OPA363AIDR Equivalent & Substitute Parts

Part Overview

The OPA363AIDR is a general-purpose operational amplifier manufactured by Texas Instruments, designed for rail-to-rail applications in 8-SOIC surface mount packaging. This device is classified as obsolete, which necessitates identification of equivalent substitute components for ongoing design support and production continuity. The OPA363AIDR delivers 1 circuit with a 7 MHz gain bandwidth product and 5 V/µs slew rate, suitable for low-power analog signal conditioning applications requiring supply voltages between 1.8 V and 5.5 V.

Parameter Comparison

Engineering Selection Recommendations

The OPA363AID serves as a direct functional equivalent to the OPA363AIDR. Both components share identical electrical specifications, physical packaging, and environmental operating parameters. The primary distinction is product status: the OPA363AIDR is classified as obsolete, while the OPA363AID maintains active status with Texas Instruments.

For new designs and production continuity, the OPA363AID is the appropriate selection. This substitute maintains full compatibility with existing circuit designs without requiring modifications to PCB layouts, schematic connections, or firmware parameters. Both parts comply with ROHS3 and REACH regulations, ensuring regulatory alignment across supply chain transitions.

The OPA363AID is supplied in tube packaging, which differs from the OPA363AIDR specification. Verify packaging requirements against procurement and assembly processes to confirm compatibility with existing handling and placement equipment.

Frequently Asked Questions (FAQ)

Q: Can the OPA363AID directly replace the OPA363AIDR without circuit modifications?

A: Yes. The OPA363AID is electrically and mechanically identical to the OPA363AIDR across all specified parameters. No circuit redesign, PCB layout changes, or component value adjustments are required for direct substitution.

Q: What is the primary reason for substituting the OPA363AIDR?

A: The OPA363AIDR is classified as obsolete. The OPA363AID provides equivalent functionality with active product status, ensuring long-term availability and supply chain reliability.

Q: Are there any differences in packaging between these two parts?

A: Both parts use 8-SOIC (0.154", 3.90mm Width) surface mount packaging. The OPA363AID is supplied in tube packaging, while the OPA363AIDR packaging specification is not detailed. Confirm tube packaging compatibility with your assembly process.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the OPA363AIDR and OPA363AID are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements.

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

A: Substitution is determined by matching gain bandwidth product (7 MHz), slew rate (5 V/µs), supply voltage range (1.8 V to 5.5 V), output type (rail-to-rail), input bias current (1 pA), input offset voltage (1 mV), supply current (1.1 mA), and output current per channel (85 mA).

Q: Is the OPA363AID suitable for the same operating temperature range?

A: Yes. Both parts operate across the identical temperature range of -40°C to 125°C, ensuring thermal compatibility in all specified applications.

Q: What is the moisture sensitivity level for both parts?

A: Both parts have a Moisture Sensitivity Level (MSL) of 2 with a 1-year floor life rating, requiring identical handling and storage protocols.
