR use the 8-SOIC package with 0.154" width (3.90mm). The physical dimensions, pin configuration, and PCB footprint are identical, ensuring direct substitution without layout modifications.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: Both OPA182IDT and OPA182IDR have an MSL rating of 2 with a 1-year shelf life. This classification indicates standard moisture handling requirements for surface-mount components. Storage in controlled humidity environments and proper handling procedures apply to both parts equally.

Q: Can these parts be used interchangeably in the same circuit design?

A: Yes. The OPA182IDT and OPA182IDR are fully interchangeable from a circuit design perspective. No schematic changes, PCB layout modifications, or design verification are required when substituting between these two part numbers. Both deliver identical functional performance in any application.
