OPA363IDR Equivalent & Substitute Parts

Part Overview

The OPA363IDR is a general-purpose operational amplifier manufactured by Texas Instruments, housed in an 8-SOIC surface mount package. This device features rail-to-rail output capability, making it suitable for low-voltage analog signal processing applications. The OPA363IDR is classified as obsolete, which necessitates identification of equivalent substitute components for ongoing design support and procurement continuity. The substitute part maintains identical electrical performance and mechanical compatibility while offering active product status and improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OPA363IDR with the OPA363ID is based on electrical and mechanical parameter equivalence. Both components share identical specifications across all critical performance parameters: amplifier type, circuit count, output configuration, slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current capability, supply voltage range, and operating temperature range. Both devices utilize the same 8-SOIC surface mount package with identical physical dimensions (0.154" width, 3.90mm). Compliance certifications including RoHS3 and moisture sensitivity level are identical between the two parts.

The primary distinction between OPA363IDR and OPA363ID is product status and packaging format. The OPA363IDR is classified as obsolete, while the OPA363ID maintains active product status. The OPA363ID is supplied in tube packaging, whereas the OPA363IDR packaging specification is not defined in available documentation. This substitution is valid for all applications where the OPA363IDR was previously specified, provided that tube packaging is acceptable for the procurement and assembly workflow.

Parameter Comparison

Engineering Selection Recommendations

The OPA363ID is the direct substitute for the OPA363IDR. Selection of the OPA363ID is appropriate for all applications previously designed with the OPA363IDR. The substitute part provides identical electrical performance and mechanical compatibility while offering the advantage of active product status, ensuring long-term availability and supply chain continuity.

Both components maintain ROHS3 compliance and identical moisture sensitivity specifications, satisfying regulatory and environmental requirements. The OPA363ID is supplied in tube packaging, which is standard for surface mount components in production environments. Designs currently utilizing the OPA363IDR can transition to the OPA363ID without modification to schematic, layout, or assembly procedures.

The availability advantage of the OPA363ID (4242 pieces in stock versus 890 pieces for the OPA363IDR) supports procurement planning for new production runs and ongoing support of fielded systems.
